are using RMAN and would like some direction on how to change the DBID as well, let me know and I will send you some directions/steps for that as well.

  Before I tell
  you procedure, be aware that when you make a clone of your database DBID   remains the same, which is a problem if you use RMAN for you   backups.
<SPAN

  class=054404410-29112001> 
  Steps
  are:
  0. On your
  database issue:
<FONT

  face="Times New Roman" size=3>     <FONT   face=Arial><SPAN lang=EN-US
  style="FONT-SIZE: 12pt; FONT-FAMILY: 'Times New Roman'; mso-bidi-font-size: 10.0pt; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA">alter   database backup controlfile to trace
  resetlogs;

1. Backup your database.
   <SPAN
   class=054404410-29112001>2. Shutdown database (shutdown immediate)
2. Copy all your datafile, logfiles, controlfiles to the new location
3. Edit your new init.ora file and change DB_NAME, DB_BLOCK_SIZE must be the same,

     
  change path for controlfiles, user_dump_dest, background_dump_dest,   core_dump_dest
  5. Edit 
  your new controlfile (which you get in step 0) and change it   in:
<SPAN

  class=054404410-29112001>        CREATE   CONTROLFILE REUSE SET DATABASE 'NEWSID' RESETLOGS
<SPAN

  class=054404410-29112001>    and change the path of datafiles   and logs
  6. Recreate you
  control file.
  7. Change your
  tnsnames.ora and sqlnet.ora files.
<SPAN

  class=054404410-29112001> 
  This should do.   

  I had no
  problems in doing that
