DBDriver failed to load dbd_oci.dll (not a valid Win32) (WIS 10901)

Dear Gurus,

I am trying to access universe through WEB INTELLIGENCE but the connection is giving me following error

DBDriver failed to load dbd_oci.dll (not a valid Win32) (WIS 10901)

"A database error occured. The database error text is: (CS) "DBDriver failed to load : C:\Program Files (x86)\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\dbd_oci.dll (%1 is not a valid Win32 application.

)" . (WIS 10901)"

As per the documentation , web intelligence uses BO server connection while tools like Designer uses local connection.

I am working on BO server only , both tool should use the same connection.

OS : MS WIndows 2003 R2 64 Bit

BO Server : bosmserv

Oracle : Oracle 10.2.0.4 , client 10.2.0.4

Connection to database schema is working through universe designer and System DSN but not through Web Intelligence.

In addition JDBC connection to the same databse schema is giving me following error CS: Java Class not found in classpath : oracle.jdbc.OracleDriver

Please suggest.

Note : I have already applied following note :

1378354 - If we create the webi document, the error occured "The specified module could not bi found(dbd_oci.dll), (WIS 10901)"

Regards

Arif
