when we are trying to update tables from application (VB source code for particular block is attached) randomly, it is throwing ORA-3113 channel. This is not happening for a particular table or at a particular time. I have looked into alert logs and traces (attached here), but hardly I found. This is not happening when we are trying to do this from TOAD. But even there also after half-an-hour it throws the same. could you help me to fix this problem?
