SAP
NetWeaver is a web-based, open integration, application platform that serves as
the foundation for enterprise service-oriented architecture (enterprise SOA)
and allows the integration and alignment of people, information, and business
processes across business and technology boundaries. It allows the composition,
provisioning, and management of SAP and non-SAP applications across a
heterogeneous software environment. See SAP Netweaver training for more details.
Netweaver
runs both Java (and rightfully, J2EE Services) and ABAP independently or in
some cases both ABAP and Java together (e.g. Solution Manager and PI). Netweaver
also has its own release and release strategy. For example NW 7.0 or NW 7.0
EHP1 or NW 7.3.
Application center and instances
The
SAP NetWeaver work center includes the configuration of the following tools:
Adobe
Document Services − This allows you to register the Adobe Reader Rights
credentials as well as keep track of all unlicensed interactive form designs in
your system.
Application
Module − This allows you to view the details of the deployed applications
and their modules. Here, you can also perform the run-time configuration of the
application modules.
Application
Resources − This allows you to enable applications to make use of external
resources. A NW Administrator can add or delete the application resources.
Authentication
and Single Sign-On − This allows you to choose the required authentication
mechanism for your applications. You can configure the following authentication
and SSO:
- AS Java as service provider
- Kerberos
Certificates
and Keys − This allows you to manage the AS Java certificates and keys.
Composite
Application Framework Authorization Tool − This allows you to manage
business rules and Instance Level Permissions for CAF applications, business
object nodes and AS Java instances.
Configuration
Wizard − You can make technical settings required for the technical
processing of a system or a technical scenario.
Destinations
− This can be used to specify the remote service's address and the user
authentication information for remote connections.
Development
Infrastructur − This is required while developing with Java and you want to
manage it with Transport Management System (TMS).
Identity
Management − This allows you as an administrator to control applications
access by creating users and providing these users with a means of
authenticating themselves to an application.
Internationalization
− This allows you to manage data from double stack systems and also used for
synchronization purpose.
Java
HTTP Provider Configuration − You can create new virtual hosts and
configure existing ones for all registered systems.
Java
Class Loader Viewer − You can monitor the hierarchy and references between
the class loaders in the AS Java.
Java
System Properties − Using this, you can view current system configuration
of Application server JAVA and you can edit the properties that are marked as
online modifiable.
Java
Connection JCo RFC Provider − You can manage the Java Connector Remote
Function Call (JCo RFC) Destinations. This allows you to create, edit and view
existing connections.
JMS
Server Configuration − This is used to create new JMS resources.
Licenses
− You can request and install new SAP licenses.
Log
Configuration − You can view current log configuration, change security or
reset it to default.
Message Server − You can monitor message server
parameters and settings.
SAP NetWeaver Administrator Tool − SAP NetWeaver
Administrator (NWA) is a web-based tool that allows you to perform
configuration, advanced administration, and also to monitor, troubleshoot, and
diagnose a SAP NetWeaver system.
You can use NWA tool in the following working modes:
- Online
- Local and remote
Managing Java

Step 4 − Select an instance to perform the following
functions under NWA
- Start, stop or restart a Java instance.
- Enable or disable debug mode for AS Java processes.
- View and refresh OS processes.
- Clear the DNS cache for a particular instance.
- Set a number of server processes (nodes).
SAP NW system landscape
Follow
these steps to perform the implementation of SAP NetWeaver system:
Step
1 − Plan the implementation by defining the scope, hardware and software
requirements, and release instructions.
Step
2 − Define the system landscape for the use cases.
Step
3 − Install the components of SAP NetWeaver system.
Step
4 − Configure SAP NW systems.
System Landscape Management Using SAP
Solution Manager
SAP
recommends the use of the latest version of the SAP Solution Manager to manage
your system landscape. See SAP solution manager training to learn how to manage system landscape. It is important
to correctly define your SAP system landscape in the following versions of SAP
Solution Manager to maintain it correctly.
SAP solution manager 7.0
You
can use the SAP Solution Manager System Landscape transaction code — SMSY for
the complete system description.
SAP Solution Manager 7.1 SP01 to SP04
You
can use the Landscape Management Database transaction code — LMDB to maintain
technical system information. To maintain logical product information, you can
use the transaction code — SMSY.
Verifying Landscape with SAP solution
manager
To
verify and correct your system landscape, SAP recommends that you use the
verification functions of the following versions of SAP Solution Manager.
SAP solution manager 7.0 to 7.1 SP04
Use
Landscape Verification 1.0 for SAP Solution Manager. This add-on allows you to
identify and correct issues in your SAP Solution Manager landscape (Transaction
SMSY) before they cause problems, for example, during a system update. Example
for errors are a missing connection to the System Landscape Directory or the
incorrect assignment of products to technical systems. For each type of error,
a generic description for the solution is provided.
SAP solution manager 7.1 SP05 or higher
Use
the landscape verification function that is embedded into the product system
editor of the Landscape Management Database (LMDB). It replaces the previous
Landscape Verification tool.
