ORA-28509: unable to establish a connection to non-Oracle system
Cause:
Initialization of a database link to a non-Oracle system failed to connect
to the Heterogeneous Services agent process for this non-Oracle system.
Action:
Check the Net8 service name definition in the following places:
n in the USING clause of the CREATE DATABASE LINK statement
n in the TNSNAMES.ORA file
n in the Oracle Names Server
Possible reasons for name mismatches are:
n The USING clause in the CREATE DATABASE LINK statement has to
match the service name defined in TNSNAMES.ORA or in the Oracle
Names Server
n The service name definition to connect to a non-Oracle system, requires
additional Heterogeneous Services information. This information is agent
specific.Please see the agent’s Installation and User’s Guide for more infor-mation.
n The protocol-specific information in the service name definition must
match the protocol-specific definition of the listener.
n The SID=<name>; in the service name definition (TNSNAMES.ORA file or
in Oracle Names Server) must match the value in the LISTENER.ORA file
for the responding listener.
