after i installed the SP4 Patch for SAP J2EE Engine 6.30, i can´t login via the Config Tool to database. I want to perform the Action "Activate the Emergency User SAP*". I´ll connect with the default J2EE Database User, in our case SAPC11DB via Datase URL (maxDB 184.108.40.206). From other Tools i can connect to the database with the use URL, JDBC Driver, User and password. The Config Tools hang with Message "Connecting to database...".
