Actions: Turn on tracing and re-execute the operation. Evaluate the contents of the trace file to diagnose the problem. If you can , look at what may have changed. It worked yesterday and today not then its something that has changed. I know its obvious but... Peter Hi list, I have a curious problem. I have installed Oracle 7.3.4.5.0 and Oracle 8.1.5 on same NT 4.0 Server, SP5. I have two listeners, one for Oracle 7 and one for Oracle 8. This configuration works fine since 1,5 years, but today, after rebooting the NT server, I got the following problem: When I start the Oracle 7 instance and listener I can connect one time to the database, but only once. If I restart sqlplus and try to connect the second time to Oracle 7 instance, I get ORA-12560 error. At the NT server I get know error in listener.log, alert.log, event protocol or system protocol. This is very urgent, cause users are waiting for this instance.
