What is Oracle Linux?

Oracle Linux and Oracle Virtualization are powerful open source foundation products optimized for building both Private and Public Cloud Infrastructure. They provide a secure, scalable, and flexible platform for running both legacy and next generation Cloud Native Applications. As the foundation for Oracle’s Public and Managed Clouds, customers benefit from the comprehensive co-engineering which ensures a robust and highly manageable platform that is battle-tested in one of the worlds largest public clouds.. Unlike many other commercial Linux distributions, Oracle Linux is easy to download and completely free to use, free to distribute, and free to update. And Oracle Linux Support levels are simple and low cost, featuring Premier lifetime support, access to additional management tools such as Oracle Enterprise Manager, zero-downtime kernel updates using Ksplice, and access to award-winning Oracle support resources and customer support specialists.

Ksplice allows us to apply hot-patching without downtime and avoid scheduling issues across multiple organizations

What is our primary use case?

Fujitsu's Oracle/Intel platform has been specifically designed with Oracle in mind using Oracle VM, Oracle Linux, for our customers wanting to use Oracle product, applications, databases. We've designed it in a way that we get the best possible performance from the applications and databases on our engineered system.

Pros and Cons

  • "With Oracle Linux Ksplice specifically, we have organizations looking for minimum downtime. We're able to apply hot-patching at any time; once we've proven they're tested, ready to go, we don't need to take downtime to apply them."
  • "What we found in moving from Oracle Linux 6 to Oracle Linux 7 was the whole interfacing with the application and the fact that operating had all changed, all the commands had changed. You need to be aware that there is some kind of training, some kind of handover required for your technical guys, understanding different ways of interacting with it. Bear that in mind."

What other advice do I have?

I am the Oracle practice CTO. I work for Fujitsu. We cover all the aspects of IT, for enterprise, for infrastructure, through to applications and managed services. I work for the Business Applications Services, we cover anything around enterprise solutions, enterprise architecture, anything that will aid them in their business process. In my role at Fujitsu I oversee all of the Oracle architects, so any solution owners from infrastructure to applications, and all the bits in between. All architects and solution owners report to me. In the context of, if you're wanting to use the Oracle…

With Ksplice, which is provided free, it can be patched without downtime.

What is our primary use case?

Ksplice is a really cool feature. The availability is maximized because it can be patched without downtime. Oracle Linux provides free Ksplice.

When it comes to important criteria when selecting a vendor, I think experience is there, but they really have to care. They have to own the problems; I think owning your client's problems is the number one thing.

What is our primary use case?

We are a system integrator from Slovenia and we work extensively with OVM and Linux products.

What other advice do I have?

Linux is a 10 out of 10. I would say that it's very affordable, that it's very stable, it has a great community behind it, and it's also very scalable and it performs really, really well. Up-time could be two to three years, which is unbelievable compared to the Windows world, for example.

Open source provides cost savings yet we still get Oracle performance and support

What other advice do I have?

I would say, from my experience, that you need to make sure that all the features you are using are compatible with the OS version, the Oracle version that you are going for. So far, we haven't seen any problems, it is fully certified with Oracle, and all the features are working without any issues, it is very performant. You can go for it as long as all your features are supported with this operating system. We are very happy.

Stable, flexible, easy to work with

What is most valuable?

It's stable, you have flexibility and dynamics, and it's easy to work with.

What do I think about the stability of the solution?

Linux is very stable.

What do I think about the scalability of the solution?

Scales well as well.

How is customer service and technical support?

It works quite well, if there's a problem you can open a ticket and the support works quite well.

How was the initial setup?

It depends on the complexity of the environment, but you can download images and there are all kinds of tools nowadays, so it's quite easy.

What other advice do I have?

I always liked Linux and Unix and Nix operating systems, so I always favor them before anything else. Always recommend them.

I can develop, deploy, and test rapidly; I love the portability, moving it to other versions

What is our primary use case?

My company is based out of Virginia. I do a lot of work with the federal government.

What other advice do I have?

I wish my enterprise would adapt it, so I give it a 10 out of 10 in my book. But I guess we'll have to give it a seven and eight out of 10 from an enterprise level, just because they haven't bought in yet. If you're going to go into the Oracle industry, learn Oracle Linux, learn the ins and outs, and it'll help you out. Like I said, with the whole cloud infrastructure, the whole cloud architecture, I think Oracle Linux is the way to go.

We are able to deploy a valid distribution of Linux; direct support from the vendor is key

What other advice do I have?

For sure, choosing a vendor that has been around a long time is important for us. The relationship with the vendor is important, because if you have to run a business on top of this operating system, you need to be sure; you don't want to have nightmares, because production is first of all. Then, all the other stuff.

Because it's well known, I can leverage the skills in my organization; but needs better bug logging

What other advice do I have?

I would suggest start to get some knowledge on your own, know what it is about. Then, when you approach the expert, you know what to ask. Make a dichotomic approach, the right questions. Basic training is always recommended. I would not go too deep in unnecessary training; do basic training and then start working on it.

If you are running Oracle systems there is no vendor conflict when you need support

What is our primary use case?

We use Oracle Linux with multiple clients for multiple applications.

What other advice do I have?

Regarding criteria when selecting a vendor, if I am working in an Oracle world, I would what's important is being "family." If you are using Oracle as a database, using Oracle Linux is a good choice, because you are in the same family. Support is coming from the same vendor. The chances of vendor conflict - for example, being able to pull in people from different vendors; if I'm using Red Hat Linux I would be pulling people from Red Hat Linux, I would be pulling people from Oracle databases - that kind of scenario would not be there. Support would be seamless. In terms of advice I would say…

Red Hat compatibility allows us to move very easily between platforms, including the cloud

What is our primary use case?

We're quite heavy Linux users. We do high performance computing on Linux so we like a Linux which is compatible with several platforms, so we don't have to cross-compile for too many Linux editions.

What other advice do I have?

In terms of important criteria when selecting a vendor: support, and stability of the product as well. Obviously having the packages certified by Oracle, a known stable platform, makes it easy. We don't have to worry about doing an update and then breaking things. That's probably one of the key things for us. I'd say try it out, it's simple to get running, get it onto a CIN and then just give it a go.

UEK kernel is optimized for Oracle databases; online kernel patches with zero downtime

What other advice do I have?

When selecting a vendor, the cool thing about Oracle Linux is that the customers are going to be running an Oracle database on it. At the same time, if they’re going to be running Oracle databases on top of Oracle Linux, you have one vendor to call for support, you have one vendor to choke at the end of the day if things go wrong. It's a 10 out of 10. You are going to get great support from Oracle Linux. The portal that you would log into for support for Oracle Linux is going to be the same portal that you would log into to get your database support. It will be the same portal that you log…

Paying only the support cost and getting Ksplice are key features for us

What other advice do I have?

I always tell them, if you're running Oracle workloads like database, that's a natural fit for Oracle Linux. Because, like I said, It's pre-configured, you get to validate configuration, you get Spacewalk, support. It's a nice little bundle. When selecting a vendor, the things we focus on are high availability, scalability, and business requirements. All those things come together. We figure out whether it's a RAC solution, OVM solution, virtualize, a middle-tier stack that all fit in together. I would say it's a nine out of 10. Start using it. If you're familiar with Red Hat, you're going to…

It's on the fastest machines on planet Earth, it's more secure and more private

What other advice do I have?

I recommend Oracle Linux regularly because it's a standard that works well with the Oracle Database, it works well with all the different needs. When you look at the topology in a general IT department, it fits very well. In the cloud, Linux runs the cloud. Linux is a 10 out of 10. Windows, not so much; maybe down at two or three, especially on the privacy side and security, in my opinion.

It provides us with templates and Oracle-validated configurations that allows quicker install and configuration of Oracle Database software.

What other advice do I have?

My advice is to act on the pattern: Plan – Do – Check – Act. From the way the question is formulated, the first step is done. They should now download the product, install an in-lab environment along with the related applications, check how the framework responds to the specific needs, and make the Go / No-Go decision. My estimation is that for most cases the Go decision will be taken, but that can depends on specific other elements. Another advice is to have one person providing infrastructure support with at least one Oracle Certification in this area, so easy issues become solved in agile…

The licensing is simpler because customers usually don't have to go to VMware, Microsoft, or any other company to get different things. The functionalities they need are already built-in.

What other advice do I have?

I would probably have them explain, at least to themselves, what they're going to use it for, what applications are going to be running on it. And if it's going to be Database or something more Oracle-based, it's going to be great for that. If it's going to be something else, it may not be the best fit, depending on exactly what they are going to do with it.

If you're running an Oracle database, use Oracle Linux.

My general feeling would be "Don't worry too much." It is not that complicated. It's a very stable Linux distribution, and especially when you're in doubt, you can always reach out to the guys from Oracle. That is, of course, if you chose to pay for it, but you can try this stuff for free. You can spin it off on a VirtualBox image. Just download stuff, just give it a try and you will see how easy it is. That's my general advice.

Rating: It’s a 10, because even though there are free alternatives, I mean totally free alternatives, like CentOS, I've quit using them.

Oracle’s online documentation was very adequate for most troubleshooting, however, I would infer that only after learning the terminology used for the various products. I don’t know if it’s possible to overcome this technically (e.g. better search capability with online documentation), as this is more of an educational issue.
