You can use CICS Explorer to discover and view information about system initialization (SIT) parameters and SIT overrides.
CICS Explorer shows only the SIT parameters in a CICS version 4.1 or later region. However if you have installed CICS Deployment Assistant you can also view some SIT parameters for CICS version 3.2 and version 3.1 regions.
The CICS JCL must also have MSGLEVEL set to 1 so that the SIT parameters are shown in the JCL output.
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.
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 version 3.2 or version 3.1 region you can only choose to show only the SYSIN and JCL parameters.
