CWAKEY
The CWAKEY system initialization parameter specifies the storage key for the common work area (CWA) if you are operating CICS with storage protection (STGPROT=YES).
- CWAKEY={USER|CICS}
- You specify how much storage you want for the CWA on the WRKAREA parameter.
The permitted values are USER (the default), or CICS:
- USER
- CICS obtains storage for the CWA in user key. This allows a user program executing in any key to modify the CWA.
- CICS
- CICS obtains storage for the CWA in CICS key. This means that only programs executing in CICS key can modify the CWA, and user-key programs have read-only access.
If CICS is running without storage protection, the CWAKEY parameter is ignored, and the CWA is always allocated from CICS-key storage.
