Help me! AWM "maintain cube ... " performance: too slow with a small cube

Question

Hi all,
I have 3 dimensions: TIMES, PRODUCTS, STORES
The hierarchy of TIMES, is in the order: year, quarter, month, week, day
The hierarchy of Products is in the order: sector, family, sub-family, product
The hierarchy of STORES is in the order: area, department, store
each hierarchy is mapped with a data set and the size is
730 lines (days) for the TIMES dimension
282 lines (products) for the PRODUCTS dimension
237 lines (stores) for the STORES dimension
With these dimensions, I create a cube and 2 measures: QUANTITY, BENEFIT
My measures used all 3 dimensions : TIMES, PRODUCTS, STORES.
I mapped in the end my cube with a dataset contains: store, day, product, quantity, benefit
This data set has 3921 lines.
I chosed the rule to aggregate all dimensions is SUM.
So when I do "maintain cube...", AWM takes much time to do it! (approximately 2h to maintain my cube)
Some one knows why it's long?
How can I do to accelerate it?
Due I modify the parameters in AWM or in my cube?
Thanks in advance!

Answer 1

thanks all for your reply!
I done maintain cube already in following your advice. I increased the rollback and tmp space and changed "NUMBER to DECIMAL" as type of data of cube.
But I have other question. I hope you can help me!
1. What's the effect of the option "Choose the regions of the cube to be presummarized and stored in the analytic workspace" in the table "Summarize To" when you create a cube? If I check this option for all hierarchy level, the next time, when I do the request,
the time of calcul will be optimize so fastest?
(I check this option in creating my cube but when I make a request for level of a particular hierarchy, it's so long to have the result. I use a software this can connect and do request from Oracle Olap DataBase.)
2. I done maintain cube last week. Today I created a new cube and added more data set. But I cant maintain cube again. This is the message error. Can you explain to me why?
( I increase already the rollback and tmp space. To know how and what I done, view this thread please!
