thanks

Compare tnsnames.ora on client with tnsnames.ora on server.
Compare sqlnet.ora on client with sqlnet.ora on server.

Hey, those code tags are pretty cool now, eh?

Hi,

I want to be sure so I copy the same sqlnet.ora and tnsnames.ora and I still have the same problem.

any other thoughts????

what does tnsping say?

c:\>tnsping test

TNS Ping Utility for 32-bit Windows: Version 10.1.0.3.0 - Production on 21-JUN-2

Used TNSNAMES adapter to resolve the alias

TNS-12560: TNS:protocol adapter error


same error when I do the tnsping test.tele.com

You may have copied tnsnames.ora into wrong directory. Notice HOST information in tnsping o/p. It isn't test.test.com (the way it should be).

how about:
ping 168.172.3.1
ping test.tele.com

nslookup test.tele.com
nslookup 168.172.3.1

Also, on test.tele.com, lets see the output from:
lsnrctl status

nah, the default_domain is correct.

Oh, wait. Your service name is test. I think you want that to be your SID:

Code:

---

TEST.TELE.COM =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = TEST.TELE.COM)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID = test)
    )
  )

as I mentioend earlier, I already tried test.tele.com as well and it's doesn't work.

I copied both file from server to client and NO LUCK



Jeff,

I have service_name instead of SID, sorry for the confusing.

do you guys my problem having anything to do with Microsoft Active Directory on the network side?????

I can't think of any other reasons why I can't connect

the problem is most likely with your config files somewhere.

remove the sqlnet.ora temporarily and remove the domain from the connect information
