Dear Jmodic

A very big thank you for very detailed answer. I am running on 8.0.5.2. I do have the following questions:

1) The following recommendation to adjust in my init.ora

event="10231 trace name context forever, level 10"

Please explain what the number 10231 and level 10 mean, and is this what we have to put in the init.ora regardless of corrupted block?
