Procedure documentationShowing Indexes with BR*Tools

 

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

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 indexes 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

        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, you can enter the names of multiple objects in Database index or Database table 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.

        End of the note.

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

      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 idinfo

      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 indexes End of the navigation path.

    End of the note.

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

    BRSPACE displays the List of database indexes:

    List Entry

    List sequence number

    Owner

    Table owner

    Table

    Table name

    Index

    Prt.

    Partitioned (yes / no)

    Prts

    Number of partitions for partitioned table

    Mon.

    Index usage monitoring

    Para.

    Degree of parallelism

    Tablespace

    Tablespace name

    Analyzed

    Date last analyzed by update statistics

    Rows

    Number of rows

    Space[KB]

    Total space allocated to the index

    Used[KB:%]

    Used space in index: percentage of total space used

    Data [KB:%]

    Amount of data in index: percentage of total space for data

    To see more information, select one or more indexes.

    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.

    BRSPACE displays Information about index:

Result

If you set the option Create log file (parameter -l|-log), check the results in the BRSPACE logs.

  • The summary log space<DBSID>.log displays the return code.

  • The detail log s<encoded timestamp>.dbw displays the details.
