So I guess this means that you still have to bounce the QMGR before cleaning
up the logs because the message for reductiopn of the log files will not
show the true status of the logs after the rcdmqimg???????????????????

Emile,
rcdmqimg has nothing to do with checkpoints.
Here's an exchange I saved on this topic:

I am sorry.
I checked and the answer to question two is NO.
Thanks,

Richard,
Below is response to your question:
*********************************************************************************************************
Rcdmqimg command does not force a checkpoint. So AMQ7468 message does not
get issued as a result of rcdmqimg. It is only issued at the end of a
checkpoint. There is no direct relationship between recording a media
image and taking a checkpoint.

Thanks,

I see messages AMQ7467 and AMQ7468 always entered in the AMQERR0x.LOG
together,
at about the same time. Our shop issues rcdmqimg everyday at 6:00am but we
never see AMQ7468 issued when the command completes.
I have two questions:
1. Does AMQ7468 only appear when a checkpoint is done?
2. Does each occurrence of AMQ7468 in the error log reflect the last time
rcdmqimg was issued (which was at 6:00am in our case)?
Thanks.

Correct me if I am wrong, but does the Record Image (rcdmqimg) not force
a check Point?

The max uncommitted messages parameter has to do with the maximum number
of
uncommitted messages within a unit of work that an application can have
before it must issue an MQCMIT.

Please respond
to MQSERIES
I don't believe this would have the affect that I'm interested in,
though I
admit I might be mistaken in my beliefs.
The changing of the value for max uncommitted messages will affect the
size/number necessary for log space, but, I don't know that it would
affect
the checkpoint processing. Per Paul's note regarding when queue space
is
cleaned up, it basically takes two checkpoint's after a queue has been
emptied to clean up the space on disk. What I'm interested in doing is
forcing those checkpoints to come more frequently than the default of
10,000
(per the documentation) operations between checkpoints. I don't know
that
max uncommitted would have any affect on that processing.
I was hoping for an entry in say the qm.ini file that would tell MQ to
take
these checkpoints more frequently, say every 1,000 operations.
Obviously
there would be a performance affect by lowering this number too far,
but,
I'm more interested in disk space at this time.

Or for an existing qmgr use runmqsc and alter the qmgr.
alter qmgr maxumsgs(2000)
