Re: VmWare

Sandeil

This have been discussed multiple times in the past.  Try to google for the key 
words  "oracle-l + vmware" and you may see previous discussions

In summary, the agreement seem to be:

Advantages:
Flexibility - You can move the instances around and you can utilize your 
hardware more fully.  Allow uniform management if other services are on vmware


Disadvantages;
Licenses - You pay for all the processor cores that your vmware is running on.  
It does not matter is some cores are dedicated to other services. 

Support - Oracle will support you fine, but if they are having difficulties or 
other life's problem bothering them, they can always use vmware as an excuse to 
dump your case

Overhead - All virtualization technology have an overhead.  If oracle database 
itself it consistently consuming a substantial fraction of the hardware 
resources,   there is not good reason to incur this cost.  Run it directly on 
the hardware and leverage the expensive oracle license more heavily.


I always look at it this way. If the software running on the system is 
expensive to acquire and maintain - oracle, SAP, vertica, microstrategy etc, 
strip the operating system to the bone, run it directly on the hardware.    
Virtualization in those case make sense if it allow you to license less core 
than existing on your physical system.

If its open source projects, virtualize like crazy.  You save on hardware and 
since in this case they are expensive than software, it minimize the effect on 
your company's bank account
