event="10513 trace name context forever, level 2" is not disabling SMON transaction recovery
We are having shutdown immediate problem after cloning, as soon as duplicate DB completes we try to shutdown the database and it hangs. We could review it and found that there were 12 Dead transactions and 67000 blocks required to be rolled back. We were doubting it so we did set this event at cloning time.
Effectively this event should disable these dead transaction recovery but it does not take effect. This time we let the shutdown coutinue for 4 hours before the shutdown abort. The number of blocks changed from 67000 to 10000. During this 4 hour of time smon was taking 100% cpu. Note -
