Installing maintenance packages overview

Before you install maintenance to your WebSphere® product, you should be familiar with the following important considerations and precautions.

Note: If you previously imported WebSphere Application Server Version 7.0 into Installation Manager, you cannot use Installation Manager to update it. You must use the instructions given in this section and use the Update Installer to install any fixes. After you use the Update Installer to apply maintenance to the base WebSphere Application Server product or the IBM SDK, you must reimport the WebSphere Application Server Version 7.0 installation into Installation Manager.

Overview of the installation procedure

The Update Installer wizard is an InstallShield for Multiplatforms wizard that runs in silent mode with a response file.

  1. Ensure that the Update Installer for WebSphere Software is installed on your system. The Update installer can be installed from the WebSphere for IBM® i supplements disk, which is included with the installation media. Additionally, when you apply the latest WebSphere Application Server for IBM i group PTF, the current level of the Update Installer is installed if it is not already installed on the system. The default install location for the Update Installer is /QIBM/ProdData/WebSphere/UpdateInstaller/V7/UPDI. For more information, see the documentation on installing the Update Installer.
  2. Download the most current version of the interim fix, fix pack, or refresh pack file from the Support site into the updi_root /maintenance directory.
    Note:
    • The WebSphere Application Server for IBM i group PTF always includes the most recent fix pack or refresh pack for the product. If you have applied the group PTF, there is no need to download the current fix or refresh pack level.
    • If you have not installed features, such as language packs and samples, consider installing the features if there is a chance you might use them in the future. If you choose not to install the features and then later install maintenance, you will have to uninstall all maintenance, install the features, and then reapply all maintenance or the features might be corrupted.
  3. Use the Update Installer to install the interim fix, fix pack, or refresh pack.
    The Update Installer creates a backup file in the app_server_root/properties/version/nif/backup directory.
    Note:
    • The WebSphere Application Server group PTF includes the most current fix or refresh pack for the product along with required PTFs for other products that Websphere relies on. For more information refer to Installing the WebSphere Application Server group PTF on IBM i.
    • The group PTFs do not contain any feature pack related items. You can download these items from the support site.

Permissions

Permissions can only be given to one user account. To install and launch the Update Installer, use the same user account that installed WebSphere Application Server, or give permission to another user. If permission is given to a non-root user, then the non-root user should give permission to the root user when finished installing maintenance. If the non-root user does not return permission to the root user, then the root user cannot read or write to the file system.

Updating existing profiles in WebSphere Application Server products

The Update Installer updates the core product files in a WebSphere Application Server product. Service in a maintenance package might update the following files in the installation root directory:
  • JAR files in the lib directory
  • Scripts in the bin directory
  • Profile templates

Updating cluster members

Apply the same maintenance packages to all of the WebSphere Application Server installations in a cluster. When all of the cluster members are not at the same service level, the following exception can occur:
DRSCacheApp   E DRSW0008E: 
   Exception is: com.ibm.disthub.impl.jms.JMSWrappedException: 
   {-1361012295|unknown|java.io.OptionalDataException|} 

This error can cause memory replication to function improperly.
