Resource tables contain a list of resources and information about these resources, such as names, types, prerequisites, current and desired states, and previous states. The RDF can contain many different resource tables.
Each resource table is associated with one action table. Action tables contain action clauses that execute when a resource is not in its desired state. They tell SSM what to do to manage the resources. An action table can be associated with many resource tables, but each resource table can be associated with only one action table.
For an example of how resource and action tables work together, see the sample resource table and action table. These sample resource and action tables show that MIMGX has a current state value of DOWN and a desired state value of UP. SSM reads the action table and finds the row where the ACTION_PROCESS column value equals ACTION, the ACTION_CURRENT column value (DOWN) matches the CURRENT_STATE column value (also DOWN), and the ACTION_DESIRED column value (UP) matches the UP value in the DESIRED_STATE column.
Since none of the ACTION_RES_TYPE columns for DOWN to UP match the resource name or type of MIMGX, the default DOWN to UP action table row (the first row) is selected. This match causes SSM to perform the action in the ACTION_TEXT column of this row, which in this case issues a z/OS command to restart job MIMGX.
