BIM-EPIC Dataset Definitions
BIM-EPIC Dataset Definition Components
Description The BIM-EPIC dataset definition (EDD) consists of several components.
The following sections describe each component.
Dataset Name BIM-EPIC uses the dataset name in the DSN Catalog to identify a dataset
as a controlled dataset. Each time a controlled dataset is opened or closed,
BIM-EPIC participates in the processing of the dataset.
The rules for dataset naming are:
Non-generation dataset names can be up to 44 characters long.
Generation dataset names can be up to 35 characters long.
Special considerations apply to tape datasets that belong to a multi-dataset
group. See “
Prime Dataset Name” for additional information.
Comment You can include one 30-character comment with any BIM-EPIC dataset
definition. Comments provide additional documentation for the dataset
and are printed in BIM-EPIC reports.
Passwords Passwords protect datasets and their associated versions against
unauthorized uses of RELEASE and UNLOCK. A password does not
LOCK, RELEASE, or UNLOCK the dataset. See Chapter 2, “
BIM-EPIC
Online Manager,” and Chapter 3, “TSIDMNT—DSN CATALOG
MANAGEMENT UTILITY,” for additional information on RELEASE
and UNLOCK.
Encryption
Password
Data encryption encodes tape datasets as they are written. The datasets
are decoded only when they are read using the same DSN Catalog that
was used to write them. Data encryption can be used to prevent tape
datasets from being read at external locations. However, data encryption
provides no protection against unauthorized internal use.
Entering an encryption password for a dataset invokes data encryption for
each tape version you create. You do not need to remember this password.
The encryption password and the dataset password function
independently of each other. You can use both passwords, if necessary.
