WebCenter State and Configuration Persistence

Introduction to Oracle WebCenter Administration 1-11 WebCenter Analytics WebCenter Analytics is stateless. Requests received by Analytics Collectors are executed immediately. Any in-transit state, such as a request initiated by a WebCenter application or a request processed by the Analytics Collector, is not guaranteed. WebCenter Activity Graph WebCenter Activity Graph consists of two components: ■ Activity Graph service - does not maintain any in-memory state. The Activity Grpah task flows query the Activity Graph database and display results as a list of recommendations. State is updated by the following: ■ Task flow configuration parameters ■ Personalization settings ■ Not-interested feature The first two are built on the standard Oracle ComposerOracle ADFMDS framework, which manages the state. The last is a feature where the user can indicate that they are not interested in a particular recommendation. This input is persisted synchronously in the database. ■ Activity Graph Engine - runs a batch data analysis process that updates tables in the database transactionally. Although the engine does not support clustering or failover, it can recover from failure. Administrators use the Activity Graph Scheduler to set up and monitor the nightly schedule. The results of the analysis the recommendations are presented through the Activity Graph task flows. The Activity Graph Engine is a singleton application that has a background thread that wakes up periodically to check if it is time to run the nightly job, which can last several hours. The schedule is persisted in the database. If the managed server fails, the job continues when the managed server next starts up. WebCenter Personalization Server WebCenter Personalization Server is a stateless RESTful application. All state is managed in the client requests.

1.3.7 WebCenter Log File Locations

Operations performed by WebCenter applications, portlet producers, discussion servers, and so on, are logged directly to the WebLogic managed server where the application is running: base_domainserversWC_ServerlogsWC_Server.log For example, WebCenter Spaces diagnostics are logged to: base_domainserversWC_SpaceslogsWC_Spaces-diagnostic.log You can view the log files for each WebLogic managed server from the Oracle WebLogic Server Administration Console. To view the logs, access the Oracle WebLogic Server Administration Console http:admin_server_host:portconsole, and click Diagnostics-Log Files . You can also view and configure diagnostic logs through Fusion Middleware Control, see Section 36.3, Viewing and Configuring Log Information. 1-12 Oracle Fusion Middleware Administrators Guide for Oracle WebCenter

1.4 Oracle WebCenter Spaces

1.5 WebCenter Portal Applications

You can develop WebCenter Portal applications using JDeveloper and deploy them to a custom WebLogic Managed Server. For information about developing WebCenter Portal applications, see the Oracle Fusion Middleware Developers Guide for Oracle WebCenter.
