archived. For more information, see the appropriate Oracle
documentation. For information on how to set up Archive-log mode in
ITO, see “Maintaining the Database” on page 468 and the section on
database tasks in the HP ITO Administrator’s Guide to Online
Information.
Off-line Backup
The
opc_backup
tool offers two backup possibilities, which allow you to
backup ITO configuration data only, include the current and history
messages, too, or do a full backup that includes the ITO binaries and
installation defaults. However, all ITO GUIs have to be shut down and
all OpenView services stopped, including the ITO server processes. Then,
the Oracle database is shut down, and a complete off-line backup is
performed. If you are considering using this method to backup your data,
the following advantages and disadvantages should be noted:
• archive-log mode is not needed, which means
• better overall performance
• less disk space required
• you can only recover to the state of the most recent full backup
• binaries are backed up, too (if full mode is used)
• all OV services and GUIs have to be stopped
For an overview of the backup functions, see the following man pages:
opc_backup(1M)
and
opc_recover(1M)
.
Automated Backup
ITO integrates its own backup and restore scripts with those provided by
Network Node Manager (NNM),
ovbackup.ovpl
, and
ovrestore.ovpl
in order to carry out a complete automated backup of
the database while the ITO GUI and server processes are running. This
automated backup is designed to be run with a
cron
job or an ITO
scheduled action. For more information on the NNM automated-backup
scripts as well as the automated-backup scripts provided by ITO, see the
sections; “The ovbackup.ovpl Command” and “The ovrestore.ovpl
Command” on page 465.
