Closed as program error.
Error description
On systems which use INETD to start the MQ listener process amqcrsta a timing window exists which can cause the strmqm command to fail if an instance of the amqcrsta (INETD MQ listener) is started at the same moment. For example, $ strmqm MQINETD WebSphere MQ queue manager 'MQINETD' starting. The queue manager is associated with installation 'Installation6'. The queue manager ended for reason 545284880, ''. rc=xecE_E_SUBPOOL_EXISTS The INETD listener program will fail MQCONNX ended with reason code 2538. (rc=MQRC_HOST_NOT_AVAILABLE)
Local fix
Issue the strmqm command again.
Problem summary
**************************************************************** USERS AFFECTED: Users of WebSphere MQ starting queue managers while MQ network utilities such as the INETD amqcrsta program are active or starting. This issue can also occur with the more commonly used listener runmqlsr program Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A timing window existed such that initialization of the main queue manager process could be affected by concurrent initialization of MQ network processes such as amqcrsta and runmqlsr. This caused the main queue manager execution control process (amqzxma0) to terminate incorrectly.
Problem conclusion
The MQ initialization process has been modified to allow the execution control process to correctly handle concurrent access from MQ network processes. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.7 v9.0 CD 9.0.3 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 ---------------------------------------------------------------
