Hi Gurus,

Can someone share your comments and inputs in regard to the multiplexing of the online redo log files and control files in an ASM environment?

Scenario:

A. 2 diskgroups: DATA_DG and FRA (Flash Recovery Area)
B. Each of the 2 disk groups will have 3 raw devices, like this
DATA_DG: /dev/raw/raw1, /dev/raw/raw2, and /dev/raw/raw3
FRA: /dev/raw/raw4, /dev/raw/raw5, and /dev/raw/raw6
C. Each of the raw devices will be 100 GB /per device.
D. We will have 3 copies of control files and 3 groups of online redo log files; each the 3 online redo group will have 2 members.

With this scenario, FRA will be the destination for the archive log files. Do you think FRA will be a good locations for multiplexing the redo log files?

Or could someone share your own practice and experience on this topic?

Thanks in advance for your help!
