A Oracle BI Discoverer Configuration Files

This appendix provides reference information about Discoverer configuration files, and contains the following topics:

A.1 Discoverer File Locations

This section lists the locations of files that are used to configure Oracle BI Discoverer.

Many of the settings in the configuration files are configured by using Fusion Middleware Control. Where possible, use Fusion Middleware Control to configure Discoverer. If you update settings in the configuration files manually, you must only do so in accordance with the instructions in this guide.

Table A-1 shows the locations of the Discoverer configuration files on UNIX. For Windows, replace the slashes (/) in the path with backslashes (\).

Table A-1 Discoverer File Locations

File name Description and location

applypreferences.sh/.bat

This file updates the Discoverer Preferences component (Windows specific).

Location: ORACLE_INSTANCE/Discoverer/Discoverer_instance-name/util/

Note: Information about processing errors is stored in error.txt.

checkdiscoverer.sh/.bat

This file starts a utility that checks the configuration of the Discoverer middle tier, checks the status of the middle-tier components, and reports any failures or anomalies.

Location: ORACLE_INSTANCE/Discoverer/Discoverer_instance-name/util/

Note: Documentation about the checkdiscoverer utility is available in the \util directory.

collectlogs.sh/.bat

This script collects all Discoverer logs into a folder.

Location: ORACLE_INSTANCE/Discoverer/Discoverer_instance-name/util/

Note: For more information about using the collectlogs script, see Section 11.5, "How to copy Discoverer log files."

configuration.xml

This file stores configuration settings for Discoverer.

Location: DOMAIN_HOME/config/fmwconfig/servers/WLS_DISCO/applications/discoverer_discoverer_version/configuration/

Note: Do not edit this file manually. For more information, see Appendix A, "Configuration settings in configuration.xml."

convertreg.pl

This script converts a reg_key.dc file to change the format of integer values (for example, from BigEndian format to LittleEndian format). Use this script to migrate a Discoverer installation from one platform to another platform (for example, from Windows to Solaris).

Location: ORACLE_HOME/perl/bin/

For more information, see Section 9.8, "About migrating Discoverer preferences."

defaults.txt

This file stores factory-supplied default Discoverer preferences. If pref.txt becomes corrupted, you can use defaults.txt to restore default preference settings.

Location: ORACLE_INSTANCE/config/PreferenceServer/Discoverer_instance-name/

dis51pr.exe/dis51pr

This file runs the command line utility used to manage preferences stored in the reg_key.dc file.

Location: ORACLE_HOME/bin/

discenv.sh

This script file sets environment variables used by other Discoverer scripts.

Location: ORACLE_INSTANCE/Discoverer/Discoverer_instance-name/util/

error.txt

This file contains information about processing errors collected when you update the Discoverer Preferences component using the applypreferences script. If error.txt is not present, no errors have been logged.

Location: ORACLE_INSTANCE/config/PreferenceServer/Discoverer_instance-name/

httpd.conf

This file contains configuration information (for example, the Web server timeout setting Timeout) about the Web server used by Oracle BI Discoverer.

Location: ORACLE_INSTANCE/config/OHSComponent/ohs-comp-name/

mod_osso.conf

This file stores configuration settings for Oracle Single Sign-On (for example, settings to turn Oracle Single Sign-On on and off).

Location: ORACLE_INSTANCE/config/OHSComponent/ohs-comp-name/moduleconf/

For more information about enabling Single Sign-On, see Section 13.8.1.2, "How to enable and disable Single Sign-On for Discoverer."

opmn.xml

This file stores the OPMN configuration settings for Discoverer (for example, server timeout, maximum number of Discoverer sessions).

Location: ORACLE_INSTANCE/config/OPMN/opmn-component-name/

opmnctl.sh/.bat

This script file is used to manage OPMN processes.

Location: ORACLE_INSTANCE/bin/

Note: To view online help for this script, type opmnctl help.

pref.txt

This file stores the Discoverer middle-tier preferences, and is used to generate the reg_key.dc file. On installation, this file is populated using settings in the defaults.txt file. If pref.txt becomes corrupted, you can copy preferences in defaults.txt to pref.txt to restore the default preference settings.

Location: ORACLE_INSTANCE/config/PreferenceServer/Discoverer_instance-name/

Note: Do not edit this file manually. Contact Oracle Support for assistance. If you edit the pref.txt file manually, you must run the applypreferences script to apply the preference changes you have made, and then stop and restart the Discoverer preferences server component. For more information, see Section 4.3, "How to start, stop, and restart the Discoverer preferences server component using opmnctl."

reg_key.dc

This file stores individual preferences for each user as a unique combination of database and user ID. These values override global default values specified in pref.txt.

Note: Do not edit this file manually. Contact Oracle Support for assistance. For more information, see Section A.2, "Configuration settings in configuration.xml". The reg_key.dc is a hidden file; that is, the file name is prefixed with a period (.). Ensure that your file manager program or command console can list hidden files (for example, in UNIX, use the console command ls -al to list hidden files).

Location: ORACLE_INSTANCE/config/PreferenceServer/Discoverer_instance-name/

tnsnames.ora

This file contains the names and aliases of all the databases that users can access using Oracle BI Discoverer.

Location: ORACLE_INSTANCE/config/

web.xml

This file contains deployment information about the Discoverer servlets.

Location: DOMAIN_HOME/servers/WLS_DISCO/tmp/_WL_user/discoverer_discoverer_version/random-directory-name/war/WEB-INF/

Note: Do not edit this file manually.


A.2 Configuration settings in configuration.xml

The configuration.xml file stores configuration settings for Discoverer. Table A-2 shows the settings defined in the configuration.xml file.

Note: Do not edit this file manually unless you are following instructions in this guide. You typically use pages in Fusion Middleware Control to configure settings in this file.

To change the Discoverer Portlet Provider settings, use the Discoverer Portlet Provider Configuration page in Oracle Fusion Middleware Control. For more information, see Section 4.6.1, "How to configure Discoverer client-tier components."

Table A-2 Configuration Settings

Setting Description

enableAppsSSOConnection

Specifies whether authenticated Oracle Single Sign-On users using an SSO-enabled Oracle Applications database can create and use Discoverer private connections without entering a password (for more information, see Section 14.2.2, "How to enable Oracle Applications users to create or use private connections to SSO-enabled Oracle Applications databases").

Note: You set the value using the Allow authenticated Oracle Single Sign-On (SSO) users to create and use private connections to SSO-enabled Oracle Applications databases, without entering a password check box on the Discoverer Administration page in Oracle Fusion Middleware Control.

/disco:configuration/viewer/pageNavigation

Specifies whether the page navigation tool is displayed in Discoverer Viewer. Valid values are:

  • TRUE

    When the value of this setting is set to TRUE, the page navigation tool is displayed in worksheets.

    When the page navigation tool is displayed, query results are returned to the worksheet non-incrementally (all together). This might reduce performance when displaying large data sets the first time it is rendered.

  • FALSE

    When the value of this setting is set to FALSE, the page navigation tool is not displayed in worksheets.

    When the page navigation tool is not displayed, query results are returned to the worksheet incrementally (in chunks). This improves performance when displaying large data sets.

Note: You set the value using the MBean Browser in Oracle Fusion Middleware Control.

GraphAxisAutoScaledFromZero

Specifies whether Discoverer Viewer (only when used with a multidimensional data source) displays graph scaled from zero or values based on the worksheet data. Valid values are:

  • TRUE

    When the value of this setting is TRUE, all the graph axes in Discoverer Viewer scales from zero only. The default value of this setting is TRUE.

  • FALSE

    When the value of this setting is FALSE, the graph axes in Discoverer Viewer start the scale based on the worksheet data.

Note: You set the value using the System MBean Browser in Oracle Fusion Middleware Control.

EnableLevelOffsetBasedTimeCalc

Specifies the kind of calculation templates that Discoverer Plus OLAP users see. By default, this setting is TRUE, so that users see the level-offset based templates that are new to Release 11.1.1 when they create a calculation or edit a calculation that was created with those templates. They see the calendar-based templates from Release 10.1.2 when they edit a calculation that was created with those templates. You can change the default to use the Release 10.1.2 templates if the time hierarchy is modeled on the Gregorian calendar

Add this setting within the <plus> tag, directly after the <enablePlus> tag.

ExcludeDuplicateRowsDuringExcelExport

Specifies whether duplicate rows are filtered when you export a worksheet from Discoverer Plus OLAP to Microsoft Excel. Valid values are:

  • TRUE

    Duplicate rows are not shown in the Microsoft Excel report.

  • FALSE

    Duplicate rows are shown in the Microsoft Excel report.

ExcludeDuplicateColumnsDuringExcelExport

Specifies whether duplicate columns are filtered when you export a worksheet from Discoverer Plus OLAP to Microsoft Excel. Valid values are:

  • TRUE

    Duplicate columns are not shown in the Microsoft Excel report.

  • FALSE

    Duplicate columns are not shown in the Microsoft Excel report.

SortMemberStepHierarchically

Specifies whether Member Steps are sorted hierarchically in Discoverer Plus OLAP. When this option is disabled, members are sorted in the order in which they are added, rather than in hierarchical order. Valid values are:

  • DEFAULT

    Always sort members hierarchically and do not display the Sort Members Hierarchically check box in the Edit Member Step dialog.

  • YES

    Sort members hierarchically, display the Sort Members Hierarchically check box in the Edit Member Step dialog, and have the box checked by default. Users can deselect the box to not use hierarchical order.

    YES is the default value for this parameter when Discoverer Plus OLAP is first installed.

  • NO

    Sort members in the order of selection, display the Sort Members Hierarchically check box in the Edit Member Step dialog, and have the box unchecked by default. Users can check the box to use hierarchical order.

Add this setting within the <plus> tag, directly after the <enablePlus> tag.

SwitchWorksheetBehaviour

Specifies the Discoverer Viewer behavior if an end user opens a different worksheet when they have made changes to the current worksheet. Valid values are:

  • always_save

    When switching worksheets within a workbook, save changes to the worksheet (that is, save the whole workbook) without prompting the end user to confirm.

  • never_save

    When switching worksheets within a workbook, discard changes to the worksheet without prompting the end user to confirm.

  • prompt

    When switching worksheets within a workbook, prompt the user to select either save, cancel, or discard changes to the worksheet.

Note: If this setting is not present in the file, Discoverer defaults to 'prompt'.

worksheetSaveBehavior

Specifies the Discoverer Viewer saving behavior when the user navigates away from a worksheet after making some changes in it. Note that this parameter is not effective when you switch between worksheets. This setting is done in the <viewer> section of the configuration.xml file. Valid values are:

  • always_save

    When navigating from a worksheet, save changes to the worksheet without prompting the end user to confirm.

  • never_save

    When navigating from a worksheet, discard changes to the worksheet without prompting the end user to confirm.

  • prompt

    When navigating from a worksheet, prompt the user to select either save, cancel, or discard changes to the worksheet.

Note: If this setting is not present in the file, Discoverer defaults to 'prompt'.

propagateGUIDToVPD

Specifies whether the GUID or the Oracle Single Sign-On user name is passed into Virtual Private Database (VPD) policies. Valid values are:

  • TRUE

    When the value of this setting is set to TRUE, the GUID is propagated to VPD policies.

  • FALSE

    When the value of this setting is set to FALSE, the SSO User Name is propagated to VPD policies.

Note: You set the value using the User ID field in the Discoverer Administration page in Oracle Fusion Middleware Control.

pickerCompatibleVersions

Specifies whether the Date or Color pickers are available on the Portal. To make these pickers available for different versions of Portal, change this parameter to the respective Portal version.

For example, to view the Date or Color pickers on 10.1.4 Portal, change the value of pickerCompatibleVersions to "10.1.4".

isCurrentPageItemsExportForOLAP

Specifies how Discoverer Viewer exports worksheets of OLAP data that have page items when you export to Microsoft Excel or to HTML. Valid values are:

  • TRUE

    Exports a worksheet of OLAP data to Microsoft Excel or to HTML with the current set of page items.

  • FALSE

    Exports all possible combinations of page items to Microsoft Excel or to HTML.

This optional setting is present in the <viewer> section of the configuration.xml file with default value as FALSE.

cacheThreshold

Specifies the number of cache entries maintained in the infrastructure database and improves the display of portlet data as the user changes parameter values. You can set this value in the <portlet> section of the configuration.xml file.

Default value for this setting is "1". In this case, Discoverer Portlet Provider maintains only the previous cache entry in addition to the results for the current combination of values.

Note: When you set cacheThreshold to a value higher than 1, it can increase the amount of space consumed in the infrastructure database and the amount of time required for each portlet to refresh. For example, with cacheThreshold="15", at refresh time, the query for the portlet might run 15 times and that the DB space needed to store the results is 15 times greater. You must set cacheThreshold judiciously and ensure that portlet refreshes are completed within a reasonable time.

viewerURLForPublicUser

Specifies the behavior when you click the Analyze link on a public Portal page. When you specify the value of this setting as "normalViewer", clicking the Analyze link takes you to Discoverer Viewer. This setting is defined in the <portlet> section of the configuration.xml file.

Note that if the user logs into Portal or SSO then the Analyze link always open the Single Worksheet Viewer irrespective of the setting in configuration.xml file.

enableDataSelection

Specifies whether Discoverer Viewer enables you to select data in a table and copy it to clipboard as in an HTML page. Valid values are:

  • TRUE

    Enables column selection in the table and disables data selection for copying to clipboard.

  • FALSE

    Disables the column selection in the table and enables you to select and copy data to a clipboard.

This optional setting is present in the <viewer> section of the configuration.xml file with default value as TRUE.

numberOfLOVsToBeDisplayed

Specifies the number of values to be displayed in the list box of the parameter search dialog.

This optional setting is present in the <viewer> section of the configuration.xml file. The default value of this setting is 25.

numColsForLOW

Specifies the number of columns to be displayed for the List of Worksheet portlet when it is opened in Single Worksheet Viewer.

This optional setting is present in the <portlet> section of the configuration.xml file. The default value is 6. If you specify the value of this setting as '0', all columns from the worksheet are displayed.

numRowsForLOW

Specifies the number of rows to be displayed for the List of Worksheet portlet when it is opened in Single Worksheet Viewer.

This optional setting is present in the <portlet> section of the configuration.xml file. The default value is 25. If you specify the value of this setting as '0', all rows from the worksheet are displayed.

peekSleepIntervalSec

Specifies the sleep interval for retrieving scheduled portlets to be refreshed. The default value of this parameter is 2 seconds.

Note: If there is more than one middle tier, for load balancing scheduled portlets, you can specify different values for this parameter in each of the middle tiers. The scheduled refreshes are then distributed more evenly among the middle tiers.


A.3 Configuration settings in opmn.xml

The opmn.xml file stores OPMN settings for Discoverer. Table A-3 shows the settings in opmn.xml that you might change if you need to modify the default Discoverer configuration:

Table A-3 Configuration settings in opmn.xml

Setting Description

FND_SECURE

Specifies the directory containing a DBC file that Discoverer uses to connect to an Oracle Applications database in secure mode.

Discoverer first attempts to find a DBC file with the file name databasename.dbc. If not found, Discoverer then attempts to use a file with the file name hostname_SID.dbc.

If this value is not set, Discoverer attempts to use the value specified by FND_TOP.

FND_TOP

Specifies the directory path for the secure directory containing a DBC file that Discoverer uses to connect to an Oracle Applications database in secure mode (that is, $<FND_TOP>/secure).

This variable is included for backward compatibility. Discoverer first attempts to use the value specified by FND_SECURE.

ORBDebug

Specifies whether Discoverer instructs the ORB to print debugging messages from the server configurator network. This option does not have a value, but is used as a toggle to enable or disable debugging messages.

ORBDebugLevel=<level>

Specifies the level of debugging in the ORB. The range is 1 for the minimum amount of debugging information to 10 for the maximum amount of debugging information.

ORBLogFile=<name of log file>

Specifies that all ACE_DEBUG and ACE_ERROR messages are redirected to the file specified. If you do not specify a path, the file is created in the directory in which the server is running (for example, $ORACLE_HOME).

ORBObjRefStyle=[IOE|URL]

Specifies the user-visible style of object references. The IOR style (default) is the conventional CORBA object reference, whereas the URL style looks more like a URL.

ORBVerboseLogginglevel=[0|1|2]

Specifies the amount of status data printed on each line of the debug log. Higher numbers generate more output.


Note: The ORB element is not included by default. If you want to customize the TAO ORB, add the ORB elements and attributes as described in Table A-2. For more information, see the TAO documentation.
