6.3.2 Setting Optional Presentation Services Parameters

You can optionally configure certain parameters that control the communication between Presentation Services and the JavaHost component. To configure Presentation Services, set parameters in the instanceconfig.xml file on each computer that hosts Presentation Services. To configure Presentation Services for clustering: 1. Open the configuration file instanceconfig.xml for editing. You can find instanceconfig.xml at: ORACLE_INSTANCEconfigOracleBIPresentationServicesComponent coreapplication_obipsn 2. Under the ServerInstance tag, the JavaHostProxy element has optional subelements. Table 6–3 describes these optional subelements. 3. Save and close the file. 4. Repeat these steps for every Presentation Services instance in your deployment. 5. Restart Oracle Business Intelligence.

6.3.3 Setting Optional Oracle BI Presentation Services Plug-in Parameters

You can optionally configure the Oracle BI Presentation Services Plug-in to control session redirection behavior. To do this, you must perform the steps in this section on each computer where the analytics Java component is installed. To set optional parameters for the Oracle BI Presentation Services Plug-in: 1. Open the bridgeconfig.properties file for editing. You can find this file at: MW_HOMEuser_projectsdomainsdomain_nameconfigfmwconfig biinstancescoreapplication

2. Optionally, you can include the parameter AlwaysKeepSessionAffiliation to

control whether requests that belong to the same session can be redirected to another Presentation Services component if the current Presentation Services component score is too low. Table 6–3 Optional Subelements for the JavaHostProxy Element Subelement Attribute Description LoadBalancerPing keepAliveMaxFailures Specifies the number of ping failures required before the host is declared nonfunctioning. The default value is 5. LoadBalancerPing keepAliveFrequencySecs Specifies the ping frequency in seconds. The default value is 20.
