We are running 8.1.7.4 on Solaris 8 64-bit with Veritas Database Edition for Oracle 3.5MP1.

What is the ideal file system caching policy? The options are "closesync direct dsync unbuffered tmpcache"

This is your standard OLTP database. Or should the caching policy change depending upon the data there? ie: We have dedicated logging disks, dedicated temp and undo disks, and dedicated archive disks.

Thanks for any info,
CC
