CA Dynam for VSE User Guide

Using Other Software with CA Dynam/T
LIBR Backups and Restores
With TAPEL= Parameter
VSE Version 3 and higher support standard label tapes for backup and restore.
With RESTORE=ONLINE, no special CA Dynam processing is required. With
RESTORE=STANDALONE, LIBR performs pre-OPEN processing. The following is
an example of the necessary job control:
// JOB BACKUP STANDALONE
// TLBL BACKUP,'LIBR.BACKUP',0,,,,,08
// EXEC TDYNASN,SIZE=128K
ASSGN BACKUP,SYS006,OUTPUT
/*
// ASSGN SYS010,SYS006 */ SAVE TAPE ADDRESS FOR MTC RUN */
// EXEC LIBR
BACKUP LIB=IJSYSRS TAPE=SYS006 RESTORE=STANDALONE TAPEL=BACKUP
/*
// MTC RUN,SYS010
/&
Note: The Dynam/T HOLD option must be specified, because LIBR will access
the tape drive after close. If the tape drive was dynamically attached by either
the DYNT/VM or 3494 interface, it will not be automatically detached at close
because of the HOLD option. After the LIBR job completes, run a TDYNASN
DETACH job to detach any dynamically attached tape drive.
The following is for VSE/ESA Version 2 users only.
When running VSE/ESA Version 2 (VSE/ESA), output tapes are created in a
nonstandard organization by the LIBR program's BACKUP, RESTORE
commands, or both. The structure of these tapes is as follows:
STANDALONE PHASES
IF PRESENT
HEADER LIBRARY MEMBER
IF PRESENT
******** TAPE MARK #1 *********
LIBR BFID RECORD
HISTORY FILE IF PRESENT
******** TAPE MARK #2 *********
LIBR FHDR RECORD -
LIBRARY DATA RECORDS
LIBR EOBF RECORDS

multiple occurrences if more than
one (sub)library is processed
