Closed as program error.
Error description
Consider the following setup: QMGR.A SDR Channel : A.TO.B QMGR.B RCVR Channel : A.TO.B Any kind of Channel: UNRELATED.CHANNEL CERTLABL(MISSING.CERT) is set on UNRELATED.CHANNEL where MISSING.CERT is a non-existent certificate. When executing STOP CHANNEL(A.TO.B) on QMGR.A: QMGR.B displays: "AMQ9645E: Certificate 'MISSING.CERT' missing on channel 'UNRELATED.CHANNEL'" and "AMQ9999E: Channel 'A.TO.B' to host '***' ended abnormally" when A.TO.B had in fact ended normally.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of MQ that use the CERTLABL attribute of channels to manually set SSL certificates for individual channels. This issue affects only inbound channels to the queue manager, where the queue manager is the receiving end of a TLS connection made by a remote client or queue manager. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: An error in the MQ code caused a certificate label error to linger in the system. This would later cause a channel to report an abnormal end, when it had in fact ended normally.
Problem conclusion
The MQ code has been changed so the error is reported immediately and does not persist for longer than needed. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD TBC. v9.1 LTS 9.1.0.6 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 ---------------------------------------------------------------
