Help regarding oracle 9i on linux (urgent...)

Question

Our is IBM machine with oracle 9i and linux.
There are two databases orcl, orcl1
suddenly some problem is coming.
when we run the service from /etc/init.d
ERROR
ora -00327 : log 3 of thread1, physical size 119853 less than 204800
ora-00312: online log3 og thread : /home/oracle/oradata/sa/redo03.log
Database "orcl1" warm started
when we run sqlplus username/password@orcl1
ERROR ora-01033 : Oracle Initialization or shutdown in progress.
when we do sqlplus /nolog
connect / as sysdba;
startup nomount;
alter database mount;
alter database open;
all are successful.
if we check select * from v$logfile, it shows of orcl.
we want of orcl1.
what to do
thanks in advance.

Answer 1

If it's not the active group and there are at least 2 other groups, you can drop the group (and recreate it afterwards).
In MOUNT status connect in sqlplus as sysdba:
alter database drop logfile group 3;
If the logfile is the Current logfile, then do the following (possible loss of data):
recover database until cancel;
Type Cancel when prompted
alter database open resetlogs;
Hopefully you don't see something like:
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error
below
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: xxxxxxxx
In this case , without backups, you have to recreate the database.
