I agree with the blocking concept. However for your current problem if you
are using circular logging you are probably running out of log file space
so I'd suggest you increase the number of log files you are using. The
other parameter you may encounter trouble with is MAXUMSGS i.e. the number
of maxmimum number of uncommitted messages.

I know this is an obvious suggestion but I did not see anyone make it this
time.
Why not block the records into say a 32k block for a nice easy round
number...
when you send each 380 byte record they each get their own 324 byte MQMD.
we block everything now when sending groups of messages or files the
performance improvements are dramatic especially when each record is so
small - we were sending 30 bytes messages and each one got a 324 MQMD -
kinda ridiculous huh.

Subject: Am I asking too much to MQ?!?! (PROTOm@il:200211221113
CENTROSIM)
As many of know, I am sending a file from a Win2K MQ to a MVS-based MQ.
For some file integrity reason I am sending all records within
the same SYNCPOINT: if all records are gone (I.E. my app reached the EOF
without any bad retcode from MQ), I will issue a MQCMIT once.
Today the input file is about 6000 rks, about 380 byte each, and MQ
return a retcode 2 with reason 2003, after 4754 rks.
Am I asking too much?!
