Is JCL really useful?

Postby ramesh4mainframes » Wed Jun 16, 2010 9:54 am

By using ISPF panel we can create dataset, delete, copy the members, copy the data........ etc. Whatever the functionality avail in JCL almost all will be can done by using ISPF....
So, my doubt is ISPF is user friendly then why should have to go for JCL?

Thanks,

ISPF requires someone sitting at a terminal. JCL jobs can execute in the middle of the night when there is nobody at the terminal.
ISPF cannot handle the millions of records in a normal production environment -- JCL jobs can.
ISPF cannot be scheduled to start at 7 PM when the CICS region comes down. JCL jobs can be scheduled.
