6.6.1 How to specify a centralized Discoverer Preferences component

If you want to store all Discoverer end user preferences in a single location, you configure each Discoverer installation to use the Preferences component running on the Preferences server machine, instead of running their own Preferences component. The diagram below shows how additional Discoverer middle-tier machines reference the preferences on the Preferences server machine. To specify a centralized Discoverer Preferences component, you must perform the following tasks: ■ Choose the machine you want to use as the Discoverer Preferences server machine, and find out the host name and port number of that machine. For more information, see Section 6.6.2, How to find out the host name and port number of the Preferences server machine. ■ Specify the Discoverer Preference server machine for other Discoverer instances to use, and disable the Preferences component on all machines except the Discoverer Preferences server machine. For more information, see Section 6.6.3, How to specify a Discoverer Preferences Server on other machines.

To find out the host name, a. Open a command prompt on the Discoverer Preferences server machine. b. Type hostname and note the value displayed. 2. To find out the port number of the Discoverer Preferences server machine, a. Open the opmn.xml file in a text editor or XML editor. For more information about the location of the opmn.xml file, see Section A.1, Discoverer file locations . b. Locate the PREFERENCE_PORT variable ID and note the value.
