Example of Action Selection

This example shows the state mismatch action selection. Some columns were omitted for clarity.

NAME       CURRENT_STATE DESIRED_STATE ACTMODE TYPE
  RES1     DOWN          UP                    STC
  RES2     DOWN          UP                    STC
  RES3     DOWN          UP            BOUNCE  STC
  RES4     STARTING      UP                    STC

Following is an example of the actions that were selected in response to the above state mismatch:

    ACTION_PROCESS ACTION_CURRENT ACTION_DESIRED ACTION_MODE ACTION_RES_TYPE ACTION_TEXT
  1 ACTION         DOWN           UP                                         MVSCMD("START &JOBNAME")
  2 ACTION         DOWN           UP                         RES2            MVSCMD("S DJOB,PARM='IPL'")
  3 ACTION         DOWN                          BOUNCE                      TSOCMD("OI BOUNCE")
  4 ACTION         DOWN           UP             BOUNCE                      TSOCMD("OI REBOUNCE")
  5 ACTION         STARTING       UP                                         SETCOL("CURRENT_STATE,DOWN")

In the previous example, the following actions are taken in response to the resource state change events:

• For RES1-Action 1 is selected with a score of 16. Action 5 is not considered for this resource because the current state does not match the ACTION_CURRENT column of the action table. Actions 2, 3, and 4 are bypassed because there are non-null columns in the action table that do not match the resource.
• For RES2-Action 2 is selected with a score of 18. Action 1 also matches the resource; however, its score is 16. Actions 3 and 4 are rejected because the ACTION_MODE column is non-null and it does not match the resource. Action 5 is not even considered because the current state does not match the value of the ACTION_CURRENT column of the action table.
• For RES3-Action 4 is selected with a score of 24. Actions 1 and 3 are also matches with scores of 16 and 8 respectively.
• For RES4-Action 5 is selected with a score of 16. No other actions are considered.
