Post activity for drop & recreating log group

Question

Hi,
We need to drop redolog group from old file system & going to recreate in different file system.
ex,
when group 3 is in "INACTIVE"
alter database drop logfile group 3;
alter database add logfile group 3 ('/u01/oracle/ica01/log3.ora,'/u01/oracle/ica02/log3.ora’ ) size 2G;
Is there any post activity to update in control files or any other things ?
Thx,
Gowin.

That's if you are moving an existing file. The OP was asking about dropping an existing file and creating a new one. While the purpose may be the same (to relocate a file), the technique is vastly different and so the answer to his question is vastly different.
To the OP: as you described your actions of dropping a redo log group and "recreating" it, the answer is no, there is no follow up work to be done. You did two logically un-connected actions:
First, you dropped a redo log group. Fine. That is easily done online with no impact to the users and requires no follow-up actions.
Second, you created a redo log group. Fine. That is easily done online with no impact to the users and requires no follow-up actions.
The fact that the new redo log group has the same group name as the former - now non-existent - group is merely coincidental.
