Hi,

I want to move a datafile from one Location to another location.

Its in Dataguard setup, with ARCHIVLOG mode. I want to do this in Primay db without shutting down the db. Pls tell me if below steps work

a. ALTER DATABASE DATAFILE (OLD LOCATION) OFFLINE
b. Move file to new location
c. ALTER DATABASE RENAME FILE FROM OLD LOCATION TO NEW LOCATION
d. RECOVER DATAFILE (NEW LOCATION)
c. ALTER DATABASE DATAFILE NEW LOCATION ONLINE

Thanks

Hi

I moved the datafile from one location to another location in Primary db successfully.

But I expected the same change to be happened in Standby automatically. But It didnt happened.

How I can accomplish this.

Thanks
Prashanth

Thanks; Standby automatically take care datafile location because your STANDBY_FILE_MANAGEMENT.

It didnt took automatically moving the files in Standby databse once I moved in Primary.

So Do I want to do these steps again manually in Standby db. If so can I follow the same steps which did for PRIMARY db.

When you rename one or more datafiles in the primary database, the change is not propagated to the standby database. Therefore, if you want to rename the same datafiles on the standby database, you must manually make the equivalent modifications on the standby database because the modifications are not performed automatically, even if the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.

The following steps describe how to rename a datafile in the primary database and manually propagate the changes to the standby database.
