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.

I have a similar scenario with you. My dimensions deploy on different SQL Server and It was not update so far.

Hi Silna it's a useful guide and resolve my problem, thanks.

@Winnie you can following that link to check your configure files, before process Dimension and Cube please take care of their proactive cache property (MOLAP or ROLAP default was disabled!). And I think you should also check the "Update the cache periodically" option.
