Maintaining OVO
Configuring a Database on Multiple Disks
To Create Another Set of Mirrored Online Redo Logs
You can create a second (or even third) set of mirrored, online redo logs
on the second (or third) disk. OVO installs Oracle in such a way that, by
default, it has three redo log groups, each containing one member.
The following procedure creates a second set of redo log files in the
directory. /u02/oradata/openview. Modify the directory names (and
repeat the steps) as required.
To create a second set of redo logfiles, follow these steps:
1. Create the directories on the second disk.
Example:
mkdir -p /u02/oradata/openview
chown oracle:dba /u02/oradata/openview
2. As user oracle, enter the following:
sqlplus /nolog
SQL>connect / as sysdba
alter database add logfile member
‘/u02/oradata/openview/redo01.log’ to group 1;
alter database add logfile member
‘/u02/oradata/openview/redo02.log’ to group 2;
alter database add logfile member
‘/u02/oradata/openview/redo03.log’ to group 3;
exit
