Uncontrolled Datasets
Description Any dataset that is not controlled using the DSN Catalog or Start Track 1
is called an uncontrolled dataset. With a few exceptions, uncontrolled
datasets are not provided with any additional features than are available
when using standard VSE JCL.
For uncontrolled tape datasets, BIM-EPIC provides protection for all
output tapes to ensure that any tape with an active status in the BIM-EPIC
Catalog is not used. Additionally, if the configuration option
UNCTL=NO is set, uncontrolled tape datasets cannot use any tape in the
DSN Catalog, even if the tape has a scratch status. VSE ASSGN
statements are not required for uncontrolled tape datasets. If there is no
assignment, the operator is prompted to specify an available tape drive to
use and BIM-EPIC will make the appropriate assignment. Unlike
controlled tape datasets, the assignment is not released at close unless the
configuration option UNCTAP=YES is set.
Uncontrolled disk datasets can be placed within the disk pool extents if
the datasets are created with adequate retention. ASSGN and EXTENT
statements are normally required but if the configuration option
UNCDSK=YES, the ASSGN statement is optional.
JCL
Requirements
No special options are required for uncontrolled datasets.
