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. -- Tim -----Original Message----- From: Evelyn Millions [mailto:evelyn@;MILLIONS.CA] Sent: Friday, November 01, 2002 9:39 AM To: [EMAIL PROTECTED] Subject: Re: Relation of currdepth to disk space Or for an existing qmgr use runmqsc and alter the qmgr. alter qmgr maxumsgs(2000) - Evelyn Hornby, Derek wrote: > ... well one way is to use the parameter > -x nnnnn > as part of the crtmqm command > > -----Original Message----- > From: Halbur, Tim [mailto:HALBURT@;APTEA.COM] > Sent: Friday, November 01, 2002 8:22 AM > To: [EMAIL PROTECTED] > Subject: Re: Relation of currdepth to disk space > > Is there a way to force MQ on the distributed platform to take a checkpoint > rather than waiting for 10,000 operations to occur, which is when > checkpoints are normally taken?
