I am installing a J2EE AS system. In the phase "Import Java Dump" I get this error:
Dec 14, 2006 2:04:27 PM com.sap.inst.jload.Jload main
SEVERE: couldn't connect to DB
Dec 14, 2006 2:04:27 PM com.sap.inst.jload.Jload logStackTrace
SEVERE: java.sql.SQLException: Io exception: Invalid number format for port number
tnsping is working perfectly and db is running, so no problems there. I see in similar cases on SDN that you can change something regarding the jdbc driver/oracle client using configtool. But configtool has not yet been installed! That's done in a later step.
