The DBID will come into play if you have to recover a control file from an 
automated rman backup. Go figure, this information isn't readily available 
unless you know where to look. You can find the DBID in the following places:

1.  from the v$database view::

        SQL> select name, dbid from v$database;
        
        NAME            DBID
        --------- ----------
        OCI1      1369681761

2.  From the rman opening screens::

        $ rman target /

        connected to target database: OCI1 (DBID=1369681761)
    
 3. From the alert log: look for a automatic backup.
