4.2. Backing up the Database
Red Hat recommends performing nightly backups of the Embedded Database and moving the
resulting directory to another system via NFS, SCP, FTP, etc. Preferably, this backup system
resides off-site. To conduct a backup, shut down the database and related services first by
issuing the following command as root:
service rhn-satellite stop
Then switch to the oracle user and issue this command to initiate the backup:
db-control backup DIRNAME
Backup files are stored in the directory specified. Note that this is a cold backup; the database
must be stopped before running this command. This process takes several minutes. The first
backup is a good indicator of how long subsequent backups will take.
Once the backup is complete, return to root user mode and restart the database and related
services with the following command:
service rhn-satellite start
