Linked Server in MS SQL Server 7.0

I created a linked server in MS SQL Server 7.0. DB Provider is OLE DB Provider for Oracle 8.1.7. All is working, but when I try to make select, insert or update from the Oracle table which conains data time NUMERIC (with size and scale 0) OLE DB Provider returns the Error message:
OLE DB provider 'OraOLEDB.Oracle' supplied invalid metadata for column %COLUMN_NAME%. The data type is not supported.
I've already downloaded and insatalled the new version of OLE DB Provider, but the problem still present.

Did you solve your Problem? I'm having exact same problem in my application. Can you or someone else help me?
Thanx

Oracle Linked Server problem in SQL Server

I'm using the MS OLE DB Provider for Oracle in my SQL Server linking an Oracle 9i server to the SQL Server 2000 server. I get the following error when I try to execute a query thru the SQL Server Query Analyzer:
[OLE/DB Provider 'MSDAORA' IOpenRowset::OpenRowset returned 0x80004005: ]
I can however define an ODBC connection and use DTS to get to the Oracle database just fine from the SQL Server machine. I need the linked server query to work though since I'll need it for a new application.
Any help is very much appreciated.
Thanks.
Anja

I guess I'll answer my own question. I found that the setting SQL Query Analyzer was set to "Implicit Transactions" in the current connection properties. When I turned that off the query ran fine

Creation of database link from oracle to sql server 2000

Hi
I need to create a database link from oracle to sql server 2000.

Assuming your Oracle database is running on Windows, you can set up a database link using ODBC using Heterogeneous Services and Generic Connectivity, but there are some functional limitations (i.e. no two-phase commits). If you can live with those limitations but aren't on Windows, you can generally purchase an ODBC driver for your operating system that will connect to SQL Server through someone like DataDirect and still use Generic Connectivity. If you cannot live with those limitations, you can purchase one of Oracle's Transparent Gateway products (though this can get somewhat pricey).
What version of Oracle are you on?
What operating system(s) are you using?
What are you going to use the database link for?

Creating Database Link from Oracle to SQL Server

I am trying to create a database link from Oracle to SQL Server, and the documentation is about as clear as mud to me. Can anyone send me clear instructions on exactly what I need to do? What needs to be in tnsnames.ora and listener.ora files? Is there anything other than those two files that needs to be set up? Do I set up an ODBC connection? Anything else? I want to execute queries against a SQL Server database and load data into Oracle database.
Thanks so much,
Susan

These are the instructions from an old document I created. The steps are same for SQL Server and Sybase. Hope it helps.
The 9i Transparent Gateway Software is in Oracle Software CD -> oracle9i database -> Custom -> Oracle Transparent Gateways
The gateway can be installed on the same machine as the Oracle database or
on the Sybase server or on a third machine as a stand-alone.
We have installed the gateway software in one of oracle database
servers in a separate oracle home.
These are the steps involved in configuring a gateway to a Sybase database
1.     Install Sybase client and Gateway software on the Gateway Server
2.     Configure <initsidfile> in the Gateway Server's <gatewayhome>
     /u00/app/oracle/product/9.2.0/tg4sybs/admin/init<gatewaysid>.ora
Sybase server and database information is required for this step.
eg: HS_FDS_CONNECT_INFO=USTRUD01.uwd
3.     Add an entry in listener.ora in <listnenerhome>
     (/u00/app/oracle/product/9.0.1/network/admin/listener.ora) for the <gatewaysid>
4.     Edit the tnsnames file (/u00/app/oracle/product/9.0.1/network/admin/tnsnames.ora)
to add an entry <tnsalias> for the <gatewaysid>
5.     Create a database link to the Sybase database in the oracle database.
The steps for creating the database link are
a. create a login oracle_tgw in the sybase server
b. add the user to the sybase database with the necessary privilege on the tables
c. create the database link in the required oracle database using the command
     "create public database link <dblinkname> connect to oracle_tgw identified by password using 'tnsalias'; "
6.     Restart the gateway listener.

How to create database link between oracle and SQL Server

Hello Everyone,
Here i have Oracle Database 9i and SQL Server 2005 databases.
I have some tables in sql server db and i want to access from Oracle.
How to create a database link between these two servers
Thanks,

Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a)     Oracle 10g software
b)     User account to access SQL Server database (sa/abc@123!)
c)     Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1)     Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2)     Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3)     Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST    <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4)     Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =

(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5)     Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6)     Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora
something=
(DESCRIPTION=

Linking a pervasive server to MS SQL server

I have a Pervasive SQL server that hosts our accounting software and I want to link it to a SQL server so that I can use SQL to generate some reports and pull some data
without taxing the pervasive server any more than it already is. So far I have been able to get the server to link and connect and I can see the tables and databases on the pervasive server but I am unable to select anything from the linked server. I
have a linked server set to access the demodata database that pervasive sets up automatically to test and it is named pvswdemodata and when I execute this command I get two errors. The query I am trying to run is
select * from pvswdemodata.demodata..course
The errors I am getting are
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "pvswdemodata" reported an error.
The provider did not give any information about the error.
Msg 7312, Level 16, State 1, Line 1
Invalid use of schema or catalog for OLE DB provider "MSDASQL" for linked server "pvswdemodata".
A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog or schema.
Any help would be really appreciated. Oh and I am running
MS SQL Express 2012 on a Win 8.1 machine connecting to a Pervasive v11 server running win server 2008 R2 both are 64-bit (os and SQL/Pervasive with a 64-bit ODBC driver)

Hello,
Please try the following code:
DECLARE
@QUERY nvarchar(4000)
DECLARE
@TSQL nvarchar(4000)
SET
@TSQL =
'select * from demodata..course'
SET
@QUERY =
'SELECT * FROM OPENQUERY(pvswdemodata, @TSQL)'
EXEC
sp_executesql @QUERY
Hope this helps.

HS_FDS_TRACE_LEVEL = on
3) modified the listener.ora file as below
# listener.ora Network Configuration File: E:\Ora11g\product\11.1.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =

5) restarted the listener
6) created a public database connect
create PUBLIC DATABASE LINK "GALAXY" CONNECT TO "USER" IDENTIFIED by "PWD" USING 'galaxy';

11.2 is beta at the moment. There is no official release date so far.
As DG4ODBC is independant from the Oracle database (or the target database) you can use a 3 machine model:
On the first machine you have your Oracle database, on a second machine running 32bit Windows you can install DG4ODBC and on the 3rd machine you can run your foreign database.
If the SQL Server 2k is installed on a 32bit Windows machine, then you can also install DG4ODBC on this machine.
In general the connection from an Oracle database to the DG4ODBC machine is done using SDQL*Net. The listener responsible for DG4ODBC will then load the DG4ODBC executable which will connect to the SQL Server using SQL Server ODBC driver.

Replication between Oracle Server and MS SQL Server

Hello,
Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
Thank you.

It could be very interesting.Sorry Viacheslav, even I couldn't find anything for the same. I am not sure that it can be done or not, I haven't heard anyone in my contact doing so. The only place where I have seen Streams being used around me is within Oracle db only. May be someone else can help if he/she has done it.

Changes required to switch from SQL Server 2000 to SQL Server 2005?

I'm converting a legacy app from SQL Server 2000 to SQL Server 2005. The app is written in VB6 and utilizes CR 8 OCX. When I invoke a report from VB I'm getting Error# 20599 Cannot open SQL server. I redefined the ODBC DSN specifying Windows Authentication, and the SQL Server instance supports mixed mode.
Searching for the error, I found an article that suggests I need p2sodbc8.zip, but I can't find a link to it in the Downloads area.
Would greatly appreciate any help at all - including a link to p2sodbc8.zip if that's the likely resolution.
Thanks in advance,
Pete

Hi Peter,
As you are having issue with SDK's.
I would suggest you to post your question in
Business Objects SDK Application Development » [Legacy Application Development SDKs|;
That forum is monitored by qualified technicians and you will get a faster response there. Also, all SDK queries remain in one place and thus can be easily searched in one place.
Thank you for your understanding,

It is compatible Obi 11g with Windows Server 2012 and Sql Server 2012?

Hi every
Please help with two questions.
1. - Obi 11g is supported on Windows Server 2012 and SQL Server 2012?
There a compatibility matrix which mention compatibility with versions 2012?
2. - is feasible to install Obi 11g in separate server and install weblogic on another server?
I appreciate the prompt response
Regards
Pedro

Hi Pedro,
As of November 2012 Compatibility Matrix released by Oracle for OBI 11.1.1.x Windows 2012 and SQL Server 2012 were not supported. It was supported on 2008 Windows and SQL Server.
We can have weblogic and OBI server's on 2 different machines. The approach is to opt software only install. the link below will give more details:

SQL Server 2008 to SQL Server 2012

My server crashed with SQL Server 2008 on it. I am replacing it with a new machine with SQL Server 2012. How do I restore my old SQL database to my new machine?

Have a look at using Restore Header Only to look at the contents of your backup to confirm its contents. (http://technet.microsoft.com/en-us/library/ms178536.aspx)
From this then look at the restore database here -
http://technet.microsoft.com/en-us/library/ms186858.aspx
From confirming the contents of your backup you will need to select the appropriate position number (from the restore header only) and link that with the File Number (from the restore)
