Requirements for sysplex support

If your installation plans to use sysplex support (running multiple independent instances of PKI Services, one per image, that work in unison):

If you are using VSAM data sets for the object store and ICL, all systems in the sysplex that run PKI Services must have the same release of z/OS® installed, and all instances of PKI Services must share the same VSAM data sets. To do so, they use VSAM record-level sharing (RLS). This requires setting up a coupling facility for data sharing (lock and cache).
If you are using DB2® tables for the object store and ICL, all systems in the sysplex that run PKI Services must be at z/OS V1R13 or later and have DB2 Version 9 installed, and the DB2 subsystems that share data must belong to a DB2 data sharing group that runs on a sysplex cluster.

See (Optional) preliminary steps for establishing VSAM RLS for information about creating VSAM data sets suitable for VSAM RLS. For information on establishing a Parallel Sysplex® environment with a coupling facility, see z/OS MVS Programming: Sysplex Services Guide. For more information about establishing data sharing for VSAM RLS, see z/OS DFSMS Introduction and z/OS DFSMSdfp Storage Administration.
