Sirs,
Good day.
I would like to try to rename a newly created dB.
Referring to the topic posted on your website(http://www.orafaq.com/wiki/Oracle_database_FAQ),
I had some clarification before executing the dbrename.sql
mentioned there:
After modifying the the init.ora and tnsnames.ora,
do I have to rename all OLD, existing directory path (for controlfiles, datafiles, etc.) with the new-- meaning I don't have to create another directory for it's 'NEW' name?
Thank you.

Thanks for this.
I successfully used the DBNEWID utility and changed the DBID and the DBNAME. As of now, do I need to rename the old directory (for datafiles, controlfiles, etc.) to the new name because I saw it's still the same. After restarting using the open resetlogs, I had this message:

btw, the old db name was ELAMS, and the new one is LAEISS.

No sure what you did exactly in your end.
It always works for me with something like this. (Warning.Not real code)
export ORACLE_SID=oldSid
nid target= / dbname=newSid
export ORACLE_SID=newSid
sqlplus -s / as sysdba <<EOF
startup force mount pfile='../../newSid.ora';
exit;
EOF
sql> then open database with options.
You need to fix your newSid.ora or spfile.ora what ever you are using. Check for DB_NAME.

I just forgot to modified what's needed, before I restarted.
But now, I edited the oratab and add a new line (for laeiss), I renamed the initelams.ora to initlaeiss.ora and changed the needed parameters, I also made a backup of tnsnames.ora and updated it with the new db name. I noticed that the old (elams) instance is still up...
$ echo $ORACLE_SID
elams
$
$ export ORACLE_SID=laeiss
ORACLE_SID=laeiss: is not an identifier
$ set ORACLE_SID=laeiss
$ . oraenv
ORACLE_SID = [elams] ? laeiss
$ sqlplus / as sysdba
sqlplus: not found
$
but when I'am at the old instance (elams):
$ . oraenv
ORACLE_SID = [laeiss] ? elams
$ sqlplus / as sysdba

Mahesh, Blackswan
The renamed db (LAEISS) is now up and running. I recreated the control files (using the dbrename.sql script that mentioned in the 'How does one rename a database?' topic, re: http://wwww.orafaq.com/wiki/Oracle_database_FAQ) and copy the existing ELAMS (old_name) files to the LAEISS directory I've created.
Thank you very much for your help, sirs!
Regards.
