IBM Connections wiki : Tuning for Performance : IBM Connections 4.0 Performance Tuning Guide

Posted on by CyberDude

This document provides recommendations for performance tuning of IBM Connections 4 Connections based on the experience of the IBM Collaboration Solutions Performance team. However, the optimal tuning and the resulting system capacity can be affected by many factors, including the characteristics of the load on the system and the hardware used, including servers, disk subsystems, network topology, and more. Therefore the recommendations in this document should not be considered the optimal values for every situation, but rather a recommended starting point for tuning a Connections deployment. Using this configuration as a baseline, we suggest monitoring the system performance, making any desired changes, and measuring their impact.

IBM – IBM WebSphere Portal Version 6.0 Tuning Guide

Posted on by CyberDude

Abstract

Tuning a WebSphere Portal environment involves tuning and configuring the various systems and components of the environment. This chapter discusses some general concepts and details the specifics of the configurations used in our measurement environments. These specifics entail:

* configuring the application server and the resources defined for that application server

* determining the cloning strategy for expanding or extending the environment

* tuning the database(s) and database server

* tuning the directory server and its database

* tuning the web server

* tuning the operating system and network

* tuning the WebSphere Portal services

When tuning your individual systems, it is important to begin with a baseline, monitor the performance metrics to determine if any parameters should be changed and, when a change is made, monitor the performance metrics to determine the effectiveness of the change.
