APAR status
Closed as program error.
Error description
MQ starts a sidecar process for each non native application interfacing with MQ (mqmtns library). MQ returns reason code 2195 (MQRC_UNEXPECTED_ERROR) for numerous reasons. For non-native MQ applications, one reason may be that the associated sidecar process has disappeared. Such a message from the MQ non native library mqmtns shows up in EMS: MQMTNS MQPUT handshake invalid reply grc 201 Guardian or User Defined Error 201 countread 0.
Local fix
A reconnect (MQCONN) does not solve the problem. The application needs to be restarted.
Problem summary
The sidecar process is not prepared to deal with multiple process opens. If another software product (monitoring, security ,etc.) opens and closes an MQ sidecar process, the MQ sidecar process will terminate when that other processcloses its connection to it.
Problem conclusion
The sidecar accepts process open calls only from it's ancestor process, which is the MQ non native application (mqmtns). Other process open calls will be rejected. --------------------------------------------------------------- The fix is targeted for delivery in maintenance level 8.1.0.25 of IBM MQ for HPE NonStop 8.1.
