When running your OCI cgi program from the unix shell are you using the same user that apache is running as? e.g. nobody?

It could be that when you are testing it, you have a properly defined oracle environment (ORACLE_HOME, ORACLE_SID etc), but not when the cgi script is running under the user who runs apache or the user who is running apache does not have access to directories needed etc.
