oracle connection configuration

[leonardosampaio]

Hello Friends,
in some application here, theres an oracle connection using ocilogon() function. I have just upgraded xampp to newest version (1.8.1) and now i get this error: "Fatal error: Call to undefined function OCILOGON() in..."
I searched for a solution and tried to uncomment some oci8.dll's and stuff, even tried changing ocilogon to oci_connect but still got the same error.

I think this is simple to solve, but no idea how to do it.
How to replace this function and/or make it run ok?
