First let us start with dispelling a common myth, The InfoSphere scheduler is not an Enterprise Scheduler application.
The scheduling service in InfoSphere leverages the operating system (OS) scheduler, in the case of Linux, this is CRON, and provides graphical User Interface, which a provides time-based capability to schedule Jobs at the Suite component level. The Director Client scheduler can:
Schedule individual jobs and sequence jobs
Schedule Jobs/Sequencers to run:
How to set-up the Daily Schedule
Steps to set the Daily Schedule are below:
Open the DataStage Director
Once the browser is open click on Job>Add to Schedule
Click “Daily” under the “Run Job” and choose the time
This is a quick, easy, shortcut way to schedule an InfoSphere DataStage job in Linux crontab to take advantage of capabilities within crontab not available in the InfoSphere graphical user interface (GUI).
For this example, the job has been adjusted from the stand InfoSphere scheduler graphical user interface (GUI) setting to run every 15 minutes, which is not available in the GUI.
The Basic crontab Scheduling Process
Schedule the job in DataStage Director
Login into Linux as the user, who created the schedule
Run ‘crontab -e’ command
Edit crontab command line using VI commands
Note: The revised schedule if different from the InfoSphere scheduler GUI standard setting will not display as changed in the GUI. However, the jobs will run as scheduled, if edited correctly, and can be verified in the Director Client.
