MCATALOG
Use the MCATALOG command to specify that a tape dataset can be accessed by more than
one dataset name. The new dataset names are known as MCAT aliases. After a version has
been MCATALOGed, it is accessible by both its original dataset name and its MCAT
alias(es). The dataset is retained until all retention criteria from all associated BIM-EPIC
dataset definitions (EDDs) have been satisfied. MCATALOG can be used to create special
retention for a tape version. Subdatasets cannot be MCATALOGed. When a display of an
MCATALOGed version is requested by volume serial number, the original dataset record is
displayed.

Parameter Required? Valid Entry Default
from-dataset-name
Yes 1 to 44 characters None
One of the following two must be specified:
from-ver
1 to 999 None
from-ser
1 to 6 characters None
to-dataset-name
Yes 1 to 44 character None
to-ver
No 1 to 999 1
MCAT parameters are positional.
from-dataset-name specifies the name of the original dataset.
You must specify either SER or VER:
from-ver specify the version number of the original dataset.
from-ser specify the volume serial number of the first (or only) volume of the original
dataset.
to-dataset-name specifies the MCAT alias.
to-ver specifies the version number of the MCAT alias.
Make version 2 of the PAYROLL.MASTER dataset to be also version 1 of the
PAYROLL.PERM dataset, so it can be accessed using either dataset name.
