APAR status
Closed as program error.
Error description
The queue manager has many objects, or is running on a slow machine. The dmpmqcfg command runs for approximately 30-60 seconds, then ends with a timeout error: "MQSC timed out waiting for a response from the command server."
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of dmpmqcfg attempting to dump definitions from a queue manager that is running slowly due to resource restrictions, and/or has many objects defined. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: dmpmqcfg works by sending "inquire" commands the command server, and receiving responses. If the queue manager (or its command server, or the machine it is running on) is busy, then the responses can take a "long" time to come back. When it has sent the requests, the main routine of dmpmqcfg enters a loop waiting for all work to be complete on a separate thread. In this loop, every 30 seconds, a health check is done. The health check looks at the number of commands processed, and if this number has not increased since the last time we checked (ie. 30 seconds ago) then dmpmqcfg assumes a failure has happened, and ends the program. But this condition also happens in the case documented here: the queue manager is slow in responding for reasons of resource shortage or large number of definitions.
Problem conclusion
A command line switch -w has been added to dmpmqcfg. Via this switch the user can supply an argument which is the acceptable timeout when waiting for a reply message from the command server. The default is 60 seconds. So, for example, to use a value of 120 seconds: dmpmqcfg -m QMNAME -a -w 120 --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.9 v8.0 8.0.0.8 v9.0 CD 9.0.4 v9.0 LTS 9.0.0.2 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
