13 Starting OracleBI Discoverer using URL parameters

Note: This chapter only applies to Discoverer Plus and Discoverer Viewer. For more information about configuring Discoverer Plus OLAP, see Chapter 6, "Configuring the Discoverer Catalog and Discoverer Plus OLAP".

This chapter explains how to use OracleBI Discoverer with URL parameters, and contains the following topics:

13.1 Why use Discoverer with URL parameters

Discoverer end users usually start OracleBI Discoverer by manually choosing a Discoverer connection (or connecting directly), opening a worksheet, and optionally specifying workbook parameter values. To speed up this process, you can create a URL with parameters to start OracleBI Discoverer with specific settings (e.g. login details, workbook ID, worksheet ID, parameter values). For example, you might want to provide a URL to Discoverer end users that automatically logs into Discoverer and opens a particular worksheet. For examples of Discoverer URL parameters, see Section 13.5, "Examples of using URL parameters".

Having created a URL that meets your requirements, you can:

13.2 What is the URL parameter syntax?

URL parameters must conform to the following syntax:

http://<host.domain>:<port>/<Discoverer application name>? arg1=value1...&argN=valueN

where:

Notes:

13.2.1 About URL parameters and format masks

When specifying format masks for dates and numbers, note the following:

  • Discoverer uses the format mask specified when the workbook was created in Discoverer Desktop or Discoverer Plus.

  • If numeric and date items in a worksheet have 'default' as the format mask value, Discoverer uses the default format mask in the specified browser environment, unless optional URL parameters are specified.

  • If optional URL parameters for the format masks are not provided, Discoverer will use the format mask specified when the EUL was created (e.g. using Discoverer Administrator).

13.2.2 About using URL parameters with private connections

When you specify connection information in URL parameters, note the following restrictions:

  • If Discoverer end users are not allowed to create private connections in Discoverer Plus or Discoverer Viewer, you can only use URL parameters containing public connection information. In other words, you must include the connection ID in a URL parameter string for a public connection because end users can only start Discoverer using public connections.

  • If a Discoverer URL parameter string does not work, it might be because you are trying to use a private connection when private connections are not allowed. In other words, the Allow users to define and use their own private connections in Discoverer Plus and Discoverer Viewer check box is cleared in the Discoverer Configuration page in Application Server Control.

    Discoverer end users should navigate to the required Discoverer worksheet and store the URL as a bookmark in their browser.

    For more information about the Allow users to define and use their own private connections in Discoverer Plus and Discoverer Viewer check box in Application Server Control, see Section 4.5, "About specifying whether Discoverer end users can create their own private connections".

    For more information about connection IDs, see the cn=URL parameter in Section 13.7, "Discoverer Plus and Viewer URL parameters".

13.3 How to specify login information using a public connection

When you specify login details on a URL, you cannot specify the database password as a URL parameter. The Discoverer end user is always prompted for a password, unless you specify the connection ID of a public connection. A public connection is a set of login details created and maintained by Discoverer middle tier managers. For an example of using a connection ID, see Section 13.5.4, "Example 4: Starting Discoverer without exposing a password in the URL".

Note: To use public connections, the OracleBI installation must be associated with an OracleAS infrastructure (for more information, see Chapter 2, "Associating an OracleBI installation with an OracleAS infrastructure").

To specify login information using a public connection:

  1. If a public connection is not available, create a public connection using login details that access the worksheet you want to open (for more information, see Section 4.6, "How to create public connections").

  2. Find out the connection ID of this public connection (for more information, see Section 13.4.3, "How to find out the connection ID of a connection").

    For example, a connection ID might be 'cf_a156'.

  3. Create a URL using the cn= URL parameter, as follows:

    http://<host.domain>:<port>/discoverer/viewer?cn=<connection ID value>

    For example, if the connection ID is cf_a156, create a URL parameter as follows:

    http://<host.domain>:<port>/discoverer/viewer?cn=cf_a156

    The Discoverer end user will not be prompted for a database password when using this URL to start Discoverer.

13.4 About specifying workbooks and worksheets using URL parameters

When using URL parameters to specify workbooks and worksheets, you can use either unique IDs (recommended), or the workbook name or worksheet name.

Hint: To avoid encoding problems and problems caused by long workbook or worksheet names, Oracle recommends that you use unique IDs to specify workbooks and worksheets (for more information, see Section 13.4.1, "How to find out the unique workbook ID of a workbook" and Section 13.4.2, "How to find out the unique worksheet ID of a worksheet").

Note: Discoverer Plus OLAP only uses workbook names and worksheet names to identify workbooks and worksheet. For more information, see Section 6.7, "URL parameters for the Discoverer Plus OLAP Servlet".

The following table shows which URL parameters are used to specify Discoverer workbooks and worksheets.

Specifying a workbook using a URL parameter Specifying a worksheet using a URL parameter
In Discoverer Plus, use opendbid= <workbook ID>

(or use opendb= <workbook name> for backwards compatibility)

In Discoverer Plus, use sheetid= <worksheet ID>

(or use sheet= <worksheet name> for backwards compatibility)

In Discoverer Viewer, use wbk= <workbook ID>

(or use wb= <workbook name> for backwards compatibility)

In Discoverer Viewer, use wsk= <worksheet ID>

(or use ws= <worksheet name> for backwards compatibility)

In Discoverer Plus OLAP, use workbook= <workbook name> In Discoverer Plus OLAP, use worksheet= <worksheet name>

Notes

13.4.1 How to find out the unique workbook ID of a workbook

You find out the unique workbook ID of a workbook so that you can specify a workbook on a Discoverer URL using its unique workbook ID.

Note: You identify a workbook using its workbook ID in preference to using its workbook name to avoid encoding problems and problems caused by large workbook names (for more information, see Section 13.4, "About specifying workbooks and worksheets using URL parameters").

To find out the unique ID of a workbook in Discoverer Plus:

  1. Start a Web browser.

  2. Run Discoverer Plus and open a worksheet in the workbook.

  3. Choose File | Manage Workbooks | Properties to display the Workbook Properties dialog.

  4. To find out the unique ID of a workbook, look at the value in the Identifier field.

Notes

  • You can use a workbook ID value to specify a workbook as follows:

13.4.2 How to find out the unique worksheet ID of a worksheet

You find out the unique worksheet ID of a worksheet so that you can specify a worksheet on a Discoverer URL using its unique worksheet ID.

Note: You identify a worksheet using its worksheet ID in preference to using its worksheet name to avoid encoding problems and problems caused by large worksheet names (for more information, see Section 13.4, "About specifying workbooks and worksheets using URL parameters").

To find out the unique ID of a worksheet in Discoverer Plus:

  1. Start a Web browser.

  2. Run Discoverer Plus and open the worksheet.

  3. Choose Edit | Worksheet Properties to display the Worksheet Properties dialog.

  4. Display the General tab and look at the value in the Identifier field.

Notes

  • You can use a worksheet ID value to specify a worksheet as follows:

13.4.3 How to find out the connection ID of a connection

You find out the connection ID (sometimes referred to as a connection key) of a connection so that you can specify a connection using the key URL parameter. For example, you might want to start Discoverer without exposing a password in the Discoverer URL (for more information, see Section 13.5.4, "Example 4: Starting Discoverer without exposing a password in the URL").

You can find out the connection ID of a connection in either Discoverer Viewer or Discoverer Plus.

To find out the connection ID of a connection:

  1. Start a Web browser.

  2. Start Discoverer to display the connections containing the connection that you want to use, as follows:

    • if you use Discoverer Viewer, display the Connect to Discoverer Viewer page

    • if you use Discoverer Plus, display the Connect to Discoverer Plus page

    The example below shows the Connect to Discoverer Plus page.

    Description of connect.gif follows
    Description of the illustration connect.gif

  3. In the Details column, select the Show link next to the connection to expand the connection details.

    Hint: The Show links are not available in Netscape Navigator. Use Microsoft Internet Explorer to display the connection page.

  4. Note down the value of Connection Key.

    You can now use the value of Connection Key with the cn= URL parameter. For more information, see Section 13.3, "How to specify login information using a public connection".

Notes

13.5 Examples of using URL parameters

This section contains the following examples of using URL parameters with Discoverer:

Note: Examples 1 to 4 use a public connection to specify login details. The public connection in these examples has the ID value cf_a156. Example 5 specifies login details using us=, db=, and eul=). Example 6 uses s public connection to an OLAP data source.

For information about how to create a public connection, see Section 4.6, "How to create public connections").

13.5.1 Example 1: Starting Discoverer Viewer using URL parameters

To start Discoverer Viewer, connect automatically as jchan, and open a worksheet called January Analysis in a workbook called Monthly Analysis, you might use the following URL:

http://<host.domain>:<port>/discoverer/viewer?cn=cf_a156&wbk=MONTHLY_ANALYSIS&wsk=179

Notes

13.5.2 Example 2: Starting Discoverer Viewer using URL parameters

To start Discoverer Viewer, connect automatically as jchan to the Sales EUL, open a worksheet called January Analysis in a workbook called Monthly Analysis, and enter the worksheet parameter value East, you might use the following URL:

Notes

13.5.4 Example 4: Starting Discoverer without exposing a password in the URL

To start Discoverer Viewer using a connection called Sales Data that has the connection ID cf_a157, you might use the following URL:

http://<host.domain>:<port>/discoverer/viewer?cn=cf_a157

Notes

13.5.5 Example 5: Starting Discoverer Viewer and prompt for a password

In this example, you want end users to be prompted to specify a password before they can access Discoverer. You therefore specify a a username, database, and EUL on the URL.

To start Discoverer Viewer, connect automatically as video5, and open a worksheet called January Analysis in a workbook called Monthly Analysis, you might use the following URL:

http://<host.domain>:<port>/discoverer/viewer?us=video5&db=db1&eul=VIDEO5&wbk=MONTHLY_ANALYSIS&wsk=179

Notes

13.5.6 Example 6: Starting Discoverer Plus OLAP

To start Discoverer Plus OLAP, you might use the following URL:

http://<host.domain>:<port>/discoverer/plus?db=host1:1521:ora925

Notes

13.5.7 Example 7: Starting Discoverer Plus and opening a scheduled workbook

To start Discoverer Plus, connect automatically as jchan to the Sales EUL, and open a scheduled workbook, you might use the following URL:

http://<host.domain>:<port>/discoverer/plus?cn=cf_a156&opendbid=SALES_ANALYSIS2&sheetid=42&workbooksource=Scheduled

Notes

  • http://<host.domain>:<port>/discoverer/plus? is the Discoverer Viewer URL.

  • cn=<value> specifies the connection ID of a Discoverer connection.

    For more information about finding out connection IDs, see Section 13.4.3, "How to find out the connection ID of a connection".

  • opendbid=<value> specifies the workbook ID of a Discoverer scheduled workbook.

  • sheetid=<value> specifies the worksheet ID of a Discoverer scheduled worksheet.

  • workbooksource=Scheduled identifies the workbook as scheduled.

  • To open a scheduled workbook in Discoverer Viewer, specify the workbook ID (e.g. using wbk=), the results number (e.g. 3), and the worksheet ID (e.g. using wsk=). For example, to open results number 1 for a scheduled workbook, you might use the following URL:

    http://<host.domain>:<port>/discoverer/viewer?cn=cf_a156&wbk=MONTHLY_ANALYSIS&3&wsk=179

    Hint: To obtain the results number, display the Scheduling Manager dialog in Discoverer Plus (i.e. choose Tools | Manage Schedules), expand the scheduled workbook, and note down the results number of the worksheets processed.

13.8 Discoverer Plus URL parameters

This table describes Discoverer Plus-specific URL parameters that can be used in addition to the generic URL parameters in Section 13.7, "Discoverer Plus and Viewer URL parameters".

Hint: Do not use Discoverer Plus URL parameters on the same URL as Discoverer Viewer URL parameters.

Note: For information about Discoverer Plus OLAP URL parameters, see Chapter 6, "Configuring the Discoverer Catalog and Discoverer Plus OLAP".

Parameter and Values Description Example
_plus_popup=<true or false> Specifies whether to launch Discoverer Plus in a new browser window or in the Discoverer Connections page, as follows:
  • true (default) launches Discoverer Plus in a new browser window.

  • false launches Discoverer Plus in a the current browser window.

This URL parameter can be used in conjunction with framedisplaystyle (for more information, see framedisplaystyle=).

_plus_popup=true

database=<database name or alias> Specifies which database to connect to when Discoverer starts.

Hint: You can also use the connect URL parameter to specify a database, user name, and password as a single parameter.

database=mydb
framedisplaystyle=<separate or embedded> Specifies how to launch the Discoverer main window.
  • use 'separate' to launch Discoverer's main as a separate frame from the browser (i.e. from the Discoverer Connections list). The browser window contains a Discoverer image and must remain open while Discoverer is being used.

  • use 'embedded' to launch Discoverer's main window within the current browser window.

Note: To deploy Discoverer Plus in conjunction with a screen-reader (e.g. JAWS), set the value to 'separate'. For more information about accessibility and Discoverer, see "Using the JAWS screen reader with Discoverer".

When using _pop_up in conjunction with framedisplaystyle=, the possible combinations are:

  • _plus_popup=true and framedisplaystyle=embedded launches Discoverer Plus in a new pop-up browser window that contains the Plus applet embedded in it.

  • _plus_popup=true and framedisplaystyle=separate opens a new pop-up browser window and launches Discoverer Plus in a new applet window.

    This combination launches three windows: the original browser window (i.e. Discoverer connections page), the new browser window containing the Discoverer image, and the JFrame window containing the Discoverer Plus applet.

  • _plus_popup=false and framedisplaystyle=embedded launches Discoverer Plus in the current browser window

  • _plus_popup=false and framedisplaystyle=separate launches Plus in a JFrame window. The current browser window contains the Discoverer image.

framedisplaystyle=separate
helpset=<path>/<locale>/<HS file> Specifies a different help set location that is different to the default Discoverer Plus help set.

Note: The help must be in sub-directories named by its standard two character locale.

Hint: As an alternative to using the HelpSet URL parameter to customize the help, edit plusug.hs and its related files.

locale=Plus_files/My_custom_help

(i.e. where the Plus_files/My_custom_help directory contains the language folders, e.g. /en, /es, /fr).

lookandfeelname=<system or oracle or browser or plastic or <custom> Specifies a browser look and feel. For example, a user might want to run Discoverer Plus using the Windows look and feel.

This setting overrides the LAF specified in Oracle Application Server Control (for more information, see Section 9.1.3, "How to change the Discoverer Plus/Plus OLAP LAF for all end users").

If you specify the lookandfeelname value as 'custom', Discoverer uses the LAF class and JAR specified in the configuration.xml file.

For more information about specifying a custom LAF on the Discoverer middle tier, see Section 9.1.4, "How to define a custom LAF for Discoverer Plus/Plus OLAP").

lookandfeelname=plastic
opendb=<workbook name> Specifies the name of a workbook to open (Discoverer assumes that the workbook is stored in the database, not as a scheduled workbook). If you use the opendb parameter more than once in the URL, Discoverer uses the last one.

Hint: This URL parameter is included for backward compatibility. Oracle recommends that you use opendbid to specify workbooks.

Note: 'opendb=Video+Sales+Workbook' is the equivalent of 'workbookname=Video+Sales+Workbook&workbooksource=Database'.

See also workbookname and workbooksource.

opendb=Video+Sales+Workbook

Note: You also need to specify a workbook source (i.e. workbooksource=Database or Scheduled). E.g. workbooksource=Scheduled&opendb=Video+Sales+Workbook.

opendbid=<unique ID> Specifies the unique ID of the workbook you want to open.

Discoverer assumes that the workbook is stored in the database, not as a scheduled workbook.

For more information about how to find the unique ID of a workbook, see Section 13.4.1, "How to find out the unique workbook ID of a workbook".

For examples, see Section 13.5, "Examples of using URL parameters".

opendbid=JanuarySales

Note: You also need to specify a workbook source (i.e. workbooksource=Database or Scheduled). E.g. workbooksource=Scheduled&opendbid=JanuarySales.

param_<parameter_name>=<parameter_value> Specifies values for parameters.

Note: If the workbook does not contain a parameter of that name, Discoverer ignores the parameter.

param_regionparam=East
responsibility=<responsibility name> Specifies the Oracle Applications responsibility for Oracle Applications end users.

Note: If you do not specify a user name, password, responsibility, or security group, the Discoverer end user is prompted to enter the missing login information.

responsibility=Manager

(i.e. Discoverer bypasses the Responsibility dialog and assigns the end user an Oracle Applications responsibility of Manager)

sheet=<worksheetname> Specifies the name of the worksheet to open by default.

Note: If you use the sheet parameter more than once in the URL, Discoverer opens the last one.

Hint: This URL parameter is included for backward compatibility. Oracle recommends that you use sheetid to specify worksheets.

sheet=Sales+Detail+Sheet
sheetid=<unique ID> Specifies the unique identifier of the worksheet to open.

For more information about how to find the unique ID of a worksheet, see Section 13.4.2, "How to find out the unique worksheet ID of a worksheet".

Note: You must also specify a workbook using opendbid.

For examples, see Section 13.5, "Examples of using URL parameters".

sheetid=7
username=<database user name> Specifies a database user name with which to connect to Discoverer.

Hint: You can also use the connect parameter to specify a database, user name, and password as a single parameter.

Note: If you do not specify a user name, password, responsibility, or security group, the Discoverer end user is prompted to enter the missing login information.

username=video_user
windowheight=<number of pixels> Specifies the height in pixels of the Discoverer application frame. If you do not use this parameter, Discoverer uses a default value. windowheight=600

windowwidth=<number of pixels> Specifies the width in pixels of the Discoverer application frame. If you do not use this parameter, Discoverer uses a default value. windowwidth=800

workbookname=<workbookname> Specifies the name of the Discoverer workbook to open.

Hint: Use this URL parameter in conjunction with workbooksource. E.g. 'workbookname=Video+Sales+Workbook&workbooksource=Database' is the equivalent of 'opendb=Video+Sales+Workbook'.

Hint: This URL parameter is included for backward compatibility. Oracle recommends that you use opendbid to specify workbooks.

workbookname=Video+Sales+Workbook

workbooksource=<Database or Scheduled> Specifies the location of the workbook to open:
  • Database specifies that the workbook is saved in the database.

  • Scheduled specifies that the workbook is a scheduled workbook that is updated periodically.

Hint: Use this URL parameter in conjunction with opendbid or workbookname.

workbooksource=Database


13.9 Discoverer Viewer URL parameters

This table describes Discoverer Viewer-specific URL parameters that can be used in addition to the generic URL parameters in Section 13.7, "Discoverer Plus and Viewer URL parameters".

Hint: Do not use Discoverer Viewer URL parameters on the same URL as Discoverer Plus URL parameters.

Note: These URL parameters do not apply to worksheets created in Discoverer Plus OLAP.
