Performance issue with Solaris 8.0 and Oracle 8.06

 Experts comments sought for the following limited glimpse of problem:

Two Sun E250 machines, both 2GB mem, two procs, 6 9GB drives, both ufs filesystems only, (no logical volume managers), both up to the recommended/suggested patch levels, connected to same subnet, same datasets tested for both, same /etc/system params, same size SGA..

without any special changes, running same table loads on the Solaris 8.0 box is slower than Solaris 2.6 box, mostly with updates rather than initial writes.

Turning forcedirectio on for the datavolumes has the performance of the 8.0 machine at about 80% of the 2.6 box. We have tried enabling intent logging on the 8.0 box with limited success. We have tried many variations with systems params including 8i upgrade to the 8.0 Solaris box with no real change in performance over the 8.06 Oracle on the 8.0 box etc...

Does anyone know of any issues with this OS and Oracle combination or has anyone resolved a similar revision combination issue that would be kind enough to recommend an action or supply a pointer? Received on Tue Feb 20 2001 - 00:26:36 CST
