Note: This chapter only applies to Discoverer Plus Relational and Discoverer Viewer with relational and OLAP worksheets. For more information about configuring Discoverer Plus OLAP, see Chapter 6, "Configuring the Discoverer Catalog and Discoverer Plus OLAP".
This chapter explains how to manage OracleBI Discoverer preferences, and contains the following topics:
Section 10.4, "How to set default user preferences for all users"
Section 10.5, "How to set individual preferences for specific users"
Section 10.7, "How to convert a Discoverer preferences file to a different platform format"
Discoverer preferences are settings that define the Discoverer environment and control the behavior of Discoverer Plus and Discoverer Viewer.
There are two types of Discoverer preference:
Discoverer system preferences (for more information, see Section 10.2, "About Discoverer system preferences")
Discoverer user preferences (for more information, see Section 10.3, "About Discoverer user preferences")
Discoverer system preferences are created and set during installation. Typically you will never have to modify the Discoverer system preferences. System preferences are stored as follows:
On UNIX systems, the Discoverer system preferences are stored in the opmn.xml file.
On Windows systems, the Discoverer system preferences are stored in the Windows Registry and the opmn.xml file.
Figure 10-1 Discoverer System preferences
During installation, Discoverer uses factory supplied default values (stored in defaults.txt) to create user preferences for all Discoverer users (stored in pref.txt).
When a new user starts an OracleBI Discoverer session for the first time, the settings in the pref.txt file take effect as that user's default settings.
After installation, the user preferences can be changed in a number of ways:
Discoverer end users can change their own user preferences using options within Discoverer Plus or Discoverer Viewer. For example, a Discoverer Viewer end user might click Preferences and change their personal preferences. When an individual user changes a preference, this change is stored in the reg_key.dc file on the Discoverer middle tier (to find out the location of this file, see Section A.1, "List of Discoverer file locations").
Individual preferences are stored for each user as a unique combination of database and userid in the reg_key.dc file, and loaded whenever the user starts a new session. Therefore, users can log on from different client machines and still have their individual settings take effect.
For example, a Discoverer Plus end user might select Tools | Options to display the Options dialog and change the Number of rows per page value to 15. The following entry might be stored in reg_key.dc for that user:
"RowsPerHTML"=D4:4:00,00,00,0F
where '0F' is the hexadecimal value of 15.
Note: Unless a user changes a preference value, the value of that preference is as specified in the pref.txt file.
You can change the default preference values that Discoverer end users are presented with by changing the values in the pref.txt file. For the changes to take effect, you must 'apply' the preferences. For more information about changing default preference values, see Section 10.4, "How to set default user preferences for all users".
You can change an individual user's preferences using the Discoverer preferences command line utility. Changes that you make are stored in the reg_key.dc file (for more information about changing individuals users' preferences, see Section 10.5, "How to set individual preferences for specific users").
Notes
On UNIX implementations, the .reg_key.dc is a hidden UNIX file (i.e. the filename is prefixed with a '.'). Type the command ls -al to list hidden files.
Never edit the reg_key.dc file directly. You must only change values in reg_key.dc using the Discoverer preferences command line utility dis51pr (to find out the location of this file, see Section A.1, "List of Discoverer file locations").
If you delete the reg_key.dc file, you lose preferences set by Discoverer end users or preferences set using the Discoverer preferences command line utility. Default preferences stored in pref.txt are applied.
The factory supplied default values for pref.txt are contained in the defaults.txt file (to find out the location of this file, see Section A.1, "List of Discoverer file locations"). If you make a mistake when editing the pref.txt file (or lose or corrupt the file), refer to defaults.txt to restore the content of pref.txt to the original values.
Maximum values for numeric preferences are documented in the pref.txt file.
You can edit the pref.txt file without shutting down the Preferences component. In other words, users can continue working while you edit the pref.txt file.
If you want to deploy Discoverer on multiple machines, you might want to use a centralized set of Discoverer preferences. You do this by specifying one Discoverer Preferences server machine and turning of the Discoverer Preferences component on the other machines. For more information, see Section 7.6, "About the Discoverer Preferences component in a multiple machine environment".
You set default users preferences for all users when you want to globally configure Discoverer. To set default user preferences for all users you edit the pref.txt file on the Discoverer Preferences server (for more information about the Discoverer Preferences server, Section 7.6, "About the Discoverer Preferences component in a multiple machine environment").
Note: Changes that you make to the default user preferences only apply to new end users, or end users who have not changed their settings. Changes do not affect end users who have already changed their own settings.
To set default user preferences for all users:
On the host machine, open the pref.txt file in a text editor (to find out the location of this file, see Section A.1, "List of Discoverer file locations").
Edit the items in the pref.txt file as required.
Save the pref.txt file.
Stop the OracleBI Discoverer service (for more information, see Section 5.3, "About starting and stopping the Discoverer Service").
Run the applypreferences script to apply the preference changes you have made (for more information about the applypreferences script, see Section A.1, "List of Discoverer file locations").
You must run the applypreferences script from the host machine.
Hint: Check for error messages in the error.txt file in the current directory to verify that the preferences were applied correctly (for more information about the location of configuration files, see Section A.1, "List of Discoverer file locations").
Start the OracleBI Discoverer service (for more information, see Section 5.3, "About starting and stopping the Discoverer Service").
To set individual preferences for specific users:
From the command prompt, navigate to the directory containing the Discoverer preferences command line utility dis51pr (to find out the location of this file, see Section A.1, "List of Discoverer file locations").
Use the Discoverer preferences command line utility to enter a command at the command prompt, using the following syntax:
dis51pr -user <user> -setpref <"preference category"> <"preference name"> <"preference value">
where:
<user> is the name of the user for which you want to set the preference value, followed by the @ symbol, followed by the name of the database (e.g. jchan@salesdb)
<"preference category"> is the category of the preference you want to change (e.g. "Database")
<"preference name"> is the name of the preference you want to change (e.g. "DefaultEUL")
<"preference value"> is the value you want the preference to have
Examples:
if you want to set the default EUL to Sales for the user jchan, type the following at a command prompt:
dis51pr -user jchan@salesdb -setpref "Database" "DefaultEUL" \\"Sales\\"
if you want to set the maximum amount of heap memory allowed for the data cache to 512000 for a user jchan, type the following at a command prompt:
dis51pr -user jchan@salesdb -setpref "Application" "MaxVirtualHeapMem" 512000
Notes
To display online help for the Discoverer preferences command line utility, type the name of the script followed by -help (e.g. dis51pr -help).
Preference names and values are case-sensitive.
When specifying a string as a preference value, prefix the string with \\" and end the string with \\". For example, if the preference value is Sales, enter \\"Sales\\".
For a list of Discoverer preferences that you can set using the Discoverer preferences command line utility, see Section 10.6, "List of Discoverer user preferences".
This table shows the category, description, default value, and valid values of Discoverer user preferences.

The EnhancedAggregationStrategy user preference controls how Discoverer Plus and Discoverer Viewer make use of the Oracle9i (and later) database's enhanced aggregation functionality.
The settings control the SQL that is generated for the query, and specify whether there should be an exact match between client request and the aggregation levels retrieved from the database, or whether more aggregation levels are retrieved from the database than are requested by the client.
The table below explains the EnhancedAggregationStrategy user preference settings in more detail:
| Value | Description |
|---|---|
| 0 | Off
The generated SQL contains an ordinary GROUP BY clause. |
| 1 | Strict Grouping Sets
The generated SQL contains GROUPING SET requests that exactly match the GROUPING SET requests made by Discoverer. The requests that Discoverer makes are determined by how the end user created the worksheet. For example, the generated GROUP BY clause might be similar to the following: GROUP BY GROUPING SETS((Department, Region, Year),(Department),()) Note: This value (the default) might be used if you want to maximize performance. |
| 2 | Optimized
The generated SQL contains GROUPING SET requests with additional ROLLUP functions. The use of ROLLUP functions enables the SQL to fetch more aggregation levels than requested by Discoverer. This typically enables the end user to add totals or pivot without needing to re-query the database. For example, the generated GROUP BY clause might be similar to the following: GROUP BY GROUPING SETS(ROLLUP(Department, Region, Year), ROLLUP(Region, Year)) Note: This value might be used if worksheet users do a lot of drilling or pivoting when using worksheets. |
| 3 | Cube
The generated SQL contains a Grouping Set request for a CUBE of the items requested. This is the highest pre-fetch strategy for aggregation levels from the database and should be used with caution as there might be a severe performance overhead in increased query time and resource usage. For example, the generated GROUP BY clause might be similar to the following: GROUP BY GROUPING SETS(CUBE(Department, Region, Year)) |
| 4 | Auto Determine
Discoverer automatically determines which of the above strategies to use (i.e. 1, 2, or 3 above). |
You specify a Discoverer timeout if you want Discoverer sessions to shut down automatically after a specified time period if no user interaction has occurred during that time. Before Discoverer shuts down, a warning message is displayed. For example, if a Discoverer session is not used for ten minutes, the Discoverer session will shut down. The Discoverer end user will have to reconnect to use Discoverer again.
Discoverer timeout values are specified as follows:
In Discoverer Plus, the Timeout value in the pref.txt file specifies the timeout value (for more information, see the Timeout preference in Section 10.6, "List of Discoverer user preferences").
In Discoverer Viewer, the session-timeout value in the web.xml files specifies the timeout value (for more information, see Section 10.6.3, "How to set the timeout value for Discoverer Viewer").
To set the timeout value for Discoverer Viewer:
Open the web.xml file in a text editor or XML editor (for more information about the location of configuration files, see Section A.1, "List of Discoverer file locations").
Look for a session-timeout tag, e.g.
<session-timeout>10</session-timeout>
If the web.xml file contains a session-config tag, update the session-timeout value as required (in minutes).
If the web.xml file does not contain a session-config tab, add the following text to the end of the file, immediately before the closing </web/app>:
<session-config>
<session-timeout>10</session-timeout>
</session-config>
Note: Change the value '10' (i.e. ten minutes) as required.
Save the web.xml file.
Restart the Discoverer components (for more information, see Section 5.5, "How to start and stop the Discoverer servlets").
When users next start Discoverer Viewer, Discoverer will impose the specified timeout value.
Oracle Business Intelligence Discoverer stores registry settings in the reg_key.dc file. If you want to move a Discoverer installation from one platform to another platform (e.g from Windows to Solaris), you must convert the reg_key.dc file to change the format of integer values (e.g. from BigEndian format to LittleEndian format). You change the format of integer values using the convertreg.pl script that is installed with Oracle Business Intelligence. For more information about the location of configuration files, see Section A.1, "List of Discoverer file locations".
You must convert the reg_key.dc file when you move between the following platforms:
Windows/Linux to Solaris/HPUX/AIX
Solaris/HPUX/AIX to Windows/Linux
Note: Do not use the convertreg.pl script to convert the reg_key.dc file between Windows to Linux.
To convert a Discoverer preferences file to a different platform format:
Copy the reg_key.dc file from the source machine to the target machine (e.g. from the Windows machine to a Solaris machine).
On the target Oracle Business Intelligence installation, run the convertreg.pl script at the command prompt:
perl convertreg.pl <old file name> <new file name>
Where:
<old file name> is the name of the original reg_key.dc file
<new file name> is the name that you want to give the file produced by the convertreg.pl script
Note: For more information about the location of configuration files, see Section A.1, "List of Discoverer file locations".
For example, if the source file is called windows_reg_key.dc, you might type:
pl convertreg.pl windows_reg_key.dc solaris_reg_key.dc
If required, rename the target file.
If you named the target file solaris_reg_key.dc, rename this file as reg_key.dc.
You have now converted the reg_key.dc to the correct format for the target platform.
You migrate OracleBI Discoverer preferences when you want to upgrade to a new version of Discoverer. For example, you might want to upgrade from OracleBI Discoverer Version 9.0.4 to OracleBI Discoverer Version 10.1.2.
How you migrate Discoverer preferences depends on which version of Discoverer you are using, as follows:
if you are upgrading from OracleBI Discoverer Version 9.0.2 or 9.0.4 to OracleBI Discoverer Version 10.1.2, use the OracleAS Upgrade Assistant (for more information about using the OracleAS Upgrade Assistant, see Section B.6, "How to upgrade from Discoverer Version 9.0.2/9.0.4")
if you are upgrading from Discoverer Version 4.1 to OracleBI Discoverer Version 10.1.2, you manually copy preference files (for more information, see Section B.7, "How to upgrade from Discoverer Release 4.1")
