Alter database into Archivelog mode.

Question

HI Team,
I am using ORACLE 9i.
I want to convert database into archivelog mode from noarchivelog mode.
Using the following SQL Commands I can able to convert my database into the Archivelog.
SQL> connect sys as sysdba
Enter password: *****************
Connected.
SQL> alter database archivelog;
alter database archivelog
ERROR at line 1:
ORA-01126: database must be mounted EXCLUSIVE and not open for this operation
SQL> startup mount;
ORA-01081: cannot start already-running ORACLE - shut it down first
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.

Database mounted.
SQL> alter database archivelog;
Database altered.
My problem is that I had to shutdown the database before converting it in to the archivelog mode...
Is there any way that without shuting down the database i can switch to archivelog mode.
Please comments...

Answer 1

if we shutdown immediate one's database..do
it's listener terminated too???The database registration with the listener yes, the listener itself no. That is, if you execute a command like "lsnrctl stat" you won't see the database anymore, but the listener is still active. Example :
[ora102 ~ db102]$ lsnrctl stat
