db name

[mary]

Is there a global variable/parameter I can look at to find the name of the database.

[khussain]

In UNIX type: env
In NT type: set

Variable is ORACLE_SID

[marist89]

select global_name from global_name;

[ora_inf]

I have renamed my database name and when I ran following query
it is giving me old database_name.world

select global_name from global_name;

What needs to be change?

Thanks.

What's the ORACLE_SID???? Your ORACLE_SID should be the new ORACLE_SID before you see the new database name from that query.

[marist89]

This value typically changes when you change your db_name parameter in init.ora. If you don't have that parameter, use:
alter database rename old_db_name to new_db_name.domain

[ora_inf]

When I did
echo $ORACLE_SID
=> changed database name.
ps -ef | grep -i ora
=>changed database name.
lsnrctl status
=>changed database name.

I don't have any ref. old database name then why am I getting the ref.
to old database name.

Thanks.

jeff:

I getting following error

SQL> alter database rename old_db_name to new_db_name.world;
alter database rename old_db_name to new_db_name.world
*
ERROR at line 1:
ORA-02231: missing or invalid option to ALTER DATABASE

Also,
When I renamed the database why do I need to do resetlog?


Thanks.

Actually, to answer Mary's question, your parameter would be: db_name
ie: show parameter db_name

You can also look it up with:

select * from v$instance;
select * from v$database;
