ZOSMIGV1R11_RMM_DUPLICATE

Description:

This check is used to determine if an installation has changed the hard coded switches in EDGVREC load module which control VRSEL GDG processing, and to show them how to enable the same limit at z/OS® V1R11 and later releases using OPTION GDG.

This is a System REXX check, which means that it runs under the security assigned to the IBM® Health Checker for z/OS procedure, hzsproc. The RACF® user ID used for the System REXX check must have READ access to the LINKLIB library, and if AMASPZAP is under program control, the userid also needs READ access to AMASPZAP.

Reason for check:

The check is intended to identify when a migration action is needed when migrating from a release below z/OS V1R11.

z/OS releases the check applies to:

z/OS V1.9 and z/OS V1.10

Type of check (local, remote, or REXX):

REXX

User override of IBM values:

The following shows the default keywords for the check, which you can override on either a POLICY statement in the HZSPRMxx parmlib member or on a MODIFY command. This statement may be copied and modified to override the check defaults:

UPDATE
 CHECK(IBMRMM,ZOSMIGV1R11_RMM_DUPLICATE_GDG)
 INTERVAL(ONETIME)
 SEVERITY(MED)
 DATE('date_of_the_change')
 INACTIVE
 REASON('Your reason for making the update.')
 PARM('LINKLIB(SYS1.LINKLIB)')

Debug support:

Yes, additional information is written to REXXOUT data set.

Verbose support:

Yes, when also used with DEBUG, additional information is written to REXXOUT data set.

Parameters accepted:

An optional PARM('LINKLIB(linklib_dsname)') is supported. linklib_dsname is a fully qualified data set name, specified without quotes, where load modules targeted to the LINKLIB DDDEF name reside. The load module EDGVREC must be in this data set.

When no PARM is provided the check uses SYS1.LINKLIB.
