Procedure documentationShowing Tables with BR*Tools

 

You can use BR*Tools for Oracle to show information about tables.

Procedure

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

    • BRGUI or BRTOOLS:

      1. Choose Start of the navigation path Segment management Next navigation step Additional segment functions Next navigation step Show tables End of the navigation path.

        BRGUI or BRTOOLS displays the menu BRSPACE main options for showing database information, where you specify the options with which you call BRSPACE.

      2. Set the required options:

        Menu Entry

        Equivalent BRSPACE Command Option

        BRSPACE profile (profile)

        -p|-profile

        Database user/password (user)

        -u|-user

        Database tablespace (tablespace)

        -f dbshow -s|-tablespace

        Database owner (owner)

        -f dbshow -o|-owner

        Database table (table)

        -f dbshow -t|-table

        Create log file (log)

        -f dbshow -l|-log

        Confirmation mode (confirm)

        -c|-confirm

        Extended output (output)

        -o|-output

        Scrolling line count (scroll)

        -s|-scroll

        Message language (language)

        -l|-language

        BRSPACE command line (command)

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

        Note Note

        If required, in Database table you can enter the names of multiple tables by using wildcards. For more information, see Selecting Objects in Segment Management with BR*Tools.

        In Database tablespace and Database owner, you can specify multiple objects but you cannot use wildcards. BRSPACE processes all the tables in the specified tablespace(s) or all tables belonging to the specified owner(s).

        End of the note.

      3. Choose Continue

        BRGUI or BRTOOLS prompts you to start BRSPACE.

      4. Choose Continue to start BRSPACE.

    • Command line:

      Enter at least the following command:

      brspace -f dbshow -c tbinfo

      You can enter more parameters if required. For more information, see BRSPACE -f dbshow.

    BRSPACE starts and you see a message that includes Start of BRSPACE processing. From now on, BRSPACE writes a detail log if you set the option Create log file (parameter -l|-log).

    Note Note

    If you started BRSPACE from the command line without the information class name (-c|-class) – that is, with brspace -f dbshow – BRSPACE displays the Show database information main menu.Choose Start of the navigation path Show database segment information Next navigation step Show tables End of the navigation path.

    End of the note.

  2. If you have already entered a single table name, continue with step 4.

    BRSPACE displays the List of database tables:

    Used[KB:%]

    Used space in table: percentage of total space used

    Data [KB:%]

    Amount of data in the table: percentage of total space for data

  3. To see more information, select one or more tables.

    Example Example

    These examples only apply to input in character mode.

    To select the first three entries in the list, enter 1-3.

    To select the first and third entries, enter 1,3.

    To select the first three entries and the fifth, enter 1-3,5.

    To select all entries, enter 0.

    End of the example.
