Configuration Steps for SAP NetWeaver Administrator (NWA)

As of SAP NetWeaver 04 SP Stack 12, the SAP NetWeaver Administrator (NWA) is also available to you for landscape-wide administration and central monitoring.

The NWA runs as an application on the J2EE Engine and is called using the URL :
http://host:port/nwa

To use the NWA for central monitoring, install a Java Add-In for your CEN, if it does not already have one. Since you can use the NWA not only for central monitoring, but also for central administration, the corresponding double-stack system is referred to as the central administration and monitoring system. This system is also abbreviated to CEN

If you want to use the NWA to monitor your system landscape, you need a System Landscape Directory (SLD), since information about the monitored systems is stored in the SLD for this application. We recommend that you set up an SLD on the J2EE Engine of CEN for this purpose. This SLD is known as the administrative SLD.

• You need to configure and start the administrative SLD; you also need to enter all ABAP and Java systems in your system landscape into this SLD.
• CEN must be able to write data about the agents of the monitored systems to the administrative SLD. You need to create special connections and authorizations for this.
• You also need to set up a special RFC connection between the ABAP and the Java stacks of CEN.
• If you want to use the NWA to administer multiple Java systems, we recommend that you store the corresponding logon data in the NWA's J2EE Engine, so that you do not need to log on with a user name and password every time.

To simplify this step, the Template Installer is available in the NWA. You can use it to perform the above configuration steps more easily.
