Re: MQ logging
Brian, Only the persistent messages are logged at every UOW. On Windows, you can find the log files in \Your MQ path...\log\qmgrName.

Re: MQ logging
There isn't a message log in mqseries, it's only a transaction log. Gunter Am Fr, den 18.06.2004 schrieb Brian Weston um 22:53: > Sorry for the simple question... I'm very new to MQ...

MQ logging
Title: Message Sorry for the simple question... I'm very new to MQ... By default does MQ log all messages that it transmits? If so, where is that log. If not, is it possible to configure MQ to track all the messages that it transmits? Thank you! Brian
Re: Question on MQ logging
Guys, I have asked this question before (please see my email below), but i think i was more interested in getting numbers for my logging issue that i did not bother asking. Now i am at a point where i need to understand if the design makes any sense. ** * all messages in the queue being marked persistent * Using static queues * size of each message will be around 3MB * Also this is a design where each QM may have around 1000 or so users (each user has a queue for herself/himself) but at a given time only 150 users (queues) would be trying to use the Queue manager. (hhmmm that makes me think, is it ok to have that many users connect to the same QM at the same time or introducing a diff QM would be better option?) ** Does or Can a Queue Manager really support 1000 queues ? Assuming not more than 200 people connect at the same time. Because this design involves static queues it could be storage intensive right ? If so, does anyone have an idea of what numbers we are looking at ? Like storage wise or machine spec ? Also i hope there are not any legalities involved in this, especially because the clients are freely available.

Re: MQ logging
1. Primary log - Is the log that the QMGR will define when you issue a crtmqm, when this log is full, the QMGR will define the secondary log. Attached please find a document about logging,Hope this helps. 2. rcdmqimg - The rcdmqimg command writes an image of an object, or group of objects, to the log for use in media recovery. Hope this answers all your questions. -Original Message- From: Scurlock, James E [mailto:[EMAIL PROTECTED]] Sent: 27 January 2003 04:30 To: [EMAIL PROTECTED] Subject: MQ logging I need some information on how MQSeries logging works (read the manuals, but didn't find the level of detail I'm after).

** Note: This e-mail is subject to the disclaimer contained at the bottom of this message. ** : James, If you have time you might find it helpful to put/get some persistent and and non-persistent messages, transactional and non-transactional, in an isolated test queue manager and then use the 'dmpmqlog' utility to look at the log records, quantity and size, that were created as a result of the MQ activity. You can also run the 'rcdmqimg' utility to see the log records that are created and the relationship to the messages in AMQERR01.LOG re the oldest log file needed for recovery.
