CA1E: CICS 3270 Bridge Passthrough



SupportPac CA1E provides the CICS 3270 Bridge Passthrough transaction that allows you to run a CICS 3270 user transaction from a 3270 terminal, using the CICS 3270 Bridge facility.

Download Description

This SupportPac provides the CICS 3270 Bridge Passthrough transaction that allows you to run a CICS 3270 user transaction from a 3270 terminal, using the CICS 3270 Bridge facility rather than standard CICS terminal control function.

You can use the supplied transaction to evaluate whether a CICS 3270 transaction is suitable to be driven using the 3270 Bridge. It also allows you to examine the 3270 data streams created by the bridge exit and log them for further analysis. You can then use this information to write your own end-user application to drive the CICS 3270 transaction instead of a real terminal.

The Passthrough transactions work with the CICS supplied sample bridge exit DFH0CBRE, using temporary storage or transient data queues to pass 3270 data streams to the Passthrough, or with the MQSeries supplied bridge exit CSQCBE00 if using MQSeries queues. Additionally, Version 3.0 for CICS TS V2.2 now supports the new Link3270 method of bridging to 3270 based applications.
