Defining CICS configurations that refer to CSD files
CSD files specified by CICSĀ® configurations must have a disposition of "shared" and cross-region share options of 2 or greater.
Before creating a CICS configuration that refers to a CSD file:
A CICS configuration that refers to a CSD file must specify one of the following record-level sharing (RLS) access options, to determine whether or not the CICS Configuration Manager server uses RLS mode to access the CSD file:
- DYNAMIC
- First, attempt to access the CSD file in RLS mode. If the CSD file does not support RLS mode, the attempt fails; access the CSD file in non-RLS mode. This DYNAMIC option is recommended, as it offers the most flexibility for accessing CSD files.
- NOTRLS
- Access the CSD file in non-RLS mode.
- RLS
- Attempt to access the CSD file in RLS mode. If the attempt fails, log the failure in the CCVLOG JES output for the server CICS region. Access to the CSD file fails.
If two or more CICS configurations refer to the same CSD file, then, when you change the RLS access option in any one of them, the server automatically applies the change to all of them. This ensures that no conflict in RLS access options can occur for a specific CSD file, avoiding CSD file access problems.
