Trouble connecting to 64 bit oracle client from 32 bit environment

Hi,
I have an application which connects to Oracle and an external 3ed party application via a set of APIs. We are now facing the issue while migrating our server from 2003 to 2008.
The 2003 server was configured for 32 bit and had 32 bit Oralce installed on it. It was able to connect to both Oracle and the 3ed party API in this configuration
In our New 2008 server we have installed a 64 bit Oracle however the 3ed party API is using is 32 bit. Once we use the 64 bit app poll we were able to connect to the Oracle, but the API connection fails. When we enable the 32 bit in APP Pool, wer cant connect to the Oracle client.
Could you please suggest a possible soultion for this problem?
PS:
We have tried placing the 32 bit Oracle.Data.Client DLL in the Bin folder and refered it in our project ( to avoid refering the 64 bit DLL from GAC) but this method didint work out.
We have alos tried placing Oracle Data Access Componets DLLs in Our bin as explianed in the following blog post
http://researchaholic.com/2011/10/21/connect-from-net-to-oracle-without-installing-the-oracle-client/
This also did not help us connect to the Oracle client.
Right now we have configured our new 2008 server with 64 bit oralcle client and enabled 32 bit support from APP pool.
Thanks

You can't use 64 bit client on 32 bit machine.
You can use 32 bit client on 64 bit machine via syswow64, but not the other way around.
If you compile your app with AnyCPU compile target though, it will automatically run as 32 bit on 32 bit OS, and 64 bit on 64 bit OS.

Oracle Client 64-bit and Oracle Client 32-bit on the same server

Hi,
I have a Windows 2008 server 64-bit with Oracle Client 64-bit and Oracle Client 32-bit installed on different directories (D:\Oracle and D:\Oracle32)
Is it possible to define for certain applications to use the TNSNAMES entry from the 64-bit Oracle Client
and for other applications to use the TNSNAMES entry from the 32-bit Oracle Client
Once I installed the Oracle Client 32-bit (Oracle Client 64-bit version was already installed) and restarted the server I performed a TNSPING and it defaulted to the Oracle Client 32-bit installation path
Thanks,
Barry

Hello,
When you install a new client on a server, it will update the PATH variable, and add the ORACLE_HOME\bin path to it, at the first place. That explains why the tnsping use the last installed ORACLE_HOME.
What you can do if you want only to change the default path to the tnsnames is to set the environment variable TNS_ADMIN to the path where the tnsnames you want to use is located. You can modify this variable in your application if you want to use another tnsnames.
If you want switch from 32 bits to 64 bits client, then you have to modify the PATH variable.
Hope this will help.
Best regards,
Sylvie

SSIS used to integrate SQ Server and Oracle - Is it necessary both 32 and 64 bits Oracle Clients installed?

Hi all,
SQL Server 2012 EE 64 bits (SOURCE)
Oracle 12c 64 bits (DESTINATION)
To make my solution - integrate SQL Server with Oracle - work, i had to install both 32 and 64 bits of the Oracle 12c Client. After that, i had to change the properties of my SSIS package to run on 32 bits only (properties > Debugging >
Run64BitRuntime set to FALSE). Before i made this change, the execution of my package was failing, but after setting Run64BitRuntime to false, the package ran successfully. Why is that?
I am thinking of unistalling the 64 bits ORacle Client from my Windows Server, but i fear that if i uninstall, my package stop working.
Any suggestions/corrections will be most appreciated.
Thanks in advance
OBS1: I am using ODBC as the source and destination tasks.

Hi FabrícioPJ,
The 32-bit and 64-bit versions of a provider have the same ID. Therefore, the SSIS runtime will select the appropriate version of the provider to use. 32-bit SSIS Designer always requires and uses the 32-bit version of a provider at design time. However
when running the package in 64-bit mode that the Run64BitRuntime project property is True, it automatically switches to the 64-bit version of the provider. When it couldn’t find 64-bit version of the provider, the package would be failed. For more details,
please see:
http://dougbert.com/blog/post/64-bit-considerations-for-sql-server-integration-services-final.aspx
So in your scenario, it seems that there is not a 64 bit provider for Oracle in your environment, so the issue occurs. Please make sure you have installed the correct 64-bit version of the Oracle provider.

You do not need to do anything in VS. You do need to configure both tnsnames.ora files, because the drivers do not share any data.

Hi,
Based on the error message, we should confirm whether Oracle client tool has been installed on the Report Server at the beginning. If the Report Server installed is 64-bit, we should also install a 64-bit Oracle client tool on the Report Server. Besides, we
can also try to bypass tnsnames.ora file when connecting to Oracle by specifying all the information in the data source instead of using the TNS alias to connect
to the Oracle database. Please see the sample below:
Data Source=(DESCRIPTION=(CID=GTU_APP)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST= server01.mydomain.com)(PORT=1521)))(CONNECT_DATA=(SID=OracleDB)(SERVER=DEDICATED)));

Can we install oracle client 32 bit on Linux 64 bit

Can we install the 32 bit applications like the oracle client on to a database server 64 bit and linux os 64 bit ?

This question is two parts which I paraphrase as per my understanding; please correct me if I'm wrong:
1) Can you install 32-bit applications (like the oracle client) on to a 64-bit Linux OS?
Quick and correct answer is: Yes. Most distributions will include 32-bit libraries along with 64-bit libraries for just this purpose.
2) Can a 32-bit Oracle Client "connect" to a 64-bit Oracle Database server?
Yes.
So ultimately, you could install 64-bit Oracle Database on a 64-bit Linux OS, and then continue by installing the 32-bit Oracle Client on the same host (although I see no real reason for this), and then finally use the 32-bit Oracle Client to connect to the 64-bit instance running on the same host.
Hope this is helpful!

Install 16 bit Oracle client on Win 2003 server

Hello,
Is it possible to install Oracle SQL* Net 2.3(16 bit) Client on Windows 2003 server. If it is then could someone give me links from where I could get more information on this (like the steps to install 16 bit Oracle client on Win 2003).
Thanks.

the 16-bit applications are not supported by Windows 2003 server x64 edition.
http://support.microsoft.com/?kbid=896458&SD=tech
I have never tried to use 16-bit SQLNet client on Windows 2003 x86. I'm pretty sure that this combination will not be supported by Oracle , athough it could work.
As far as I remember the 2.3 client was shipped with the Oracle 7.3.
here is the desupport notice for Oracle 7

Oracle Client 32 bit installation on Exadata Machine

Hi,
We are starting our migration to exadata next month.
One of the issues we have is regarding to our Informatica ETL tool . Our application is licence to 32 bit.
The database repository of this tool is currently running on linux redhat 5.5 64 bit with 11203 rdbms version.
We had to install oracle client 32 bit software , in order to allow the application to connect to the database.
Is it possible to install oracle client 32 bit on exdata ? If not what would you suggest ?
Best Regards

I can't speak for Informatica, but it should be able to connect to the database over the network, so the database server OS wouldn't matter in that case. That is, if Informatica runs on a different Linux machine that runs 32-bit Linux, it can connect over the network to the Exadata database server node. If Informatica requires to run on the database server directly, you'd have to ask them how they can support 64-bit Linux (or you may have to modify or add to your license).

FDM 11.1.2.3 issue (32 or 64 Bit Oracle Client) ?

Hi All,
               I have installed FDM 11.1.2.3 under Windows 2008 server using Oracle 11g Database. Its configuration was sucessfull, but I'm not getting create an app and having "connection database" errors. In a previous version (11.1.2.2.) was stated that FDM should use 32-bit Oracle client installed. But at 11.1.2.3 documentation I did not found anything related to this and installed it using 64-Bit Oracle Client.
              Does someone could tell me if FDM 11.1.2.3 requires 32-bit Oracle client installed ?
Thanks

It does still use the 32 bit Oracle CLient.
You would need to test the connection with a 32 bit UDL file (.udl32) and use the following command to test:
1. Create a file to test the 32-bit OLE DB Provider. (Create a new empty file in a easily accessible location with the extension UDL32) a. Launch a command prompt. b. Start notepad and pass in the name of the new file. c:\>start notepad c:\testconn.udl32 c. When prompted to create the file, choose yes then close notepad. 2. Test the 32-bit OLE DB data source using the new file and the following command. a. Launch a command prompt. b. Execute the following command.    c:\WINDOWS\SysWOW64\Rundll32.exe "c:\Program Files (x86)\Common Files\System\Ole DB\oledb32.dll",OpenDSLFile c:\testconn.udl32 - Note, make sure the command line is something appropriate for your Windows Installation. d. Click the Provider Tab, select OLEDB provider you're trying to test (Ie, Oracle Provider for OLE DB) - Note, ODBC connections can also be tested by selecting Microsoft OLEDB Provider for ODBC Drivers. e. Click the Connection Tab. Enter a valid connect string for Data Source. Enter a valid user and password for
he database. f. Click the Test Connection button.

Windows 8 operating system + applications requiring 32-bit oracle client

Hi,
We are trying to install oracle 32 bit client on Windows 8 opertaing system
11.2.0.1
Have done so successfully on Windows 7 but Windows 8 says doesn't meet minimum environemnet requirements.
We have a 32-bit appliactuion which requires oracle client
When we tried the 64-bit oracle client on the Windows 7 onne, application didn't work so henec the 32-bit oracle client which allowed the application ro work O.K.
Problem is we need to have this application working in Windows 8 environment.
Any thoughts if can use oracle 32 bit client on Windows and if so where I can download from?
Thanks

Regardless of whether test or production machine, why would you choose an unsupported combination ? Which exact version of Win 8 ?

Problem with Oracle Client(64 bit) install on Windows 7

Hi,
I am trying to install Oracle Client 64 bit (win64_11gR2_client) on my laptop and its giving me all the pre requisite failed for "Physical Memory, Free Space, Architecture and Enviornment variable: Path". So i need to exit that setup.
I have enough space almost 130 GB free on my laptop. Also, i cleared temp data. Then increased physical memory to 4096 MB but still facing the same error and not able to install the Oracle Client on my laptop.
Please assist as soon as possible.

Install oracle client 32 bits on 64 bits windows

We need to intall Oracle driver for OLEDB on a SQL server box.
The SQL server is windows 2008 R2 and SQL server 2008 R2, 64 bits.
But because we have some SSIS packages that need to run in 32 bits,(for example the source file is the Excel), so we are installing oracle client 32 bits instead of 64 bits on the windows box which is 64 bits.
Anyone knows if this will work?
Thanks

I think it should work. I have a server Win 2008 x64 which runs 32 bit 11g client and we haven't had an issue. I had the same situation as you are in which required me to install 32bit client on x64 server. if you have a test server I would try this on the test server identical to production to make sure that you won't see any hick ups in your production environment. hope this helps.

Installation of Oracle Client 32 bit on Windows 64 bit

Hi ,
I'm trying to install the 32 bit Oracle client (release 11.2.0) on a Windows server with 64 bit (Microsoft Windows Server 2008 R2 Standard, Service Pack 1).
It's my understanding that this is supported and should work. However, the 64 bit Oracle client (release 11.2.0) is already installed on the server.
We need the 32 bit client since an older application requires this.
The GUI for the install of the client starts fine - but when the step "Finish installation" the GUI suddenly disappeares. The logfile of the installation ends
with
INFO: Setting the value for INSTALL_TYPE variable
INFO: Variable "INSTALL_TYPE" wird auf "InstantClient" festgelegt. Der Wert wurde von der Befehlszeile empfangen.
INFO: adding the variable oracle_install_NoMigration to command line args table

INFO: Creating & Initializing the Session Interface Manager
INFO: Calling OiicInstallAPISession's prepareForInstallOperations

I'm executing the installation as a local admin - I've tried the installation with setting the compatibility mode to Windows 2000. No success at all :-(
Did I get it wrong that ths 32 bit client is certified with this windows version? Does anybody have experience with the same situation?
Any help will be appreciated!
