RE: Data Queue's

[Bob Crothers <bob@xxxxxxxxxxxxxx>]

The info gets written to the data queue when the splf shows up in a 
ready (RDY) status...not before.

What is the CPF message you are getting?

Also, if the async program is getting its input from the data queue, 
why have it wake up every 30 seconds and check it?  Why not just 
specify "wait forever" when doing the QRCVDTAQ?  That way it can 
respond to the entrys right away with very little delay.  It is 
possible that the splf shows up, data queue entry gets sent but before 
you check it, something else is happening to the splf..

Subject:        Data Queue's

I need some information on when data gets written to a data queue when 
a spool
file is created.  I am supporting a utility (written by a former 
employee of
course) that reads a data queue to find newly created spool files. 
 The
utility is an asynch program that fires up every 30 seconds and moves 
the
spool file from one output queue to another for printing and 
archiving.
Occassionally the utility misses a spool file.  When I manually move 
the spool
file to another output queue and back again, the utility is able to 
find and
process it.

I suspect I have a timing problem...that the data queue is loaded with
information for the spool file before the spool file status is changed 
to
'RDY'.  The utility program grabs information from the data queue and 
tries to
move the spool file but fails because it is not in RDY status.

I've tried changing the SCHEDULE parameter on the printfile to *IMMED 
with no
success.  Can someone help me understand exactly when information is 
written
to the data queue and can it be controlled to coincide with the change 
of the
status from 'OPN' to 'RDY'?
