Can not get any update after did dimension proactive caching setting.

Hi everyone,

Recently, I was blocked by the dimension proactive caching, following is what I set, but seem that I didn't get any update, could you please help me take a look at, and check which step I missed?

The AS database is tha sample of Microsoft(AdventureWorksDW), its datasource is the atventureworksDW on the same machine

1. process AS database;

2. right click the dimension "Date" and get the properties;

3. click the "Proactive Caching" and click the "options.." on that page;

4. set "Storage Options" dialog

   Storage Mode: MOLAP

 1). General tab:

      a. Caching Settings:

          check "update the cache when data changes"

          Silence interval: 10 seconds

          Silence override interval: 10 minutes

      b. check "Bring online imediately"

 2) Notifications

     a. Check "Scheduled polling"

    polling interval: 1 minutes

    polling query: SELECT COUNT(*) AS TotalCount from DimTime

5. insert query "insert into DimTime("TimeKey","EnglishDayNameOfWeek") values(1180,'dimtest')" to relation database;

6. use following MDX  query after I did step5 1 minutes later

with member x as [Date].[Day Name].allmembers.count
select x on 0
from [Adventure Works]

7. I didn't see any changes with this query, I'm sure I have inserted this the data.

Thanks

Winnie
