How do I find out the “redo log file max size” in Oracle 11R2

set linesize 300 column

REDOLOG_FILE_NAME format a50

SELECT a.GROUP#, a.THREAD#, a.SEQUENCE#, a.ARCHIVED, a.STATUS, b.MEMBER AS REDOLOG_FILE_NAME, (a.BYTES/1024/1024) AS SIZE_MB FROM v$log a JOIN v$logfile b ON a.Group#=b.Group# ORDER BY a.GROUP# ASC;



Output : 


GROUP #THREAD# SEQUENCE# ARC STATUS REDOLOG_FILE_NAME SIZE_MB ---------- ---------- ---------- --- ---------------- --------------------- 1 1 4 YES INACTIVE /ORACLE/oradata/orcl1/redo01.log 50 2 1 5 YES INACTIVE /ORACLE/oradata/orcl1/redo02.log 50 3 1 6 NO CURRENT /ORACLE/oradata/orcl1/redo03.log 50
