I have RAC DB running with DG and I need to resize my redo logs files, below are the steps I am thinking:
1. switch the log file couple times and be sure the log group I want to drop is INACTIVE.
2. Drop the INACTIVE log group.
3. create new log group with bigger size.
4. Repeat step 1-3 for the rest log group.
Does it sound right? Also, I have Dataguard and I am on 10G, I wonder what I need to do for the DG DB? Anything I have to watch out?
