OPTIMAL_LOGFILE_SIZE

Hi,

on 11.2.0.4 on Unix

I have 10Gb proposed by advisor for log file size :

select optimal_logfile_size from v$instance_recovery

OPTIMAL_LOGFILE_SIZE

---------------------------------------

10215

Is it a reasonable value ?

Am-I wrong somewhere ?

select group#,bytes from v$log;

GROUP#

BYTES

--------------------------------------- ---------------------------------------
