I can't help with TSM/DB2 on Linux, but we run vcs/vxvm/vxfs on AIX for our big
oracle databases. I asked one of the admins what they did and here is his
response.
>The biggest issue we ran into was vxvm doing so many read-aheads it was
>overloading the disks.
>We set /dev/vx/dsk/dgdw1/oradwarch read_nstream=1,read_pref_io=16384
>For each of our file systems to vx won't read so much
>That goes in /etc/vx/tunefstab or you can use the vxtunefs to set them on the
>fly.

Subject: *EXTERNAL* TSM on Veritas Cluster (performance tuning)
Hi guys!
Veritas Cluster Services is the standard clustering software in our company for
physical Linux servers. Our new TSM design is also based on VCS with a mirrored
containerpool on IBM v5010 storage.
Does anybody have experience with performance tuning on VCS or the VxFS
filesystem in combination with TSM? Any tips you like to share?
Thank you very much for your help in advance!
Kind regards,
Eric van Loon
