RLS access implications
The supplied installation samples specify non-RLS access for the CICSĀ® Configuration Manager files. If you change to RLS access, there are rollback (EXEC CICS SYNCPOINT ROLLBACK) implications for the following files:
- CCVDDD repository file
- CCVJNL journal file
- CCVPT1 journal file alternative index path
- CCVPT2 journal file alternative index path
If you want to implement RLS management, be aware of the following requirements:
- The SMS options for the data set type must be RLS-enabled on the LPAR that runs the CICS Configuration Manager server.
- DFSMS Transactional VSAM Services (DFSMStvs) must be enabled and configured on the LPAR that runs the CICS Configuration Manager server.
- The CICS region must specify the SIT parameter RLS=YES for the region running the CICS Configuration Manager server.
- To enable rollback, the VSAM CLUSTER definition for the files must specify LOG(UNDO) or LOG(ALL)
with a LOGSTREAMID:
- For CCVDDD, refer to SCCVSAMP sample members CCVXDDD and CCVXBKUP.
- For CCVJNL, refer to SCCVSAMP sample members CCVXSYSO, CCVXBKUP, and CCVX0003.
- The CICS resource definitions for the following files
must specify RLSACCESS(YES). Refer to SCCVSAMP sample member CCVXCSD for the file definitions:
- CCVDDD
- CCVJNL
- CCVPT1
- CCVPT2
For more details, see the z\OS documentation about VSAM record-level sharing.
