Heterogeneous Connectivity Problem

Question

I want to access the data in sqlserver from oracle use Generic Connectivity
machine A:WINDOWS NT SERVER,SQLSERVER 7.0
machine B:SUN SPARC,Solaris 8,ORACLE8.17
My step below:
1.Create System DSN on machine A, NAME:ssodbc,test/test,PORT 1433 OK
2.Install ODBC for SQLSERVER On machine B,DataDirect Connect for ODBC 4.1
UNIX Server(Solaris 7,8) and Service Pack 1,OK,then config the system
information fileFODBC.INI

6.create database link hsodbcCOK
7.lsnrctl stop OK!
lsnrctl start Ok!
tnsping hsodbc !!!!
TNS-03506:Failed to create address binding
8.test the ODBC if okF

WHY??
1.IN use Generic ConnectivityCwhether config the ODBC on oracle side?
2.what Wire Protocol isH
thanksI

Xu,
When creating the DB link you need to specify the username and password to use to connect.
