Multibyte issue in database link with sql server

Hi Gurus,
Greetings!!!
I need to transfer data from Microsoft SQL Server 2005 to Oracle DAtabase 10g(AL32UTF8 characterset). I achieved it using Heterogeneous Connectivity. I can now issue queries but unfortunately i got an issue in displaying multibyte characters. I thought of using another Tool that can display multibyte data but it did not help. I even tried setting the initialization parameter HS_LANGUAGE to different characterset but still not able to display. Kindly help and advise how to resolve the said issue.
Many Thanks in Advance,
Benjie

What is the exact issue you're talking about?
Can you explain it or show us a sort of it with a sample output?
MS SQL Server is not our daily bread so we may not know how it works with Oracle and what problems are there in their interconnectivity, but we may tell you what may be the reason of a behavior that causes the issues for your purpose.
Bye Alessandro

Strange problem with an Oracle database link to SQL Server

Hi gurus,
Please help me on this problem.
We have an Oracle 10R2 database link to a SQL Server 2000 database. I can select count(*) from The_SQL_Server_Table@myOracleLink, and I can describe The_SQL_Server_Table@myOracleLink, but I cannot select Column1 from The_SQL_Server_Table@myOracleLink! I am getting the ORA-00904: "COLUMN1": invalid identifier error.
Could anyone tell me what is wrong here? By the way, the same user name can select all the columns in The_SQL_Server_Table through ODBC from the client app. But I need the DB link to work with some Oracle stored functions.
Thank you!

Creating a database link to SQL server

Hi All,
How can I create a database link from Oracle9i Enterprise Edition Release 9.2.0.1.0 DB to MS SQL Server database.
Thanking You

It depends on your requirements.
You can use either Generic Connectivity or Transparent Gateways.

Waiting for help. What thing im missing.....

Hi Naeem,
You have said the install setup is -
ORACLE_HOME = D:\Oracle\Product\11.2.0\dbhome
GATEWAY_HOME = D:\Oracle\Product\11.2.0\tg
but in the listener.ora you have set ORACLE_HOME for the gateway as -
(ORACLE_HOME = D:\Oracle\Product\11.2.0\dbhome)
To use DG4ODBC installed in the 'tg' ORACLE_HOME then you should configure a listener in the gateway OH -
D:\Oracle\Product\11.2.0\tg\network\admin
and start this listener. This listener will need to use a different port from the RDBMS listener in the other OH.
Change the gateway tnsnames.ora entry used by the RDBMS to reflect this port change.
One other point - SQL*Server is case sensitive so you may need to create the database link as -
create database link sqlserver connect to "uoracle" identified by "uoracle" using 'sqlserver';
if the user/password are defined in lower case in SQL*Server.
Also, the same for object names depending on the SQL*Server configuration -
select "column_name" from "owner"."table_name"@sqlserver ;
Regards,
Mike

DATABASE LINK FOR SQL SERVER

Hi all,
We are running SAP 4.7C with oracle database. For other oracle (non-sap) we are using DBCO to get/put data. Now we have to do the same in SQL server also. In addition to SAP standard table we are sending data of customer table (Z & Y series). Can anybody guide me how to send / receive data using bapi/rfc or some other method.
regards
balakumar

Hi!
For using native-SQL with MSSQL database you have to make your database requests from application server resides on windows platform. So, your basis people have to set up one more windows-based application server instance. There is no impact on backend R/3 database.

Maxim.

Database Adapter with sql server connection cannot import user tables

Hi,
In jdeveloper 11g, I tried to create a sql server database connection, i could create the connection, i could see the tables and navigate through the data in
Database navigator section. But while trying to import the tables in the Database adapter to do polling operation, It displays only the system tables like this
syscolumns (dbo)
syscomments (dbo)
sysdepends (dbo)
sysfilegroups (dbo)
sysfiles (dbo)
sysforeignkeys (dbo)
sysfulltextcatalogs (dbo)
sysindexes (dbo)
sysindexkeys (dbo)
sysmembers (dbo)
sysobjects (dbo)
syspermissions (dbo)
sysprotects (dbo)
sysreferences (dbo)
systypes (dbo)
sysusers (dbo)
I am not understanding this wierd bahaviour of jdeveloper.
please advise.
-Chaitu
Edited by: chaitu123 on May 13, 2010 9:16 AM

This is NOT related solely to the SOA Suite. The same behavior appears in the Connections Navigator.
IMHO, this is related to how JDeveloper is parsing the .getMetaData() response.

How to create a database link to SQL Server from a RAC environment

We have a 4 node RAC running 11.2.0.3 binaries on 64-bit linux.
Grid owns the listener named listener.
Oracle owns the database.

Thanks all! But I tried to configure and I am getting
TNS-01201: Listener cannot find executable /u01/app/oracle/product/11.2.0.3/dbhome_1/bin/InfoEdb10 for SID InfoEdb10
Listener failed to start. See the error message(s) above...
So! What I did was
1. Configure the odbc from the OS (only one node) and create the DSN and its odbc files. connectivity works from Operating Systems.
2. Create the listener entry (under GRID) user.
3. Create the remotedb.ora file under $ORACLE_HOME/hs/admin
--- Here is listener.ora file
LISTENER_NODE1_TG =

DB Link to SQL Server (11gR2 64-bit Windows 7)

Without going into all the gruesome details, it is mostly straightforward to set up a DB Link to SQL Server from an Oracle 10 instance on 32 bit Windows 7. However I simply cannot get the link to work on 11gR2. I tried the simplistic ds4odbc interface and the more complex SQL Server gateway. Nothing works. The connection always times out. Has anyone been able to create a SQL Server DB link from 11gR2 on Windows 7? (The Oracle instance is 32 bit. The OS is 64 bit). I know Win7 is unsupported at present.

Hi,
first of all you need to check the ODBC connectivity between Oracle and SQL Server and the Data source,try to load data from oracle to Sql Server to check the ODBC connection is working properly and then create database link from sql server to oracle ,you can create stored procedures in SQL server to get data from Oracle to sql server or Oracle PL/SQL Packages to data from sql server to Oracle Database
To setup ODBC and datasource
see this link
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
and then create link server in sql server after you test connenction with oracle

ODBC Link ans SQL Server

Hi!
So I tried to create a ODBC link with SQL server, but there is a problem during the authentification process.
When I try to use authentification thanks to SQL server, even with 'sa' user enabled, this error shows up
Connection failed:
SQLState: '28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'myUser'.
When I try to use authentification with Windows ID, another error shows up :
Connection faled:
SQLState: '28000'
SQL Server Error: 18452
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.
The server is a VPS server and there is no domain to configure.
I already tried to switch to mixed authentification, with it I can easily connect to SQL server with SQL server Management Studio. I also already browsed SQL Server Configuration Manager in order to set a static (not dynamic) port, TCP/IP are enabled in SQL
server Network Configuration / Protocols for SQLEXPRESS but it still doesn't work. Ofc I restarted SQL server several times and I even tried to uninstall/reinstall it.
Finally, this error shows up when I start SQL Server agent with SQL server Configuration Manager.
>The request failed or the service did not respond in a timely fashion. Consult the event log or other applicable error logs for details.
I tried to find out what is the problem by reading the logs but there is nothing about the failed authentification attempts there. It only shows some services starting or stopping.
I read somewhere that it the VIA protocol could be the problem, but I can't find it anywhere in SQL Server Configuration Manager.
I've been struggling for days with this. you're my only hope
thanks!

I juste forgot to explain that I have to do this for a client who will use a software of my company and this software needs this ODBC link to communicate with SQL Server. Also the users will connect to the server in TSE (so the application will be on the
same server than SQL Server). I don't know if this detail is important but I prefer specify.
"If it works in SSMS to connect with a SQL Login, then it should work with ODBC by using the same server name/credentials from the sam Client."
I entered 'sa' user and another user that I created in SQL Server but I have the same error (login fail for user)
"Are remote Connections enabled? Is a Firewall running on server and/or Client side? If so unblock the required TCP and UDP ports."
Remote Connections are enabled on the server and there's just Windows Firewall on the server. I unblocked resquired TCP and UDP Ports. Even with the Windows Firewall turned off I have this problem.

Variable database name in SQL Server query using Oracle database link

Hi All,
I have an ApEx 4.1 app running on 11g x64 (11.2.0.1) on Windows Server 2008 x64, and I have some data integration points with a SQL Server (2005 and 2008) that I need to establish. I have configured the database link with dg4odbc and it works beautifully... I can execute queries against the SQL Server database without any problems using the database link.
However, there is a scenario where the SQL Server database name is dynamic, and I need to generate it on the fly in a PL/SQL block, and then use that in a dynamic SQL query (all of this in ApEx). This is where I run into problems... when I am querying the default database based on the ODBC connection and I don't have to specify the database name, there is no issue. But when I need to access one of several other non-default databases, I keep receiving the "invalid table" error.
This runs fine:* (note that "fv" is the name of my database link)
v_query1 := 'select "ReleaseDate" from dbo.Schedules@fv where dbo.Schedules."SchedID" = :schedule';
EXECUTE IMMEDIATE v_query1 into rel_date using schedule;
I then take that rel_date variable, convert to a varchar2 (rel_date_char), and then use it as the database name in the next query...
This returns an error_ (Error ORA-00903: invalid table name)
v_query2 := 'select "PARTNO" from :rel_date_char.dbo.ProdDetails@fv where "SchedID" = :schedule and "UnitID" = :unit
and "MasterKey" = :master and "ParentKey" = :parent';
EXECUTE IMMEDIATE v_query2 into part_number using schedule, unit, master, parent;
I have also tried using all of the following to no avail:
'select "PARTNO" from ' || :rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from ' || @rel_date_char || '.dbo.ProdDetails@fv where "SchedID"...
'select "PARTNO" from @rel_date_char.dbo.ProdDetails@fv where "SchedID"...
Is there a way to do this in PL/SQL?
Thanks for any help!

Just did a test using passthrough:
SQL> set serveroutput on
SQL> declare
2 val varchar2(100);
3 c integer;
4 nr integer;
5 begin
6 c:= dbms_hs_passthrough.open_cursor@FREETDS_DG4ODBC_EMGTW_11_2_0_3;
7 dbms_hs_passthrough.parse@FREETDS_DG4ODBC_EMGTW_11_2_0_3 (c, 'select count(*) from EMP');
8 LOOP
9 nr:= DBMS_Hs_Passthrough.fetch_row@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c);
10 exit when nr=0;
11 dbms_hs_passthrough.get_value@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c,1,val);
12 dbms_output.put_line(val);
13 end loop;
14 dbms_hs_passthrough.close_cursor@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c);
15 end;
16 /

So all 3 ways work for me.

Now using variables to perform the select:
SQL> declare
2 val varchar2(100);
3 c integer;
4 nr integer;
5 tabname varchar2(20) :='EMP';
6 ownr varchar2(20) :='dbo';
7 dbname varchar2(20) :='gateway';
8 begin
9 c:= dbms_hs_passthrough.open_cursor@FREETDS_DG4ODBC_EMGTW_11_2_0_3;
10 dbms_hs_passthrough.parse@FREETDS_DG4ODBC_EMGTW_11_2_0_3 (c, 'SELECT count(*) FROM '||dbname||'.'|| ownr || '.'||tabname||'');
11 LOOP
12 nr:= DBMS_Hs_Passthrough.fetch_row@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c);
13 exit when nr=0;
14 dbms_hs_passthrough.get_value@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c,1,val);
15 dbms_output.put_line(val);
16 end loop;
17 dbms_hs_passthrough.close_cursor@FREETDS_DG4ODBC_EMGTW_11_2_0_3(c);
18 end;
19 /
24576
PL/SQL procedure successfully completed.
=> instead of executing the statement using "execute Immediate" we have to use PASTHROUGH package to pass the statement to the SQL Server.

Difference between database features - SQL Server 2008 R2 navtive vs SQL Server 2012 with SQL Server 2008 compatibility set?

I am investigating the impact of upgrading from SQL Server 2008 R2 to SQL Server 2012. To reduce the impact of the upgrade, I am planning to restore / create our application database onto SQL Server 2012 with compatibility level 100 (SQL Server 2008 and
SQL Server 2008 R2).
Are there any differences in feature support for database running in native mode on SQL Server 2008 R2 vs a database installed on SQL Server 2012 with compatibility level 100 set?

Are there any differences in feature support for database running in native mode on SQL Server 2008 R2 vs a database installed on SQL Server 2012 with compatibility level 100 set?
Yes there can be difference and impact there are few features deprecated in SQL Server 2012 you must be aware about that. Please see
Deprecated Database Features in SQL Server 2012
Deprecated SQL Server features in SQL Server 2012
After you migrate database to 2012 please don't move ahead with production unless you have tested your application to new created database
