Cause: An unexpected end-of-file was processed on the communication channel. The problem
could not be handled by the Net8, two task, software. This message could occur if the
shadow two-task process associated with a Net8 connect has terminated abnormally, or if
there is a physical failure of the interprocess communication vehicle, that is, the
network or server machine went down. 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: If this message occurs during a connection attempt, check the setup files for
the appropriate Net8 driver and confirm Net8 software is correctly installed on the
server. If the message occurs after a connection is well established, and the error is
not due to a physical failure, check if a trace file was generated on the server at
failure time. Existence of a trace file may suggest an Oracle internal error that
requires the assistance of customer support.
