Oracle Enterprise Manager Reviews

• Enterprise Manager 12c comes with an out-of-box self-service application that lets end-users deploy a wide range of these services. End users can choose to manage and monitor all applications along with databases and platforms/OS, all in an on-demand fashion. For each request, they can specify the amount of underlying resources (CPU, memory, etc.) that they require for each component. • Enterprise Manager automatically provisions the requested service and the appropriate resources. The self-service application also lets users define policies to scale out or scale back resources based on schedule or performance metrics. For example, one can set a policy to elastically scale out a web server if the processor load on existing web servers exceeds a certain threshold value. • It allows management of sophisticated Oracle applications, like Oracle E-Business, Siebel, and PeopleSoft, aiding in many administrative activities of these apps, like real user monitoring of any web application.• Enterprise Manager 12c has the ability to define contractual Service Level Agreements (SLAs) that govern the contract between the application owner and the provider of the Cloud. Administrators, as well as users, can also define management policies that automatically adjust the service resources, to ensure that SLAs are met.• Enterprise Manager enables the application for the end-user via a self-service interface, both in graphical (GUI) .

The only con is that we may need to install patches provided by Oracle from time to time for its upgrades or bug fixes. This is an activity that occurs quite frequently.

Oracle Enterprise Manager 12c, is a transformational technology that comes with a set of comprehensive features and great practices, that help IT transform into a true enterprise Cloud that delivers on business needs. It offers a single integrated console for testing, deploying, operating, monitoring, diagnosing, and troubleshooting, today’s complex and wide IT environments. It offers a simple scalable solution for running Oracle applications. It enables you to manage everything in your datacenter, from the hypervisor to the operating system, database, and application tier. I have used this technology for quite a long time and found that Oracle Enterprise Manager is the industry’s first solution that has the ability model, not only infrastructure as- a-service (IaaS), but also platform-as-a-service and database-as-a-service Clouds, from a single console. The extent of usage of Oracle Enterprise Manager depends upon nature & the size of the organization and management’s concerns. However, Oracle Enterprise Manager provides a full board of controlling & monitoring as per your needs.

We primarily using this for the monitoring, it monitors all our Oracle infrastructure. As a DBA I also use it for SQL monitoring and for performance tuning analysis.

It's user friendly.

We have Oracle Accelerator. We heard this is a better tool for monitoring Accelerator. But it's more than monitoring just that, we have extended the monitoring to DB2 and SQL Server platforms.

I think they have already listed some things in 13c. I heard it includes a couple of features we are looking for like monitoring templates. I want to explore those features. Probably they will be included in 13c.

We have been using it for the last three years.

It is pretty stable. There are some pros and cons, but we compared it to other tools which are available for monitoring Oracle databases and other products, and what we found is this is one of the best.

It's scalable. Currently, we are monitoring close to 3000 targets and it's pretty well scalable.

I'm a bit skeptical of it. I personally experienced a little longer time than I would like to get the right solution for issues. They have good support. It depends on the person with whom you are interacting.

I would say setup is moderate, actually. It's not that difficult. If you have a good background in web logic and servers then I think it's easy. They have very good documentation in place so you just have to follow the documentation and it can be installed easily.

This is one of the best tools we've had. I would advise others to go for it.

The most valuable feature is that it is web-based. That helps us to get access from any location without being dependent on your personal laptop. You can access it from any laptop, any iPad or even iPhone; kind of everywhere.

Access to the data; you can access it anywhere. That helps us to get the information readily. That improves productivity as well.

Some of the new features it could give us: maybe access to some of the taxation data and also some of the other benefits it could include as part of the system. That would be useful.

My experience with the stability has been very good. I have not seen any issues. I use it for my own purposes, in a limited way, but I haven't come across any instability or not being able to access the data; it being down or anything like that.

We’re using it for around 15,000 employees, and it is meeting our requirements. I’m not sure how much it can go up to, but at least 15-20,000, I have not seen any problem.

I haven’t used technical support.

They wanted something that was available everywhere instead of being available only on a particular laptop or PC. That was one of the reasons for it: easy accessibility.

The first reason we chose Oracle was the feature set; it was really comprehensive. Plus, it met most of our immediate needs. That kind of led us to pick Oracle.

When I’m looking at a vendor like Oracle, the most important factors are stability, scalability, and of course, the price. All three of them definitely help to make a decision.

Initial setup was really simple: just go to the website, register, and you’re good to go.

If you are looking for a solution that is accessible, because of the global nature of the workforce, I think this is a good solution.

From the features perspective, I see there's still more that could be done, as I have mentioned.

I think what I really like in this product is that DBAs and my management development team don’t have to sit and manually write queries.

It has a graphical interface, which makes it handy for you to monitor the databases and that is the most useful feature.

You can manage many databases at the same time.

You don't have to write ad-hoc queries. Initially, my DBAs used to write scripts which were manual. So, running the scripts, writing them and trying to figure out what we want to monitor was a very difficult process. With OEM, you have all of this in the inbuilt interface, which really helped them in adding new databases in the main that we must monitor.

As the number of databases increased, it was fast for us to start monitoring them as well.

One of the big problems we had was using Data Guard along with OEM; it just didn’t work (Data Guard is a local higher level solution). Every time we did a takeover, it would stop working, so that was the biggest challenge we had. I think that this has been probably fixed in Oracle Enterprise Manager Cloud Control 13c.

We had issues in terms of stability. Some of the functionalities, which we were looking for, were not available. It's not that it wasn't working, but it wasn't able to meet all our requirements.

Stability, as far as it was in a test environment, we did find a few issues. This was in Oracle Database 11g and it would just hang our systems. Thus, we didn't let it go to production.

We have Oracle Advanced Customer Support in our company. Using it was easy. It's just that product had a few issues in certain scenarios.

Oracle recommended it to us: "Everybody is using it out there, so use it!"

It was straightforward. We had to install a server on the database side and GUI on the client side; it was quite straightforward.

Based on our experience, if you are looking for a certain type of requirement, it would work.

The main requirement for us was stability since we run machine-critical applications.

Resiliency is really the main requirement from our side, even beyond scalability.

We run a company that provides services for banks and financial institutions, and resiliency is the most important factor, especially for a product like OEM. Security is equally important but for OEM, we don't really expose anything, so it's fine. It's more of a monitoring interface.

Enterprise Manager comes with a suite of products that includes agents for setup. This makes it easier to monitor databases as well as servers and SANs.

It's given us the ability to monitor multiple aspects of the organization. Also, the ability to monitor different versions of Oracle and different platforms has been helpful for our customers.

Using, setting up, and maintaining the agents can be tedious and even almost a full-time job. Once it's done, it works pretty well. It's just setting them up that could use some improvements.

We haven't had any issues with the deployment other than setting up the agents.

I've had problems with its reliability and speed. Sometimes even giving it a large amounts of software and hardware to run on, it can still be sluggish and fail to respond as quickly as you would think.

It does seem to scale. Even when we throw thousands of objects at it, the scalability still seems to be there.

The newer versions are much simpler and they have a better look and feel, and once you get the agents taken care of, it goes a lot quicker.

We implemented it ourselves.

If you are going to be database-heavy, and that is what you are going to be monitoring the most, then Enterprise Manager might be your best bet. If not, there are other options out there to look at to see which pieces you need to monitor. Do we need to monitor applications, servers, and networks? Figure out which part you're going to need for that.

Go for it and utilize all the features!

The most valuable feature is the user-friendly GUI. With OEM, we can see the monitoring tools for the host or database.

We use it every day. For any performance issue, we jump into OEM and then we use it. We monitor the database to help us deal with the issue.

There as some monitoring tools, such as GoldenGate, that would be great if they could put them in OEM.

Right now, whatever we have is enough, but for additional features we want GoldenGate.

We have been using Oracle for a long time.

We do have other technologies.

It's stable.

We are moving to a data center right now. It was in one data center and we are moving it to another data center, where we have our other data business, and it has scaled well.

Technical support is good; very good. They were efficient.

Initial setup and upgrades were straightforward. We have upgraded from 10 to 11 and from 11 to 12.

It's a very flexible, straightforward installation. It's user friendly, usable day by day and we can see the database monitoring, host monitoring, everything.

When I’m looking at a vendor such as Oracle, I look for good tech support, reliability, and stability.

We use Oracle Enterprise Manager primarily for database management, with a focus on performance monitoring. 

Our environments are composed of both standalone and cluster databases which, in turn, are deployed in Oracle appliances like ODA and Exadata, as well as others hardware vendors.

In addition, we use the tool to create, configure and manage high-availability environments using Oracle Data Guard and Real Application Clusters, automation of manual activities and patching.

With Enterprise Manager, we have achieved a dramatic decrease in the number of database incidents. As a result, unplanned downtime has been reduced because we are resolving issues before the business is even aware of them.

The product has powerful features for diagnosis of database issues, complemented with tuning capabilities for most of the issues found.

With ASH Analytics, ADDM, Real-Time SQL Monitoring, SQL Tuning Advisor, we can measure SLAs, detect performance hotspots, perform deep diagnostics into specific tiers, tune applications, and remediate.

Oracle is always making improvements to Oracle Enterprise Manager. I think Enterprise cloud integration presents new management challenges.

More than five years.

We always strive to have the latest version of this product, which has always helped to improve stability and performance.

Yes, we encountered scalability issues. However, there are several techniques for achieving optimal performance. It can also help with capacity planning, sizing, and maximizing overall performance in a large scale environment.

Inadequately-sized Enterprise Manager deployments may result in the overall benefits of Enterprise Manager being compromised.

Good.

The initial setup is pretty straightforward. Today, you can even download the templates found on the Oracle website.

The basic functions are free. You only pay license fees for advanced features.

I’ve been using this product for years. I evaluated other options from different vendors such as Foglight and SolarWinds, to name a couple.

To me this is the best product for enterprise database management. I rate it a 10 out of 10.

Now, before you implement, you can do several tests with the Enterprise Manager templates VMS, available from Oracle. Also, check the compatibility matrix and try to always keep your system up to date.
