Does JCL support Automatic start? If yes, then explain how. |
|
Answer» It is possible to restart JCL automatically through a predefined keyword parameter, such as RD (Restart definition) keyword. HOWEVER, this usually results in irregular program termination. RD ("restart definition") triggers the start of the job at the CHECKPOINT automatically. At various points of the job, CHECKPOINTS act as markers for the execution of the job. RD BEGINS by looking for the last successful checkpoint and STARTS from there. |
