Re: Are data queues reliable?

[DrFranken <midrange@xxxxxxxxxxxx>]

Yes love this method, DLYJOB is so 'fixed' :-)  Also used to request 
statistics and such from the job in addition to shutting down for example.

We would pair a data area with the data queue and the data area was the
object we would lock to know there was a process reading the queue 
entries. Any job that needed the queue processor running would attempt 
to lock the dtaara at startup and if it could get a lock initiated the 
processing program. If it couldn't get the lock it knew the processor 
was up and running. Just one way to handle that of course and this 
particular method doesn't work if you want multiple jobs processing the 
same queue.
