This IBM Redbooks publication describes how to run the IBM Java Virtual Machine for AIX and WebSphere Application Server V6.1 on IBM System p and the AIX 5L Operating Systems. In terms of provisioning, tuning and maintenance, it consolidates information from all of these areas into a single resource and explains how you can implement, tune, and utilize the unique features of the IBM POWER Systems platform, AIX, and WebSphere Application Server together for maximum optimization. The book is intended for UNIX system administrators, Java developers, infrastructure designers, J2EE architects, project managers, performance testers and anyone who runs WebSphere Application Server on System p and AIX. It may contain some information which you already know, and other information that is new to you, depending on your background. AIX system administrators may be expert in configuring logical partitions and advanced virtualization, but may gain an understanding from this book about how WebSphere deployment teams may be able to exploit the features of IBM POWER Systems and AIX. WebSphere infrastructure architects may already know exactly how they want their redundant systems to work, but might learn how AIX teams can provide two or three physical servers that provide all of the different levels of application services necessary for the entire application lifecycle environment.
