To enable the CICS® VR server address space, these
are the requirements that must be met.
- The CICS VR linklist libraries, SDWWLOAD
and SDWWLENU (or SDWWLJPN, if JCCV51K is installed) must be included
in the MVS™ LNKLST concatenation and must be defined
as APF-authorized libraries.
- All systems must be running as a sysplex; local mode is not allowed.
- The CICS VR recovery control data sets
(RCDSs) must be created, one is required, but three are recommended.
The RCDSs must be defined on storage that is shared by all systems
in a sysplex that belong to the same CICS VR
XCF group.
Two CICS VR message data sets must
be defined, and the CICS VR trace and dump data sets
must be defined. CICS VR can dynamically create
and allocate these data sets during system initialization if SMS-managed
storage is available.
- SMS must be active.
- Required parameters must be specified in the active IGDSMSxx member
of SYS1.PARMLIB.
