Move or Reallocate the Communications Data Set

If you are moving the communications data set to a different device type or enlarging it, reallocate and reformat instead of using IEBGENER.

The communications data set is pointed to by the UCC7CMDS DD in CA7ONL and in ICOM. You must have both down to reallocate or move the file. You can move the communications data set using utility IEBGENER. As a best practice, if you are moving the communications data set to a different device type or enlarging it, reallocate and reformat it. Do not copy using IEBGENER.

To reformat the communications data set, see member CA07N700 in JCLLIB.

If you are not copying the existing communications data set, stop job submission and let all active jobs complete.

Business Value:

This best practice results in less down time when reallocating files.
