Activating the Emergency User

Prerequisites

The AS Java must be able to access the database of the AS Java.

Context

In emergency situations, you can activate the emergency user SAP* to enable you to log on to applications, in particular the configuration tools, and change the configuration. Such situations include the following:

• You configured user management incorrectly and can no longer log on to any applications
• You configured the data source incorrectly and the SAP NetWeaver Application Server (AS) does not start
• All administrator users are locked

The SAP* user has full administrator authorizations. For security reasons, the SAP* user does not have a default password, so you must specify a password when you activate the user.

NOTE:  Once you have activated the SAP* user, no other user can log in to the system.

Procedure

1. Activate the SAP* user:
   1. Start the config tool for editing user management engine (UME) properties as described in Editing UME Properties .
   2. Set the following properties:

      Property	Value	Comment
      ume.superadmin.activated	true	This activates the SAP* user.
      ume.superadmin.password	<password>	Enter any password of your choice. This defines the password for theSAP* user.

   3. Restart the AS Java.
   The SAP* user is now activated. While it is activated, all other users are deactivated. You can only log on with the SAP* user.
2. Fix your configuration as required, logging on with the user ID SAP* and the password you specified.
3. When you have fixed your configuration, deactivate the SAP* user again.
   1. Start the config tool for editing UME properties.
   2. Set the property ume.superadmin.activated to false.
   3. Restart the AS Java.
