MQCONN - Connect queue manager

 

The MQCONN call connects an application program to a queue manager. It provides a queue manager connection handle, which the application uses on subsequent message queuing calls.

• On z/OS, CICS applications do not have to issue this call. These applications are connected automatically to the queue manager to which the CICS system is connected. However, the MQCONN and MQDISC calls are still accepted from CICS applications.

• On i5/OS, applications running in compatibility mode do not have to issue this call. These applications are connected automatically to the queue manager when they issue the first MQOPEN call. However, the MQCONN and MQDISC calls are still accepted from i5/OS applications.

  Other applications (that is, applications not running in compatibility mode) must use the MQCONN or MQCONNX call to connect to the queue manager, and the MQDISC call to disconnect from the queue manager. This is the recommended style of programming.
