ChannelAutoDefExit (MQCHARn)
This is the name of the user exit for automatic channel definition. If this name is nonblank, and ChannelAutoDef has the value MQCHAD_ENABLED, the exit is called each time that the queue manager is about to create a channel definition. This applies to channels of type MQCHT_RECEIVER, MQCHT_SVRCONN, and MQCHT_CLUSSDR. The exit can then do one of the following:
- Create the channel definition without change.
- Modify the attributes of the channel definition that is created.
- Suppress creation of the channel entirely.
Note:Both the length and the value of this attribute are environment specific. See the introduction to the MQCD structure in WebSphere MQ Intercommunication for details of the value of this attribute in various environments.This attribute is supported only on AIX, HP-UX, iSeries, Linux, Solaris, Windows, and z/OS. On z/OS, it applies only to cluster-sender and cluster-receiver channels.
To determine the value of this attribute, use the MQCA_CHANNEL_AUTO_DEF_EXIT selector with the MQINQ call. The length of this attribute is given by MQ_EXIT_NAME_LENGTH.
