script - printer scheduler process

[Jagadesh_2]

Hi,

I need a script which should scheck for the printer scheduler process, if it fails it should restart the same.

I will be adding this script to cron to run for every 1 hour time.

Thanks

Some like follows.

lpstat -r || lpsched -v

lpstat -r will let us know whether the scheduler is running or not so..
we need to use that output in the script matching to "scheduler not running" and if this condition is true we can restart the scheduler right?

Yes, that is what lpstat -r does. You are really addressing the symptoms rather than the problem itself. You need to understand why lpsched is dying. Often, simply issueing an lpsched command is not enough because you also need to explicitly remove the SCHEDLOCK and/or the FIFO lock files before doing an lpsched. I would first look for and apply any lp related patches. Fix the problem and you won't need a cron Band-Aid.
