OBIEE 11G and tnsnames.ora

Where do I put tnsnames.ora in OBIEE 11G?

In versions of OBIEE prior to 11g you would use the tnsnames of the Oracle client and the tnsnames would be found in the network/admin directory.

In OBIEE 11G you can place your tnsnames file directly into the middleware_home/Oracle_BI1/network/admin directory.

Works for me.

Update:

You can connect WITHOUT a tnsnames file.

OBIEE 12c uses a different directory
