Showing Instance Status with BR*Tools


You can use BR*Tools   for Oracle to show information about the database instance status.


Some steps in this procedure only apply if your database is an Oracle Real Application Cluster (RAC). These are marked “RAC only.”



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

Ў        BRGUI or BRTOOLS:

                                                  i.       Choose Instance Management ® Show instance status

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)


Database user/password (user)


Database instance (instance)

-f dbshow -n|-instance

                                               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)


Scrolling line count (scroll)


Message language (language)


BRSPACE command line (command)

This shows you the BRSPACE -f dbshow -c dbstate 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.

Ў        Command line:


Enter at least the following command:

brspace –f dbshow –c dbstate

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 instance information ® Show instance status.

       2.      RAC only: if you have already entered the name of the database instance, continue with step 4.

RAC only: BRSPACE displays the List of database instances:

List Entry



List sequence number


Instance name

Number / Thread

Instance number and thread


Instance status

Start time

Time the instance was started


Log redo sequence number


Number of SAP connections

       3.      RAC only: to see more information, select one or more database instances.

These examples apply only 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.
