Multiplex Oracle managed control file

edited Oct 9, 2013 4:32AM in Database Administration (MOSC) 12 commentsAnswered
Hi,
I just started using OMF. After creation of the database the online redo logs and control files are multiplexed in the two available ASM diskgroups (+DATA, +FRA).

control_files= +DATA/gedspia/controlfile/current.256.827774157
+FRA/gedspia/controlfile/current.256.827774157

db_create_online_log_dest_1 = + DATA
db_create_online_log_dest_2 = + FRA

Up until now I used to have 4 control file copies. control01, control02 in +DATA, control03, control04 in +FRA.

My question is, is this useful anyway, since two copies reside in the same diskgroup?
If it is useful how can I get the same with OMF?

Will setting db_create_online_log_dest_3=+DATA and db_create_online_log_dest_4= +FRA do the trick?

Howdy, Stranger!
