Product updates are installed using the IBM Update Installer for WebSphere Software tool. Since new updates are made to the Update Installer tool over time, it may be required to download the latest version of the Update Installer.
The Update Installer is a JAVA application and will run on multiple platforms. For each fix pack, IBM will recommend the appropriate version of the Update Installer.
Just like the WAS installer covered in Chapter 2,InstallingWebSphereApplicationServer, the Update Installer wizard runs either as a graphical user interface or in silent mode with a response file.
The Update Installer is used to apply Fix packs for WAS, IBM HTTP Server (IHS) and also the WebSphere Plug-in.
