Hi,

Many of our Jobs create Temprorary Flat files, like in Intermediate Sort steps, we need these files for debuging so these are created in DASD. But since these will not be needed after our next run, these needs to be deleted before our next run. Instead of having a Dummy step that deletes these files, I heard we have a feature in CA7 which does this automatically. Can any one share those features?

If I remember correctly, it's a step (PROC) entitled UCC11 or CA11 and is placed at the start of the production JCL. It deletes all data sets that are defined in your job as DISP=(NEW,CATLG). Usually the systems programmers take care of that for you.

Why not delete them at the end of the batch job. That way the space is freed up immediately and available for other jobs to use, and also reduces the chances of Sx37 abends.

As expat says, deleting them at the end of the job WILL free up DASD sooner. The downside is that rerunning a portion of a successfully completed job (yes, sometimes that's desireable) becomes more difficult. In either case, shops that have CA-7 will nearly always include the CA-11 step at the beginning of a production job stream. After all, it can't hurt to try to delete a non-existent file.
