Hi

Before you start the EHP Installation please check your Oracle JDBC driver.
The Software Update Manager takes the JDBC driver from the location specified in entry "rdbms.driverLocation" within file "/usr/sap/<SID>/<INSTANCE<nr>/j2ee/cluster/bootstrap/bootstrap.property". The driver specified in that entry is then copied to directory "SUM/java/lib" during the prepare process in the phase "READ_DB_DRIVER_LOCATION".
Later on, during the phases: "DETERMINE_JAVA_PORTS" or "GET_DMT_DB_INF", you may encounter the following errors in case of an outdated JDBC driver specified in the above mentioned bootstrap.property file:
====== error fragment 1 =====
Could not set up a database connection. See previous messages.
