Decision Roadmap

Prerequisites

You need to have access to the following systems:

●     SAP Knowledge Warehouse (SAP GUI connection)

●     HTTP – connection to the J2EE Engine

●     J2EE Engine directly by terminal server, NetMeeting, PCAnywhere, or Telnet

In order to change configuration settings, you need the appropriate user rights.

Main Tools

Transaction SI24_9

Analysis

Check the  following steps for analyzing and solving the problem:

1.   Check the customizing with transaction SI24_9

...

Log on to your SAP Knowledge Warehouse system using the SAP GUI.

Start transaction SI24_29 and for the document area of your interest (documentation, training, and so on) check the entry in the Web Server column for misspelling.

Additionally, check the HTTP – Port column (default port for the J2EE Engine is 5<SAP instance.no.>00) for correctness.

2.   Is the host reachable where the J2EE machine is running

Open a command window on your machine and enter ping <hostname> to test if the host (identified by hostname) where the J2EE machine is running is reachable. If you get an error, contact your network administrator to fix the problem.

If you have no access to the machine where the problem exists, refer to the relevant PAS of the J2EE Engine.

3.   Accessing the J2EE Engine

Start your browser (such as Internet Explorer, Mozilla, and so on) and enter http://<hostname>:<port>/index.html in the address bar. The port depends on the Customizing of your J2EE Engine (default: 5<instance.no.>00). The start page of the J2EE Engine must be shown. If not, the engine is not started. In this case, start the J2EE Engine.

4.   Accessing SAPIKS2

Start your browser (such as Internet Explorer, Mozilla, and so on) and enter http://<hostname>:<port>/SAPIKS2/jsp/adminShow.jsp in the address bar. The actual configuration of the SAPIKS2 must be shown. If you could access the J2EE Engine but the configuration page is not visible, use the J2EE Engine’s SDM (Software Deployment Manager) to check if the SAPIKS2 has been deployed successfully. The SDM is located on the host where your J2EE Engine is installed in the directory /usr/sap/<Instance>/JC00/SDM/program and is named RemoteGui.bat (for Windows) or RemoteGui.sh (for UNIX). After a successful logon, click on the tab strip SDM Repository and check in the navigation frame if the application KM-KW_JIKS is shown by opening the SspJ2EEEngine navigation item. If it is not available, click on the tab strip Log Viewer to check if the deployment was successful. If not, try to redeploy it. If this fails again, open a SAPNet Frontend (OSS) message.
