I am trying to connect to oracle7 (7.3.4) server running on sco unix from Oracle8.0.5 running on linux. I get ora-12505 error.
On the server side, the listner.log file says connection established.
my tnsnames.ora (on linux) is as follows: SCOMACHINE.BOGUS.COM =
(DESCRIPTION =
(ADDRESS = (PROTOCOL=TCP)(HOST=10.14.2.9)(PORT=1521))
(CONNECT_DATA=(SID=WG73))

)
when I try sqlplus scott/tiger_at_SCOMACHINE.BOGUS.COM I get the above error.
The listener log file on SCO UNIX shows everything is Ok The sqlnet.log file on linux machine shows the following: TNS-12204 TNS recieved data refused from an application TNS-12564 TNS: connection refused.
The listener.log file on oracle7 server machine( sco unix ) says connection established.
What are the possible causes for this "connection refused". Please help me in overcoming these problmes. Thanks in advance
Rajendra
