We have lots of Oracle systems running on VMware- maybe as many as 500
vmware guests.  Just a couple of points:

 

1)      Performance can be variable- depends on the load of the other
guests, and vmware itself has significant overhead.  We discourage
putting production databases on vmware due to this issue.  It can be
difficult to tune Oracle on vmware due to the effect of other guests.

2)      Test / dev machines work great on vmware.  

3)      We never put RAC on VMware.  It can be made to work, but if the
customer has the money for RAC licenses, then they probably want the
best performance possible and can spring the money for native machines.

That is not quite correct.

 

Please see MOS 249212.1 to determine if you can live with their VMWare
support policy.

 

         My question is: Is anyone else running Oracle in the VMWare
virtual environment?  If so, have you run into any issues and how much
did Oracle support help you?

The issues I have encountered running Oracle on VMWare have mostly been
oracle related.

Those that were vmware related were obviously vmware problems. eg.
clock not keeping time on linux.

 

The databases I use in our lab for testing are all VMWare on linux and
windows.

We even have an entire eBusiness suite system running on a small server
under VMWare.

The only issue there has been keeping the clock synced.  That's a VMWare
tools issue.
