If you plan to use VSAM RLS to enable CICS® regions to share VSAM data sets, carry
out the following steps:
- Define the master coupling facility lock structure.
- Define coupling facility cache structures and cache sets.
- Define SMS storage classes for RLS access.
- Alter data set characteristics, if necessary, to make data sets eligible
for RLS access.
- Define sharing control data sets.
- Establish new authorization that is required by the VSAM RLS support.
- Add new parameters to SYS1.PARMLIB.
- Establish new procedures for VSAM RLS support.
- Activate the coupling facility structures.
An overview of each of these steps follows.
