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
