In MQSeries opening the Queue is the first step. This sample program tell you the list of options available for MQOPEN:
-Open a queue and specify that all messages put to that queue must be directed to the same instance of it. -Open a queue to allow you to put messages on it -Open a queue to allow you to browse messages on it -Open a queue to allow you to remove messages from it -Open an object to allow you to inquire about and set its attributes (but you can set the attributes of queues only) -Open a topic or topic string to publish messages to it -Associate context information with a message -Nominate an alternative user identifier to be used for security checks -Control the call if the queue manager is in a quiescing state * -------------------------------------------------------* WORKING-STORAGE SECTION. * -------------------------------------------------------* * * W02 - Queues processed in this program * 01 W02-MODEL-QNAME PIC X(48) VALUE 'CSQ4SAMP.B1.MODEL '. 01 W02-NAME-PREFIX PIC X(48) VALUE 'CSQ4SAMP.B1.* '. 01 W02-TEMPORARY-Q PIC X(48). * * W03 - MQM API fields * 01 W03-HCONN PIC S9(9) BINARY VALUE ZERO. 01 W03-OPTIONS PIC S9(9) BINARY. 01 W03-HOBJ PIC S9(9) BINARY. 01 W03-COMPCODE PIC S9(9) BINARY. 01 W03-REASON PIC S9(9) BINARY. * * API control blocks * 01 MQM-OBJECT-DESCRIPTOR.
