14.1.5 Common Component Log File Information

Cluster wide log consolidation is not offered for Oracle Web Cache, Oracle HTTP Server, OPMN, and WebLogic Managed Servers. For information about the status of an Oracle HTTP Server application, refer to the log files on each Oracle HTTP Server node. To For information about the status of an failed application, refer to the log files on each Server node.

14.2 Oracle Portal and High Availability Concepts

This section describes single-instance information, as well as high availability concepts specific to Oracle Portal. This section guides you through the concepts and considerations necessary for creating a successful high availability Oracle Portal deployment.

14.2.1 Oracle Portal Single-Instance Characteristics

For information about the single-instance architecture of Oracle Portal, see the following sections in the Oracle Fusion Middleware Administrators Guide for Oracle Portal. ■ Understanding the Oracle Portal Components - this section introduces the components of the Oracle Fusion Middleware. It describes how these components work with Oracle Portal. ■ Understanding the Oracle Portal Architecture - this section describes the Portal architecture. Read the following topics in this section: – How Does Oracle Portal Integrate with Other Components? – How Are Pages Assembled in Oracle Portal? – How Does Communication Flow in Oracle Portal? ■ Understanding Caching in Oracle Portal - this section describes the caching configurations you can implement to increase the availability and scalability of medium to large deployments. ■ Understanding WSRP and JPS - this section provides an introduction to the Web Services for Remote Portlets WSRP specifications and Java Portlet Specification JPS. These two standards enable the development of portlets that interoperate with different Portal products, thereby increasing the availability of portlets within an organization.

14.2.1.1 Oracle Portal Request Flow

For information about request flow in Oracle Portal, see the following sections in the Oracle Fusion Middleware Administrator’s Guide for Portal Guide: ■ How Are Pages Assembled in Oracle Portal? ■ How Does Communication Flow in Oracle Portal?

14.2.1.2 Oracle Portal Component Characteristics

The following lists the characteristics of Oracle Portal components: ■ Oracle Portal application runs inside a WebLogic container WLS_PORTAL. Configuring High Availability for Oracle Portal, Forms, Reports, and Discoverer 14-7 ■ Oracle Portal repository stores metadata, documents, customizations, and personalizations. ■ Oracle Portal has a strong dependency on Oracle Web Cache to process and cache content. ■ Oracle Portal depends on Oracle HTTP server to route traffic to WebLogic Server, service product images, and rewrite URLs.

14.2.1.3 Oracle Portal Startup and Shutdown of Processes and Lifecycle

Oracle Portal does not have any process of its own. It relies on standard Oracle tools and utilities to manage Oracle Web Cache, Oracle HTTP Server, WebLogic Managed Server WLS_PORTAL, and the database. The following lists the configuration and monitoring interfaces for Oracle Portal components: ■ Enterprise Manager for managing Oracle Web Cache, Oracle HTTP Server, Oracle Portal, and WLS_PORTAL ■ Oracle WebLogic Administration Console for managing WLS_PORTAL ■ Oracle WebLogic Scripting Tool WLST for adding or editing Portal-specific configuration parameters ■ The opmnctl command line interface for managing Oracle Web Cache and Oracle HTTP Server

14.2.1.4 Oracle Portal Deployment Artifacts
