Component documentation Wizard-Based Configuration of the SAP NetWeaver Administrator  Locate the document in its SAP Library structure

Purpose

The SAP NetWeaver Administrator (NWA) is available to you for administration and monitoring. It runs as an application on AS Java and exists in two versions:

·        Local NWA

As a local NWA, it monitors and administers its own local system. No additional configuration is required to do this. You can call the local NWA with the URL http://<host>:<port>/nwa.

·        NWA for landscape-wide monitoring and administration

You use this NWA for landscape-wide monitoring and administration. The corresponding system is called CEN. You need to perform various configuration steps both in CEN and in the monitored systems to do this. These are presented here. The NWA for landscape-wide monitoring and administration requires a double-stack system (ABAP + Java) with the additional Usage Type EP.

You can call the NWA with the URL http://<host>:<port>/irj/nwapi.

This process describes the configuration of a NWA for landscape-wide monitoring and administration using the Configuration Wizard. There are two configuration tasks with which you can set up central monitoring:

·        Configure NWA

In this task, you perform the configuration steps to set up the NWA for landscape-wide monitoring and administration on a double-stack system. The necessary steps to configure central monitoring are performed as part of this.

·        NWA Add Managed System

In this task, you perform the necessary configuration steps to monitor a remote system with the NWA for landscape-wide monitoring and administration. Perform this task in the central system for each monitored logical system. You can only perform this task once you have performed the task Configure NWA in the central system.

Background documentation

One of the steps that you perform in these tasks is to create or maintain an administration landscape. This term is explained briefly here.

An administration landscape is a group of systems that are monitored by exactly one central system. A system can also only belong to one administration landscape.

§         When you execute the task Configure NWA, the system is assigned as the central system of an administration landscape (which is created with the corresponding choice in the task). This assignment, and possibly creation, is performed in the SLD to which the central system is connected.

§         When you execute the task NWA Add Managed System, the monitored system is added to the administration landscape to which the central system belongs.

·        The two configuration tasks above include the configuration of availability monitoring of Java-based applications with GRMG (se Configuring GRMG for Java-Based Components).

However, this step is also available to you as a separate configuration task, Standalone Setup for GRMG. Perform this task if you want to perform the relevant configuration step more than once for each monitored system. This is especially the case if you want to activate more than one, but not all available GRMG scenarios.

Example

You want to activate only the GRMG scenarios for AS Java and the Enterprise Portal for a monitored system. You register this system with the NWA for landscape-wide monitoring and administration as usual with the task NWA Add Managed System. In the context of this task, you select the J2EE entry in the Available Scenarios dropdown list.

·        The configuration task Configure NWA includes the configuration of the DB Admin Cockpit (see Configuring the DB Admin Cockpit).

However, this step is also available as a separate configuration task, NWA Add Managed System to CENTRAL for DBACockpit monitoring. Perform this task is you want to administer more than one database centrally.

Integration

To be able to perform the above configuration tasks, the following prerequisites must be fulfilled:

·        Both the central system and all monitored systems are already in the SLD with which CEN is registered (see SLD Wizard-Based Configuration).

·        All monitored hosts also need to be registered in the SLD for the Adaptive Computing Infrastructure (see Registering Hosts with the SLD with sldreg)

·        The configuration task NWA Add Managed Systemrequires that the availability agent CCMSPING is registered with CEN. (More information: Installing Availability Agent CCMSPING) The correct sequence is therefore:

                            a.      Task Configure NWA

                            b.      Installation of the availability agent CCMSPING

                            c.      Task NWA Add Managed System

Features

In the context of the NetWeaver Initial Setup (more information: Configuration Wizard), you configure, among other things, the SAP NetWeaver Administrator; this configuration consists of two parts:

·        Configuring the NWA

·        Adding a Monitored System to the NWA
