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!
Ben

Problem with making a database link.

Hello All
I got a problem with making a database link.
When I execute this query
CREATE PUBLIC DATABASE LINK DBNAME
CONNECT TO database IDENTIFIED BY name
USING 'DBNAME.europe.company.com';
I am using other names because its private information
But when I look at the table dba_db_links I see this
OWNER | DB_LINK | USERNAME |HOST
PUBLIC| DBNAME.europe.company.com| name| DBNAME.europe.company.com
So the DB_Link name is changed. And this causes a problem with my asp website. I get the fault message
ORA-02085: database link DBNAME.europe.company.com connects to DBNAME
Cause: a database link connected to a database with a different name. The connection is rejected.
The global_names = true and I prefer to keep it that way.
So does anyone knows what is wrong about my Query or how I can change the DB_Link name.
Thanks for the support,
Remco

Thanks for the help Mohit
But thats whats I was doing.
The query in the first post is the same as what you are posting.
But by an (for me) unknown reason the database converts DBNAME to DBNAME.europe.company.com

Migrate oracle database to Microsoft sql server 2005

Hi All,
I have to migrate production oracle database to Microsoft sql server 2005. Below are the details:
Oracle database version: 8.1.7.4
Platform : Aix
Kindly help me out

Well, the traditional way would be to dump out all your data from Oracle tables as comma delimited flat files and import into SQL server. Plenty of examples online, like this is one by Mark Powell: http://www.jlcomp.demon.co.uk/faq/flatfile.html
Or if you have the budget you could think about buying a data mapping tool like File-Aid
As mentioned by another poster, you will still need to figure out how to replace all your triggers, stored procedures, etc on your new platform of course.

Problems with query via Database-Link (Oracle 7.3.4)

I made the following simple query via database-link.
select count (*) from [email protected]
I got the result in about 200 miliseconds.
Then I4ve tried the following query.
select * from [email protected]
It took about 2 hours end ended with an error message "ORA-03113: end-of-file on communication channel"
So I made another choice
select * from [email protected] where rownum <=1
Took about 200 miliseconds.
So I made the query again an changed only the number of rownums,until I was at rownum <=8
then it went sleeping again(I've canceled the statement because I didn't want to wait 2 hours again).
We made the same things from another server with the same database-link on the same remote server
and we had no problems.
Any Idea???

No, network is OK!
Other links are running, I have also no problems when I connect directly to the remote server.

Problems with deploying cmproster example using ms sql server as database

hi to all,
im new to ejb and i like to learn by doing the examples given in the j2ee tutorial. i want to deploy the cmproster with a bit of modification...i want to use ms sql server as the database..i have configured the data source and connection pools correctly..and when i run the Client Application there is no error. The database seems fine it was populated correctly..only some of the values become null..
Here is the sample output from the client app:
P7 null null 777.0
P8 null null 65.0
P10 null null 100.0
P6 null null 555.0
P9 null null 100.0
The two columns should be strings...i look at the server.log and there where errors:
Error while getting value from resultset at index 2 as resultType 21columnSqlType=JDO76: 12.Exception java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Invalid Descriptor Index
I think thats the culprit...Can anyone help me on this? tnx
Note:
By the way im using sun.jdbc.odbc.JdbcOdbcDriver for the jdbc driver
Thanx

Hi Michael,
At this time SQL Server 2000 is not certified for WLCS 3.5. Since the
schema has changed between 3.2 and 3.5, running the 3.2 scripts is not a
good idea.
I can tell you that certification is in progress for SQL Server 2000. Your
best bet is to contact your Sales Representative to get an idea of when
certification might be coming.
I hope this helps.

I'm using WebLogic 6.0sp1 with Commerce Server 3.5 and I've successfully

installation, this time using Microsoft SQL Server 2000 as the database
instead of Cloudscape. I've downloaded and installed the BEA jDriver

the db scripts for creating and populating the commerce database? I've

How to share and Access DB (.accdb) with global tables that link to SQL Server tables without having to define ODBC connections on each client PC?

I have an Access DB with quite a few Linked Tables that point to a SQL Server backend db. Currently I am using an ODBC connection defined on my pc, but I want other users to be able to download the .accdb file from a share and run. Will I have
to define this odbc connection on each client's pc? Is there a better way to do this without having to have each client manually set this up on their PC?

Hi Jason,
I think you can automate that process. In each application I use a one-record-table in the FE with a field Connected. Connected is default False.
Starting a database in the development mode ignores this flag. Starting a database in production mode starts, if Not Connected, a procedure to RefreshLink the tables to the BE, and makes Connected = TRUE, so a next startup does not
result in a new RefreshLink.
Instead of a Boolean you could also use a string containing the path, or whatever you want.

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.

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.

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

How to execute remote query by Oracle Database Link

I use Oracle Database Link to query data from SQL Server. The query is like:
select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*
tableA and tableB is large and the result is relatively small. This query executes quickly in SQL Server since indexes are built both on the two tables. But it is very slow on Oracle Database Link to SQL Server.
I guess the join operation is performed on Oracle side not on SQL Server side, thus the indexes are not used. Since I just need the joined result, I prefer to perform the query entirely on SQL Server and get the small result only. But I have no privilege to create views on SQL Sevrer.
I konw that using SQL Server's linked server and OPENQUERY function can achieve this goal. I wonder how to do this on Oracle Database Link. Thanks!

DO NOT DO THIS....specifically:
"select *
from tableA@DL_SqlServer a
join tableB@DL_SqlServer b
on a.ID = b.ID*"
You would be better off to do the following:
create a Materialized View in Oracle and once/day (or as frequently as you feel necessary) pull the data from SQLServer and then do the join locally by creating MV as TABLEA_MV and TABLEB_MV and then have views that have the REALTABLEA and REALTABLEB names that point to these MVs. This can be done without recompiling or changing your code. Trust me, I have seen this sort of thing in the past that completely crippled an IBM mainframe using DB2 along with a major network segment by having this sort of join via DB links. You must understand the ramifications of your "design" and I can tell you for certain that it is a very BAD!!! idea... Fix this before you are issuing another command: "alter DBA update resume/CV;"
The app went into production at 7AM. By 9:30AM, the mainframe had executed more than 10Billion I/O's. It took > 15hrs for the mainframe to recover once we shutdown the app and implemented the view/MV described above.
I will leave it as an excercise for the OP to develop the syntax for this.
