Hello All,
I am looking for feedback, comments, etc.
We are currently on IDS 10.FC4 on HP-UX 11
- migrating to IDS 10.FC5 on AIX on an LPAR partition on the i595
I have gotten this message in the log while performing some loads/alter
tables/indexes, etc
in development phase.
"13:33:20 KAIO: out of OS resources, errno = 11, pid = 282828"
I decided to turn off KAIO, which is what we have in our current Prod
OLTP system on the HP's.
Here is my ONCONFIG - thanks!
Tom
