Showing Segment Extents with BR*Tools 

Use

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

Procedure

...

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

¡        BRGUI or BRTOOLS:

                                                  i.       Choose Segment management → Additional segment functions  → Show segment extents.

BRGUI or BRTOOLS displays the menu BRSPACE main options for showing database information, 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
Database user/password (user)	-u|-user
Database tablespace (tablespace)	-f dbshow -s|-tablespace
Database file (file)	-f dbshow -f|-file
Database owner (owner)	-f dbshow -o|-owner
Database table (table)	-f dbshow -t|-table
Database index (index)	-f dbshow -i|-index

If required, in Database table or Database Index 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, Database file, and Database owner, you can specify multiple objects but you cannot use wildcards.

BRSPACE processes all segment extents for the specified objects.

                                               iii.       Choose Continue.

BRGUI or BRTOOLS displays a further menu, Additional BRSPACE options for showing database information, where you specify the additional options with which you call BRSPACE.

Menu Entry	Equivalent BRSPACE Command Option
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 seinfo command that is to be executed using the current settings.

                                               iv.       Choose Continue

BRGUI or BRTOOLS prompts you to start BRSPACE.

                                                 v.       Choose Continue to start BRSPACE.

¡        Command line:

...

Enter at least the following command:

brspace –f dbshow –c seinfo

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).

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 Show database segment information → Show segment extents.

BRSPACE displays the List of segment extents:

List Entry	Meaning
Pos.	List sequence number
Owner	Segment owner
Type	Segment type: table, index, tabpart, indpart, lobseg, lobind, cluster, rollback, temp, cache
Segment	Segment name
Partition	Partition name if applicable
Tablespace	Tablespace name
Extent Id	Extent ID
File Id	File ID
Block Id	Block ID
Size[KB]	Extent size

       2.      To see more information, select one or more segment extents.

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.

BRSPACE displays Information about extent of segment:

List Entry	Meaning
Segment type (type)	Segment type: table, index, tabpart, indpart, lobseg, lobind, cluster, rollback, temp, cache
Tablespace name (tablespace)	Tablespace name
Data file (file)	Data file name
Extent Id. (extent_id)	Extent ID
File Id. (file_id)	File ID
Relative file number (file_no)	Relative file number
Block Id. (block_id)	Block ID
Extent size in KB (size)	Extent size

       3.      If you specified multiple segment extents, choose Continue to scroll through.

Results

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

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