Optimal / Max redo log size for extremely active Oracle database ( B2B / EDI ) db repository.

 Problem Description:I have a  Db instance with the following Redo usage statistics:

Heavy Day:      68 log switches ( 8gb )  --  544gb redo/day
Avg Day:         44 log switches ( 8gb )  --  352gb redo/day
Minimum Day:  20 log switches ( 8gb )  --  160gb redo/day

Instance Info:  RDBMS 11.2.0.2
Application:  IBM Serling Integrator ( B2B - EDI ) 

I expect processing to increase 20% within 60 days so I am attempting to right size the redo logs for that load target.  The instance has a single Active Data Guard physical standby database.

What is the maximum redo log size reccomended for linux x86-64 ( RHEL 5.6 ) ?

Following the rule of 1-2 redo logs per hour,  I come up with some large numbers suggesting that i need to increase the redo to approximately 18-24gb ???  Any help is appreciated.

Howdy, Stranger!
