Using SSM Global Application › Verification and Diagnostic Commands

Verification and Diagnostic Commands

Several ISPF primary commands for detecting SSMGA configuration and runtime errors are available in the OPSVIEW 4.11.G SSMGA resource monitor. These commands detect the most common errors in SSMGA and in a few cases repair them automatically. When new SSMGA tables are added to the configuration, to insure a valid configuration all of these commands should be executed in order.

VERSYS command (Rexx program: SSMGAPH1):

• Validates the local system SSMGA required parameter settings
• Checks for MSF connections to an SSMGA global system
• Checks for required tables and their column structures
• Checks SSMGA resource column values for syntax, contents, and consistency
• Verifies that required rules are enabled
• Checks action table columns for the SSMGA required actions
• For some parameter and table errors the proper SSMGA value is set

VERGBL command (Rexx program: SSMGAPH2):

• Verifies that all SSM resource table rows on accessible systems in the SSMplex have corresponding resource rows in the local LST and in the GST
• Detects rows in the LST and GST that do not have corresponding SSM resource rows

VERMOV (Rexx program: SSMGAPH3:

• Diagnoses problems with movable resources
• Identifies any outstanding SSMGA WTORs that require a response
• Verifies that a specific movable resource has the same primary system name on all systems
• Verifies that movable resources exist on systems that are consistent with their primary and alternate system definitions
• Identifies movable resources that are not assigned to a system or are waiting for a particular system that is not active
• Evaluates the current and desired system in light of the action mode and move mode for consistency on all systems

About SSMGAV2

The System State Manager Global Application Version 2 (SSMGAV2) uses some basic features of CA OPS/MVS SYSPLEX capabilities, SSM, and a new REXX-coded application to implement monitoring and control of operations that span multiple systems in a SYSPLEX.

SSMGAV2 uses the SYSPLEX features to remove the MSF dependency, global system concept, and data replication that SSMGA needs.

SSMGAV2 lets you perform the following tasks:

• Apply cross-system prerequisite and subrequisite to resource status determination.
• Move a resource, or group of resources, from one processor to another with minimum transition time.
• Monitor the status of resources from multiple systems on a single, integrated ISPF display.
• Display and control SSMGAV2 from an operator console or automation procedure by using a command rule.
• Restore the operation of a resource automatically, when its preferred host fails, by restarting the resource on an alternate host.

How SSMGAV2 Works

CA OPS/MVS SYSPLEX scope variables are maintained to store data of moveable resources. This storage replaces the need for a Global Status Table.

• Moves the resources when the SSM#DESSYS value is updated.
• Processes the SSMGAV2 commands that the GAV2CMD command rule generates to move and display moveable resources.
