Using System State Manager › How SSM Works › Resource Tables

Resource Tables

Resource tables store information about the status of each resource. You could place data on all of your system resources in a single table. However, we recommend that you create a separate resource table for each type of resource. For example, you create a table for VTAM nodes, another table describing printers, and so on.

The following resource table named STCTBL shows a subsystem resource table as viewed in the CA OPS/MVS table editor. When column definitions extend past the right margin of your terminal screen, issue RIGHT commands or you press the PF11 key to display more of the columnar data.

The descriptions of the columns in the STCTBL resource table are as follows:

NAME

Identifies the name of the resource, such as JES2 or VTAM. This resource name is usually the job name of the subsystem.

CURRENT_STATE

Indicates the actual state of the subsystem.

DESIRED_STATE

Indicates the preferred state of the subsystem.

MODE

Indicates the way that SSM monitors and controls the subsystem.

PREMODE

Specifies a setting that controls whether prerequisites and subrequisites are processed for the resource when the desired state of a resource is UP and the current state is DOWN, or the desired state is DOWN and the current state is UP.

Note: Setting both PREMODE='INACTIVE' and REFMODE='INACTIVE' disconnects the current resource from any prerequisite or subrequisite processing.

REFMODE

Specifies a setting that controls whether the current resource permits other resources to reference the state of the current resource for purposes of prerequisite and subrequisite processing.

Note: Setting both PREMODE='INACTIVE' and REFMODE='INACTIVE' disconnects the current resource from any prerequisite or subrequisite processing.

ACTMODE

Displays an extra mode value that can temporarily override the resource processing mode or be used to execute different actions for the same state combinations. A change in the value of the ACTMODE column of a resource causes the resource to be selected for processing, regardless of the values of its current and desired state.

The ACTMODE column is compared to the ACTION_MODE column in the action table during the select action procedure.

Note: For more information on the select action procedure, see How SSM Decides What Action to Take.

SCHED_MODE

(Optional) If the value of this column is INACTIVE, then Schedule Manager RESET processing bypasses any updates to the DESIRED_STATE column of this resource.

Note: For more information on this schedule override feature, see Using Schedule Manager.

JOBNAME

Specifies the job name for the subsystem.

TYPE

Identifies the type of subsystem, for example, IMS, CICS, or VTAM.

CHKPOINT_STATE

Same as the value for DESIRED_STATE. The CHKPOINT_STATE column provides one way to reset desired resource states after a restart of CA OPS/MVS.

IPL_STATE

Displays the state in which the subsystem follows an IPL.

TNGNOTIFY

(Optional) Determines whether the resource is displayed as an icon on the CA map that the CA Event Manager product creates to monitor SSM resources.

RESOURCE_TEXT

(Optional) Contains documentation for the SSM resource. This information displays on the CA Network and System Management System Status Manager CA OPS/MVS Option workstation. You can use this column to display the text of the last z/OS message that has changed the state of the resource.

PREREQ

Displays a list of resources that must be in an UP state before SSM can start the subsystem.

Maximum Length: 1000 characters

MISSING_PREREQ

Displays a list of the prerequisite resources that have not been satisfied. A VARCHAR definition is used to conserve memory.

Maximum Length: 1000 characters

PREV_STATE

Tells SSM whether the state of a subsystem has changed.

INTERNAL_DATA1

Contains data that SSM uses internally to control the subsystem.

PRIMARY_SYSTEM

(Optional) If present, the contents of this column sets the variable SSM!PRISYS.
