ORA-28500 connection from ORACLE to non-Oracle system.


Applies to: Oracle Database Gateway, Oracle Database Link, Microsoft SQL Server Standard.

Date created: October 9, 2019.
 

Problem Description.
 

Trying to create an Oracle dblink (Database Link) using Oracle Database Gateway to connect an Oracle database server to a database located on a Microsoft SQL Server instance, we decided to test using below statement:
 

SQL> select sysdate from dual@DOMINIOCOOP;

select sysdate from dual@DOMINIOCOOP
 

But the test was not successful, and we received the following error:


ERROR at line 1:

ORA-28500: connection from ORACLE to a non-Oracle system returned this message:

[Oracle][ODBC SQL Server Driver][libssclient24]General network error. Check

your network documentation. {08001,NativeErr = 11}[Oracle][ODBC SQL Server

Driver][libssclient24]ConnectionOpen (()). {01000,NativeErr = 11}[Oracle][ODBC

SQL Server Driver]Invalid connection string attribute {01S00}

ORA-02063: preceding 2 lines from DOMINIOCOOP

 


Cause.


Looking at the parameters of the dblink I found that the port number was wrong as shown below:


[oracle@alberto admin]$ more initPRUEBA002TEST.ora

# This is a customized agent init file that contains the HS parameters

# that are needed for the Database Gateway for Microsoft SQL Server



#

# HS init parameters

#

HS_FDS_CONNECT_INFO=10.0.0.188:1435//PRUEBA002

# alternate connect format is hostname/serverinstance/databasename

HS_FDS_TRACE_LEVEL=OFF

HS_FDS_RECOVERY_ACCOUNT=RECOVER

HS_FDS_RECOVERY_PWD=RECOVER



[oracle@alberto admin]$
 

 


Solution.


The SQL Server instance was a default instance, thus the tcp port is 1433. Parameters of the dblink should be modified as shown below:


[oracle@alberto admin]$ more initPRUEBA002TEST.ora

# This is a customized agent init file that contains the HS parameters

# that are needed for the Database Gateway for Microsoft SQL Server



#

# HS init parameters

#

HS_FDS_CONNECT_INFO=10.0.0.188:1433//PRUEBA002

# alternate connect format is hostname/serverinstance/databasename

HS_FDS_TRACE_LEVEL=OFF

HS_FDS_RECOVERY_ACCOUNT=RECOVER

HS_FDS_RECOVERY_PWD=RECOVER



[oracle@alberto admin]$
