Multiplexing the Online Redo Log
Oracle recommends that you multiplex the online redo log. Multiplexing provides
better protection for data if an instance or media failure occurs.
To multiplex your online redo log, you must add members to each online redo log
group. It is not required that online redo log groups be symmetrical, but Oracle
recommends that your groups all have the same number of members. A database
must have a minimum of two online redo log groups.
To multiplex the online redo log:
1. In EM Express, from the Storage menu, select Redo Log Groups.
The Redo Log Groups page appears.
2. Select a group and click Add Member.
The Add Member page appears.
