congrats on listing the version of the database server software as 8i. is that:
8.1.5 8.1.6 8.1.7
version of the Oracle client software?
e.g. 10.2.0.1 client
Operating system of the client and server?
If you upgrade both client and server to 10.2.0.4 this problem will (likely) magically go away and you won't have to delve any further, like into a non-accessible Metalink Oracle Support site.
