Purpose: The APPC command can be used to enable or disable the log connection subtasks running in the DIF address space. These subtasks control the connections defined by the DEFCONN control cards, which are used to connect DIF DD logs to MQSeries message queues, the system logger, and/or TCP/IP links. The APPC command can also be used to list the active connections and options currently used by DIF.
The ENABLE APPC command will force the DIF address space to re-attach the APPC and MQSeries subtasks. The DISABLE APPC command will force DIF to detach the subtasks.
An APPC command without ENABLE or DISABLE preceding the command will list the APPC status information.
