Answer / guest

Cause: The control program was unable to find a TNSNAMES.ORA
file and was unable to find a default name server in
SQLNET.ORA. The control program will operate in this state,
but will be unable to resolve any names until a default
server has been set, and that server must be set using its
raw TNS address.

Action: 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. The first server in the preferred-server list
must be running, and there must be network connectivity
between the control program and that server. Alternatively,
a TNSNAMES.ORA file with valid name server information must
exist in the correct system-specific location.
