You can use BR*Tools for Oracle to alter indexes as follows:
Coalesce index
Set degree of parallelism
Shrink indexes (Oracle 10g or higher)
Note
This section describes how you alter indexes with BR*Tools.
For more information on the approach to altering indexes, see Segment Management.
Start the procedure using BRGUI or BRTOOLS, or from the command line:
BRGUI or BRTOOLS:
Choose
.BRGUI or BRTOOLS displays the menu BRSPACE options for alter indexes, 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) |
|
Alter index action (action) |
|
Tablespace names (tablespace) |
|
Index owner (owner) |
|
Table names (table) |
|
Index names (index) |
|
Confirmation mode (confirm) |
|
Extended output |
|
Scrolling line count (scroll) |
|
Message language (language) |
|
BRSPACE command line (command) |
This shows you the BRSPACE -f idalter command that is to be executed using the current settings. |
Note
If required, in Table names and Index names you can enter the names of multiple objects. You can also use wildcards. For more information, see “Selecting Objects” in Segment Management with BR*Tools.
In Tablespace names and Table 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 index owner(s) or table(s). But these entries and alter action entry are optional.
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 idalter
You can enter more parameters, including the index names and action, if required. For more information, see BRSPACE -f idalter.
Note
Whichever way you start the procedure - with BRGUI or BRTOOLS, or from the command line - you can use quick mode if you know the object names, in this case the index names. 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.
BRSPACE displays the Alter indexes main menu.
You can use quick mode as follows:
If you have already entered the action, continue with step 4.
If you have already entered the index names and action, continue with step 6.
Note
If you have entered multiple indexes, BRSPACE displays as confirmation a List of indexes for alter. If you have not already made a final selection, you can make a selection from this list.
Continue with step 6 (quick mode).
Choose or confirm the required action:
Coalesce index
Set parallel degree
Shrink indexes
If you have already entered the index names, continue with step 6 (quick mode).
BRSPACE displays the index list:
List Entry |
Meaning |

List sequence number |
Owner |

These examples only apply to input in character mode.
To select the first three indexes in the list, enter 1-3.
To select the first and third indexes, enter 1,3.
To select the first three indexes and the fifth, enter 1-3,5.
To select all indexes, enter 0.
BRSPACE displays the menu, Options for alter of indexes.
Set the required options:
Menu Entry |
Meaning |
---|---|
Current parallel degree (currdeg) – display only |
