Giving the APPC and ASCH Started Procedures Access to Resources

Before you can start APPC and the APPC/MVS transaction scheduler (ASCH), the APPC and ASCH started procedures must have read-only access to the parmlib concatenation.

Your installation probably limits access to the parmlib concatenation to only authorized users. If so, you must refer to security product documentation for protecting and authorizing started procedures. If your installation uses RACF®, see z/OS Security Server RACF Security Administrator's Guide for information about giving read access to the APPC and ASCH started procedures.

Although your installation might also limit access to TP profile and side information data sets, you do not have to explicitly authorize the APPC and ASCH procedures to access those data sets. Because the APPC and ASCH started procedures reside in an authorized library, no additional security authorization is required for them to access TP profiles and side information.

The rest of this chapter describes the APPC/MVS security mechanisms, starting with a brief review of cooperative processing and its security implications.
