Schedule execution of oncheck commands
Posted in 2009
Topics: Server Administration
Hello, friends.
We´re on IDS 11.50.FC4 on a linux_64 environment.
On our old instances (9.40), we had a script to run regularly, some
oncheck commands on our instance.
Does it applies also to the 11.50 version? Is it needed to execute on a
regular basis, or not?
Thanks and regards.

The straight answer is that it was NEVER necessary, just prudent. Honestly,
I'm not a big fan of running onchecks frequently. Partly the attitude is a
throwback to the 7.xx days when all onchecks locked the object being
checked, so we didn't have much of a window when it was safe to run
onchecks. Partially, it's a matter of faith that IDS doesn't corrupt its
data on disk very often and partially insistence that it should NEVER get
corrupted - after all what are we paying all those support $$ for
otherwise? Finally, the attitude is mostly because I rarely find anything
wrong, which I assume matches with your own experiences.
If the engine says there's a problem, or if I suspect one, that's the time
I'll run the onchecks.
Exception? I like to have an oncheck -pe output report and a
dbschema/myschema output report (for each database) available on disk in
case I have to recover data manually from an archive or from
catastrophically damaged disks (either using archecker, my own recovery
tools, or be calling tech support). I do want to have those reports
periodically (the oncheck -pe weekly and the schema updates whenever the
live schema is modified).

Ok Mr. Art!
That solved all my doubts, really.
Thanks for your attention.
