9.7 Applying revision patches and installing revised versions

You can install and apply revision patches and revised versions when revision patches are released for Application Server, or when the system undergoes regular maintenance. To apply a revision patch or install a revised version, stop instances of Application Server and the domain administration server (DAS) that are running, and then install the patch or revised version by using the provided media of the product.

Prerequisites

Application Server is running.
The domain administration server (DAS) is running.

Intended users
