Analysis :: Change Dimension Storage Type As Real-time Rolap But Error Occurs?
Jul 7, 2015
I Create a measure group and two dimensions using [AdventureWorksDW2012], I try to change one dimension's storage mode with setting property proactive caching as Real-Time ROlap. There is no any warning message when deploying and processing, but error occurs when I query in sql server analysis services, see below for the error messages and the screen capture.
Error occurred retrieving child nodes: the current operation was cancelled because another operation in the transaction failed.

I have SSAS 2008 Enterprise sp2 (not R2) running on a production server. One of the dimensions is defined as real-time Rolap - set to clear the cache whenever the table changes.
I placed triggers on that table to be sure, so I know no changes occur on that table sometimes for 10 or 15 minutes at a time - and yet I get 100's of change notifications (I noticed them on a profiler session). It seems as though the notifications come as often as the dimension gets queried.
I think this is causing one of my longer running queries to fail because of locking issues. I assume this is because the queries are getting killed when they're in middle of using an outdated cache.
The strange thing is that I cannot reproduce this on the dev servers. The main difference between the dev and production servers is that the production servers are behinfd a cluster. I don't know if that could make any difference.
I really need to know why I'm getting so many notifications.

I am trying to create a ROLAP cube with 'Enable real-time updates' .
When I go to process the cube it fails stating, Creating indexes for Aggregation XXXX
CANNOT enable real time updates on this partition without indexed views: <date>
Im running SQL Sever 2000 Developer Edition - SP4 on Windows Server 2003
My cube don't use DCount measures ,only simple calculation

<SQL Server 2008 R2>
I created a Time table using BIS. I found that the default naming of time members is too long and redundant.
For example, the wizard generated "Fiscal Calendar 2015", "Fiscal Quarter 1, 2015", etc. However, shorter expression like "FY2015", "FQ1 2015", etc would be enough for me.
Is it possible to change the default naming rule, or does SSAS works correctly if I update the Time table values using SQL?

I have 2 dimensions that pull their Facility Name from the same Location Dimension. The business users want to change Facility Name in the Material Facilities dimension to “Material Facility Name”, but keep Facilities dimension attribute the same. What is a good way to go about completing this task.

I have a monthly time period dimension representing average number of students for each month. At the yearly aggregate level I don't want it to sum up the avg number of students from every month because that number is incorrect. I would like it to use the number of students from the most recent month as a roll up. Is that possible to configure in SSAS?

Hi!
Need some help building a query that does the following :
I have 2 Time Dimensions ; Time (Transdate) and ClosedDate (ClosedDate)
In my report/query, if [Time].CurrentMember = [Time].[YMD].[YMD].[2006].[200610].[20061031] I want to FILTER out all ClosedDate < [ClosedDate].[YMD].[YMD].[2006].[200610].[20061031]
Both Time Dimensions are Year -> Month -> Day and have the same Members.
I have every option available, using calculated Members and/or Measures to do this.
The report I'm creating is Aging of Receivables : Balance / 30 days / 60 days / etc.. But for the Aging, I need to filter like explained above.
Appreciate all help!
Regards,
Stian Bakke

I'm having trouble with cube processing. While processing a code I'm getting a "Invalid column name MessageType" error.
I unfolded the cube, then I opened "measure groups", my failing dimension (ServiceRequestDim) and the partition.
In the partition I opened the "Source" attribute so it now includes my column which was missing. But it didn't solve the issue.
If I get the query used during the process I'm getting this :
SELECT
DISTINCT
[ServiceRequestDim].[MessageType] AS [ServiceRequestDimMessageType0_0]
FROM
(
Select IsNull(IsDeleted, 0) as IsDeleted, [ServiceRequestDimKey], IsNull([Status_ServiceRequestStatusId], 0) as [Status_ServiceRequestStatusId],[Status],IsNull([TemplateId_ServiceRequestTemplateId], 0) as
[Code] ....
In the nested query which defines ServiceRequestDim the messagetype attribute is still missing. In my source datamart the ServiceRequestDim has the "MessageType" column.
So the question is where do I change the nested request that the dim process use to reflect the actual columns in my datamart .

I have an identical SQL database on two machines (my machine and a webserver) that links to a database on a third server (S3). When I executea stored procedure on my machine that accesses a database on S3, italways runs without a problem. However, when I run the same storedprocedure on the webserver (via Query Analyzer on my machine, connectedto the webserver), the stored procedure runs without a problem forabout ten minutes, and then I suddenly receive the error "Login failedfor user '(null)'. Reason: Not associated with a trusted SQL Serverconnection.". If I then connect remotely to the webserver via RemoteDesktop Connection and run the stored procedure there it works, andthen I can run it again on the webserver via Query Analyzer on mymachine, but the same problem will occur again after about ten minutes.The only difference between my machine and the webserver is that thewebserver is running Windows Server 2003, whereas my machine runsWindows XP. All settings in SQL on the two machines are identical, so Iwould love to know if anyone has a possible solution to this seeminglyrandom problem.

I have a question about the storage design wizard in the analysis manager.
We are working with different seasons in our reports and every week we update the data of the seasons in our cubes. But as seasons end, and at some point the data for old seasons doesn't change anymore, I don't think it is necessary to update every season every week (which we now still do now for seasons in, for example, 2004). It's a waste of time. So my question now is. How can I storage the data of previous seasons (and work with them in the report) and still be able to update the current season? Can I use the storage design for this??

Hi all.
I have posted this question in another forum but no one has so far been able to provide a solution to the problem. Since I know Database Journal always has very informative and enlightening posts, I figured I'd post the question here in hopes that some guru can provide an answer.
If you're running SQL 2000 and have any jobs that have been executed, you could perform a query as such:
select last_run_time from msdb.dbo.sysjobsteps
and receive returned values that contain the last time a job was executed "stored in integer datatype" columns. See ->
sp_help sysjobsteps.
In SQL 2005 I believe the concept is the same. I think the intent of Microsoft had it mind for doing this was to store the date separate from the time values which won't work using the datetime datatype and I have read this in documentation in the past.
The challenge is to convert that data into a humanly legible 12 or 24 hour time format like 11:00 AM or 02:45:39.
Does anyone have any suggestions or clues to assist in resolving this problem??? :(
Thanks.

I need to change these files to D drive.When i go to the database properties
and try to change the location it does not allow me.It has given me a message(The database physical file cannot be changed once it is created).
I can drop the table and recreate it from a BackUp but is there a better way

Many dimensions don't have unique members. Instead, the dimension source data has duplicates at the leaf level: it's left up to SSAS to aggregate up to the actual leaf level used in hierarchies.
Every cube I've worked on in the past, a dimension is clearly defined in the source data, with uniqueness already present there: we don't make a dimension out of duplicated, sort of facty data. This kind of design seems as weird to me as an unnormalised SQL database.
Here's an example to illustrate what I mean; I'll use that Adventureworks database.
We have a Geography dimension with a Geography hierarchy. Levels go like this from top to bottom:
Country
State-Province
City
Postcode
The Geography dimension has a key attribute called Geography Key. It's there in the cube design as a dimension attribute, but it's not in any of the hierarchies, so I can't query it in MDX. But that's fine: it has the same cardinality as the lowest level (Postal Code), because the dimension has some kind of normal design.
In the cube I'm dealing with, it's all messed up. Using the AdventureWorks example above as a parallel, someone made a Geography dimension with source data keyed on [PostalCode, ExactAddress], but only wanted the dimension granularity to be PostalCode.
This makes it very hard to debug why the data in this dimension is incorrect. I can't match up the dimension members in the cube to the source data, because the dimension doesn't actually go down to the real leaf level!
So I have a dimension attribute called ExactAddressKey, but I can't query on it in MDX, because it's not part of any dimension hierarchy. Unfortunately changing any part of this cube design is not possible, so I can't even experiment with settings and see what happens.
How I could get to the leaf level of the data imported? Something like
Geography.Geography.TheInvisibleLeafLevel.Members.Properties('Key')
Or does this kind of dimension design result in SSAS discarding all the data that's more granular than the most granular attribute defined in any hierarchy - so that the data actually isn't there to be queried?

I 've read that there is a workaround for this issue by customizing errors at processing time but I am not glad to have to ignore errors, also the cube process is scheduled so ignore errors is not a choice at least a good one.
This is part of my cube where the error is thrown.
DimTime
PK (int)MyMonth (int, Example = 201501, 201502, 201503, etc.) Another Columns
FactBudget
PK (int)Month (int, Example = 201501, 201502, 201503, etc.)
I set the relation between DimTime and FactBudget doing DimTime MyMonth as Primary Key and FactBudget Month as Foreign Key.
The cube built without problem, when processing the errror: The attribute key cannot be found when processingwas thrown.
It was thrown due to FactBudget has some Month values (201510, 201511, 201512 in example) which DimTime don't, so the integrity is broken.
My actual question: is there a way or pattern to redesign this DWH to correctly deploy and process?

I currently have an application which retrieves stats from a SQL database that are updated throughout the day. My application updates every 3 seconds to retrieve these stats but I found that it's quite expensive to the server's CPU when there are several clients running my application. Are there any other methods for extracting the data that won't require so much CPU. The fact that the database is being hit so much isn't good either. I have already written a webservice hoping that this would improve things but I'm not sure it has.

We are using SQL 7 at 2 different locations, on 2 different Domains that are connected via a T1 line.
We need to have our 2 SQL servers be identical at all times, meaning when a change is made on one server, it is immediately replicated to the other. The problem is that both servers are always being used, so there is no primary/backup server scenario.
Does anyone know if there is a third party software available, or if this is even possible to do, given the fact that the databases are always open ?
Thanks.

i have 2 DB in 2 different servers.
db1 and db2
db1 gets 150k records every hour. db2 is like the backup of db1. db2 is used to retrieve records to create reports using reporting services.
what is the best way to synchronize db2 with db1?
is it to create a dts package and set up a job that runs every hour?
off topic question.
what kind of language does reporting services use to create the reports?
