Oracle in a Nutshell

Name

DUPLICATE

Synopsis

Oracle9i syntax:

DUPLICATE TARGET DATABASE 
   { TO [']database_name['] 
     [ [dupOptionList] [dupOptionList ...] ]
   | FOR STANDBY [ [dupsbyOptionList] 
       [dupOptionList ...] ]
   };

dupOptionList :=
{ LOGFILE logSpec [, logSpec]... 
| NOFILENAMECHECK 
| SKIP READONLY 
| DEVICE TYPE deviceSpecifier [, deviceSpecifier ...] 
| PFILE [=] [']filename[']
} 

logSpec := 
{ 'filename' [SIZE integer [ K | M ] [REUSE]]
| GROUP integer ('filename' [, 'filename' ...]) 
   [SIZE integer [ K | M ] [REUSE]] }

dupsbyOptionList :=
{ DORECOVER | NOFILENAMECHECK }

Oracle8i syntax:

DUPLICATE TARGET DATABASE TO [']database_name[']
   [ LOGFILE logSpec [, logSpec ...]]
   [ NOFILENAMECHECK ]
   [ SKIP READONLY ];

logSpec := 
   { 'filename' [SIZE integer [ K | M ] [REUSE]]
   | GROUP integer ('filename' [, 'filename' ...]) 
      [SIZE integer [ K | M ] [REUSE]] }

Creates a duplicate database, or a standby database, from the backups of a target database. For Oracle8i, you must execute this command from within the RUN command.

Keywords

NOFILENAMECHECK

Causes RMAN not to check to see if the target database filenames are the same as those in the duplicate database. Use this option only when duplicating a database to a different host, in which case it is acceptable for the directory names and the filenames to be the same.

PFILE

Specifies the location of the parameter file for the duplicated database. RMAN uses the parameter file at this location, which you must have previously created, to start the duplicated database. You must specify ...
