System Maintenance
System Maintenance
You perform system maintenance on both the management server and on
managed nodes. Management server maintenance is split into the
following areas:
❏
System backups
❏
Database
❏
HP OpenView platform
❏
ITO directories and files
You can configure scheduled actions to help you with routine
system-maintenance tasks. For more information on how to schedule
actions, see the HP ITO Administrator’s Guide to Online Information.
On The ITO Management Server
ITO provides the following methods for backing up data on the ITO
management server:
•
opc_backup
- off-line backup
•
ovbackup.ovpl
- automated backup
The ITO configuration is not only on the management server but also on
the managed nodes. Consequently, if the restored configuration on the
management server does not match the current configuration on a
managed node, errors relating to missing instruction text or incorrectly
assigned templates may occur. For this reason, it is recommended that
after a backup has been restored, the templates, action, command and
monitor scripts are redistributed to all managed nodes using the
force
update
option.
Data backed-up with one tool must be recovered with the backup tool’s
corresponding restore tool. For example, use
opc_recover
to restore
data backed up with
opc_backup
: similarly,
ovrestore.ovpl
must be
used to recover data saved using
ovbackup.ovpl
.
NOTE
Archive-log mode is a term used in Oracle to denote a state in which
periodic automatic saves of data are performed and any changes to data
files stored in redo log files. These redo log files are subsequently
