Maintaining HPOM
Configuring a Database on Multiple Disks
Configuring a Database on Multiple Disks
Although using the Oracle archive log mode helps to reduce the loss of
data after backing up and restoring a database, Oracle offers additional
ways to avoid data loss in the unlikely event that a disk fails.
If you can access more than one disk, you should review the following
configuration tips. Use the information provided when implementing
similar scenarios in your own HPOM environment.
To Move Oracle Control Files to the Second Disk
To move one or more Oracle control files to the second disk, follow these
steps:
1. Create the directories on the second disk:
mkdir -p /u02/oradata/openview
chown oracle:dba /u02/oradata/openview
2. Shutdown the database
3. Move selected control file(s) to a directory on the other disk, for
example from disk /u01 to disk /u02:
mv /u01/oradata/openview/control03.ctl \
/u02/oradata/openview/control03.ctl
4. Modify the control file names in the following file:
$ORACLE_HOME/dbs/init${ORACLE_SID}.ora
Example of old control file names:
control_files = (/u01/oradata/openview/control01.ctl,
/u01/oradata/openview/control02.ctl,
/u01/oradata/openview/control03.ctl)
Example of new control file names:
control_files = (/u01/oradata/openview/control01.ctl,
/u01/oradata/openview/control02.ctl,
/u02/oradata/openview/control03.ctl)
5. Restart the database.
