Hello,

Many organizations use something other than idcams for performance reasons.

What's the difference between EMC Snap utilty and IDCAMS utility .. Both are used to copy the data !!

IDCMAS not just do "copy", it does many other things; comparing one feacture of it with EMC Snap does not sound fair.

As Dick indicates, many organisations use, sometimes, some in-house written programs as well for COPY. Copying files is not a high-CPU operation. It depends more upon the I/O and you might reduce the EXCP count by some factor by using even Sort over IDCAMS....

Personally, I'd believe, it is highly influnced by who-are-in-position-of-taking-decision when such desicions of using utilities are made...

If you are referring to the SNAPSHOT facility, then the first difference is that IDCAMS is used for a variety of things (copying files, defining VSAM files, altering GDG and file characteristics, working with catalogs, and so forth) whereas SNAPSHOT makes point-in-time backups of data sets but does none of the other things IDCAMS can do. A SNAPSHOT will be much quicker than a full backup but cannot be used away from the storage device.

Got it ... Thanks Anuj, Dick & Robert !!

You're welcome, Good Luck!
