This procedure requires you to stop the AS Java. Plan for the required downtime while the AS Java restarts.
When you edit the user management engine (UME) data source configuration file, download the file to a local directory, edit it, and when uploading the edited file, create a new node in the configuration tree for it. In this way you do not lose the original version of the file.
Upgrades may include changes to the data source configuration files shipped with SAP NetWeaver Application Server (AS) Java. When you perform an upgrade of your AS Java, the upgrade does not affect your modified configuration file. You must add these changes to your modified file manually.
If the AS Java is running, you access the data source configuration files online.
