Pricing Advice

What users are saying about Oracle Exadata pricing:
  • "It is an expensive product and you pay more for certain performance enhancements."
  • "I did note that Oracle does tend to internally oversize things especially if they want to fill up a budget, and hence third-party oversight is essential."
  • "The majority of our customers are in government or big enterprises, and the projects that we sell come out to several million USD. With this amount of money on the table, it's always better to have an experienced team of consultants, who know Exadata very well, handle the implementation."

High performing and reliable work environment.

Pros and Cons

  • "Oracle Exadata's performance is one of its best features. We very satisfied with it."
  • "There is a feature for security, but it is not included in the first purchase of this solution. That means if you need to increase the security, you need to buy the security feature which doesn't come by default on these solutions."

What is our primary use case?

As we are a service provider for the government our job is to stabilize the database layer. We need to make sure all our data is secure. That's why we like to work with a robust environment like Exadata to make sure that our response time and our reliability are good.

What is most valuable?

Oracle Exadata's performance is one of its best features. We very satisfied with it. The previous equipment used to make a payment for all the government employees used to take at least two days for some of the transactions. Now, it will take hours to make the same amount of payments. Another thing is the flexibility to organize all of our databases. We can use it with new features that come with this version of Oracle 19c, which is the container database. With container databases, we can work with many databases, organized and segregated, and still access the functions and management, the things that most of the technical people like to have in place.

What needs improvement?

Regarding the technical side of the machine itself, I don't see much that needs improvement. In terms of the kind of service and support that most of the clients need, it is huge investments. I would like to emphasize that the clients that use these technologies from Oracle must be well supported by the Oracle company. This is one thing that I would like to address. They could have better support.

Additionally, the price for the Exadata is quite high. This is one thing that Oracle must think about. You can find the same features and the same performance that Oracle provides in other kinds of technology. So it depends on the client. If you want to use an Oracle engineered system, then you know that you have to pay.

Otherwise, you'll need to buy more for performance, replications, and the availability of these kinds of things. But you don't want to pay a lot. You have another option that Oracle support calls Oracle ODA. With ODA, you don't have to use machines, but you have the same kind of features and key performances. However, you may have reduced options for scalability with these kinds of Oracle solutions compared to the engineering system like Exadata. After buying these, you have the support that you need to maintain all these environments. This is what I want to address.

I will mention security. I know that there is a feature for security, but it is not included in the first purchase of this solution. That means if you need to increase the security, you need to buy the security feature which doesn't come by default on these solutions. As you may know, there are a lot of security problems all over the world with this kind of environment. Based on the fact that we are serving the government, we need to have security issues solved from the beginning and take care of security immediately. It would be better if Oracle could have some solutions that would bring us the confidence with their security at the outset. That's one thing I would like to address.

I'm not saying that there is no security on this machine. There is good security on the version of Oracle which is running on these machines, it's very nice. But I'm saying this because I know that Oracle can do more than that and bring the substation to the clients.

For how long have I used the solution?

I have been using Oracle Exadata since 2010.

What do I think about the stability of the solution?

Even with the old machines, we didn't have any constraints with the stability. There were some problems regarding the hardware that you must change because they are getting holes and they fail more frequently. When the life cycle goes, it's the end. But on the other side, this machine is very stable.

Since we have had these machines in production, we haven't had any downtime. Over the last two years, we had a lot of downtime with the old machines because they were very old and did not have enough performance to solve the demands of the database. But we don't have any constraints about the stability with these new machines.

What do I think about the scalability of the solution?

The strategy of the company was not to pay a lot, because we don't have much money. So we began with the scalability approach. We bought enough resources to sustain the demands of all our clients.

If the demands increase, we can also increase the resources and close off the cabinets. We can scale this machine anytime that we need. We can go until the version that they allowed for scalability. Then, if you need to maintain this technology, you can scale out and have two machines working together side by side.

This is a database machine. We have a system that hosts more than 20,000 citizens. So most of the time we have more than 3,000 transactions per day. As a service company for the government, every database resource is on this machine. We have at least three or four databases running on this machine and we have many applications that are running through this machine as well, so it serves all the countries.

How are customer service and technical support?

The first line of maintenance is done by my team, including day to day operation. Support from Oracle is for things which are beyond our knowledge of database administration. Most of the time, the maintenance is done by us. But there is a point you must understand regarding the hardware maintenance. We are not allowed to do hardware maintenance, this belongs exclusively to the Oracle Team. The Oracle Team must be the one that does the hardware maintenance on these machines. Of course, we have a partner here in Mozambique who represents Oracle. This company is the one that is the second line of support. If they find something, they can escalate it to Oracle or they can solve it themselves.

Which solution did I use previously and why did I switch?

When we started the company, we thought about the responsibilities that the company would have attending to all the requests from the government and that we would need to go to robot technology. We thought in 2002 to go directly to work with the Oracle database. So Oracle database was the first database technology we decided to use as our strategic plan for the stability of the company.

At that time, we start working with the small machines and after two or three years, we realized that there are a lot of scalability problems with those kinds of machines and stability issues with this kind of hardware. So that's why we we had lots of downtime and we spent lots of time correcting these kinds of problems instead of thinking about growing the business. So we moved these small machines to a bigger one in 2010. That's all extra data with the X-2 version, but these kinds of machines are getting old and they are out of order now. We cannot buy the spare parts or anything else we need. So we decided to keep using all of the technology, but moved from that environment to a new machine with a better performance.

This has seen better performance. That's why we are still working with only one technology, Oracle.

How was the initial setup?

For Oracle Exadata, there are two main profiles that you have to take care of. One is the installation itself, like assembling the machines, which need some kind of expertise. The other is the installation of the software and creating the database, which need other kinds of equipment. From our perspective, our main goal within all of this is not about these two profiles. It's about the database engineering. Because we are coming from using an old machine, which is running an old version of Oracle, you will need to properly create not only the environment to host the database, you will also need to migrate from an old version of Oracle, like 11g, to 19c. This is another challenge that we have during implementation of these projects.

I can say that from acquisition it took at least, but not more than, five months to implement.

At acquisition we need to design the tenders and the rules of the company. The tender goes out, then it is published, then we evaluate all the tenders, then someone must win the tender. All this takes a lot of times. Then you go to the implementation phase. We did a workshop to design the solution. It took at least three weeks. Then it starts implementing the infrastructure. Migrating the database is another point because one database can take at least two days. That's the situation. But start to finish takes five months.

What about the implementation team?

We did the assembling and installing of all these with the support of Oracle ACS, which is a very nice team that gives personal support for us. It was very good working with them. The other thing is the migrating itself. Migrating depends on each company because not all the companies have the same database architecture or the same data. That's why at the migration stage, 60% of the intervention of migrating from the old version of Oracle to the new version was done by my team. But the Oracle STS support was with us the whole time.

What other advice do I have?

I would of course recommend Oracle Exadata to other people who are looking into implementing such solutions. They need to know what happens with this solution, what can be done with it, because as the government we cannot give out that information because it's not allowed. But, I would recommend it if a company wants to use these solutions, wants to have stability with their equipment, with their applications, and with their systems. If a company wants to be competitive in the market and have a good name, reputation and everything else, I think using Oracle, with the Oracle Exadata machine, is the best way to achieve that.

On a scale of one to ten, I can give Oracle Exadata a 9.

Which deployment model are you using for this solution?

Exadata can significantly improve performance but there's a learning curve in a few key areas.

What is our primary use case?

Primarily OLTP but report is done against a combination of Materialized Views and transactional tables.

How has it helped my organization?

We have a number of statistics collected before cutover on our legacy environment compared to Exadata. Without doing anything other than copying the data across, we saw significant performance gains for most key processes. We receive feedback from users stating how fast the performance is compared to other systems. Performance issues are few and far between. Our database environment is extremely stable compared to the legacy DB configuration. We upgraded from a X2-2 quarter rack to a X5-2 eighth rack and experienced significant performance gains. We recently performed another technology refresh to a X7-2 so obviously, we've been very pleased with the initial investment. For this deployment, we decided to virtualize the Exadata configuration, providing some additional flexibility to our operational environment.

What is most valuable?

We primarily run OLTP with some reporting. With that being said, the feature that provides us the most performance gains is the Smart Flash Cache for the OLTP databases. The "offloading" capabilities provide the biggest performance gains for Reporting such as smart scans and storage indexes. There is a new security feature which allows disabling ssh to the storage servers which will make my security folks very happy. Also, there is a STIG script for hardening storage servers and Database Nodes which can be implemented as a report only or actually implement security settings. Would advise running report first to assess the results and then manually modify, as needed.

What needs improvement?

My biggest gripe has been patches which has dramatically improved since our initial Exadata was delivered (January 2011). The only issues we periodically experience are with non-default RPMs on the database nodes. These may fail during the pre-req check which means opening a SR with support. This has become the exception, not the norm so overall not much to complain about. The X2-2 used to experience frequent disk failures but now, that is a thing of the past. 

For how long have I used the solution?

Nine years

What do I think about the stability of the solution?

There is redundancy built throughout the Exadata so even when we've experienced a disk failure, it's a very low stress situation. Early on we had some performance issues with DBFS and a node eviction problem. DBFS was resolved through a combination of settings changes and a quarterly patch. The node eviction was resolved through a one-off patch that eventually got rolled into a quarterly patch. I would chalk up these issues to being early adopters. We do have an occasional bug but I can't think of any that would be unique to Exadata with the database software. At least this provides some degree of comfort that Exadata is not the source of the issue.

What do I think about the scalability of the solution?

The key for scalability is selecting the appropriate disk configuration and the proper size rack configuration. The two options are High Capacity and High Performance. If ever in doubt, always go with High Capacity. The performance difference is negligible at best, however having the extra space allows for more consolidation. That's the entire point of Exadata, to consolidate databases. We've added a few databases to the Exadata since we originally started to use the environment and there has been no performance impact. In our case, a Quarter rack was appropriate but for larger environments, this may not be enough.

How are customer service and technical support?

Customer Service:

In terms of overall Oracle customer service, we've had good experiences on this front. Oracle has provided us access to their experts and continually check to see how things are going. Whenever an issue comes up, they treat the problem seriously. Since we support a government customer, Oracle is extra motivated to ensuring we have a successful experience. Since 2011, there have been significant improvements with support. Occasionally we do hit issues which it seemingly takes support a longer period of time to provide a patch or workaround but these namely involve additional features, not core technology so it's a matter of exhibiting patience.

Technical Support:

On the hardware side, customer service is quite good. Any disk failures get replaced in a day and with triple redundancy for disk, it's not been a concern. Software customer service has improved over the years. Early on was a little rough as I will say the software wasn't fully mature. As the product has matured, so has the software support's capability to resolve issues more quickly. We can't take advantage of ASR, however this seems like a major improvement for customer service in terms of responsiveness.

Which solution did I use previously and why did I switch?

We didn't switch, we were doing a technology refresh and went with Exadata instead of building out our own Oracle RAC configuration. We previously had a combination of Dell servers, Red Had Linux OS, Oracle Cluster File System on EMC Storage with Juniper switches. This configuration had lots of performance issues, node evictions, and constant headaches. Since moving to Exadata, all those pain points went away.

How was the initial setup?

There is a definite learning curve initially. We had to learn about migration options, shared mount point options, how to integrate with Cloud Control, patching, health check, how to optimize, and how to harden the Exadata environment. Since we went live, many more folks use Exadata so there's more how to's and best practice documents available so the learning curve isn't nearly as steep. We learned a lot in the process and now have a tremendous amount of expertise in setting up, configuring, optimizing and maintaining the Exadata.

What about the implementation team?

We implement Exadata in-house and have gone through several migration methodologies.

What's my experience with pricing, setup cost, and licensing?

We had ACS perform the initial Startup Pack, however there are companies that can do this much cheaper to lower the original setup cost, such as ours. Day-to-day cost is greatly reduced compared to our legacy environment as we no longer have to serve as "fire fighters." In terms of pricing, Exadata is probably not going to be the lowest cost option. There is a price to pay for performance and stability. With that being said, I have not heard of any customers who have regretted the purchase and/or looking to get off the technology. On the contrary, I can't imagine going to another solution at this point and trying to justify this with the user community in terms of why the system performance degraded. Can't imagine that would go over too well.

Which other solutions did I evaluate?

We had a custom solution and evaluated Exadata versus the custom solution. Exadata was actually a cheaper solution due to the number of cores. Oracle software licenses are based on processor so if comparing a Quarter Rack versus a 4+ four node custom solution, Exadata may win out from this perspective. We were looking at a 5 node RAC which would have doubled the cost of our software licenses when compared to the equivalent with a Quarter rack of Exadata. Besides, the performance metrics indicated Exadata would easily outperform the custom solution which made our decision a no brainer.

What other advice do I have?

Exadata is a powerful solution. As I mentioned there is a learning curve. Working with a company that has experience with Exadata can help avoid potential pain points and maximize the ROI.

Stable with good data replication but is very difficult to set up

Pros and Cons

  • "The data replication is very good."
  • "The initial setup process is very difficult and extremely complex."

What is our primary use case?

We are a telecommunications company. The information that we have there, it's Oracle Suite including a CRM, help service integration, and more. That's the core of the system. All the information is available to users using Oracle BI, and some other tools. We're very Oracle-based in our product choice.

How has it helped my organization?

In the past, all the reports that the organization needed would have to pass through a new requirement. And in order to create it, a person needed IT, and the developers. They would have to then test it and release it. Now, since we have this information available, access depends on the role, and the security filters and the user can access information and can make their own dashboards and reports and take decisions. They no longer need to go through IT and developers.

What is most valuable?

We're working on making our usage to be part of a service in a manner that the client can use the information and create their own dashboards, and reports. The client can access the information they need based on the role they have. It prevents them from being dependant on an IT department for access.

The data replication is very good.

The solution offers a good data warehouse.

The solution allows us to avoid conflict with the transactional databases. 

What needs improvement?

The replication of the database needs to avoid collision with the transactional databases. That's a very, very important aspect that needs to be looked at. 

It would be nice if we had access via mobile devices. To be able to have this information and the dashboards on cellphones or tablets or something like that would be great. It would make the solution similar to Tableau, for example, and other kinds of solutions. 

The initial setup process is very difficult and extremely complex.

For how long have I used the solution?

I've used the solution since about 2017. It's been a few years at this point.

What do I think about the stability of the solution?

It's a pretty good solution, however, there may be more opportunity for more stability within the product. That said, the hardware and the database are some of the best Oracle has. It's pretty stable.

What do I think about the scalability of the solution?

The on-premises versions of the solution are very difficult to work with, however, the next-generation cloud-based options are likely easier to expand as necessary.

We have about 800 concurrent users on the solution at any given time. It's a mid-sized company.

I'm not sure if we have plans to expand out own usage. It's a difficult time in Mexico, politically and also with COVID. We had plans to change some things last year, and they have since been pushed out. We're looking at different aspects of our entire system and we're reconsidering how it operates and if we should add partners or not.

How are customer service and technical support?

While we used Oracle consultants for the implementation of the product, and that did not go very well at all, now that it is set up, I can say that we do find their general technical support quite good. We're on good terms with support in general, which comes from America, and I would say we are satisfied with the level of service Oracle provides.

Which solution did I use previously and why did I switch?

We used a different solution a long, long time ago. It may have been something like InfoWorks. However, as I said, it was quite some time in the past.

How was the initial setup?

The initial setup is not straightforward at all. It's very complex and extremely difficult.

It's not easy to explain the entire process overall as there's a lot of criteria. We start working on the requirements, and the first implementation was not exactly what we spec'd it for. We had to start over, and we were complimenting these requirements. However, the functionality and scope ended up not being agreed upon by two partners. The users also did not take into account that they needed to be a part of the process. There were just so many moving parts that never lined up properly.

We've realized that a good solution must also be easy to use as the users will end up being the ones accessing the information, and, if they are confused, they'll never use the technology. On top of that, the requirements and scope need to be clear upfront.

I'm not sure how much staff has been needed for deployment and maintenance.

What about the implementation team?

We used Oracle consultants and our experience with them was very, very bad.

What's my experience with pricing, setup cost, and licensing?

I don't handle the licensing or billing, therefore, I'm not familiar with the direct costs of using this solution.

Which other solutions did I evaluate?

We did look at SAP before ultimately choosing Oracle. We may have looked at others, however, it was a long time ago. I'm not even sure if the same companies exist.

Ultimately, we chose Oracle as it was more suited for telecommunications whereas SAP was more into manufacturing.

What other advice do I have?

We don't have a business relationship with the company. We are just users.

I'm not sure which version of the solution we're currently using.

While telecommunications is an area that always does pretty well - as people need internet and other related services, even in these strange times, it's a strange time in Mexico for a variety of reasons and therefore we are rethinking how we are approaching entire systems and maybe holding off on some decisions until the landscape clears a bit.

While I like Oracle as a solution, and its hardware and database are quite good, when we're talking about implementation, scalability, and integration, I would not recommend this solution. The best option today for a telecom company is likely Salesforce Vlocity.

I would rate the solution six out of ten.

Making the most of contextual database performance is what this solution is built to do

Pros and Cons

  • "This product can noticeably enhance performance of contextual Oracle databases."
  • "It is difficult to evaluate return-on-investment because of the way billing is handled for the product. This should be improved by oracle."

What is our primary use case?

The primary use case is for maintaining contextual databases. In other words, it is for our online applications and services.  

What is most valuable?

The most valuable part of the product is performance enhancement.  

What needs improvement?

We still have to migrate to the latest version of Exadata, which we plan to do later this year or in the next year. Because of that, I am not sure we have anything that we would need to have added. I would need to consult our DBAs after we have migrated. They might find some issue that they would like addressed. But off the top of my head and because we are not on the newest version, it is not right to say the product needs something when it might already be there or has been updated.  

Exadata is practically a perfect solution for us as it stands. Because we are pretty satisfied with it, we have not rushed into the upgrade. I am not sure that we are fully utilizing the options that are currently on the table. For our contextual databases, it is the best option and we do not have any really an issue with it that needs improvement.  

We also need the product for other purposes. For analytics, we use Identity Two and we also need Microsoft Escrow Server for certain tasks. We accept some minor issues that I could identify if I discuss that with our DBAs. I do not think anything bothers us that much that we would need improvements. Of course, the price is the price, so it could always be less expensive. Maybe there are other considerations from the marketing side, but I do not deal with that.  

There are some issues with accounting where we really can not calculate return-on-investment. Exadata pays some fees for you so there is simplified billing, but that separates us from some evaluation of usage. Maybe Oracle could offer a solution for resolving that. Maybe a calculator or separate report that could help customers to find this data somehow. More clarity on this usage might affect how you estimate the workload of the storage and could really make clear what you get in return on using the product for the month.  

For how long have I used the solution?

We migrated from Identity two on to Exadata sometime between five and six years ago.  

What do I think about the stability of the solution?

It is stable like other Oracle products.  

What do I think about the scalability of the solution?

It is scalable. 

Which solution did I use previously and why did I switch?

We developed some software for migration. The previous database was on the mainframe server and it was quite a nice product. We have a lot of experience, both with Oracle Exadata, with other databases, and other systems that we also use. We work with many solutions and we use what we think is best for a particular task. Contextual databases work especially well with Exadata.   

What was our ROI?

It is not really clear how to calculate the ROI for Exadata. Because you need to do the calculations for yourself, you need to know the license modeling pretty well. Even then, it is not very clear how much it costs for Exadata performance, CPU, and other additions. You really can not calculate these points when Exadata pays for you. Oracle could help customers to find out the actual numbers and help with calculations for ROI.  

What's my experience with pricing, setup cost, and licensing?

If you compare an Oracle database on your system to buying into Exadata, which is an engineering system consisting of hardware, then, of course, it is more expensive. On the other hand, it gives you some possibilities to experience better performance than you would have if you would run Oracle on your servers. When you scale it up, it means that you actually get this additional hardware for free. You need to pay more for the license instead. This is one of the cost differences that is not very clear how to calculate. It is hard to tell how long it takes for one product or the other to become a cost advantage.  

There are some extra costs for hardware and for everything else if you upgrade to have better performance. At that point, the system uses not just the standard license, but also the storage shares. This can be quite significant when doing larger implementations. So the clarity of the cost models is something that could probably use some improvement from the Oracle side.  

Which other solutions did I evaluate?

It is quite difficult really to compare and evaluate all the solutions available. The market is pretty mature. We have to just make a shortlist of possible solutions from whatever products and solutions we are looking at and go from there. It is not realistic to do an in-depth analysis of everything.  

A lot of solutions that are more oriented toward network monitoring are now rebranded. The markets itself was previously called anomaly detection systems. Sometimes it is not quite clear which of the solutions really have additional capabilities that can make a difference without really studying them in-depth. We obviously looked at some extra products to contemplate and compare, and we continue to. But, for now, what we see and what we decided is where we will be staying. I am not sure that any product really offers a significant upgrade that is worth migrating for.  

Darktrace is a step ahead in some ways but, in this area, it is really difficult to assess clearly because there is a lot of the marketing fog. It is sometimes quite difficult to get to the facts about the advantages. It also may not be worth migrating when the product you are using will develop the same or similar capabilities.  

What other advice do I have?

On a scale from one to ten where one is the worst and ten is the best, I would rate Oracle Exadata highly. If you compare it to other engineering databases, I would rate it a nine.  

Practically perfect from my point-of-view.

Excellent storage cell capabilities and intelligence with great speed

Pros and Cons

  • "We can use virtualization on Exadata."
  • "The improvement could be made on the hardware level as the habit in the industry is to go better and faster and larger with every iteration."

What is most valuable?

The separation between the database nodes and storage cells is the key feature of Exadata. The capabilities of the storage cells, the intelligence, are excellent. 

The speed is unbeatable. 

Exadata was mostly for data warehouses. However, in time with a model of powerful processors in database nodes, it's also an OLTP machine. It's very good. The latest versions offer even more performance, as they have a persistent memory and a lot of features.

The usage of the internal InfiniBand Switches is a key feature in Exadata. Everything is fast due to this separation at the database level and storage level. It's intelligently designed and has a very fast connection between all of the components of Exadata. 

We can use virtualization on Exadata. We can choose capacity on demand. There are a lot of new features that have turned up in the past two to four years. The solution is growing and becoming broader in its scope.

What needs improvement?

The improvement could be made on the hardware level as the habit in the industry is to go better and faster and larger with every iteration.

From the software point of view, management point of view, it's okay right now. However, I don't understand why Exadata has no database nodes with SPARC processors. Oracle has SPARC servers that are on RISC processors and are more powerful processors than Intel processors. They never do Exadata with such processors on the database nodes level. However, they tested and it wasn't very useful. I would like to see Exadata with RISC processors on the database nodes if it's possible.

For how long have I used the solution?

I've been working with the solution since 2012. It's been about nine years - almost a decade. It's been a while.

What do I think about the scalability of the solution?

You can scale the solution. You can configure it how you like and buy more cells or nodes to add to it. 

How are customer service and technical support?

The technical support has been okay. We've been satisfied with the level of service.

How was the initial setup?

The initial setup isn't too complex. However, in the present, the initial setup of Exadata isn't made by Oracle partners or the client. There is an advanced ACS department, Oracle Advanced Customer Support, that handles the implementation. In this team, there are very good specialists on Exadata. These specialists from the ACS department are the guys who will install Exadata for the first time for the client. 

It's not something very complex and something which cannot be done by others, however. Our team, for example, was installing Exadata. It's possible to be done by other teams with, of course, the appropriate competencies. The implementation sits somewhere between simple and complex. The machine is complex. We cannot set up a machine like this with more components and different components like a laptop, for example. 

What about the implementation team?

There is a specialized team that handles the implementation for the client.

What's my experience with pricing, setup cost, and licensing?

I don't evaluate the fees involved in using the solution. It's too big. However, it's my understanding that you need to pay for the hardware, the nodes, and the cells. That said, you can configure it however you want. You can easily buy and increase the capacity in only the nodes or only the cells if you prefer. It's worth the money you spend. The value is there.

Which other solutions did I evaluate?

I've looked at other options. For a data warehouse, it's a better solution. It's better than Teradata, for example, or other complex machines from the competitors. Migrating data warehouses from other infrastructures to Exadata has a good success rate. I wouldn't say that it is the better solution for an OLTP system, however, for an OLAP system, it's a better option.

What other advice do I have?

We've been Oracle partners for around ten years or so. I'm a project manager, and not overly technical. 

We don't have Exadata in our company, however, we have Exadata via a client. The current company where I work is the first company in Romania to sell Exadata in Romania. There are a number of Exadata solutions sold in Romania - which is why my colleague has achieved past competencies and certification in Exadata machines. They are very good, and they are delivering the present services on Exadata. I manage the projects where they deliver services on Exadata only for the customer, not in our company.

I'd advise users to consider the solution. You pay more money on the machine, however, you pay less for the licenses. On top of that, you have enough room to put a lot of data there. You can virtualize some machines and you put items on the application level, however, I don't recommend this. 

If you already have separate machines, and you have licenses for all these machines and you want to put new hardware in place, it's better to put Exadata in place instead of a lot of other machines. That way, you can consolidate the database here and you will pay less on database software licenses.

I'd rate the solution at a ten out of ten. I've been very satisfied with the product overall.

We can run the exact same software as the latest x8-2 Exadatas and we can even install virtualization if we want to.

Pros and Cons

  • "Our machine is used for our internal development of Oracle-based solutions, PoC benchmarking, and training/familiarization."
  • "We would like an option of a hardware-only support solution, but Oracle currently does not provide this."

What is our primary use case?

Database Consolidation and Performance is best on this platform. It is tailor made to run the oracle database and hence the defaults on this device force you to choose oracle best practices. No more moaning by your storage admin that he wants to carve out the luns ,that he doesn't understand ASM stripe and Mirror Everything S.A.M.E  and that he knows better what's good for the oracle database.Even the old x 2-2 can run version 18c of the database.

How has it helped my organization?

Ability to patch with no downtime and the ability to  ensure all the prerequisites are satisfied without manual intervention saves time and effort and makes systems we deploy for our clients more secure. Licensing costs too are less for Oracle linux and for clients moving to the oracle cloud it is included in the price of the subscription. with the new Exadata cloud @customer offering there are even more ways to get the benefits of Exadata without lareg capital expenditure.

What is most valuable?

Ksplice, Prevalidated Oracle RPMS , the testing done with Oracle database and weblogic and the UEK kernel have made Oracle linux systems best for running large oracle databases and other packaged applications.Exadata's IORM and DBRM make it a great consolidation platform. its smartscan feature and flash cache are unparallelled in providing performance.

The new exadata x8-2m has even higher speed roce 100GBps connectivity.

What needs improvement?

we do have a little trepidation with systemd as it does have a learning curve . Also changing to a binary logging format for us feels like retrograde motion , but sadly almost all linux varients have moved in this direction.

For how long have I used the solution?

Over nine years across multiple versions.

What do I think about the stability of the solution?

We have encountered several predictive disk failures, but we never lost data because the machine detected the issue before the actual failure and alerted us and Oracle to dispatch a spare through ASR.

What do I think about the scalability of the solution?

No issues at all except when the code we were working with was not scalable (procedural PL/SQL and cursors). In fact, the RAC worked very well and we saw near-linear scale-up, and the license costs were dramatically less than a conventional solution.

How are customer service and technical support?

Customer Service:

We have had great customer service. We had almost no issues with the machine as such except for some predictive hard disk failures and the machine never had a problem due to the redundancy, so there was zero downtime for any of the hard disk faults.

Technical Support:

Majority of the cases we have had good support. We had a few small hiccups with ASR Auto Update as it twice lost configuration. However, we have since disabled that function and do the ASR updating manually after taking a backup. As this feature is not essential to the actual running of the machine, it never caused us any major issue.

Which solution did I use previously and why did I switch?

The initial setup was pretty straightforward. We had undergone training so we knew what was required and hence there were no surprises. There was participation from the vendor team also.

How was the initial setup?

It was a vendor team who did the bare bones setup and then we did the actual deployment and migrations in-house. Our team is very seasoned. The vendor team was quite good and we had no issues with installation and initial configuration.

What about the implementation team?

As we have the capability and specialization to do the software implementation in house we worked collaboratively with the vendor team for the same. Vendor team was very knowledgeable.

What was our ROI?

We have realized a lot of tangible and intangible benefits from the machine. It would be difficult to put a dollar figure to it because the machine allows for things that simply cannot be done without it. So in that way, we can safely say that the machine paid for itself within the first 12 months.

What's my experience with pricing, setup cost, and licensing?

There are many new options available now, including IaaS and CoD. I would advise others to engage a third-party expert to ensure that they get the best deal. I did note that Oracle does tend to internally oversize things especially if they want to fill up a budget, and hence third-party oversight is essential.

Which other solutions did I evaluate?

For us, we work with all vendors and every vendor has its good and bad qualities. We use all solutions and hence we know when to recommend the Exadata machine.

What other advice do I have?

I would always consider this solution when I want an integrated scalable best-of-breed solution for enterprise class Oracle database deployment. I have seen so much inter-vendor finger-pointing during SevOne outages to ever want to wander back into that uncharted wilderness.

Which deployment model are you using for this solution?

On-premises

Enables us to run with more performance cores with less CPU to attend all the database demands

Pros and Cons

  • "It has improved the performance, now we run with more performance cores with less CPU to attend all the database demands. Reducing Time to Market, increase our ability to face the competition with speed and low cost."
  • "I believe Oracle must improve its procedure to support the clients. The customer Ready Service must provide more use cases and benchmarks of their infrastructure to support client design decisions. Oracle must audit their partners regularly to guarantee they provide quality service even after been passed on partnership examination."

What is our primary use case?

I was running an ERP system on Rackmount machines with critical databases on it. There is no way to scale-in and very expensive to scale-out as the system is growing countrywide. Replication between sites and branches not guaranteed. Also, the EOL of this infrastructure drives this huge change, and to avoid huge change management on the application point of view and the need to maintain the same database technology it was the biggest challenge that I ever faced during this times, moving from Version 9 to 11g and now to 19c.

How has it helped my organization?

It has improved the performance, now we run with more performance cores with less CPU to attend all the database demands. Reducing Time to Market, increase our ability to face the competition with speed and low cost. We improved the database availability while ensuring business continuity implementing efficient replication between main and DR site, so we decreased from one downtime in two months to zero downtime a year. So we can sleep as we are confident that data replication is running without any constraints. Multi-tenancy is one feature that can be used to guarantee the investment on this infra.

What is most valuable?

Business Continuity is the most valuable feature. The replication between the site via Data Guard is performing without any constraints, the agility to make tests of switchover, and back following disaster recovery procedure. The performance using this machine to providing database service is as easy as next to next database administrations. We can run AWR data collection for performance evaluation and problem-solving without any production performance constraints. Using Database partitioning and Cache Memory in each storage cell boost all we need as a database machine. The easy administration gives us time for training, improve our business understanding, and care about our competitors. Also, the container Database (CDB/PDB) together with other technologies (like Micro Services) can very improve the company core business.

What needs improvement?

The Oracle Support. I believe Oracle must improve its procedure to support the clients. The customer Ready Service must provide more use cases and benchmarks of their infrastructure to support client design decisions. Oracle must audit their partners regularly to guarantee they provide quality service even after been passed on partnership examination. Increase the FDP in the Southern Africa region can boost quality and competition on support service also increase product selling on these countries.

For how long have I used the solution?

I have been using Oracle Exadata for bout nine years.

What do I think about the stability of the solution?

This machine are equipped with new edge of fault tolerance technologies ensuring business continuity. All servers have dual power supply and the hard drives are reliable. Following the Oracle procedure to assembly this hardware in your datacenter with clean power is one thing that guarantees the stability. Of course, a support contract must be signed off between client and oracle to predict all possible disruption on time.

What do I think about the scalability of the solution?

There are many models of this engineering system, starting from X2 in 2011 to the last version X8M, you can choose a quarter, half and full, depending on your workload and budget. Starting with the quarter size you can scale it by adding more servers and storage until Full version or adding another box.

How are customer service and technical support?

Every implementation is unique. I have been working with Oracle since 2005 and have not had issues regarding technical support. But Oracle must audit their implementation partners regularly to avoid major problems like a bad quality implementation that make clients raise a call.

How was the initial setup?

The initial setup is not so complex as it is done by Oracle Experts and is validated by the senior engineers.

What about the implementation team?

We implemented it through the vendor team. I worked with a very skilled personal, like project managers, ACS Support Leaders and technicians that have very experience in deploying this kind of systems

What was our ROI?

Using this infrastructure for a database as a service or Oracle Cloud at Customer/Service can be a good approx. to increase your ROI.

What's my experience with pricing, setup cost, and licensing?

Going to EXADATA is not good advice for non-profit companies, like government institutions, all though this is a very safe infrastructure to guarantee security and availability for a long period. The OPEX must be well prepared for a period that can have all the return of the investment. Using EXADATA as a database as a Service (Multi-tenancy) can be an alternative to good ROI.

Offers a huge choice of options for the enterprise, whether on-prem or cloud

Pros and Cons

  • "Regarding features, there are so many that we can offer to customers. When we sell Exadata Cloud, there are many options to choose from, especially when it comes to enterprise database options. In my experience, the main features that are appreciated are various ones like GPS and the assortment of security options."
  • "There is one aspect to Exadata that I dislike, and that's the inconsistency with other databases. When you try to get Exadata to function with another type of database like SQL, or others, there should be reliable and consistent operation. When this is improved on, we should start to see more applications growing the market."

What is our primary use case?

We sell hyper-converged infrastructure tools including Oracle Exadata to enterprise customers such as governments. These are large projects that handle big data and typically run into the range of several million dollars, and in 2016, we had our first big Exadata project which involved implementing two superclusters with Exadata and Exalogic together. 

In some processes, we use converged infrastructure tools, but it's far more common nowadays to go with hyper-converged infrastructure tools. On our side, we prefer hyper-converged infrastructure because there just aren't that many people using the standard convergence model anymore. We're changing our processes to work exclusively with hyper-convergence and other technologies that complement hyper-convergence.

We use Exadata and Exadata Cloud at customer sites, and the main project that we're involved in now is hyper-converged Oracle environments with Exadata. I'm studying how to best apply the hyper-convergence model in Oracle to change Exadata to VxRail. But my forecast going forward is that we will be using fifty percent hyper-converged tools with Dell VxRail, and fifty percent with Oracle Exadata.

How has it helped my organization?

With Oracle Exadata, the change from on-premise to cloud is becoming a reality. With this, it becomes better and easier for us to make renovations and maintain our projects. We earn money with renovations on cloud, but when it comes to on-prem, we don't earn much when the customer needs renovations and support.

What is most valuable?

Regarding features, there are so many that we can offer to customers. When we sell Exadata Cloud, there are many options to choose from, especially when it comes to enterprise database options. In my experience, the main features that are appreciated are various ones like GPS and the assortment of security options.

What needs improvement?

There is one aspect to Exadata that I dislike, and that's the inconsistency with other databases. When you try to get Exadata to function with another type of database like SQL, or others, there should be reliable and consistent operation. When this is improved on, we should start to see more applications growing the market.

For how long have I used the solution?

I have been using Oracle Exadata for six years, more or less.

What do I think about the stability of the solution?

Stability is very good. Especially if you maintain it and always update, you won't have any problems with stability. Once Exadata is established, it's 100%.

My one customer was using the Exadata version from 2013 which was extremely outdated, and when they changed to the updated version of the main system application it was very healthy for the customer's company. 

What do I think about the scalability of the solution?

I think the scalability is good, but it can be even better. With the newer editions of Exadata, they are changing some features to meet the needs of growth and scalability, like access to additional disks in the storage environment, and they've upped the memory, too. But I don't think it was central, or essential, to the Exadata offering at first.

How was the initial setup?

Nowadays, it's easier. In the first years of implementation of Exadata it was a bit more difficult, but now it's easier. If you have a team that knows Exadata well, and knows the limits of Exadata, then the setup and implementation is easy. If, on the other hand, you don't have an experienced team, then it's really difficult.

What about the implementation team?

The last implementation we deployed took about two weeks, more or less.

What's my experience with pricing, setup cost, and licensing?

The majority of our customers are in government or big enterprises, and the projects that we sell come out to several million USD. With this amount of money on the table, it's always better to have an experienced team of consultants, who know Exadata very well, handle the implementation.

What other advice do I have?

If you're interested in going with Exadata, then I highly recommend looking for an experienced consulting firm that has completed at least one large implementation before, because it isn't something you want to put in the hands of unskilled consultants. And don't forget to be careful with your implementation when it comes to GDPR in Europe.

I would rate Oracle Exadata a nine out of ten.
