Backing up Data on the Management Server
Disadvantages of Automatic Backups
Automatic backups have the following disadvantages:
❏
❏
Archive Log Mode
Oracle archive log mode must be enabled:
• Reduces overall performance
• Requires more disk space
Binaries
No binaries are backed up
Excluding Temporary Files from Automatic Backups
Temporary files (for example, queue files) are excluded from automatic
backups. When a backup starts, the HPOM GUI pops up a notification
window and some OVW maps remain blocked for the duration of the
backup. If a task cannot be completed before the backup starts, the task
remains idle until the backup is finished. After the backup is finished,
the task resumes and completes.
Excluding Oracle Files from Automatic Backups
Automatic backups do not include the Oracle online, redo, and log files,
which cannot be backed up while the database is running. However,
Oracle does allow you to mirror these files on different disks so that they
can be recreated in the event of problems. For details, see the Oracle
documentation.
About the Archive Log Mode in Oracle
The scripts provided by HPOM for automated backups use the online
backup method from Oracle, which requires the database run in archive
log mode. The Oracle archive log mode is not the default setting for the
Oracle database. You have to configure archive log mode manually.
In archive log mode, Oracle stores any changes to data files between full
backups in numbered redo log files. The redo log files are used in the
event of a shut down to restore a configuration from the most recent, full
backup. For details, see Oracle’s product documentation.
