Hi,

What is your Oracle client version? It should be 32bit. I think for Oracle 12 the driver is JDBC7. Please check.

Hi,

I'm pretty certain Oracle 12 isn't supported for use as a content store with Cognos 10.1.1. If memory serves, only Oracle 10g and 11g were supported? Oracle 12c support wasn't added until the 10.2.1 release of Cognos.

You're going to need to upgrade to a supported version of Cognos BI or revert back to an earlier version of Oracle.

Cheers!

MF.
