  • [IBM i]Maximum Performance with WebSphere Application Server V5.1 on iSeries
    Best practice Best practice:

    This book explains how to tune the iSeries server for IBM WebSphere Application Server. The book is divided into several logical tuning tasks, such as tuning the Java virtual machine. You can study each of these logical blocks and apply them independently from other tasks. But, to achieve optimum performance on the system, you should use the systematic approach that is shown in this book.
