Error description
A client application connecting to a server using MQSERVER environment variable, gets 2058(MQRC_Q_MGR_NAME_ERROR) from MQCONN. This is because of a change in MQ v7 that led to the cached value of MQSERVER being used during the MQCONN call. In MQ V6, this caching mechanism was not present and hence it could pick up the latest MQSERVER variable at each MQCONN.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: WebSphere MQ client users where, 1. Application disconnects from one queue manager and tries to reconnect to different queue manager on different host. 2. MQSERVER environment variable is used in the application. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: When the client application connects to a server using MQSERVER environment variable, WebSphere MQ caches the value in the ServerConnectionParms attribute. This cached value will be used, when the application tries to reconnect to a different queue manager on a different server instead of the new MQSERVER variable. Since the new value is not used during connection, the client application gets 2058(MQRC_Q_MGR_NAME_ERROR) error during MQCONN.
Problem conclusion
WebSphere MQ code has been modified such that during each MQCONN, the newly specified MQSERVER value is used in connecting to the queue manager. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.2 -------- -------------------- Windows U200316 AIX U829807 HP-UX (PA-RISC) U829678 HP-UX (Itanium) U829681 Solaris (SPARC) U829806 Solaris (x86-64) U829680 iSeries tbc_p700_0_1_2 Linux (x86) U829677 Linux (x86-64) U829676 Linux (zSeries) U829682 Linux (Power) U829679 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 ---------------------------------------------------------------
