.Using Oracle Heterogeneous Services Connectivity to SQL Server :ORA-02068

Question

Hi,
I using oracle HS to connect sql server but error ora-02068: following server from HSSQL and ORA-03135 connection lost contact.
step by step
1. Create the init.ora file = initHSSQL.ora
HS_FDS_CONNECT_INFO = HSSQL
HS_FDS_TRACE_LEVEL = OFF
2. modified listener.ora file
SID_LIST_LISTENERHSSQL =
(SID_LIST =
(SID_DESC=
(SID_NAME=HSSQL)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM=hsodbc)
LISTENERHSSQL =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = CEPITA1403.siam.local)(PORT = 1521))
and start listernerHSSQL = pass
3.modified tnsname.ora :
HSSQL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = CEPITA1403.siam.local)(PORT = 1521))
(CONNECT_DATA =
(SID = HSSQL)
(HS = OK)
and test by tnsping HSSQL = OK
4.setup ODBC SQL Server
Start --> Control Panel --> Administrative Tools --> Data Sources (ODBC)
Click on the ‘System DSN’ tab.
Click ‘Add’.
Name HSSQL
Click ‘Test Data Source…’.--> Pass
5
create public database link HSSQL
connect to sa
identified by xxxxxxxx
using 'HSSQL';
Database Link created.
6. select * from ACCOUNT_CODE@HSSQL;
show error message : ora-02068: following server from HSSQL and ORA-03135 connection lost contact.
Please let me know.

Answer 1

Do you have all of your parameter files set up correctly?
You need to have a hsora file in the hs/admin directory for ioi for instance, initioiDB.ora. In this file you need to set up your hs init parameters. This is an example of what's in one of mine:
HS_FDS_CONNECT_INFO = Mapics
HS_DB_NAME = MAPICS
HS_DB_DOMAIN = WORLD
HS_FDS_TRACE_LEVEL = ON
The you need to have an entry in the tnsnames.ora file in the network/admin directory for hsodbcxtrad. The sid should be set to ioiDB.
You can find documentation on how to manage heterogenous services in the online documentation.

I have been trying to set up a database link between Oracle and SQL Server, currently both on the same Windows NT machine.
I managed to create the link as follows:
CREATE PUBLIC DATABASE LINK ioi
CONNECT TO IOItest IDENTIFIED BY mba
USING 'hsodbcxtrad';
The link is created successfully.
I then try to run a query and get the following error :
select * from dealer@ioi
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC]DRV_InitTdp: [Microsoft][ODBC SQL Server
Driver][SQL Server]Login failed for user '\'. (SQL State: 28000; SQL Code:
18456)
ORA-02063: preceding 2 lines from IOI
I have added a UID and PWD to the registry settings for the SQL Server DSN but this makes no difference. Do I need to specify a username and password somewhere else ?
Thanks
