There are a number of differences among the offered packages of WebSphere Application Server V5.0 for Linux on iSeries. In the following sections we outline the most important of these differences.
This edition addresses the basic programming and execution needs of desktop developers and single-server production scenarios. The execution environment for this edition addresses standards-based programming for Web and component-based programming, as well as Web services. The administration model for this edition presumes a single-server environment: no clustering for failover or workload balancing, nor centralized administration of multiple server instances. However, you can add a stand-alone node to a centrally administered network (the cell) at any time after installing the Network Deployment (ND) edition, which controls the cell.
The following features are included in this edition:
Full J2EE support
IBM HTTP Server
XML and XSL parsers
Integrated Java Message Service (JMS) server
Dynamic network caching
Java Management Extensions (JMX) systems management support
An ANT-based administrative tool called ws_ant
HTTP session state failover support
A session manager integrated into each application server
Web services support, including Web Services Invocation Framework (WSIF), WS-Security, and a technology preview of JSR109
New security features, including support for JAAS, CSIv2 interoperability, Java 2 security, and third-party security providers
Performance Monitoring Infrastructure (PMI) integrated with JMX
Resource Analyzer, which has been rebranded as Tivoli® Performance Viewer and includes extended functionality
Troubleshooting includes First Failure Data Capture (FFDC), which allows you to collect data based on the first failure in the system
The collector script gathers system information and packages it in a JAR file that you can send to IBM Service for analysis
This edition addresses Application Server execution in departmental computing scenarios. It provides centralized administration of multiple server instances, as well as basic clustering and caching support.
This edition supports all the features of the Base Edition plus:
Clustering Distributed Configurations
Support for network authentication and single sign-on
UDDI - Universal Description, Discovery and Identification registry
Webservices gateway (WSGW)
This edition addresses large information technology (IT) production scenarios for applications that are designed according to the core, standards-based programming model of Java 2 Platform, Enterprise Edition (J2EE) and Web services. It supports large-scale clustering, caching, content distribution, and dynamic workload management to help gain efficient utilization of shared resources in the I/T computing center. It also addresses complex programming requirements for integrating applications and lines of business, by introducing super-standard programming functions for business process management, integration adapters, rules management, and message transformations.
This edition supports all the features of the ND edition plus the following features:
Queue Manager Server
Business Rule Beans
Business Policy Management
Application Server extensions as Programing models and deployment manager
