working on Windows Server 2008R2 64-bit, installing ruby 1.8.7, ruby-oci8 ran into the following error, after requiring 'oci8' :
LoadError 193: %1 is not a valid Win32 application
On this machine a 64bit version of Oracle was installed. So the OCI.dll was a 64-bit version. The fix seemed easy: copy a 32-bit version of the OCI.dll.
But I had to copy (from another 32-bit machine)
- OCI.dll (32-bit)
- ... and ORAOCIEI10.dll
to my ruby\bin folder, and then everything worked.
Copying just the OCI.dll and MSVCR71.dll gave the puzzling error
OCIError: OCI library initialization error.
