/opt/oracle/data/DEV3/system01.dbf

/opt/oracle/data/DEV3/sysaux01.dbf

/opt/oracle/data/TEST01.dbf

Here my TEST tablespace datafile is not in DEV3 location, so I wanted to move into /DEV location.

Here I’m testing in my DEV database but make sure no one using this tablespace if this is doing in prod database J

1)      Make the corresponding Tablespace OFFLINE

        SQL> ALTER tablespace TEST offline;

                  Tablespace altered.

2)      Update the data dictionary pointing to new location using below command:

         SQL> ALTER DATABASE RENAME FILE  '/opt/oracle/data/TEST01.dbf'  to    '/opt/oracle/data/DEV3/TEST01.dbf';

                 Database altered.

3)      Now, recover the datafile from new location:

         SQL> RECOVER DATAFILE '/opt/oracle/data/DEV3/TEST01.dbf';

                   Media recovery complete.

4)      Bring back the TEST tablespace ONLINE

         SQL>  ALTER tablespace TEST online;

                   Tablespace altered.

SQL> select name from v$datafile;

NAME

--------------------------------------------------------------------------------

/opt/oracle/data/DEV3/system01.dbf

/opt/oracle/data/DEV3/sysaux01.dbf

/opt/oracle/data/DEV3/TEST01.dbf

Now my TEST datafile moved to the new location.
