Installing Oracle 11g Client on Windows 2008 R2 64 bit to use in SSIS

Step 1: Download the 32 Bit and 64 Bit Client from the following location.

Step 2: Install 64Bit Version of the Client first and repeat the same Steps for 32 Bit Client.
Here I am only showing screenshots for 32 Bit installation.Select Custom as shown in the ScreenShot below.

Step 3: Select the language you can to use in the Client tools.

Step 4: Specify the path where you want to Install the Oracle Client. Here I have selected D:\Oracle . You should use same path for 64 Bit Client Installation also. I have shown a summary for 64 Bit Client in Step 7 so its easy to understand on how to configure 64 Bit Client.

Step 5: Select all componenets expect Oracle Scheduler Agent.

Step 6: Port No by default is 2030. Keep it the default one. I selected 2031 because I had installed wrong version of Oracle Client before which used up the Port 2030 :) .

Step 7: Here is the Summary of 64 Bit Client Installation.

Step 8: If you have already installed 64 Bit Client it will give an Error/Warning saying the Service already exist. Just Click Continue because this service is already created by the 64 Bit Client Installation.

Step 9: For Listener just click Perform typical configuration and click Next.

Step 10: Finally it will finish and just Click End/Finish and the Oracle Client is Installed successfully.

Step 11: To complete either the 32-bit or 64-bit Oracle client installation processes make the following registry changes:
1. For both 32-bit and 64-bit installations, open up REGEDIT and make the following registry changes:
OracleOciLib contains the value oci.dll
OracleSqlLib contains the value orasql11.dll (old value is SQLLib80.dll)
OracleXaLib contains the value oraclient11.dll (old value is xa80.dll)
2. For 64-bit installations:
OracleOciLib contains the value oci.dll
OracleSqlLib contains the value orasql11.dll (old value is SQLLib80.dll)
OracleXaLib contains the value oraclient11.dll (old value is xa80.dll)

Step 12: Configure the Oracle clients (both 32 and 64 bits) by editing  the files tnsnames.ora and sqlnet.ora

Both files should be placed in the following Folders

Tnsnames.ora file should contain similar connection string as follow
AB10P =
      (ADDRESS = (PROTOCOL = TCP)(HOST = = 1527))

Step 13: Use the "Oracle provider for OLE DB" from SSIS, don't use the "Microsoft Provider for Oracle" because a 64 bit version of it does not exist.

Sample Connectionstring : 
Provider=OraOLEDB.Oracle;Password=testPassword;Persist Security Info=True;User ID=User1;Data Source=AB10P
Tableprefix: Test1"."
Provider: Oracle Provider for  OLE DB


  1. Hi,

    I have installed 32 client as per your instructions. While installing 64 bit client I am getting an error at "Perform Prerequisite checks":

    This is a prerequisite condition to test whether the system has a certified architecture. (more details)
    Expected Value
     : 64-bit
    Actual Value
     : 32-bit

    I have used software location as C:\oracle\product\11.2.0\client_64. for 32 bit it was C:\oracle\product\11.2.0\client_32.
    Port for 32 bit 2030, for 64 bit 2031.

    Please advise.


    1. It is a bug in the Oracle installation.
      If you want to install both the should install 64 Bit Client first.
      So what you need to do is
      1. Uninstall 32 bit Client.
      2. Install 64 Bit Client.
      3. Install 32 Bit Client.

  2. Somebody necessarily help to make severely posts I might state. This is the first time I frequented your website page and to this point? I surprised with the research you made to create this particular post extraordinary. Well done admin..
