SERIALIZE statement
When a step is flagged with the SERIALIZE statement, Job Optimizer runs the step only after all previous steps have been completed. Job Optimizer then waits for the serialized step to finish before running all future steps.
You can specify SERIALIZE at the step level.
Because JTL statements override User Control Facility (UCF) statements, you can use the SERIALIZE JTL statement to override a NOSERIALIZE statement in the UCF member.
The SERIALIZE statement does not affect the step that is being targeted to a specific image (with a TARGET JTL statement or a TARGET statement in the UCF member).
The SERIALIZE statement has the following syntax:
//*BSLCNTL SERIALIZE
