Hi all
We have been experiencing problems in recent times with our daily Lite Optimise process taking around 40 minutes to complete. Frequently, we have users trying to write back to the model during this time which, of course, fails. Therefore, we are very eager to reduce the amount of time the model is out of planning mode. We are also an international organisation so there is no 'quiet period'.
One very interesting article I have stumbled across suggests starting the 'Create Statistics' step then 3 seconds afterwards put the model back into planning mode.
Step "'DB Statistics Refresh" of /CPMB/LIGHT_OPTIMIZE is very slow and fails after 2 hours
In our case, the roll-up and compress only takes 7 minutes whereas the 'Create Statistics' step takes a whopping 33 minutes.
Does anyone have an opinion on this ? Would the statistics still update if the model was in planning mode 3 seconds afterwards ?
What about the statistics, is there any way of speeding up this process ?
Any pointers would be very much appreciated.
