Describes how to back up a 32-bit Oracle home database.

1. Start SQL*Plus:

   C:\> sqlplus /NOLOG
   

2. Connect to the database instance as SYSDBA:

   SQL> CONNECT / AS SYSDBA;
   

3. Create a .trc file to use as a template to re-create the control files on the 64-bit computer:

   SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
   

4. Shut down the database:

   SQL> SHUTDOWN IMMEDIATE;
   

5. Perform a full offline backup of the database.
