MQCNO_RESTRICT_CONN_TAG_Q_MGR

 

public final static int

This option indicates that connection tag use is restricted within the queue manager. This connection option is supported on z/OS only. It requests shared use of the connection tag within the local queue manager. If the connection tag is already in use in the local queue manager, the MQCONNX call can succeed provided that the requesting application is running in the same processing scope as the existing user of the tag. If this condition is not satisfied, the MQCONNX call fails with reason code MQRC_CONN_TAG_IN_USE. The outcome of the call is not affected by use of the connection tag elsewhere in the queue-sharing group to which the local queue manager belongs.

On z/OS, applications must run within the same MVS™ address space in order to share the connection tag.

If the application using the connection tag is a client application, MQCNO_RESTRICT_CONN_TAG_Q_MGR is not allowed.
