You can use BR*Tools for Oracle to show information about indexes.
Start the procedure using BRGUI or BRTOOLS, or from the command line:
BRGUI or BRTOOLS:
Choose
.BRGUI or BRTOOLS displays the menu BRSPACE main options for showing database information, where you specify the options with which you call BRSPACE.
Set the required options:
Menu Entry |
Equivalent BRSPACE Command Option |
---|---|
BRSPACE profile (profile) |
|
Database user/password (user) |
|
Database tablespace (tablespace) |
|
Database owner (owner) |
|
Database table (table) |
|
Database index (index) |
|
Create log file (log) |
|
Confirmation mode (confirm) |
|
Extended output (output) |
|
Scrolling line count (scroll) |
|
Message language (language) |
|
BRSPACE command line (command) |
This shows you the BRSPACE -f dbshow -c idinfo command that is to be executed using the current settings. |
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.
BRSPACE processes all the indexes in the specified tablespace(s), or all indexes belonging to the specified owner(s) or table(s).
Choose Continue
BRGUI or BRTOOLS prompts you to start BRSPACE.
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
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
.If you have already entered a single index name, continue with step 4.
BRSPACE displays the List of database indexes:

If you specified multiple indexes, choose Continue to scroll through.
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.
