Viewing system initialization (SIT) parameters

You can use CICS Explorer® to discover and view information about system initialization (SIT) parameters and SIT overrides.

Before you begin

CICS Explorer shows only the SIT parameters in a CICS® TS version 4.1 or later region. However if you have installed CICS Deployment Assistant you can also view some SIT parameters for CICS TS version 3.2 and version 3.1 regions.

A CICS TS version 4.1 region must have the following APARs applied:

CICSPlex® SM V4 APAR PM15214 .
CICS TS V4 APAR PM15583 .

The CICS JCL must also have MSGLEVEL set to 1 so that the SIT parameters are shown in the JCL output.

About this task

Using the CICS Explorer you can retrieve system initialization table parameters, system initialization table overrides, or a combination of both. You cannot, however, retrieve changes in the values of parameters that were made after startup using system programming interface commands.

Complete the following steps to retrieve information about system initialization parameters and their overrides.

Procedure

In the Regions view right-click a CICS region and hover over Show SIT Parameters
Click one of the following values:
- Combined: Combination of the original system initialization table definitions and any applied parameter overrides.
- Console: Override parameters as specified at startup on the system console.
- JCL: Override parameters provided through a JCL EXEC statement.
- SYSIN: Override parameters from the startup job stream defined in the SYSIN data set.
- Table: The original system initialization table values extracted from the DFHSITxx load module

Results

The system initialization parameters for the selected CICS region are shown in the SIT Parameters editor where they can be viewed.

A screen capture of the SIT Parameters editor. The Tab name, SIT Parameters (Combined), shows that the combined value was chosen.

If you have CICS DA installed you can right-click a CICS region in the system model and click Show SIT Parameters. If the region is a CICS TS version 3.2 or version 3.1 region you can only choose to show only the SYSIN and JCL parameters.
