You can schedule jobs to be released from the job queue at a particular time, or you can use a job schedule entry to submit your job to the job queue automatically at the time you specify. Job scheduling allows you to control the date and time a batch job is submitted to or becomes eligible to start from a job queue. This flexibility can help you as you balance the work load on your system.">Job scheduling options</a></div>

<div><a href="rzaksajsmanage.htm" title="The Advanced Job Scheduler licensed program (5722-JS1) is a robust scheduler that allows unattended job processing 24 hours a day, 7 days a week.

<div><a href="rzaksjobscheduleentry.htm" title="If your system does not have the Management Central Scheduler or the Advanced Job Scheduler, you can still schedule jobs using a job schedule entry, which is accessed from the character-based interface.

<div><a href="rzakshowjobsrschdsbmjob.htm" title="This character-based interface command controls the time a job is released in the job queue.

<div><a href="rzaksjobschdlnsysavailable.htm" title="If the system is powered down or in restricted state when scheduled times are reached, jobs cannot be submitted from job schedule entries and the status of scheduled jobs cannot be changed.
