    • Article Type: General
    • Product: Aleph

    Desired Outcome Goal:
    Data file has a different name and / or is in a different location (e.g. partition or directory)

    Procedure:
    (1)
    Shut down the Ex Libris application.


    (2)
    Log on to the server where the Oracle database of the Ex Libris application is running as the UNIX user that owns the Oracle software (e.g. UNIX user oracle).


    (3)
    Shut down the Oracle database by entering the following commands as UNIX user oracle:

    $ echo $ORACLE_SID
    (make sure that the value of this variable specifies the correct Oracle database)


    $ sqlplus / as sysdba
    SQL> shutdown immediate
    SQL> exit


    (3)
    Copy the data file to the new name / location at the operating system level (as UNIX user oracle).


    (4)
    Start the database and bring it into status MOUNTED by entering the following commands as UNIX user oracle:

    $ sqlplus / as sysdba
    SQL> startup mount


    (5)
    Rename the data file within the Oracle database by entering the following SQL statement:

    SQL> > ALTER DATABASE RENAME FILE
    '/<full_path_of_old_location>/<old_datafile_name.dbf>'
    TO
    '/<full_path_of_new_location>/<new_datafile_name.dbf>';



    (6)
    Bring the database into status OPEN by entering the following SQL statement:

    SQL> ALTER DATABASE OPEN;


    (7)
    Verify that the data file is at the correct location and has the correct name by entering the following SQL statement:

    SQL> SELECT * FROM V$DBFILE;


    (8)
    Start the Ex Libris application.


    (9)
    Remove the data file from the old location at the operating system level.
