You can use BR*Tools  for Oracle to rebuild indexes.

You can use the following types of rebuild:

·        Suspend rebuild (command-line mode only)

·        Resume rebuild (command-line mode only)

For more information, see -f idrebuild.

Procedure

...

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

¡        BRGUI or BRTOOLS:

                                                  i.       Choose Segment Management Rebuild indexes.

BRGUI or BRTOOLS displays the menu BRSPACE options for rebuild of indexes, where you specify the options with which you call BRSPACE.

                                                ii.       Set the required options:

Menu Entry

Equivalent BRSPACE

Command Option

BRSPACE profile (profile)

-p|-profile

-u|-user

Rebuild action (action)

-f idrebuild -a|-action

Tablespace names (tablespace)

-f idrebuild -s|-tablespace

Index owner (owner)

-f idrebuild -o|-owner

Table names (table)

-f idrebuild -t|-table

-f idrebuild -i|-index

Confirmation mode (confirm)

BRSPACE command line (command)

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

Note

If required, you can enter the names of multiple objects in Index names or Table names. You can also use wildcards. For more information, see “Selecting Objects“ in Segment Management with BR*Tools. However, you can only finally select indexes by entering a wildcard with “*” or “<prefix>*” in the Index name. If you enter “*” or “<prefix>*” in Table name, it is treated as a preselection, not a final selection.

You can also specify a list of indexes to be processed with rebuild_index in the initialization profile init<DBSID>.sap.

In Tablespace names and Index owner, you can specify multiple objects but you cannot  use wildcards.

BRSPACE processes all the indexes in the specified tablespace name(s), or all indexes belonging to the specified index owner(s) or tables. But these entries and rebuild action entry are optional.

                                               iii.       Choose Continue.

BRGUI or BRTOOLS prompts you to start BRSPACE.

                                               iv.       Choose Continue to start BRSPACE.

¡        Command line:

...

Enter at least the following command:

brspace –f idrebuild

You can enter more parameters, including the indexes names, if required. For more information, see BRSPACE -f idrebuild.

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 final 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.

       2.      If you have already entered the index names, continue with step 5 (quick mode).

Note

If you have entered multiple indexes, BRSPACE displays as confirmation a List of indexes for rebuild. If you have not already made a final selection, you can make a selection from this list.

Continue with step 5 (quick mode).

BRSPACE displays the Rebuild indexes main menu.
