Customizing the CICS bridge

 

The WebSphere MQ-CICS bridge is an optional component that allows WebSphere MQ to input and output to and from existing programs and transactions that are not WebSphere MQ-enabled.

This chapter describes what you have to do to customize the WebSphere MQ-CICS bridge. The bridge is described in the WebSphere MQ for z/OS Concepts and Planning Guide and WebSphere MQ Application Programming Reference.

Prerequisite APARs

To run 3270 transactions, be using CICS Transaction Server for OS/390 V1 Release 3 or later. V1 Release 3 requires APAR PQ23961.

Before we can run the bridge ensure that your z/OS system has both the CICS and WebSphere MQ components in place. To run transactions using the bridge, have the LE runtime environment installed, and have a link to the LE runtime library SCEERUN included in the z/OS link list. For further information about the link list, see Task 3: Update the z/OS link list and LPA.
