Have a job non-executable (NOEX) during specific times of each day it is set to run or by SCHID.
Jobs can be made non-executable on the DB.1 screen setting the EXEC field to N.
Non-executable jobs are used for many different reasons, one of which could be as a control job that triggers many others. The DB.1 EXEC setting is for all runs of a job at any time.
If you want to make a job non-executable only during specific times of any day it is scheduled to run, you can include the following in the job's JCL (position within the JCL is not important, but as a best practice you should put these right after the job statement(s)):
#JI,OB=hhmm,OA=hhmm,CV=CU
#NOX
#JEND
The OB and OA would be clock time for the beginning time and ending time that the job should come into the queue in non-executable mode.
You can also use:
#JI,ID=nnn
#NOX
#JEND
where nnn is the SCHID of the job that should be non-executable.
