How to multiplex redo log files

edited May 18, 2017 5:26AM in Storage Management (ASM ACFS DNFS ODM) (MOSC) 7 commentsAnswered ✓

@SURESH KATTA_OCP@ElonDBA@ you please provide the steps to multiplex a redo log file.

I am trying with the following method.

Shutdown immediate

startup mount

alter database add logfile group 1  C:\ORACLE\ORADATA\SITE1\REDO01.LOG' size 50m;

ERROR at line 1:

ORA-01184: logfile group 1 already exists

same member is available in the group1 already in \Oracle\oradata\site1\redo01.log location.

But in 11g we had same redo member in same group but in different storage location. It was allowed.

Oracle12c it is not allowing.

Can anyone help me to fix this

Regards,

Lakshmi
