We often hear the warnings of mixing Oracle and VMWare, with claims that the combination will end up costing you a fortune. I’d like to shed some light on this, as it is by no means needs to be true – particularly when you take a holistic approach and look at the overall situation of licence usage within the business.
What we continuously find when working with clients is that there are ways to get the best of both worlds, while getting the benefit of a custom framework that fits your business like a glove.
The same rules apply
It’s important to remember that using ANY form of virtualisation should be viewed the same as using the old physical hardware instead. Thinking back to the old days, you may have had a primary system running, with a failover standby to 10, 20 or 30 different systems. This means that you would have been expected to license all those systems and pay for them. This all works the same way in a VMware environment.
Know your direction
The bottom line is that if you don’t quite know what you’re doing – and you don’t have a full understanding of the ramifications of what you’re doing within the VMWare environment – then you could by all means end up with a larger bill than expected. However, if you understand where you want to be and you know what business benefit you’re going to get from a given level of availability and failover, then there is no reason why you shouldn’t use VMware (or any other hypervisor) to deliver against those requirements.
Plan for what you need
In some scenarios you may be required to split your server farms out in order for Oracle to only exist within a specific server farm, and in another situation you may choose to do it just on single, stand-alone physical and standby environments. Regardless of the route you take, you must plan for what you require and ensure you license accordingly. It’s when you take action without fully working through the potential ramifications that you can end up getting yourself into trouble.
OVM as an alternative
From our perspective, you may also want to consider OVM (Oracle hypervisor) as an alternative to VMware. OVM performs consistently, it’s feature-rich and it squares up well to VMWare whilst being fully supported from Oracle for running Oracle databases and can help save you some of your licensing headaches.
