RE: DBMS Job vs C Daemon
While I agree that dbms_job is the right way, we had lots of problems with dbms_job suddenly failing (i.e. it just stops working) in 9011 and 9012 versions of database. Finally it was something to do with job queue processes, with the help of OWS we fixed it. BUT, I still don't trust dbms_job on our 9i production db and hence all critical jobs are run by our close friend 'cron', it works!. Raj __ Rajendra Jamadagni MIS, ESPN Inc.

RE: DBMS Job vs C Daemon
I also agree, cron WORKS well ! The only thing I would add to cron jobs (shell scripts) is to use a semaphore file. e..g. --- semfile=/tmp/$0.RUNNING if [ -f $semfile ] ; then exit ; fi touch $semfile DO SOME SHELL STUFF rm $semfile exit --- This way no matter how frequent you run the job or how long it takes the job to run, it still works. I had a developer run a job every 5 mins but the job took 15 mins to run, so you can guess what begins to happen after a few days :-) Gene [EMAIL PROTECTED] 03/15/02 08:18AM While I agree that dbms_job is the right way, we had lots of problems with dbms_job suddenly failing (i.e. it just stops working) in 9011 and 9012 versions of database.

Re: DBMS Job vs C Daemon
Raj, Was it some kind of patch for 9011 or 9012, which fixed dbms_job? Could you provide some details? It's very important for us, because we rely heavily on dbms_job (NT environment, looking to upgrade to 9i).

RE: DBMS Job vs C Daemon
..which is why we have a shell script that runs out of cron and checks on database jobs. Here is the SQL that we use to find jobs with problems: /* Check for broken jobs or jobs that have failed more than 8 times. */ /* Also check for jobs that should have run in the last day, but haven't. */ select job, failures, broken from dba_jobs where failures 8 or broken = 'Y' or sysdate - next_date 1 spool check_jobs.lis / spool off Some jobs have to run in the database, such as snapshot refreshes.
