Best to start your own thread with your own information. The more detail you can provide, the better. But as is already abundantly clear even in this archeaological thread, ora-0600 means "open an SR with Oracle support."
And, no, this forum is NOT where you do that. This forum is a community of peer volunteers. It is provided by Oracle as a convenience to the community, but is NOT the official support channel and is not manned by support technicians.
