[AOLSERVER] URGENT AOLSERVER + ACS + SOLARIS
We are running a production AOLServer 3.3.1 + ad13 on solaris We have 2 machines, duplicates of each other. Machine A suddenly, without error messages stops running scheduled procs !! Machine B continues to perform flawlessly The machine is running acs classic 4.2 tcl, 90% webmail which has been running perfectly well under stress and load for months... Urgent help/suggestions are appreciated .. Allan Regenbaum Digital People

Did you turn on clustering? I think tasks only run on the master in a cluster.

Hi Barry .. the machines are decoupled they are in no way dependent upon each other .. I just mentioned that to show that teh setup works perfectly on one machine and is failing on another identical config ... seems that as the production is loade dup something is causing one of our sheculed procs to not return control of the thread, thereby hanging all the other scheduled procs. ? -Original Message- From: AOLserver Discussion [mailto:[EMAIL PROTECTED]]On Behalf Of Barry Books Sent: Tuesday, October 30, 2001 9:14 AM To: [EMAIL PROTECTED] Subject: Re: [AOLSERVER] URGENT AOLSERVER + ACS + SOLARIS Did you turn on clustering?

I have *always* had a problem with scheduled procs, to the point where I now simply use a cron job and curl to tell AOLserver to do something Michael Allan Regenbaum DP wrote: > We are running a production AOLServer 3.3.1 + ad13 on solaris > We have 2 machines, duplicates of each other. > > Machine A suddenly, without error messages stops running scheduled procs !! > Machine B continues to perform flawlessly > The machine is running acs classic 4.2 tcl, 90% webmail which has been > running perfectly well under stress and load for months... > > Urgent help/suggestions are appreciated .. > > Allan Regenbaum > Digital People
Re: [AOLSERVER] URGENT AOLSERVER + ACS + SOLARIS
Are you exec'ing anything in the scheduled proc? I've seen some weirdness in the past with execs getting hung, although not much recently. I think it was more of an OS (Linux) issue. We've used scheduled procs for years w/o any problems on all of our servers, though we only have a handful (of scheduled procs), like 10. whereas I've read that ACS has lots of them. A suggestion would be to run more complex stuff in detached threads that you launch from the scheduled proc rather than in the scheduled proc itself. Then if it screws up, you won't tie up the scheduler thread.

Make sure that you explicitly release database handles and ns_sets in scheduled procs. A connection thread has a bunch of cleanup that it does, and none of it gets done from a scheduled proc thread. Pete.

Is this true of detached threads too - no cleanup? We're probably fine, but nice to know when to be extra careful.-Jim > > Make sure that you explicitly release database handles and ns_sets in > scheduled procs.

That proc will tie up the scheduler thread, so the scheduler will never get a chance to run other scheduled procs.
