Cataloging Datasets Automatically
Description If the new dataset and version are to be controlled, they must have an
entry in the DSN Catalog. Dataset entries and version entries can be
created automatically for uncontrolled datasets using AUTOCAT and
AUTOLOG. In addition, dataset entries and version entries can be created
automatically using the DD statement parameter DISP=(x,CATLG).
AUTOCAT and AUTOLOG operate globally on all qualifying datasets.
DISP=(x,CATLG) operates locally on the dataset specified in the DD
statement. AUTOCAT and AUTOLOG are independent but perform
parallel functions using the same rules. However, there is an important
functional difference between them. AUTOCAT catalogs uncontrolled
output tape datasets and versions. AUTOLOG catalogs uncontrolled input
tape datasets only; versions are not cataloged.
See the BIM-EPIC Installation and System Guide for additional
information on AUTOCAT and AUTOLOG. See Chapter 6, “
BIM-EPIC
DD Statement,” for additional information on the DISP=(x,CATLG)
parameter.
AUTOCAT AUTOCAT creates a dataset definition for an output dataset if that dataset
is not in the DSN Catalog. All subsequent versions created under the
dataset name will be cataloged also, including the version that triggered
the AUTOCAT operation.
When automatically cataloging multi-dataset groups that are read out of
sequence, verify that the prime dataset is entered in the DSN Catalog
before reading any subdataset in the group. If the prime dataset is read
first and the datasets are read in sequence, this requirement is satisfied.
The following fields are entered in each autocataloged dataset definition.

Datasets that are automatically cataloged are identified by a user ID and
given the comment **** AUTO CATALOGUE **** when shown on
reports and displays. The user ID is AC. All automatically cataloged
datasets are generation datasets. These dataset definitions can be changed
later using Online Manager or TSIDMNT.
