Defining a CICS VR prefix

Start of change When the CICS® VR server address space activates, it attempts to allocate the CICS VR message, trace and dump data sets using a predefined naming convention. End of change

This value is also used as the high level qualifier, and optional second level qualifier by CICS VR when it is notified of DFSMSdss logical copies and when creating CICS VR change accumulation data sets. The first level qualifier and optional second level qualifier of this predefined naming convention is taken from the value specified in the CICSVR_DSNAME_PREFIX parameter.

Prior to activating the CICS VR server address space, you must specify the following parameter in the active IGDSMSxx member of SYS1.PARMLIB.
CICSVR_DSNAME_PREFIX(hlq.slq)
Start of change Where hlq.slq specifies the first level qualifier, and optional second level qualifier that CICS VR must use in the naming convention for the CICS VR message, trace and dump data sets, DFSMSdss logical copies, and change accumulation data sets. DWW is the default value.

See Understanding the DWWMSGA, DWWMSGB, DWWDMSG, and DWWDUMP data sets naming convention for more information.
