1 Introduction and Roadmap

This chapter describes the contents and organization of this guide—Administering WebLogic Server for Oracle Exalogic Elastic Cloud.

This chapter includes the following sections:

• Document Scope and Audience

• Guide to this Document

• Related Documentation

• Samples and Tutorials

• New and Changed Features in This Release

Note:

The WebLogic Replicated Store, which is intended only for use in Oracle Exalogic Elastic Cloud environments, is deprecated as of Oracle WebLogic Server version 12.2.1.3.0 and will be removed from WebLogic Server in a future release. WebLogic Server components that enable the configuration and management of the WebLogic Replicated Store, such as the DomainMBean.ReplicatedStores attribute, the weblogic.management.configuration.ReplicatedStoreMBean API, and this document, are also deprecated and will be removed. As of Oracle WebLogic Server 12.2.1.3.0, Oracle recommends that you use either a JDBC store or a custom file store for JMS message storage.

Document Scope and Audience

This document is written for application developers and system administrators who develop and administer applications for WebLogic Server in Exalogic Elastic Cloud Software environments. It is assumed that readers are familiar with the WebLogic Server platform, Java Platform, Enterprise Edition (Java EE) programming, and Exalogic Elastic Cloud Software.

Guide to this Document

• This chapter, Introduction and Roadmap, introduces the organization of this guide.

• The chapter WebLogic Server Domain Optimizations for Exalogic Elastic Cloud Software provides information on how to optimize WebLogic Server domains for Exalogic Elastic Cloud.

• The chapter Using the WebLogic Replicated Store for WebLogic Server Messaging Services explains how to use a WebLogic Replicated Store to provide a scalable and high-performance storage option for WebLogic Server Messaging services that require persistence in Oracle Exalogic Elastic Cloud environments.

• The chapter WebLogic Server Cooperative Memory Management in Oracle Exalogic Elastic Cloud Environments provides information about how to use Cooperative Memory Management to promote effective memory utilization by WebLogic Server resources.

• The chapter Message Compression In Oracle Exalogic Elastic Cloud Environments provides information about how to configure message compression for JMS Store I/O operations which may provide significant performance improvements in Oracle Exalogic environments.

Related Documentation

This document contains specific development and administration information for WebLogic Server in Oracle Exalogic Elastic Cloud environments, see Exalogic Elastic Cloud Software in Licensing Information.

For comprehensive guidelines for developing and managing WebLogic Server applications, see the following documents:

• Introduction to Oracle WebLogic Server in Understanding Oracle WebLogic Server provides an overview of Oracle WebLogic Server features and describes how you can use them to create enterprise ready-solutions.

• Performance Tuning Roadmap in Tuning Performance of Oracle WebLogic Server provides information on how to improve system performance and tune the components in a WebLogic Server environment.

• Understanding JMS Resource Configuration in Administering JMS Resources for Oracle WebLogic Server provides information on how to configure, manage, and monitor WebLogic JMS resources.

• Using the WebLogic Persistent Store in Administering the WebLogic Persistent Store.

• Understanding WebLogic Server Deployment in Deploying Applications to Oracle WebLogic Server is the primary source of information about deploying WebLogic Server applications.

Samples and Tutorials

In addition to this document, Oracle optionally provides a variety of code samples and tutorials for developing applications. The examples and tutorials illustrate WebLogic Server in action, and provide practical instructions on how to perform key application development tasks. You can start the Examples server from the ORACLE_HOME\user_projects\domains\wl_server directory, where ORACLE_HOME is the directory you specified as Oracle Home when you installed Oracle WebLogic Server. For more information, see Sample Applications and Code Examples in Understanding Oracle WebLogic Server.

Avitek Medical Records Application (MedRec) and Tutorials

MedRec is an end-to-end sample Java EE application shipped with WebLogic Server that simulates an independent, centralized medical record management system. The MedRec application provides a framework for patients, doctors, and administrators to manage patient data using a variety of different clients.

MedRec demonstrates WebLogic Server and Java EE features, and highlights Oracle-recommended best practices. MedRec is optionally installed in the WebLogic Server installation. You can start MedRec from the ORACLE_HOME\user_projects\domains\medrec directory, where ORACLE_HOME is the directory you specified as Oracle Home when you installed Oracle WebLogic Server. For more information, see Sample Applications and Code Examples in Understanding Oracle WebLogic Server.

New and Changed Features in This Release

WebLogic Server includes the following new features for Oracle Exalogic Elastic Cloud environments:

• A WebLogic Replicated Store to provide a scalable and high-performance storage option for WebLogic Server Messaging services, see Using the WebLogic Replicated Store for WebLogic Server Messaging Services.

• Cooperative Memory Management to promote effective memory utilization by WebLogic Server resources, see WebLogic Server Cooperative Memory Management in Oracle Exalogic Elastic Cloud Environments.

• An optimization for JDBC stores to commit a batch of INSERT or DELETE operations instead of issuing a separate commit call to the database server, see Enabling JDBC Store Exalogic Optimizations.

• TopLink optimizations that include: batch writing, increasing the default cache size, and enable other optimizations such as weaving eager relationships. See Enabling TopLink Exalogic Optimizations.
