Showing Index Partitions with BR*ToolsLocate this document in the navigation structure

Context

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

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 index partitions 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

        Database index (index)

        -f dbshow -i|-index

        Index partitions (indpart)

        -f dbshow -ip|-indpart

        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 ipinfo command that is to be executed using the current settings.
        Note

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

        In Database tablespace, you can specify multiple objects but you cannot use wildcards.

        BRSPACE processes all the index partitions in the specified tablespace(s), or the index partitions belonging to the specified owner(s), table(s), or index(es).

      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 ipinfo

      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

    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 index partitions End of the navigation path.

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

    BRSPACE displays the List of index partitions:
