because a user-written program has not logged on. It may happen if communication trouble causes a
disconnection. In addition, this message could occur when ALTER SYSTEM KILL SESSION or
ALTER SYSTEM DISCONNECT SESSION were issued with the IMMEDIATE qualifier because, in
those cases, the client's connection to the database is terminated without waiting for the client to
issue a request.
Action: Try again. If the message recurs and the program is user written, check the program.
