Description

You can specify a condition code value with which the CA 11 WA step - U11RMS terminates in order to conditionally execute a recovery step in a job. This might be useful in the event a restore of a database is needed upon a restart.

Solution

This procedure provides the steps necessary for conditionally executing a recovery step.

Step1 executes the U11RMS program. Notice that STEP4 is a VSAM update step. Therefore, if STEP4 ABENDS the recovery of the master file would be needed from STEP3. Also notice that STEP3 has a CONDITION that indicates do not executes unless STEP1 completes with a COND=03. Now, during the production run if STEP1 completes with a COND=0, STEP3 will be skipped and if STEP4 should ABEND, the job will be set to restart in STEP2. This is because the CMT reflects STEP3 as a NOEX step.

To restart the job, you have to override STEP2 and code STEP3 as the restart step. Also, you will need to pass a CC=03 from the RMS step, in this case to STEP3, so that CA 11 WA can force a restart in STEP3. This is normally done through a formatted screen from your respective Job Management or Workload Automation engine (CA 7 WA, CA Scheduler JM, and CA Jobtrac JM), but the example demonstrates what is actually executed in the JCL.

Note: the CA11NR DD Dummy statement prevents restarting in a non restartable step.

  Production Run:
  //STEP1   EXEC  U11RMS,TYPRUN='P' 
  //STEP2   EXEC  PGM=USERPGM1 
  //STEP3   EXEC  PGM=RECOVER,COND=(03,NE,STEP1) 
  //STEP4   EXEC  PGM=UPDATE 
  //CA11NR  DD DUMMY 
  //STEP5   EXEC  PGM=USERPGM2 
  //STEP6   EXEC  PGM=USERPGM3 
  Restart:                
  //STEP1   EXEC  U11RMS,TYPRUN='R,STEP3,CC=03' 
  //STEP2   EXEC  PGM=USERPGM1 
  //STEP3   EXEC  PGM=RECOVER,COND=(03,NE,STEP1)   
  //STEP4   EXEC  PGM=UPDATE 
  //STEP5   EXEC  PGM=USERPGM2 
  //STEP6   EXEC  PGM=USERPGM3
