Hi All,
Are there any specific changes required to the Oracle parameters to improve performance when running Oracle 10g on Solaris Virtual Machine? Our problem is that direct path writes to both datafiles and to temps is running at 1 MB/s. Storage is RADI1, internal with HP SmartArray, host OS is ESXi. Oracle datablock size is 8K, VMFS is 1 MB. What makes me look for any Oracle settings is that file copy or ftp runs pretty fast. Problem is when there are database writes. Even a simple CREATE TABLE AS SELECT... statement for a 0.5 GB table takes 9 minutes. I am suspecting the interaction between Oracle and VMFS is causing the slow down, but have not been able to find any documentation about any best practice about it. Any hints?
Thanks,
Nikhil
