RE: Changing the SID of a database

Take a backup of the controlfile statement by doing a

 alter system backup controlfile to trace;

Then use this script to create a new controlfile with the new SID after u have transferred all the datafiles, redolog files and archive log files. The first line of the create controlfile script may look aomething like :

 CREATE CONTROLFILE REUSE SET DATABASE "<NAME OF NEW DB>" RESETLOGS ARCHIVELOG Change the path of the log files and other datafiles in the script if they happen to
be different than the old database. Remember to run the create controlfile script in
nomount mode.

Remember to change the db_name parameter in ur parameter file for the new database.

After creating the controlfile, startup the database using the resetlogs option :

 alter database open resetlogs;

Hope this helps,

Samir

I'm going to take the datafiles from a cold backup and use them for a new database. However, to do this, I need to change the SID of the new db. I've read
that it's possible, but not how to do it. Is this an easy thing to do, or would
it be better to extract the tables and create the new db that way?

Thanks for any help.
Rick
