4.5.6 Using the Update Installer

A few tips for using the Update Installer: - It is important that you unzip or untar the update software into the <install_root> directory of the appropriate product. This unpacks the downloaded package automatically into the <install_root>/updateinstaller directory, which contains the Update Installer, and several subdirectories including the maintenance directory which contains the maintenance package itself. See Figure 4-6.

Figure 4-6 Subdirectories of the update installer directory - It is very important that no WebSphere related processes are active on the system during the update or the installation fails. This includes not only the appserver processes, Node Agent and Deployment Manager processes, but also the InstallShield and Profile creation wizard, the IBM Rational® Agent Controller process, or Application Client processes, and so on.

If your update fails, you first need to uninstall the failed update package, then start the update again.
