New Features in WebSphere Application Server version 8.0.0.2

WAS 8002 was available for general availability on 1/16/2012. The blog post below provides the necessary links for download and an overview and brief detail of the new features in WebSphere Application Server version 8.0.0.2. Please note that a fix pack contains both features and APAR fixes.

Improvements in WAS 8002  =>

Education on ALL these new features is provided by the IBM Education Assistant here

Customized access logging for WAS 
Before V8.0.0.2 the access log only offered two options for format, common and combined. With  the new access log enhancements added in V8.0.0.2 you can customize how much information, and what information, is displayed. 17 directives were added to display different pieces of information in the access log. These directives, allow for any order the user wants and each directive can be quoted. These access log enhancements provide greater customization and more information on display to the user.

Example:
%h %u %t "%r" %s %b "%{Referer}i" "%{User-agent}i" "%C"
Remote host, URL path not including query string, start time of request (NCSA format), method, path, query-string, and protocol, ..... 

- Directives must be separated by spaces
- Individual directives can be surrounded by quotes
- Directives can be ordered however the user wishes
- Unless noted, all directives will print - if no value is found

Tools from the Virtual Member Manager to clear adapter cache, manage realm default parent & retrieve the data model
  • The Clear Adapter Cache feature is needed to ensure that VMM always returns correct data.  Changes made to the existing Get and Search commands. New control added to be used with the existing Get and Search API. Two new commands added for handling the cache of the adapters. 
  • New commands for set, update, delete, list of realm level default parent. Simplifies configuration and management. Commands can be used in server and local mode
  • VMM data Model is a description of the organization of data in a manner that reflects the information structure supported by VMM. VMM allows to retrieve the different kinds of information related to its data model schema. To retrieve the VMM schema there is currently a supported API. There is no command used from the command line to retrieve the schema.This feature adds new commands to retrieve the different VMM data model that can be used in server and local mode.

Fixing the Performance problem with the Service Data Object (SDO) Repository
The feature focuses on enhancing the performance of the SDO repository. This is done by
changing the way in which the data is accessed by the entity beans. Finder methods fetches the entire objects even if you are interested in just one column in the table, these are exposed to the clients. Replacing the finder methods with the ejbSelect methods and exposing them to client interface enhances the performance by several factors.

sibDDLGenerator enhancements for SIBus - 
Before these enhancements, the sibDDLGenerator command created the CREATE DATABASE statement DDL and created the tablespaces listed here. If the same database had to be shared by multiple messaging engines, it was necessary  to make some changes to the DDLs generated by the sibDDLGenerator command:
remove the CREATE DATABASE statement DDL, and modify the tablespace names. As part of the enhancements to the sibDDLGenerator, two new parameters (-createdbstmt, -tablespaceprefix) are added.  These parameters remove the need for changes to the DDLs generated by the sibDDLGenerator command .

Clarification of fix pack delivery mechanism (PTFs) to ensure fixed service footprint and Support for Installation Manager console mode
