Anjo, from what I can see, you're not connecting to an instance using Oracle*Net as in the DBI/DBD world, you're "attaching" to it. That makes me think that you're using OCI to connect as SYSDBA, which means that you have written a new module which has to be integrated in perl. As perl executables are normally owned by root and their protection mode usually doesn't include setgid bit, they cannot connect to an instance, unless the invoker is not a member of a DBA group. That means that you're writing a package specifically targeting us DBAs. Goody, goody, me likes that!
