Hi All

A while back I posted about an issue with DB2 tablespaces in TSM 6 on
ZFS filesystems where issue occur because ZFS does not support direct
IO.

IBM has issued a technote at
http://www-01.ibm.com/support/docview.wss?uid=swg21437784 about this.
I am posting again because should the active log be on ZFS as well a
similar problem occurs, and direct IO has to be turned off for it too.

to see your setting, as the instance owner run

db2set -l DB2_LOGGER_NON_BUFFERED_IO

OFF means no direct IO
AUTO means direct IO for DB2 active log, not for any other - this is
the default
ON means DIO for all DB logs

set it to off with

db2set DB2_LOGGER_NON_BUFFERED_IO=OFF

Hope this helps

Steve
