Connecting to MQSeries Applications

Use the "-D5" option to compile your ACUCOBOL-GT application for the MQSeries client. This is a data format switch. The runtime will not require any special switches to use the IBM library routines or copybooks once you have compiled with this option.

Note: Use caution when compiling with any other "-D" flags because this could cause problems in compilation.

Once the MQSeries Client software is loaded and configured, you can set up a queue on the message queue manager or server to receive messages. We support calls to the message queues and the message queue manager. Our ACUCOBOL-GT runtime can use the following MQSeries calls to communicate with other MQSeries applications by sending and receiving messages:

Connection Calls:
MQCONN - Connect to queue manager
MQCONNX - Connect to queue manager (extended)
MQDISC - Disconnect queue manager

Queue Manipulation Calls:
MQOPEN - Open object (usually a queue)
MQCLOSE - Close Object
MQINQ - Inquire about an object
MQGET - Get a message off of the queue
MQPUT - Put a message on the queue
MQPUT1 - Open, put single message, close in one call
MQSET - Set object attributes

Transaction Support:
MQBEGIN - Begin Unit of work
MQBACK - Back out changes
MQCMIT - Commit changes
