Using LIBR BACKUP/RESTORE Commands
Description You can use BIM-EPIC to control the tape datasets created by the LIBR
BACKUP command and read by the LIBR RESTORE command.
DSN Catalog Only prime dataset definitions are allowed. Therefore, multi-dataset tape
groups are specifically disallowed.
JCL
Requirements
There are several JCL requirements you must consider.
Each controlled dataset must be defined with a TLBL statement
or DD statement.
LUB allocation must be inhibited since LIBR requires the SYS
number specified in BACKUP or RESTORE. In addition, the
tape drive assignment must be held after the dataset is closed
since LIBR may attempt to access the tape drive even after the
close has been completed.
When including the standalone restore programs,
RESTORE=STANDALONE, in BACKUP, use the TSIDASS
OPEN function to allocate the first tape output volume before
performing the // EXEC LIBR BACKUP.
LIBR Control
Statements
Use TAPELABEL parameter to specify a filename consisting of one to
seven alphanumeric characters. This is the same filename used in the
accompanying TLBL statement or DD statement.
Restrictions Due to LIBR restrictions, you cannot use GDI to route a tape backup to
disk.
Examples Many sample job streams for LIBR BACKUP and RESTORE are
supplied when BIM-EPIC is installed. See the BIM-EPIC Installation and
System Guide for additional information.
