Preparing For Disaster Recovery
7.1 Disaster Recovery for OpenVMS Systems
7.1.3 Backup of ABS$ROOT
Backing up ABS$ROOT with ABS will always find the ABS log files open for write because a
save request always has a catalog file open for write. Not all catalog files might be accessible
through ABS$ROOT. For example if you have created a search list for ABS$CATALOG and
extensions to ABS$CATALOG point to other directories and/or disk devices.
If ABS$ROOT is not located on your system disk or you want a separate save operation, you can
use a separate SAVE object like this:
Example 7–3 Save Object for Disaster Recovery of ABS$ROOT
Save: DISASTER_RECOVERY
Description:
Access Control: BONFYR::ABS (READ, WRITE, EXECUTE, DELETE, SET,
SHOW,
CONTROL)
Owner: BONFYR::ABS
Archive: DISASTER_RECOVERY
Base Date: NONE
Delete Interval: NONE
Environment: DISASTER_RECOVERY_ENV
Epilogue: @ABS$SYSTEM:ABS$DISASTER_RECOVERY EPILOG
Execution Nodes: BONFYR
Explicit Interval:
Frequency: DAILY
Groups:
Incremental: NO
Job Number: 0
Prologue: @ABS$SYSTEM:ABS$DISASTER_RECOVERY PROLOG
Schedule: DISASTER_RECOVERY_SAVE_SCHED
Sequence Option: SEQUENTIAL
Skip Time: NONE
Start Date: NONE
Transaction Status:
Selections: DISASTER_RECOVERY_SAVE_SEL_DEF
Default Selection -
- Data Select Type: VMS_FILES
- Include: ABSS$ROOT:[000000...]*.*;*,
- Exclude: [*...]COORD_CLEANUP.DAT;*,[*...]*.LOG;
- Source Node:
If this object does not exist on your system run the ABS database initialization program:
$ RUN SYS$SYSTEM:ABS$DB_INIT
This program adds all the missing default ABS objects to the MDMS database.
This save request excludes all the files open for write by ABS like the current logfile and the
database file used by the coordinator cleanup process (“ABS$COORD_CLEAN”). There should
not be any error message in the save log file.
You have to make sure that you use the DISASTER_RECOVERY archived with an empty catalog
name defined. The disaster recovery archive is the only archive which allows no catalog
name. Otherwise you get open and verify errors for the catalog being used.
If you have an extended ABS$CATALOG search list, then you have to include the extra entries
in the include specification as well. By default the catalog subdirectory is included under
ABS$ROOT.
If you want, you can combine the save of the MDMS$ROOT and the ABS$ROOT into one save
object.
