How to create a linked server to SQL in Oracle?

I am able to create a linked server to Oracle in SQL.. But I do not know the steps to create a linked server too SQL in Oracle.
How to create a linked server to SQL in Oracle? After creating the linked server to SQL, I would like to create triggers in Oracle DB to insert records into SQL DB.

There are 2 products in Oracle you can use to link to a MS SQl Server. The first one is for free and it is called Database Gateway for ODBC. With a suitable 3rd party ODBC driver you can connect to any foreign database. The second gateway is our commercial gateway and it is called Oracle Database Gateway for MS SQL Server. It is designed for MS SQl Server connections and more powerful then Dg4ODBC. It know how to map a lot of Oracle functions to SQL Server equivalents and you can also use it to directly call SQL Server procedures or functions. This dedicated SQL server gateway is also able to participate in distributed transactions.
But again, this is a commercial gateway and you have to purchase a license for that second gateway, the Database Gateway for MS SQl Server.

How to create a Linked Server from SQL Server 2012 to Postgresql

Hi, I am working on a third party application which is using Postgresql version 9 database and I am trying create a linked server in SQL Server 2012 using the below stored procedure.
EXEC master.dbo.sp_addlinkedserver @server = N'LINKEDSERVERPOSTGRES', @srvproduct=N'PostgreSQL',
@provider=N'MSDASQL', @provstr=N'Driver=PostgreSQL;uid=pguser;Server=pghost;database=pgdatabase;pwd=somepassword'
Error: Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server.
I have no clue if a jdbc provider exists in SQL Server to connect to Postgresql or what the right provider is? Could you please let me know if there's a workaround to achieve this.
Thanks in advance............

Have trouble query after creating a linked server from SQL Server 2008 to EXCEL 2007

I created a linked server from SQL Server 2008 Management Studio Express to an EXCEL 2007 workbook using:
sp_addlinkedserver @server='LSERVER_EX0', @srvproduct='EXCELDATA', @provider='Microsoft.ACE.OLEDB.12.0', @datasrc='C:\Temp\abc.xlsx', @provstr='EXCEL 12.0'
The linked server LSERVER_EX0 was created, but I cannot see any table(excel sheet), and when i ran the following to query tables,
sp_tables_ex 'LSERVER_EX0'
I got:Cannot obtain the schema rowset "DBSCHEMA_TABLES" for OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "LSERVER_EX0". The provider supports the interface, but returns a failure code when it is used.
Any hint why?
on another note, i was able to import the EXCEL sheets using the Import and Export Data wizard, but i cannot control the column data type and size in this way.

Open management studio, goto "Server Objects"->"Linked Servers"->Providers, select the provider you use, right click it and in provider options, check "Allow inprocess".

How to create a dedicated-server session (to a oracle database)

Hello!
I've installed Oracle SQL Developer (Rel.: 2.1.1.64.45) and Oracle Instant Client (Rel.: 11.1.0.7), my Client is configured to enable connections using tnsnames.ora or host-/easy-naming (sqlnet.ora-entry: NAMES.DIRECTORY_PATH= (TNSNAMES, HOSTNAME)).
Regardless how I configure a database-connection in SQL Developer, I allways "only" get a shared-server connection (even when using a tnsnames.ora-entry with "...(SERVER = DEDICATED)...").
SQL Developer (any release) in combination with ("fat") client 9.2.0.7 (using tnsnames.ora) creates dedicated-server sessions as wanted.
Is there any setting in SQL Developer which dis- and/or enables dedicated-server sessions or is this a feature/problem of Instant Client 11.1.0.7?
Any ideas and/or suggestions?
(Additional Info: There is no difference in this behavior according to the connected database, I work with databases 9.2.0.7, 10.2.0.3, 10.2.0.4, 11.1.0.6 and 11.2.0.1)
With kind regards
Klaus

Hi,
Take a look at the main [ SQL Developer page on OTN|http://www.oracle.com/technology/products/database/sql_developer/index.html]. There is a link you should find useful, it's the Getting Started link under the Migration section. This explains how to download and setup the drivers you need to correct to non-Oracle databases. There are also links to online demonstrations on how to create connections to these databases. See how you go with that material.
It should help.

How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?

How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?
Let's say the SQL Server and Oracle Database are in the same Company Internet Network.
I have the code, but I do not know how to use it. Such as what is System DSN Name? Where could I get it. What does it look like?
Do I need to install any Oracle Client Software in order to link from SQL Server to Oracle? Or SQL Server has the built-in drivers installed already that I can directly create a Linked Server from SQL Server to Oracle?
I need to know details. Thanks.
USE master
go
EXEC sp_addlinkedserver
     @server  = '{Linked Server Name}'
    ,@srvproduct = '{System DSN Name}'
    ,@provider  = 'MSDASQL'
    ,@datasrc  = '{System DSN Name}'
EXEC sp_addlinkedsrvlogin
     @rmtsrvname = '{Linked Server Name}'
    ,@useself  = 'False'
    ,@locallogin = NULL
    ,@rmtuser  = '{Oracle User Name}'
    ,@rmtpassword = '{Oracle User Password}'

You need an OLE DB provider for Oracle. There is one that ships with Windows, but it only supports very old versions of Oracle. Oracle has an OLE DB provider that you can use. I don't know if it's part of Oracle Client or how it is bundled.
You should not use MSDASQL or any DSN.

Can I create a linked server to this ODBC datasource (odbc driver by Progress OpenEdge) on Sql Server 2000 ?

I installed the Progress OpenEdge ODBC driver for 32 bit database on my win7 workstation -- I used odbcad32.exe located at C:\Windows\SysWOW64 to configure the driver for 32 bit applications -- per the screen Shots here and I am able to connect to the datasource
from Excel Query.
I am able to connect to this ODBC datasource from Excel Query and see all the tables -- as in the screen shot. I can also access this datasource from a C# app.
Question: if I can connect to this ODBC datasource from Excel -- does this mean I should be able to create a linked server to it? I tried the following from SSMS Linked Serber Wizard on a Sql Server 2000 (I have used the Linked server wizard
successfully in the past as well as linking with Tsql SPs). This will at least create a mock Linked server on the Sql server 2000 (this does not work on sql server 2008 -- I tried), but when I try to view the catalogs -- I get the error in the screen
shot below. If the answer to my question is "YES" yes I should be able to create a linked server to this ODBC datasource what is the way to do this? I added the UserID and Password in the Security tab, but I did not see where to add the
port (4000). What do I enter for the Product Name? Can it be arbitrary or does it have to be something specific?
Rich P

Yes, you should be able to set up this as a linked server - from a 32-bit instance of SQL Server. That is, you can't use a 32-bit driver on 64-bit SQL Server. Now, since you have SQL 2000, I assume that this is a 32-bit instance. (But there was a 64-bit
version for Itanium of SQL 2000.)
For the Provider string, I would guess that you should enter something like
Driver={Progress 11.3 OpenEdge Driver}
just like you do in your application code.
Basically, in the provider string, you specify your connection string, except that you take out the provider name, which is a separate parameter to sp_addlinkedserver. Since I know nothing about Progress, I can't give any specific details.
The error message you get is somewhat puzzling, since this refers to SQLOLEDB which is the provider to access an SQL Server instance.

How to create conditional update trigger in sql server

How to create conditional update trigger in sql server

You cant create a conditional update trigger. Once you create an update trigger it will get called for every update action. However you could write logic inside it to make it do your activity based on your condition using IF condition statement
Say for example if you've table with 6 columns and you want some logic to be implemented on update trigger only if col3 and col5 are participating in update operation you can write trigger like this
CREATE TRIGGER Trg_TableName_Upd
ON TableName
FOR UPDATE
AS
BEGIN
IF UPDATE(Col3) OR UPDATE (Col5)
BEGIN
....your actual logic here
END
END
UPDATE() function will check if column was involved in update operation and returns a boolean result

How to Create a Link to a Discoverer Workbook in Apps11i?-[solved]

I tried to create a link to a disco workbook in apps 11i using metalink document 278095.1. It seems to be working ok for discoverer which is installed on the same machine as the apps11i is on(because when I clicked on the link which I have created in apps11i, I see a default disco4i welcome page which got installed out of the box with apps11i). But we are using discoverer version 10g which is on a different server. Does anyone has ideas on how to create a link for a disco workbook which is on a different server other than apps11i.
Discoverer version is 10g
Apps version is 11.5.10.2
Thanks in advance

hi Rod,
I did as you said and it seems to be connecting to the right server. But I have one more problem. In metalink document it says I have to enter the following in the Parameters text field of Function form in apps:
workbook=<(workbook identifier from step2) &PARAMETERS=param_parameter name One~Parameter One Value*param_parameter name Two~Parameter Two Value*
But I dont understand what should I have in place of param_parameter name One~Parameter One Value. Is it the name of the parameter given in discoverer, if so can you give me an example of how to write it. Because when I typed the name of the parameter like &PARAMETERS=Client Id, where client Id is the name of the parameter, it is giving me the following error
ORA-06502: PL/SQL: numeric or value error
Thanks for your help

Trying to create a linked server to a remote 3rd party server using an AD group

I am the DBA at our organization so I have full authority to all of our local SQL Server databases but we have data in a remote 3rd party SQL Server database that is only read-only. The 3rd party has granted the read only privileges to one of our AD
groups - let's call it mydomain\adgroup1. I would like to create a linked server from one of our local SQL Servers to the remote database. I'm not sure how to do this.
I have set the AD group up as a login and a user in my local database. When I try to create the link, I used the mydomain\adgroup1 as the local login and, since the same credentials exist in the remote server, I checked the impersonate box and click
OK but I get "mydomain\adgroup1 is not a valid login or you do not have permission". Is it possible to create a linked server using an AD group? As of now, we only have the AD group permissions in the remote database. We could probably
request a single SQL Server account to be created on the remote side and we could create the same on our side, but we are trying to keep things as simple and transparent as possible (and we would really like to move more toward AD security and away
from individual users in the db).
Can anyone give me advice on how to get these two SQL Servers linked?

From your description, you likely want to implement Windows authentication for linked server, which requires to implement Kerberos constrained delegation.
I would recommend the following link to get started:
How to Implement Kerberos Constrained Delegation with SQL Server 2008 (https://msdn.microsoft.com/en-us/library/ee191523%28SQL.100%29.aspx?f=255&MSPPError=-2147217396

How To: Create a link to gatewayed content (e.g. in email)

I apologize if this is too basic of a question but I can't find any results after looking for several hours.
I would like to generate a URL in an email that points to the portal and a specific portlet in the portal. The portlet has limited access rights so the URL should cause the portal to go through the login page and then redirect to the portlet. Can anyone point me to the documentation that describes this or give me an example?
Thanks in advance!
Mike

Using the PTARGS might also solve another difficulty I've encountered passing (dynamic) querystring parms to portlets through the gateway. Your example seems to work great for portlets, but now trying to access a Community page containing a portlet to retain branding elements.
For portal pages, should the ObjectID be the pageID (i.e PageID=0 for the default page) or is the ObjectID for a community page some other value (where in PlumDB is this stored) ? I changed the ClassIDView to 514 which should indicate a Community Page but it's still not loading my page. Adding to my confusion, the PTCOMMPAGES table stores the PageID as a negative value.
Here's my example:
http://portalserver/portal/server.pt/gateway/PTARGS_0_0_0_201_0_514/http%3B/portletserver/ApplicationName/default.aspx?querystring=value
Any thoughts?
re: How To: Create a link to gatewayed content (e.g. in email) Posted by Mike Beniston 5/5/05 9:45:40 AM It turned out that I was pretty close.
If anyone else is interested, here is one way that works.
The PTARGS are _0_userid(leave at 0)_objectid(of portlet)_communityID(if any)_0_ClassIDView(43 = view for portlet)
"http://portalserver/portal/server.pt/gateway/PTARGS_0_0_348_208_0_43/http://portletserver/ApplicationName/pagename?querystring arguments.

Linked Server from SQL 2008 to Connect to 2012 read only replica never works

I have two Production Database Servers
1. SQLServer2008 (2 Nodes Cluster)
2. SQLServer2012 with 2 read only replica (3 Nodes Cluster)
I would like to draw a line here, We have routing table and URL working perfectly fine.
We have tested LINKED Server from 2012 Box to production Server by Specifying APPLICATIONINTENT = ReadOnly; it works perfectly fine, the routing is being used.
When we create linked server from SQL Server 2008 Box (Please note we have installed SQL Server 2012 Client tools on this box and Restarted the Servers) using the below script
USE [master]
EXEC master.dbo.sp_dropserver @server=N'AGL1', @droplogins='droplogins'
GO
EXEC master.dbo.sp_addlinkedserver @server = N'AGL1'
,@datasrc='AGL1'
,@provider='SQLNCLI11'
,@provstr='ApplicationIntent=ReadOnly;Database=AdventureWorks2012'
Linked Server is created, Now when I run the Query
exec ('select @@servername') at AGL1
It always brings the Primary READ/WRITE node name only, after lots of research I found that, this linked Server is always using SQL Native Client 10.0 only, even after creating Linked Server using SNC 11, That is the reason it is not going to routing
table. Its always connecting to Primary node.
Below is the way I found it, on 2012 Production Server I executed below Query
SELECT session_id, protocol_type, driver_version =
CASE SUBSTRING(CAST(protocol_version AS BINARY(4)), 1,1)
WHEN 0x70 THEN 'SQL Server 7.0'
WHEN 0x71 THEN 'SQL Server 2000'
WHEN 0x72 THEN 'SQL Server 2005'
WHEN 0x73 THEN 'SQL Server 2008'
ELSE 'SQL Server 2012'
END,client_net_address ,client_tcp_port,local_tcp_port ,T.text
FROM sys.dm_exec_connections
CROSS APPLY sys.dm_exec_sql_text(most_recent_sql_handle) AS T
The help is taken from msdn (Link Provided below) for the above Query
https://msdn.microsoft.com/en-us/library/dd339982.aspx
and I found it always uses SQL Server 2008 SNC.
My Question is, is there a way to force SQL Server to use SQL Server Native Client 11.
Has anyone tried this setup?
Thank you in advance.

Unfortunately no, there is no other way of forcing it without restart. The SQL Server stack has no idea of the existing Native Client as it booted prior its installation. And you cannot force "DLL reload" without proper service restart.
