Hi,

Kindly advise if there are any restrictions on having an Oracle db running over 11g to be installed in a VMware?

The issue is that we are having performance degradation between the physical and the virtual environment keeping in mind that we have the same resources allocated for both environments.

Should be consider that in general the virtual environment is slower than the physical one when it comes to having Oracle 11g?

Any replies are highly appreciated.

Welcome to the forum. Please read our OraFAQ Forum Guide and please read How to use [code] tags and make your code easier to read

My experience is that disc I/O is usually rubbish in any virtualized enviuronment. Doesn't matter whether it is VMware, VirtualBox, or Xen. Always rubbish. Your system administrators refuse to believe this, so run the dbms_resource_manager.calibrate_io routine on both the virtual and the physical servers. That should convince them.

Thank you for the reply John,

So if I understand correctly, you would recommend moving to a virtual environment where by the performance will be way better than the physical environment.
