Using the post-installer after updating or rolling back to a different service level

For z/OS systems, service that is applied to WebSphere Application Server occasionally requires corresponding changes to be made to the configuration file systems for existing application serving environments that were configured at a lower service level. For distributed operating systems, service that is applied to WebSphere Application Server occasionally requires corresponding changes to be made to the profile directory for existing application-serving environments that were created at a lower service level.

About this task

Most of these post-maintenance or post-installation updates can be performed automatically. This is done by the post-installer.

The WebSphere® Application Server post-installer is a set of scripts that can be used to:
  • Run configuration actions by Installation Manager at installation or uninstallation time
  • Automatically detect the application or removal of fixpacks, and run any necessary configuration actions
  • Automatically detect the addition or removal of an offering, optional feature, or iFix; and then create or remove any associated symlinks
The post-installation process is performed at the node level and must run against each node's WebSphere Application Server home directory after maintenance is applied to the product datasets and HFS and before the node is started. For more information about the post-installer and how to use it to apply or back out service to the configuration HFS, see Completing post-installation tasks after updating or rolling back to a different service level.
