For more information about installing Oracle Application Server, see the Oracle Application Server Installation Guide.

Notes

• Before users can use Discoverer to analyze data, the database must contain a Discoverer EUL Version 5.0.2 or higher. The Discoverer manager must have created or updated the End User Layer (EUL) Version 5.0.2 with Oracle Discoverer Administrator Version 9.0.4 or later (shipped as part of Oracle Developer Suite).

• You can use the checkdiscoverer utility to verify a Discoverer configuration and report on failures or anomalies (for more information about the checkdiscoverer utility, see Section 4.11.2, "What is the checkdiscoverer utility?").

• In some circumstances you might want to remove the Discoverer Plus applet from a client machine. For example, to provide a clean environment in which to run Discoverer Plus by removing older versions of Discoverer Plus. The location of the Discoverer Plus applet depends on the version of Windows running on that machine. For example, on Windows 2000, the Discoverer Plus applet is typically located in:

  Windows 2000 - C:\Documents and Settings\<USER>\Oracle Jar Cache

  You might also need to clear the browser's temporary files (e.g. in Internet Explorer, choose Tools | Internet Options and click Delete Files).

2.2 General information about running OracleAS Discoverer

To run Discoverer Viewer, you just need an Internet browser, as follows:

• To run Discoverer Viewer over HTTP, start and Internet browser and enter the Discoverer Viewer HTTP URL (e.g. http://<host.domain>:<HTTP port>/discoverer/viewer).

  For more information, see Section 2.12, "How to run Discoverer Viewer over HTTP".

• To run Discoverer Viewer over HTTPS, start and Internet browser and enter the Discoverer Viewer HTTPS URL (e.g. https://<host.domain>:<HTTPS port>/discoverer/viewer).

  For more information, see Section 2.8, "About running Discoverer over HTTPS".

To run Discoverer Plus, you need an Internet browser, and possibly the following additional software, as follows:

• If the client browser machine does not have a JVM installed (e.g. Oracle JInitiator), you need to install a JVM and initialize the Discoverer Plus applet for that machine. For more information, see Section 2.7, "About running Discoverer Plus over HTTP for the first time on a client machine".

• To run Discoverer Plus over HTTPS, you must have installed a security certificate from a Certificate Authority. For more information, see Section 2.8, "About running Discoverer over HTTPS".

2.3 What are the supported Web browser versions for Discoverer?

The preferred browsers for Discoverer are:

• Windows - Microsoft Internet Explorer versions 5.5 and 6.0 (version 6.0 is the preferred version)

• Windows - Netscape Navigator 4.79 and 6.0

• UNIX - Netscape Navigator 4.7 and 6.0

Discoverer Viewer will also run with Internet Explorer 5.0. However, note the following:

• There are known bugs in Internet Explorer 5.0 which can cause intermittent problems when posting information from Viewer form pages such as the parameter screen.

• Internet Explorer versions prior to 5.5 have a variety of compatibility issues with certain versions of Microsoft Excel. For this reason, customers who use Internet Explorer and the "Export to Excel" feature in Discoverer Plus and Viewer are strongly recommended to use Internet Explorer 5.5 or higher.

  Note: These problems are generic to Internet Explorer and Microsoft Excel and are not specific to their use with Oracle products.

• Performance of the HTML interface for Discoverer Viewer is substantially better with Microsoft Internet Explorer 5.5 and 6.0.

2.4 About restricting how users can run Discoverer

In a secure Discoverer environment you want to enable only authorized end users to access Discoverer. For example, you might want to limit users to read-only access to Discoverer workbooks using Discoverer Viewer.

Depending on your security requirements, you might do any of the following to provide a secure Discoverer environment:

• You might prevent Discoverer users creating their own connections. If you disable private connections, Discoverer end users can only start Discoverer using public connections (i.e. login information) that you specify.

  For more information, see Section 3.6, "About specifying whether Discoverer end users can create their own private connections".

• You might prevent users using Discoverer Plus to modify workbooks. If you disable Discoverer Plus, users only have read-only access to workbooks using Discoverer Viewer.

  You disable Discoverer Plus using Application Server Control (for more information, see Section 4.5, "About disabling and enabling Discoverer client tier components").

• you might run Discoverer Plus in read-only mode for specified Discoverer end users by removing the Create/Edit Query privilege in Oracle Discoverer Administrator (for more information, see Oracle Discoverer Administrator Administration Guide)

• You might enable Oracle Advanced Security (formerly Advanced Security Option) encryption between the middle tier and the database.

For more information about other Discoverer security features, see Section 12.1, "Maintaining security with OracleAS Discoverer".

2.5 Which port number is Discoverer installed on?

When you perform an OracleAS installation of type Business Intelligence and Forms (i.e. a Discoverer installation) Discoverer is installed on port 7777 or the next available port.

For example, an OracleAS infrastructure installation uses port 7777. Therefore, if you have an OracleAS installation of type Business Intelligence and Forms on the same machine as the infrastructure install, Discoverer will typically use a port in the range 7778 - 7877.

Hint: If you are not sure which default ports Discoverer is using, display the OracleAS ports list page (for more information, see Section 4.10, "How to list ports used by OracleAS").

For information about changing default OracleAS ports for Discoverer, see Section 4.10.1, "How to change the port on which Discoverer is deployed".

2.6 What are the memory requirements and privileges required to run Discoverer Plus and Discoverer Viewer?

To run OracleAS Discoverer Plus, you require the following on the Discoverer Plus client machine (i.e. the browser machine):

• administrative privileges on the client machine, because you need to be able to install a Java Virtual Machine (e.g. Oracle JInitiator)

• at least 15KB of Users Personal Profile Space for the Oracle Jar Cache

• a minimum of between 25 - 50 MB of available disk space to install a JVM

To run OracleAS Discoverer Viewer, you need only to be able to run a standard Web browser (e.g. Microsoft Internet Explorer) that has JavaScript and cookies enabled.

2.7 About running Discoverer Plus over HTTP for the first time on a client machine

When you run Discoverer Plus for the first time on a client machine, you perform a one-time setup process to install a Java Virtual Machine (e.g. Oracle JInitiator) and initialize the Discoverer Plus software. This process is typically performed when:

• you have installed OracleAS and want to test that Discoverer is working

• a Discoverer end user wants to run Discoverer Plus for the first time on a client machine

If you upgrade Discoverer, you might have to repeat the setup process. For example, you might install a new version of Discoverer Plus that requires a new version of Oracle JInitiator, or a new version of the applet.

The Discoverer Plus initialization procedure is different for Microsoft Internet Explorer and Netscape Navigator. Refer to the appropriate task below:

• for Microsoft Internet Explorer on a Windows client, see Section 2.9, "How to run Discoverer Plus over HTTP in Microsoft Internet Explorer for the first time on a Windows client machine"

• for Netscape Navigator on a Windows client, see Section 2.10, "How to run Discoverer Plus over HTTP in Netscape Navigator for the first time on a Windows client machine"

• for Netscape Navigator on a UNIX client, see Section 2.11, "How to run Discoverer Plus over HTTP in Netscape Navigator for the first time on a UNIX client machine"

Notes

• If Single Sign-On is enabled, you will first be asked to authenticate as a single sign-on user before a Discoverer connections page is displayed.

• If Single Sign-On is not enabled, Discoverer end users are asked to enter a database password when they select a private connection.

  Note: A Discoverer connection stores login information.

• To run Discoverer Plus in Microsoft Internet Explorer, you must have the Security level set no higher than 'Medium' or custom equivalent (i.e. using the Security dialog in Microsoft Internet Explorer).

• If a Security Warning dialog is displayed when you run Discoverer, click Yes to install and run the JVM (e.g. Oracle JInitiator). If you have previously configured the machine to always trust content from Oracle Corporation, this dialog is not displayed.

Figure 2-1 Security Warning dialog

Text description of the illustration jinit1.gif

Note: Discoverer Viewer requires no additional software to be installed on the client machine.

• If the Discoverer initialization takes longer than the session timeout (e.g. you might be accessing Discoverer over a 56K dial-up connection), increase the Timeout value in the pref.txt file on the middle tier and apply the preferences. For more information, see Section 8.8, "List of Discoverer user preferences".

• The steps in Section 2.9, "How to run Discoverer Plus over HTTP in Microsoft Internet Explorer for the first time on a Windows client machine" and Section 2.10, "How to run Discoverer Plus over HTTP in Netscape Navigator for the first time on a Windows client machine" assume that you are using the Jinitiator Java Virtual Machine (JVM). If you are using a different JVM, the installation steps might differ slightly.

2.8 About running Discoverer over HTTPS

Before you can run Discoverer over HTTPS (i.e. in Secure Sockets Layer (SSL) mode), you must have installed a security certificate from a Certificate Authority (e.g. Verisign) on the Oracle HTTP server on the OracleAS instance. For more information about installing security certificates, see Oracle Application Server Administrator's Guide and Oracle Application Server Security Guide.

An OracleAS installation includes a dummy certificate on the OracleAS instance that you can use to confirm that HTTPS is deployed. You must install a valid security certificate to make sure that communication with the OracleAS instance is secure.

A security certificate confirms to the Discoverer client machine that the holder of the security certificate is who they say they are.

How to run Discoverer over HTTPS is different for Discoverer Viewer and Discoverer Plus, as follows:

• To run Discoverer Viewer over HTTPS, simply specify HTTPS on the Discoverer Viewer URL.

  For example:

  https://<host.domain>:4443/discoverer/viewer

  When the Security Alert dialog is displayed, click Yes to accept the security certificate issued by the certificate authority you are using. Discoverer Viewer then starts in HTTPS mode. For more information about starting Discoverer Viewer, see Section 2.12, "How to run Discoverer Viewer over HTTP".

• To run Discoverer Plus over HTTPS, you install the Web server's security certificate into the Java Virtual Machine (JVM) certificate store in all client machines that will run Discoverer Plus. For more information, see Section 2.8.1, "How to install a security certificate on a Discoverer Plus client machine".

Notes

• When you install OracleAS, SSL is installed automatically, but it is not enabled by default. To deploy Discoverer using SSL, make sure that SSL is enabled (i.e. make sure that the start-mode parameter in opmn.xml is set to 'ssl-enabled'). For more information, see Oracle HTTP Server Administrator's Guide.

2.8.1 How to install a security certificate on a Discoverer Plus client machine

You install a security certificate on a Discoverer client machine when you run Discoverer Plus for the first time over HTTPS (i.e. in Secure Sockets Layer (SSL) mode).

Hint: If you do not have a JVM installed on the client machine, before you try to run Discoverer for the first time in Secure Sockets Layer (SSL) mode, do one of the following:

• run Discoverer Plus in HTTP mode, which installs a JVM (e.g. Oracle JInitiator) on the client machine for you (for more information, see Section 2.7, "About running Discoverer Plus over HTTP for the first time on a client machine"

• install a JVM on the client machine manually

To install a Discoverer Plus security certificate:

1. Start a Web browser and enter the Discoverer Plus HTTPS URL containing the fully qualified host name (including port number if necessary) used by your own OracleAS installation.

   For example:

   https://<host.domain>:<port>/discoverer/plus

   where:

   • <host.domain> is the server name and domain on which the Oracle HTTP Server is installed

   • <port> is the HTTPS port number (default 4443) on which Discoverer is installed

   • /discoverer/plus is the URL command that starts Discoverer Plus

   The Security Alert dialog is displayed.

    Text description of the illustration connect2.gif

    Note: Notice the padlock symbol displayed on the status bar of the browser, which indicates that the Web session is secure.

    Notes

    • For information about installing security certificates with a JVM other than Oracle JInitiator and Java Plug-in 1.4, consult the JVM's proprietary documentation.

    • If you install a new JVM when you start Discoverer Plus, you must reinstall the Web server's security certificate into the JVM certificate store on all client machines that run Discoverer Plus.

2.8.2 How to import certificate details into the JInitiator certificate store

When configuring Discoverer Plus to run over HTTPS using JInitiator, you import the certificate details into the JInitiator certificate store after you have used the Certificate Export Wizard to export a certificate file (for more information, see Section 2.8.1, "How to install a security certificate on a Discoverer Plus client machine").

To import certificate details into the JInitiator certificate store:

1. Open the certificate file that you saved in Section 2.8.1, "How to install a security certificate on a Discoverer Plus client machine" in a text editor (e.g. c:\tmp\mycertificate.cer).

   The screenshot below shows a certificate file called mycertificate.cer opened in a text editor.

   
   
   Text description of the illustration ssl8.gif

JInitiator's certificate store is contained in a file called certdb.txt

2. Open the certdb.txt file in a separate text editor (for more information about the location of configuration files, see Section A.2, "List of Discoverer file locations").

3. Copy the entire contents (including the '-----BEGIN CERTIFICATE-----' and '-----END CERTIFICATE-----' text) of the certificate file (e.g. c:\tmp\mycertificate.cer) to the end of the certdb.txt file.

4. Save the certdb.txt file.

2.8.3 How to import certificate details into the Java Plug-in 1.4 certificate store

When configuring Discoverer Plus to run over HTTPS using Java Plug-in 1.4, you import the certificate details into the Java Plug-in 1.4 certificate store after you have used the Certificate Export Wizard to export a certificate file.

1. Display the Java Plug-In Control Panel.

   For example, on Windows choose Start | Settings | Control Panel to display the Windows Control Panel, then select the Java Plugin icon.
