Dropping a Tablespace with BR*Tools


You can use BR*Tools  for Oracle to drop a tablespace.

This section describes how you drop a tablespace with BR*Tools.

For more information on the approach to dropping a tablespace, see Managing Tablespaces.



       1.      Start the procedure using BRGUI or BRTOOLS, or from the command line:

Ў        BRGUI or BRTOOLS:

                                                  i.       Choose Space Management ® Drop tablespace

BRGUI or BRTOOLS displays the menu BRSPACE options for drop tablespace, where you specify the options with which you call BRSPACE.

                                                ii.       Set the required options:

Menu Entry

Equivalent BRSPACE

Command Option

BRSPACE profile (profile)


Database user/password (user)


Tablespace name (tablespace)

-f tsdrop -t|-tablespace

Confirmation mode (confirm)


Scrolling line count (scroll)


Message language (language)


BRSPACE command line (command)

This shows you the BRSPACE -f tsdrop command that is to be executed using the current settings.

                                               iii.       Choose Continue.

BRGUI or BRTOOLS prompts you to start BRSPACE.

                                               iv.       Choose Continue to start BRSPACE.

Ў        Command line

You need to enter at least the following command:

brspace –f tsdrop

You can enter more parameters, including the tablespace name, if required. For more information, see BRSPACE -f tsdrop.

Whichever way you start the procedure – with BRGUI or BRTOOLS, or from the command line – you can take advantage of quick mode if you know the object name, in this case the tablespace name. For more information, see How to Use BR*Tools.

BRSPACE starts and you see a message that includes Start of BRSPACE processing. From now on, BRSPACE writes a detail log.

       2.      If you have already entered the tablespace name, continue with step 5 (quick mode).

BRSPACE displays the Tablespace drop main menu.

       3.      Choose Drop tablespace.

BRSPACE displays the list of tablespaces.

List Entry

       4.      Select a tablespace.

BRSPACE displays the menu Options for dropping of tablespace.

       5.      Set the required options:

Menu Entry

If the table is not empty, you have to use the option force to immediately delete the tablespace.


Check the results in the BRSPACE logs.

·        The summary log space<DBSID>.logdisplays the return code.

·        The detail log s<encoded timestamp>.tsd displays the details.

·        The structure change log struc<DBSID>.log logs all structure changes.
