The NID utility greatly simplifies this. You can change either the database
name, the database id, or both. It works the same on both UNIX or Windows.
Check Metalink Note #224226.1. I've had to use this several times to finish
off RMAN duplicates on UNIX and once on Windows when I had to change a
database name as part of an application upgrade. It's pretty slick.
From the doc:
Change Only the DBNAME
======================
1. Backup the database
2. SHUTDOWN IMMEDIATE of the database
3. STARTUP MOUNT
4. Open one session and run NID with sysdba privileges
% nid TARGET=SYS/password@test_db DBNAME=test_db2 SETNAME=Y
- the value of DBNAME is the new dbname of the database
- SETNAME must be set to Y. The default is N and causes the
DBID to be changed also.
5. shutdown IMMEDIATE of the database
6. Set the DB_NAME initialization parameter in the initialization parameter
file to the new database name
7. Create a new password file
8. Startup of the database(without resetlogs)
