Answer / guest

Cause: s for the failure. The control program's SQLNET.ORA
file must exist in the correct system-specific location, and
must be readable by the control program. The file must
contain a names.preferred_servers entry with valid name
server addresses. If the user has changed managed servers
with the SET SERVER command, the new server must be running,
and must be able to resolve the address or forward the
request to another server which can resolve the address.
Alternatively, a TNSNAMES.ORA file with valid name server
names and addresses must exist in the correct
system-specific location.

Action: For further details, turn on tracing and re-execute
the failing operation. If the error persists, contact
Worldwide Customer Support.
