Below is my customers issue. I am stuck on this one. I would appreciate
if someone could help me out on this. Thanks in advance!
ZFS Checksum feature:
I/O checksum is one of the main ZFS features; however, there is also
block checksum done by Oracle. This is
good when utilizing UFS since it does not do checksums, but with ZFS it
can be a waste of CPU time.
Suggestions have been made to change the Oracle db_block_checksum
parameter to false which may give
Significant performance gain on ZFS.
What are Sun's stance and/or suggestions on making this change on the
ZFS side as well as making the changes on the Oracle side.
