Activate Emergency User on SAP AS Java

 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:

a.    Start the config tool for editing user management engine (UME) properties as described in Editing UME Properties .

b.    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 the SAP* user.

c.    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.

a.    Start the config tool for editing UME properties.

b.    Set the property ume.superadmin.activated to false.

c.    Restart the AS Java.

4.   Refer SAP Note 669848 for more details.

 BUT

7.   Sometimes the button "Set Custom Value" in ConfigTool is disable and you can't apply the values.

8.   In this case please read note 1596787 - Error activating emergency user on 7.1 J2EE AS
