RD Parameter
RD Parameter
Note!
RD parameter can be coded at the job level as well as step level.
RD stands for restart definition. RD parameter used to -
- Allow JES to perform an automatic job restart after the job failure.
- Allow the operator to perform an automatic job or a checkpoint restart if a job fails.
RD is a keyword parameter and is optional.
Syntax -
RD={R }
{RNC}
{NR }
{NC }
R | Specifies restart, checkpoints. The operator can perform an automatic restart if the job or step fails. |
RNC | Specifies restart, no checkpoints. The operator can perform an automatic restart if the job or step fails. |
NR | Specifies no restart, checkpoints. The operator can't perform an automatic restart if the job or step fails. |
NC | Specifies no restart, no checkpoints. The operator can't perform an automatic restart if the job or step fails. |
Default and overrides -
- If no RD parameter is coded, the system uses installation default.
- If the RD parameter is coded at job and step level, the job RD parameter overrides the step RD parameter.
Examples -
Scenario - For automatic restart.
//MTHEXMP1 JOB (META007),'PAWAN Y',RD=R
RD=R specifies that the operator can perform automatic restart if the job fails.
