The Monitor Server installation process must stop and start the WebSphere® Application Server several times during installation. If the WebSphere Application Server does not stop successfully, the installation process will fail.
To check for this problem, look for the following error in your <WebSphere_Process_Server_Home>\profiles\monitor\logs\server1\ stopServer.log or SystemOut.log:
WsServerStop E ADMU3007E: Exception com.ibm.websphere.management.exception.ConnectorException: ADMC0016E: The system cannot create a SOAP connector to connect to host <Host_Name> at port <Port_Number>
If you see this error or other errors associated with stopping the server, refer to the WebSphere Application Server Version 6.0 Information Center for troubleshooting information.
After you have resolved the problem, you must uninstall and reinstall the Monitor Server.
