ORA-03113 means your session and the server process have stopped talking.
This shouldn't happen in your situation. Of course if you have further
complications (like it's not a table but a complex view, or there's a VPD
function or....) then there maybe a specifc bug/issue that you hit. In
either case the trace files mentioned earlier should give you more info
