CUBE WRITE BACK in SQL SERVER 2008 R2
Did anybody get the SSAS write back functionality to work against a decent sized datawarehouse? I'm not asking about a little demo but a significant sized footprint e.g. 14M Rows measures, 6-8 wired Dimensions with 8-10 attributes each.
I setup a test server using a Dell XEON ( 2x4core) with 48 GB RAM hardware and the latest Sql Server 2008 R2 release. I used the What-If scenario in Excel 2010 and modified a higher level, hoping SSAS would push the values down.
After about 15 minutes and after having used 48 GB memory (on average 5% CPU) Excel throw an error - short on memory - and stopped the action.
I found the same behavior in Sql server 2005 and 2008 and was hoping this would work now but apparently not so.
Here are my questions:
- Is anybody using this at all?
- how can one calculated (roughtly) how much memory is requiered?
- is there any paper that describes best practise?
Thanks for any help in advance,
Dirk
