performance issue after upgrade 18.104.22.168 to 10.2.0.4
Posted on 2011-02-10
There was NO CHANGE in performance on TEST, good or bad, until...
ATP ran for 1hr and 7min, Saturday night at 6:07PM then collided with the 7:07PM reload and crashed until I reset it this morning.
Up to that time the RUP7 and Oracle ATP
patches seem to have no effect on the
reload timing. The only thing that produced any change (for the better) was AMM configuration.
The net effect is that, when DEV is down, TEST is still running slower (and there are no increases in products, warehouses or orders) than prior to the UG.
Meanwhile, PROD has grow to 30min 30sec on average, with better performance on Sunday.
One more observation I have to offer, the WORSE time recorded on PROD was at 6:07PM on Saturday (Hummmmm, the same time TEST had it's worse time) with a time of 42 minutes to complete the reload.
Is there some network activity that is causing the data transfer between DB_Server and App_Server to degrade at certain times?
Are their any other DB tuning parameters or kernel parameters that can be considered for 11gR2?
