DBID = Database Identifier.
The DBID is a unique identifier. It is found in all datafile headers. The DBID
is used to identifiy the database a file belongs to.
The DBID is also found in the control files. It can therefore be gotten without
access to the datafiles (startup mount, select * from v$database)
The dbid is important when the SPFILE or controlfiles must be recovered.
