Features

Liberty profile Lightweight applications runtime. Small footprint, low overhead. Single, sharable configuration. For developers
Support for Java 7 Java 6 is installed with the product and used by default. WAS V8.5 provides optional support for the IBM WebSphere SDK Java Technology Edition v7.0. This IBM SDK provides a full-function SDK for Java compliant with Java SE 7 application programming interfaces. To use Java 7, install IBM WebSphere SDK7.0 using IBM Installation Manager and then use the managesdk tool to enable it.

High availability Provides...

  • A framework that allows singleton services to remain highly available
  • A mechanism that allows servers to exchange state data
  • A specialized framework for high speed, reliable messaging between processes

Messaging infrastructure Message resilience is improved in the following areas:

  • Recovery of messaging engine errors in high-availability environments
  • Prevention of long-running database locks
  • Performance of messaging bus at start-up

Memory leak detection and protection Pattern-based memory leak detection, prevention, and response by watching for suspect patterns in application code at run time. Includes:

  • Ability to mitigate a memory leak when stopping applications
  • Ability to prevent leaks, receive warnings and get system dumps
  • Managed beans (MBeans) to list the applications that have memory leaks


Administrative control

Centralized Installation Manager (CIM) Manage version 8.5 and previous versions of WAS. Install or uninstall WAS on remote machines. Perform maintenance from the dmgr console.
Cross Component Trace (XCT) Follow the flow of requests from end-to-end. Requests can be tracked as they traverse thread or process boundaries and travel between stack products and WAS.
Configuration repository checkpoint and audit report Back up copies of files from the master configuration repository. We can use a checkpoint to restore the configuration repository back to a prior state.
High Performance Extensible Logging (HPEL) Store logging information produced by the application server or the applications.
