There are various components of the SAP NetWeaver PI that are not or not fully covered by the central tools. Several tools are available to access these components.
The System Landscape Directory is a central repository of information about software and systems in the data center called the Common Information Model (CIM).
The SLD can be accessed via http://<full qualified hostname>:<HTTP port>/sld.

The Exchange Profile is an XML document that is stored in the main database of the SAP NetWeaver Process Integration. The parameters contained in this document define some basic technical settings. Most of them are initialized automatically during the installation phase, but in some cases the administrator may need to maintain them.
The SAP NetWeaver PI provides a maintenance interface for this file. The maintenance screen for the Exchange Profile can be accessed at:
SAP NetWeaver PI Tools page→ Administration → Repository Tab; Properties Administration→ Exchange Profile.
Settings that are maintained in the Exchange Profile include connection parameters such as hostnames, ports, users, and passwords that allow the various components of the SAP NetWeaver PI to communicate.

The Integration Server is used primarily to process XI messages. The Integration Engine is the runtime engine for XI messages. The Integration Engine processes messages that are rendered in the special XI-SOAP format.
It is important to distinguish between the terms Integration Engine and Integration Server. The Integration Engine running on the central Process Integration system is configured as the Integration Server. The other Integration Engines running on different Application Systems are acting as clients communicating with the Integration Server with XI messages.

Transaction SXMB_ADM is the entry transaction to various configuration and administration possibilities.

Here, the port above refers to the http port of the Internet Communication Manager (ICM) of the AS. To find out the number of this port, go to transaction SMICM and choose Goto→ Services (or press Shift-F1).
With SAP NetWeaver PI 7.1 the ICM takes over the role of the Java Dispatcher know in 6.40 and 7.0. In SAP NetWeaver PI 7.1 only the ICM HTTP port is used to access both stacks.
The query string at the end of the URL would be different for other pipeline entry points. For instance, if a document was sent from the Integration Server to the pipeline on an Application System, the URL would be http://<full qualified hostname>:<HTTP port>/sap/xi/engine?type=receiver.

Configuration objects from the Integration Directory are cached at the Web Application Server for fast access at runtime. The cache can be viewed and managed in transaction SXI_CACHE. A cache refresh (either a delta or a full refresh) can be started inside this transaction.
Connection data for configured Adapter Engines are also cached. To see this information, call transaction SXI_CACHE, choose Goto→ Adapter Engine Cache.
In an productive system a manual intervention of a explicitly started cache refresh should not be necessary. Only in emergency situations a cache refresh might be requested by SAP support.
Figure 31: Transaction SXI_CACHE
Out of the PI configuration tools page (http://<full qualified hostname>:<HTTP port>/dir) the cache status can be checked by selecting Administration and selecting the tab Repository or Directoryand navigating down to Lock and Cache Administration→ Data Cache Overview.
For general administration purposes, further tools are used. There may be tasks such as adding or deleting of additional server processes. The configuration of thread pool sizes and thresholds are examples of advanced administration tasks.

Figure 32: SAP AS Java: Config Tool and Telnet Console
The main tools for these basis administration and configuration tasks on operating system and database level are the Config Tool and the Telnet Console. The Config Tool is a Java application that has to be started locally on the host of the SAP NetWeaver PI system. The Telnet Console is a connection via the telnet protocol accessing the Java Application Server on port 5XX08 (XX has to be filled in wit the system number). In the figure above, you can see screenshots of these tools.
These are mentioned for reasons of completeness. For a detailed explanation of these tools, refer to course ADM200 Administration AS Java.
For system oriented operation the SAP Management Console (SAP MC) provides a common framework for centralized system management. It allows you to monitor and perform basic administration tasks on the SAP system centrally, thus simplifying system administration. Starting with SAP NetWeaver 7.1 the SAP MC is available as a Java applet that can be run from any Web browser supporting Java.
Thus, you can administer remote systems without needing a local installation.
To be able to start the SAP MC applet make sure that you have fulfilled the following requirements:
• You have Java Runtime Environment (JRE) 1.4.2 or higher installed.
• Your Web browser supports Java.
• Your Web browser’s Java plug-in is installed and activated.
In your Web browser, execute the following URL: http://hostname:5xx13. For example, if the instance number is 60, in this case the port is 56013. This starts the SAP MC Java applet.

• start up the SAP Management Console
• check the CIM model version and the CR version on your SLD
• check the existing parameters of category MONITOR - Integration Engine Configuration
Business Example
Get familiar with various tools.
Task:
[Enter a high level description of the task the learner will perform in this exercise.]
1. Start the NetWeaver Administrator for PI from the Tools page nad browse around.
2. Start the NetWeaver Administrator for PI directly in the Internet Browser via suffix /nwapi.
3. Start the SAP Management Console for stack administration of the training system.
4. Open the SLD and navigate to the Administration part to check which CIM model version and CR versionl is installed on the SLD assigned to the training system.

Solution 2: SAP NetWeaver PI Operation Tasks and Tools
Task:
[Enter a high level description of the task the learner will perform in this exercise.]
1. Start the NetWeaver Administrator for PI from the Tools page nad browse around.
a) Logon via SAPGUI to the training system and call transaction SXMB_IFR. Start NetWeaver Administrator under Configuration and Monitoring.
2. Start the NetWeaver Administrator for PI directly in the Internet Browser via suffix /nwapi.
a) URL: http://<full qualified hostname>:<HTTP port>/nwapi
3. Start the SAP Management Console for stack administration of the training system.
a) URL: http://<full qualified hostname>:5xx13 with xx = Instance Number.
4. Open the SLD and navigate to the Administration part to check which CIM model version and CR versionl is installed on the SLD assigned to the training system.
