CICS System Definition Guide. Part 3, “Defining intercommunication resources,” on page provides guidance for resource definition. It tells you how to define. Introduction to CICS intercommunication. It is assumed that you are familiar with the use of CICS as a single system, with associated data resources and a. Recovery and restart in interconnected systems. This section describes those aspects of CICS recovery and restart that apply particularly in the.

The method of setting breakpoints depends on whether an application intercommunicwtion running in the local or remote region. The system automatically establishes an abend trap for all abends that occur on the terminal in region AOR1. Because you cannot always use the same terminal for the back-end transaction, you cannot predict the terminal ID.

The dump will intercommunicatjon the abend and free both the mirror and the test transaction. The system automatically establishes an abend trap for all abends that occurred on the terminal in region AOR1. When completed, request a dump from the Exit Session screen.

Repeat Step 8 as required for additional AORs. If your site is developing applications that make use of the Distributed Program Link DPL facility, you should intercommunicatiion the following information.

Installing and configuring intercommunication support There are different installation and configuration requirements depending on whether a CICS system is to participate in intersystem communication or multiregion operation.


This may overload the region and cause debugging sessions to be missed for the second and third guife masks. Local or remote traps may be used. They use file control commands, temporary-storage commands, and other functions in the same way.

Process global parameters XDGB xxxx. Enter XCB2 to run the test transaction. The actual transaction intercommubication may vary.

Recovery and restart in an intersystem environment This topic tells you what CICS can do if things go wrong in an intercommunication environment, and what you can do to help. Use the second intercommknication as described below to establish all breakpoints and traps in back-end transactions. If global traps are set for back-end transactions in multiple regions, exit to CICS after setting breakpoints, traps, etc.

CICS Intercommunication

Information Feedback Last updated: For example, entering the following Xpediter transaction:. It is intended for system programmers, application designers, application developers, and technical support staff. It is convenient to stay on the List Abends screen 1. Because the same terminal cannot always be used for the server program, it is impossible to predict the terminal ID.

intercommunicatuon Receiving Service Providers immediately delete information pertaining to regions, sessions, and routing masks that were local to the Service Provider shutting down. At this point, the system allows single-stepping, resuming, and other available functions. The steps below simplify the task of initiating Xpediter sessions in multiple AORs. This may also prevent execution of Xpediter transactions.


This will result in the missing of debugging sessions for the third trap mask. You can also stay on the List Abends screen 1.

6.1 Recovery and restart in interconnected systems

Enter the test transaction name TST1 to run the test transaction. Asynchronous processing Asynchronous processing distributes the processing required by an application between intercommunicating systems.

Performance in an intersystem environment This topic gives advice on improving aspects of CICS performance in a multi-system environment. The second abend trap is of little use, and it can lead to the false conclusion that a second terminal abend has occurred.

Setting these breakpoints or traps can cause the terminal to hang if it is busy with the test transaction.

When the Service Providers involved in a given CICSPlex are connected to each other, all region, session, and routing mask information is shared among them. Assuming that the client program is associated with a terminal, use that terminal to observe events in the intwrcommunication transaction.
