SAP NWA: Net Weaver Administration Tool
SAP ERP NWA Tool
SAP NetWeaver Administrator
Use SAP NetWeaver Administrator is a Web-based tool for administration and monitoring that offers a single entry point to configure, administer, and monitor your SAP NetWeaver system, its components, and the applications running on top of it.
Prerequisites The Application Server Java (AS Java) is running.
Features The SAP NetWeaver Administrator unifies the most important administration, monitoring, and troubleshooting tools. Some of the main SAP NetWeaver Administrator features are:
● A single, central tool for administration, troubleshooting, and problem analysis of your SAP NetWeaver system. You can perform administration tasks, such as starting and stopping instances, checking and modifying configuration settings, analyzing logs and traces, ensuring the error-free functioning of all system components by continuous system monitoring.
● An easy-to-use, task-oriented interface.
● A Web-based tool. Therefore, you do not need to have a local installation to manage remote systems.
● The interface allows seamless navigation to other SAP NetWeaver administration tools (for example, User Management Engine).
● The SAP NetWeaver Administrator represents the crossover from various expert tools to an integrated, simple, and clear solution. The SAP NetWeaver Administrator also completes the integration of the data sources for monitoring.
Activities
Starting the SAP NetWeaver Administrator To start the SAP NetWeaver Administrator, enter the following data in a Web browser: http://<host>:<port>/nwa, where:
● <host> is the host where the AS Java is installed.
● <port> is the HTTP port of the ICM. It consists of 5<Java_instance_number>00. For example, if the instance number of the Java instance is 60 , the HTTP port is 56000 .
Defining the SAP NetWeaver Administrator Security Roles For authorization, the SAP NetWeaver Administrator uses the User Management Engine (UME) and the Java Management Extension™ (JMX) security features. The following security roles are defined from an authorization point of view:
● NWA_READONLY
● NWA_SUPERADMIN The roles include the permissions that enable/disable certain elements in the UI, as well as permissions to access the data in the managed system. The readonly role does not allow making any changes in the managed system such as starting/stopping, changing the configuration and so on, whereas the other role allows full control. Users and roles are mapped by using the Identity Management functions of the SAP NetWeaver Administrator. More information: Identity Management of the Application Server Java
Using the SAP NetWeaver Administrator The management functions included in the SAP NetWeaver Administrator are grouped into work centers according to the type of functionality that they provide. The work centers are sub-divided into work sets grouping related administration options. The number of work sets and their content is dynamic and changes according to the installation scenario. To access the relevant function, choose <work center> → <work set> → <function> , or access the relevant quick link. To display the list with the available SAP NetWeaver Administrator quick links, in your Web browser enter: http://<host>:<port>/nwa/quicklinks, where:
● <host> is the host where the AS Java is installed.
● <port> is the HTTP port of the ICM. The following work centers are available:
● Operation Management
● Configuration Management
● Availability and Performance Management
● Problem Management
● SOA Management
