Slow Oracle on VMWARE

HabibApr 5 2012 — edited Apr 6 2012
Hi

I have installed Oracle 11g XE on different Virtual Machines some running on XEN and some on VMWARE. Hardware configuration is almost the same. Oracle parameters are exactly same.

I have noticed that instances running on VMWARE write data very slow as compared to those running on XEN. SELECT statements work fine. INSERT/UPDATE are slow only.

I will be thankful if someone can help me if I can tune it on VMWARE?

Thanks.

Habib

I would be surprised if it wasn't slower. You have added several layers of unsupported software to the stack.
