Answer by Edward Stoever:
Is there a listener running? Have you run the
netca program to
configure and start the listener? The Oracle docs note that you should troubleshoot
the ORA-12560 by tracing the connection:
ORA-12560:
TNS: protocol adapter error
Cause:
A generic protocol adapter error occurred.
Action: Check addresses used for proper protocol
specification. Before reporting this error, look at
the error stack and check for lower level transport
errors. For further details, turn on tracing and re-execute the operation. Turn off tracing when the
operation is complete.
MOSC Note: 117976.1 offers tips
for diagnosing the TNS-12560 error noting that the
TNS-12560 is in the TNS transport layer and the
TNS-12560 may only be a symptom of a lower-level
network error as listed in MOSC Note 39662.1.
You can use MOSC Note 39774.1 to
get a SQL*Net trace or follow
these instructions for
getting a SQL*Net trace.
