The ovbackup.ovpl Command.
The automated backup command
ovbackup.ovpl
pauses running processes and flushes their data to disk
before backing up the NNM databases and the data of integrated
applications. After the backup has completed, the NNM processes are
resumed. The command accepts the following options:
ovbackup.ovpl [-operational] [-analytical] [-d \
<destination>]
If the
-d
option is not specified, the following default location is used;
/var/opt/OV/tmp/ovbackup
. If the
-d
option is specified, the
following location is used;
<destination>/ovbackup
. The destination
defined with the
-d
option must be a file system (which may be mounted)
and should contain sufficient space to complete the backup.
Approximately 300MB of free disk space is required to backup a fresh
ITO installation: bigger environments wil require more space. The
backup may then be completed by using a command such as
fbackup
to
save the backup to an archive medium such as a tape device. For more
information on the command-line options, see the man page
ovbackup.ovpl(1M)
. Briefly,
ovbackup.ovpl
carries out the following
high-level steps:
• Backup operational data (if the
-operational
option or no option at
all is specified):
1. Run all of the backup scripts found in the directory;
$OV_CONF/ovbackup/pre_pause/
including the ITO script:
ito_oracle.sh
, which performs the on-line backup of the Oracle
database outside the
ovpause
time-frame and moves the (old)
archive log files to the staging area. These archive logs are not
subsequently restored: they are only required if the backup is
corrupt for some reason and an earlier backup has to be used.
2. Call
ovpause
to pause all NNM processes (and block OVW API
calls).
3. Run all the backup scripts found in the directory;
$OV_CONF/ovbackup/checkpoint/operational/
including
the ITO script:
ito_checkpoint.sh
, which reads the current
time stamp of Oracle, copies to the staging area those offline redo
