Use RELDAYMON – help text:
The job is submitted on the specified day of the week
the first time it occurs in the month. For example,
if you specify SCDDAY(*TUE), FRQ(*MONTHLY) and
RELDAYMON(1), the job is submitted on the first
Tuesday of every month.
The basic job scheduler object doesn’t directly support ‘every other’ or ‘every 3rd’ week or similar intervals. Basic schedules work around daily, weekly and monthly intervals. A simple wrapper program as noted in discussion can be used to adjust to non-standard schedules.
For a non-programmed solution, the Advanced Job Scheduler product can be installed and licensed. An ‘every other week’ schedule could be set up as an ‘every 14 days’ scheduled job.
