SAP
License Keys 
You need a license key to use the following NetWeaver components:
· SAP Web Application Server
· SAP Enterprise Portal
After you have installed the components the system is equipped with a temporary license, which is valid for four weeks. During this time you have to apply for a permanent license from SAP and install it.
For information about how to apply for a license key from SAP go to the SAP Service Marketplace and look under alias /licensekey.
http://service.sap.com/licensekey
How you import the license key into your system depends on the component for which the license is valid for.
·
You can find
information about installing, testing, and deleting SAP licenses in
SAP License
(BC-CST-SL). This documentation is valid for both ABAP-only and ABAP+Java
installations of the SAP Web Application Server.
· The procedure for Java-only installations is described in Licensing the SAP J2EE Engine.
You can find information about using the license key for the portal in Licensing the Portal and also in the SAP Service Marketplace under the alias /licensekey.

The portal can be started on the Java-only installation of the Web AS or on the ABAP+Java installation. Apply for the appropriate Web AS license, as described above.
In a high
availability environment you also have to apply for the hardware key of the
host that replaces the message server if this fails. For more information see
High Availability
Configurations.
