Hi,
in 10g R2 on Win 2003, I have created new log groups and want to DROP the ancient , then I wait that it beocmes INACTIVE.


According to documentation :

•You can drop a redo log group only if it is inactive. If you need to drop the current group, first force a log switch to occur.

SELECT GROUP#, ARCHIVED, STATUS FROM V$LOG;

   GROUP# ARC STATUS
--------- --- ----------------
        1 YES ACTIVE
        2 NO  CURRENT
        3 YES INACTIVE
        4 YES INACTIVE

I try ALTER SYSTEM SWITCH LOGFILE; every now and then , but it is always INACTIVE.

Thank you.
