Yeah, my advice is don't do it. Linux to Windows? Is this guy a MS employee perhaps?

Subject: Oracle on windows 2003 on vmware  


Our corporate wiz kid has decided to migrate our Oracle 10g database from Linux to Windows2003 on Vmware.

Are there any special setup instruction needed to make this work properly? Any references that I might have missed? I searched the OTN but did not find anything that jumped out at me.  

Linux server. 1 CPU, 4 GIG ram, 3 internal mount points for data. Oracle setup with 1.6 GIG SGA  

Windows VMWARE server. 1 CPU, 4 GIG ram, 3 mount points on SAN(2 fiber channel 1 SATA) data. Oracle setup with 1.6 GIG SGA  

Both servers have the same tables, partitions, and data loaded on one mount point. In the Windows case it is the SATA SAN.

I set timing on.

I run the query select count(*) from a table that has 500,000,000 records and

 Linux = 4 min, 24.83 seconds

Windows = 19 min,53.19 seconds  

The results are proportionatly the same for the other tables that have millions of records.  

Is there any helpful hints that we might have missed when we set up the VMWARE ESX server for windows/oracle?  

When I google for VMWARE and Oracle the results are for Linux and RAC not windows. Maybe they are trying to tell me something.  

Any usefull suggestions?
