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
Attempt to access the CSD file in RLS mode. If the attempt fails (the CSD file does not support RLS mode), then access the CSD file in non-RLS mode (as per the NOTRLS option, below). 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 using RLS services. If the attempt fails (the CSD file does not support RLS mode), then 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.
