Tags WebSphere MQ Logs not at the capacity you need? ValerieLampkin 27000182R2 | | Comments (6) | Visits (17453) Tweet Not sure how to increase your WebSphere MQ active logs when your application traffic increases? The ideal scenario would be to plan in advance for the message volume and size MQ logs accordingly at the time the queue manager is created. The total number of primary and secondary log https://www.ibm.com/developerworks/community/blogs/aimsupport/entry/websphere_mq_logs_not_at_the_capacity_you_need files cannot exceed 511 on UNIX® systems, or 255 on Windows. The System Administration Guide has information for calculating the size of the log.However, we often have clients who have had an increase in message traffic and need to then increase their log capacity after the queue manager (QMGR) has already been created and operating for a while. Often, they will receive the error message AMQ7469 for transactions rolled back to release log space.The AMQ7469 message indicates that the log is becoming full and that the queue manager will roll back one or more transactions to release log space. This may be resolved by increasing the number of logs. A common practice is to double the number of logs to see if that resolves problem. One thing you must prevent is using up the file system by setting the number of logs to the point they will not fit on the file system. If new application function has been added recently, then you may want to ensure that applications are not coded such that an unusual long-running unit of work (UOW) would occur requiring the UOW to span a large number of files. Until the work is committed, the logs can not be freed by the queue manager
Configuring WebSphere MQ Error log sizes Posted on December 4, 2012 by T.Rob No, not *that* kind of tuning! I've been keeping a running blog post of questions and answers from the WebSphere MQ Admin seminar this week https://t-rob.net/2012/12/04/configuring-websphere-mq-error-log-sizes/ in Amsterdam, but the more I researched this topic, the longer the answer became. Eventually, it spilled over into its own post. It turns out that the behavior and controls have changed from version to version and even https://developer.jboss.org/thread/248986 across Fix Packs. That means after applying a fix Pack or upgrading to a new version, things might break. For a new QMgr it won't "break" anything but it might not behave as expected if you set the parameters mq error based on the old version. Here then is the story of the many facets of error log size tuning. Q: I need to increase the size of my MQ error logs. Where are the error log file sizes specified? A: The log file sizes can be tuned using the MAXMQERRORLOGSIZE environment variable, the qm.ini file and/or the QMgr attributes in the WebSphere MQ Explorer Extended Attributes panel. If the environment variable is changed, the queue manager and local mq error log applications must be restarted to pick up the change. If the ini file is changed, the queue manager (but not the local applications) must be restarted to pick up the change, after which the value will be visible in the WebSphere MQ Explorer Extended Attributes panel. If the size is adjusted using by altering the queue manager attribute in WMQ Explorer, it takes effect immediately and the value is saved to the ini file by the queue manger. Note that there is no equivalent MQSC command for this attribute. It is available as PCF and WMQ Explorer exposes it in the Extended Attributes panel. Other PCF-based tools may or may not expose this attribute. The features regarding error log size differ slightly by version so here are links and descriptions for each. As of v5.3, the MQMAXERRORLOGSIZE environment variable allowed for increase of the size of the global error logs and the queue manager’s error logs. The problem with this was that any process for which the environment variable was not set would truncate the error logs to 256k. Additionally, on iSeries you needed to delete the existing files in order to make the change as described here. As of V6.0, an attribute was placed in the qm.ini file that eliminated the problem of having to put the environment variable everywhere. But the ini file setting only affected the queue

Vimod Chandra V S Sep 19, 2014 3:03 PM Hi,I have JBOSS 5.1 EAP version which is integrated with IBM MQ 'com.ibm.mq.wmq.jmsra-7.0.1.1.6.rar' resource adapter. I can see one log file 'mqjms.log' is getting created in my JBOSS home directory when I start my server and receiving messages from IBM MQ. Where is the location of this file and the name of this file configured in my JBOSS configuration ? I need to disable or control the size of this log file bcause sometimes it grows up to a big size file! Someone please help.. 1094Views Tags: none (add) This content has been marked as final.

Doug Grove Oct 10, 2014 11:27 AM (in response to Vimod Chandra V S) IBM MQ logging uses the IBM common services for logging. You can set java JVM properties:"com.ibm.msg.client.commonservices.trace.status" value="OFF""com.ibm.msg.client.commonservices.trace.level" value="0""com.ibm.msg.client.commonservices.trace.append" value="true""com.ibm.msg.client.commonservices.trace.startup" value="true""com.ibm.msg.client.commonservices.trace.maxBytes" value="-1""com.ibm.msg.client.commonservices.trace.limit" value="2097152""com.ibm.msg.client.commonservices.trace.count" value="1""com.ibm.msg.client.commonservices.trace.standalone" value="true""com.ibm.msg.client.commonservices.trace.errorStream" value="${jboss.server.log.dir}/wmq-trace-error.log""com.ibm.msg.client.commonservices.trace.outputName" value="${jboss.server.log.dir}/wmq-trace.log""com.ibm.msg.client.commonservices.log.outputName" value="${jboss.server.log.dir}/wmq.log""com.ibm.msg.client.commonservices.log.status" value="ON""com.ibm.msg.client.commonservices.log.maxBytes" value="-1""com.ibm.msg.client.commonservices.log.limit" value="2097152""com.ibm.msg.client.commonservices.log.count" value="1""com.ibm.msg.client.commonservices.log.append" value="true""com.ibm.msg.client.commonservices.ffst.suppress" value="-1"i.e, in you run.conf file-Dcom.ibm.msg.client.commonservices.log.count=5 -Dcom.ibm.msg.client.commonservices.log.maxBytes=1000000Hop
