Job Scheduling

Post by Bilwakunj »

Hi,
Can anyone help me out to know why Autosys is used for the job scheduling if that can be done using director? You can use UNIX script for scheduling also. Then what is the difference? In what scnerio you shd go for director, autosys or unix script?

Thanks in advance!!

You've posted in the wrong forum.

To answer your question, the difference between cron and an enterprise scheduler are vast. You need to research tools like Autosys, Tivoli, etc and understand what those products do. cron is to a shovel what an enterprise scheduler is to an earth mover.

Before some of the new features in DataStage these tools would ftp a file, wait for it to finish, start a DataStage job, wait for it to finish and then ftp the new DataStage file to some other machine. That is still not too easy in DataStage without a shell script. These tools are great at coordinating interaction between products like DataStage and other processes. They are very powerful.

Sometimes they are overkill. If all you need can be done in DataStage then use cron.
