Credit Check sample on z/OS

This information contains points to consider when using Credit Check sample.

• Developing an application that runs in more than one environment
• Use a model queue to create a temporary dynamic queue
• Use a correlation identifier
• Set and passing context information
• Use message priority and persistence
• Starting programs by using triggering
• Use reply-to queues
• Use alias queues
• Use a dead-letter queue
• Use a namelist
• Testing return codes

The application uses these MQI calls:

• MQOPEN
• MQPUT
• MQPUT1
• MQGET for browsing and getting messages, using the wait and signal options, and for getting a specific message
• MQINQ
• MQSET
• MQCLOSE

The sample can run as a stand-alone CICS application. However, to demonstrate how to design a message queuing application that uses the facilities provided by both the CICS and IMS environments, one module is also supplied as an IMS batch message processing program.

The CICS programs are delivered in C and COBOL. The single IMS program is delivered in C.
