Error Connecting to Oracle database when installing IBM

Asked By 0 points N/A Posted on -


While I was trying to connect to Oracle Database on Windows Server 2008 this message box appeared. I have checked my Internet connection and it works just fine. I rebooted the PC hoping that I will connect but it didn’t work. Can anyone help me please to fix this error ? Why I cannot connect ?

Thank you !

Could not connect to Oracle database (TCLS17) . Reason: Unknown error: Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.

Error Connecting to Oracle database when installing IBM


Hi Luis,

1) The reason for such a problem is  System Architect is a 32-bit application and requires that the 32-bit Oracle client be installed.

2) But you have only installed the 64-bit Oracle client. You should check the requirements for IBM Rational System Architect to communicate with Oracle on a Windows Server 2003 64-bit operating system.

3) For the solution of the problem you can Install the 32-bit Oracle client. Once the 32-bit Oracle provider has been installed on the 64-bit operating system, you will be able to connect to the Oracle database using System Architect, System Architect Encyclopedia Manager for Oracle & System Architect Catalog Manager.

Hope this will help you.
