BRMS can assist you in the recovery of journaled libraries, files,
and members by recovering the associated journal if it does not exist
on the system, recovering the corresponding journal receivers, and
applying the journaled changes.
Note:
BRMS will use Recovery device *MEDCLS when recovering journals
and journal receivers during journaled object recovery.
This additional support is provided when recovering journaled
files or members in user libraries using the Restore Object using
BRM (RSTOBJBRM) command or the Work with Saved
Objects display, or when recovering user libraries containing
journaled files or members using the Restore Library using BRM (RSTLIBBRM)
command or the Work with Media Information display.
Note:
In order for BRMS to store information about saved journals
and journal receivers, you must specify *MBR for Retain
object detail on the BRMS save command or backup control group
attributes.
The extent to which BRMS performs this
additional recovery when restoring a journaled object is dependent
on the current attributes of the Recovery Policy or Restore Command
Defaults. The default is for BRMS to take no action. You must explicitly
indicate through the attributes of the Recovery Policy or Restore
Command Defaults what additional recovery actions you want BRMS to
take (see the Apply journaled changes prompt
in section Recovery Policy).
The following outlines some restrictions on the BRMS capabilities
regarding this additional recovery:
BRMS will only apply/remove journaled changes to physical files
and file members.
BRMS will only apply/remove journaled changes to the objects saved
and restored on the local system (no FROMSYS support).
BRMS cannot apply/remove journal changes
for objects restored to a different library than the saved library
or to different object names.
BRMS cannot apply/remove journal changes
if journaling has not been started for the object.
BRMS cannot restore journals and/or
journal receivers, and apply/remove journal changes if the necessary
object detail is not available. Saved journals and journal receivers
must remain on the system until the backup job completes. In addition,
if saved journals or journal receivers are removed from the system
during the backup job, BRMS will not be able to retrieve information
about these saved objects required to assist with applying/removing
journal changes.
