services, libraries, and interfaces working on each element in a

single GUI

Includes functions for:

Obtaining general information about a service, manager, interface, or

library

Logging on to the SAP J2EE Engine via the Visual Administrator tool

Administrating and changing the properties either specific or common

for each service or manager

SAP NetWeaver Administrator (NWA) is the new central

administration and monitoring tool for the 6.40 and above Java

systems of your SAP NetWeaver system landscape

SAP NetWeaver Administrator is a Java application that ships with

SAP NetWeaver 6.40 SP 12 and SAP NetWeaver 7.0

SAP System forCentral Monitoring

CEN

Central Monitoring permits monitoring a number of

systems from one central system. The system used for

Central Monitoring is referred to as CEN.

Steps to Set Up CEN System - Java

Activate background and Central System Dispatching

Create the CSMREG user

Create the CSMCONF Start File for CCMS agents

Register the CCMS Agent SAPCCMSR in Visual Administrator

Check Java instance in RZ21 Topology

Enter Java instance in ST03G

51

CEN Setup – Entering Java Systems in ST03G

Start the Global Workload Monitor in CEN by calling transaction

ST03G

In the navigation bar, expand the Settings & Log subtree, and

double-click the System Selection entry

Add an additional row to the desired list of monitored components by

choosing the (Append Row) button

52

CEN Setup – Entering Java Systems in ST03G (cont.)

Check activated and enter the following data in this row:

Component Name under which the monitored system is displayed; use

the following naming convention:

J2EE Engine:<Engine-Host>_<SysID>_<Engine-ID>

Java Database Interface: <Engine-Host>_<Engine-SysID>_<Engine-

ID>_JDBI

Comp. Type SAPJ2ENode or SAPJDBI

Mon. Sys. System ID of the primary system with which the agent is

registered

Mon. Sys. Dest. RFC destination of the system ID of the primary agent

system; if a suitable destination does not yet exist, create this using

transaction SM59

NWA Central Configuration

Perform the following steps:

Configure and activate the System Landscape Directory (SLD)

Activate the Object Server

Load the CIM model

Start the Data Supplier Bridge

Adjust the Central Monitoring System (CEN)

For every instance of a J2EE Engine:

Register a CCMS Agent SAPCCMSR

For every ABAP instance:

Register a CCMS Agent SAPCCM4X

Register CCMSPING and assign the monitored systems

Setup NWA connections

59

Connecting CEN to NWA – Template Installer

These templates are designed to connect NWA

to an SLD on the same instance

For monitoring your CEN, SLD and NWA should be on the same

instance

If they are not, you need to do some steps manually

It makes sense for these tools to reside on the Solution Manager

instance

Some systems (NWDI, PI) should have Production Type SLD

Solution Manager is not always considered a Production Machine

Spend time creating an architecture for your monitoring systems

7 Key Points to Take Home

Your monitoring should be consistent and repetitive

Make notes on errors that occur normally in your Java engine with

no apparent ill effects

Configure Central Monitoring at least for plug-ins

Create a monitoring architecture

Carefully plan your SLD architecture

NWA will eventually replace Visual Administrator

Investigate the application monitors in your Java applications
