Reply with quote

I have one requirement to run multiple JCL parallel.
Suppose I have 4 JCLs. Now I want to submit all these four JCL parallel to save the process time.

Is there any way to submit all four JCLs through either a single JCL or some other way?

Yes. Remember that all must have different job names, else they will serialize regardless of submission method.

  1. If this is intended to be in the production environment, use the fine scheduler.
  2. If this is in the development or test environments, you may or may not have a useful scheduling system, or even any at all. However, you can:
    1. Submit a job that uses the utility of your choice to read the jobs (not "JCLs"; the two terms are not equivalent, and if you have JCL that is not a job, your task just became more difficult, although not impossible) and copy them to the internal reader.
    2. Use the TSO SUBMIT command multiple times; you will, my name as my word, be forgiven in the World to Come for the tiny amount of non-parallelism inherent in this.
    3. If the frequency of doing this justifies it (and it probably doesn't), you can write a few lines of Rexx to submit these jobs.

  3. Hi, Opal!

Best of luck in this endeavor.
