TNS-12560: TNS:protocol adapter error - Of a different sort

Question

Hi ,
Have a unique problem.
System :- Win 2K
I have installed 9iDB & 9iDS. They were working perfectly fine. I was able to connect to DB from forms. But due to some restrictions i had to resort to 6i forms.
Now i installed 6i forms on the same machine. But when i try to connect to DB i get the TNS:Protocol Adapter error. I am sure the instance and the listener is up and running. Because still i am able to connect from 9i forms. The DB name is MYDB.
The error i am getting is :-
========================
Fatal NI connect error 12203, connecting to:
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle80)(ARGV0=oracle80ORCL)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))')))(CONNECT_DATA=(SID=ORCL)(CID=(PROGRAM=C:\Oracle6i\BIN\PLUS80W.EXE)(HOST=xxx.xxx.xxx.xxx)(USER=Myself))))
VERSION INFORMATION:
     TNS for 32-bit Windows: Version 8.0.6.0.0 - Production
     Oracle Bequeath NT Protocol Adapter for 32-bit Windows: Version 8.0.6.0.0 - Production

Tracing not turned on.
Tns error struct:

ns secondary err code: 0
nt main err code: 530
TNS-00530: Protocol adapter error

===============================
Can someone please guide me as to how i can connect to my 9iDB from 6iforms.
Thanks & Regards,

Oracle is a bit touchy with tnsnames.ora spelling. I copied your entry, just changing names :
MYDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
$ sqlplus scott/tiger@mydb

ERROR:
ORA-12154: TNS:could not resolve service nameThen I change MYDB entry, just adding some spaces :
MYDB =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
$ sqlplus scott/tiger@mydb

Did you try copying 9iDS SQLNET.ORA and TNSNAMES.ORA to 6i Home ?
