SSMGA requires several new columns in SSM resource tables to support the functionality that SSMGA provides. Use REXX program OPSSM2CV to add the required SSMGA columns to SSM resource tables by specifying a parameter of SSMGA(Y).
Strictly local resources that cannot be moved to another system do not require any column changes. Defaults for non-existent columns are supplied for the LST and GST tables.
All system name values in SSMGA are in the form:
sysname.subsys
Specifies the real z/OS system name.
Specifies the OPS/MVS subsystem name on the system (usually OPSS).
Movable resources require the following new columns:
PRIMARY_SYSTEM CHAR(14) UPPER CASE DEFAULT('*.*') SSM#CURSYS CHAR(14) UPPER_CASE DEFAULT('*.*') SSM#DESSYS CHAR(14) UPPER CASE DEFAULT('*.*') SSM#MOVMOD CHAR(8) UPPER CASE DEFAULT('INACTIVE') SSM#SYSLST VARCHAR(350) UPPER CASE SSM#GRPLST VARCHAR(350) UPPER CASE AUTOHOME CHAR(1) UPPER CASE DEFAULT('N')
The following list describes the new columns:
Specifies the preferred system to run the resource and is also the constant cross-system prereq specification name for resources that use the movable resource as a prerequisite but do not have a local SSM replicated copy of the movable resource. Even when the movable resource is running on an alternate system, the primary system name is still the cross-system prerequisite name; that is, system.subsys.table.name.
Contains the current system that owns the resource.
Specifies the system name to which the resource should be moved. Changing the desired system to an alternate system name on the current system copy of the resource causes the resource to stop on the current system and move to the alternate system.
Controls how the current system is selected. A value other than INACTIVE indicates that the resource is movable from the primary system to any other system specified in the SSM#SYSLST column. The alternate systems are specified as word or comma delimited list. System names are in sysname.subsys format. The sequence of alternate system names in the list is an implied priority of alternate systems for automatic selection of an alternate system.
SSMGA recognizes three special values for SSM#MOVMOD:
Any other value of move mode allows movement of resources by manually changing the desired system to an alternate system.
Lists all of the available alternate systems to which you can move data.
Specifies SSM resources, such as a workload, global status, or disaster recovery eligibility, using arbitrary 1-18 character names. The ISPF monitoring tool uses the group names in SSMGA to move groups of resources and in the operator command facility for query and action commands. The list of group names is word or comma delimited. SSMGA monitors the resource group name list for changes
Specifies the Yes/No value that determines if the resource can move back to its home system once this system becomes active.
