Analysis :: SSAS - Dimension Processing Failing Due To BitLocker Encryption
May 8, 2015
I'm facing an issue while processing OLAP. I have enabled BitLocker for dirve encryption and OLAP services uses this drive for db storage. OLAP is executing though SSIS package and I'm getting below error in Package. When debugging the script, it says Drive is encrypted using BitLocker.
My client requires TDE for all databases, for OLAP we decided to use BitLocker: [URL] ....
SQL server is installed on C Drive & D Drive is the storage location for OLAP DB. When locking D Drive, OLAP processing failed. When I tried to restart SQL Server Analysis service in Services.msc it is not starting. Service restarted only when D Drive is unlocked. Is there any way we can process OLAP even when the drive is locked?
Error message is given below:
"The following system error occurred: This drive is locked by BitLocker Drive Encryption. You must unlock this drive from Control Panel. "
I am facing issue with partition processing. I am having a SSAS cube which is having 5 partitions. These partitions are processed through a sql server job using SSIS packages. In packages I used SSAS process task to do this.Now problem is, job is running successfully and showing that the step which is having partition process also fine.But data is not updating in the partition. While checking the partition properties, it is not updated with recent date and time.
When I try to manually process the partition, it is getting succeeded and recent data is getting reflected with recent date and time.Package configuration is done in job itself.
I'm getting this error during processing one dimension.OLE DB error: OLE DB or ODBC error: SQL Server blocked access to STATEMENT 'OpenRowset/ OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online.; 42000.my dimension contains member from two datasource table.
and in another dimension i get error;Errors in the high-level relational engine. The 'dbo_vicidial_Users' table that is required for a join cannot be reached based on the relationships in the data source view.Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Staging User', Name of 'DimUsers' was being processed.
how to move the dimension attributes from currency to geography and vice versa(i.e need to change their positions) in SQL Server 2012. i need currency to be placed in top of geography or geography below currency.
I have a cube with a fact table and 3 dimensions. One of the dimensions is a type 2 and surrogate key is stored in fact table. If i query the database, the dimension attributes display correctly, however the cube is always displaying the latest dimension attribute and not preserving the history.
The measures are correct for the time period displayed, but the dimension attributes always show the latest values.
I have 5 cubes, and hierachy defined for all cubes. for example:geography database with 5 continents as cubes and contries as dimensions.Now when i am doing security restrictions on my dimension ex: In USA dimension if i want only to give access to texas region then i should be able to see only texas cities. But i cansee all the states under USA even after selecting only Texas region under Dimension data tab inside ROles section in SSMS.I have tried security at database ,cube level as well as dimension level.But still not working.is that because of some wrong design of cubes or something related to database design.? I am not able to undersand that except roles everything in my cubes or datawarehouse is working fine without and defect in data.
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?
In my SSAS Cube I have created a dynamic named set "top 10 e-learnings by language" which consists out of a set of tuples. Each tuple has two attributes out of the same base dimension "training": attribute 1 is "sprache" (language) and attribute 2 is "training text".
Normally a named set would be automatically visible in Excel Pivot under the dimension you used to create the named set, but it seems that named sets with tuples which have more than one attribute are placed in a separate folder "Sets" in between the measures and dimensions.Additionally in the SSAS cube browser this named set is not visible at all.Is there any way to tell the named set in which dimension it should appear or any workaround?
I am working on SQL 2012.We have a SSAS Cube build. On top of it client use Excel to connect to SSAS Cube and See the reports.My Cube process every hour and take almost a 1-2 min to Process.When ever End user/Client See or refresh the Excel report (Which use Cube as Source),WHEN CUBE IS PROCESSING ,they get an error that Source is not available
We Have tried best but cannot bring down the Processing time of the cube to 3-5 Second , so that End user don't face report refresh issue at the moment of cube processing
Requirement :In Case End User see the report while Cube is processing from back end , Instead of Error they should see some customize Msg which we can provide some thing Like "Data is Refreshing , please wait ".
I get the following error while processing a SSAS tabular model (2014) on a new server.The SSAS service on this server is running under a login which has access to the SQL server data sources. I tried changing the provider to OLEDB from SQLCLNI11 in the connection string but that doesn't work too. The error message isn't useful to debug further.
The cube processing succeeds on a different server. I scripted out the cube DB and ran it on the new server and am trying to process full but it fails with the following error.
Error Message: The operation failed because the source database does not exist, the source table does not exist, or because you do not have access to the data source.

For Example: I have one dimension named as "Name", Under this I have "FirstName" and "LastName" Attributes are there.But when i drag "Name" dimension, By default "First Name" dragged. But i Want "Last Name" should drag.
I create a Dimension Date using SSAS 2008 but when i execute the dimension and i go to see the result i have this result:the result is not sorted..what i need is having the result order by year i mean i have Calendrier 2020,Calendrier 2019 ...
I have a dimension like Districts, Under that 2 Attributes are there i.e,District ID and Districts. When i drag Dimension "Districts", in OLAP grid it come District ID first. But i want Districts to drag first. How can we sort Attributes(District ID and Districts) for a dimension.
As u can see there is two company references in my fact table, and the schema is in snowflake. My customer requirements state that the Contracts' amounts can be aggregated/filtered for/by, ServiceProviderCompany, its city/profession or ClientCompay, its city/profession.
First thing came in to my mind is to dublicate whole dimension structure (one for serviceproviders, one for clients), which i thought that there should be another way around?
I am creating an SSIS Script Task that will be used to process SSAS dimensions and partitions and ideally log the details of each in a table. Any info on the benefits or drawbacks of using the built-in SSAS parallel processing as opposed to doing it manually in a multi-threaded "Parallel.Foreach" loop using the .NET AMO library.
In my testing, when I use a Parallel.foreach loop, I am able to obtain and log information about the object such as end time and time to process immediately after each object is processed. This allows me to keep a history of processing time for each object:
public void processDimensions(Server Server, Database Database, ProcessType processType) { Parallel.ForEach(Database.Dimensions.OfType<Microsoft.AnalysisServices.Dimension>(), d => { DateTime beginTime = DateTime.Now; try { d.Process(processType);
[code]....
If circumventing the built-in SSAS parallel processing is not best practice I'd like to know in advance before I go too far down that path.
I have an SSIS and SSAS project in the same solution. I need to debug the SSIS package regardless if there is an error or two in the SSAS project. Is there a way to ignore the SSAS project while I debug the SSIS package?
I have been tasked with processing a large tabular cube using SQL AS 2014 (with latest CUs).The three Fact tables having 1.2 billion rows (in each table) have been divided into 30 vertical partitions to aid in parallel processing. So around 40 million rows per partition.
Using SQL Profiler to monitor the Row counts (IntegerData) of records processed seems to max out around 2 million rows per minute, then tapers down to about 200k /minute.
The processing is taking over 14 hours and I need to get it lower if possible. The server has 48 cores (2.66MHz) and over 1TB RAM installed. But I really don't ever see CPU exceed 20% having a maximum of 206 threads running on the instance msmdvr.exe
Available RAM is always at least 30% (or 300GB).
I have increased the Vertipaq MIN/MAX 60%/80%
I have increased the OLAP / Processing / Max Thread Pool Min 500 and Max to 1000.
The connection properties have been increased to allow 100 connections, the majority of the processing consumes about 92 connections for the 90 large partition views for the facts.
What can be done to increased the server resource utilization and decrease processing times?
I am trying to implement data masking based on user login and not sure why this is not working. I have the dimensions DimBrand, DimProduct and DimUser. I should mask the BrandCode with 'XXXX' nothing but in the report all the BrandCode should appear but few of the code will be masked if the user is not belongs to that group. I have a fact table FactProduct in this. In the cube I created all these 3 dimensions and the fact table. I created a new dimension DimBrandMask and I separated the code over there with a relationship with the actual DimBrand dimension. In the cube a reference relationship is set up with the measure group. Created a role with read access.
In the dimension data tab of role I put the below MDX to allowed set.
When i add a dimension to the cube dimension without any relation in my dimension usage to any measure group my units are going down.However when i remove the dimension from the cube am getting the correct values.
I have a cube that we are processing nightly via an Analysis Service Processing Task in SSIS. In order to increase the performance of the processing time, we elected to use a lot of rigid dimension attributes, and do a full process of everything in the SSIS task. The issue that I am having is that after that task completes, I need to go into Visual Studio to deploy the cube becuase we are unable to browse or use the cube. This issue seemed to start once we changed the SSIS Analysis Service Processing Task to do a full process on the dimensions, rather than an incremental.
I would expect that once development is done, and it is processed and deployed, that is it. My thinking is that the SSIS task should just update the already deployed cube,
I've run into a problem building a new olap cube. It's taking 15 minutes or more when pulling on a dimension before I've even pulled on any measures. This happens in Excel as well as Management Studio. When it does display it seems to only show dimension members that it has data for. In addition, running profiler seems to indicate that it queries each of my partitions when it's doing this. I know that in my last cube if you pulled on a dimension, no members would show up yet and it would be fast. However I can't seem to find the property that's telling it not to query the partitions to determine what members to show. Any ideas?
I have a problem with processing my cube. My fact table (with telephone data) contains about 400,000 records... which is increasing rapidly (400,000 records is about 8 months of data)... I have a few dimensions: Dimension User: about 200 records Dimension Line: about 200 records Dimension Direction: 4 records Dimension Date: 365 records for each year Dimension TimeInterval: with 24 records
So far so good... when I process this dimension I have no problem.... However, when I add a dimension (CalledNumber, with exactly 101 records) the processing hangs as soon as it starts...
The SQL performed when processing the cube looks like this:
SELECT field1, field2,... fieldn FROM table1, table2,.... tablem WHERE (table1.id=table2.table1id) AND (table2.id=table3.table2id) ...
When I execute above SQL in the Query Analyser from SQL Server Enterprise Manager, it ALSO hangs...
I am not really suprised by that, because this SQL first create a huge table of 400,000 x 200 x 200 x 4 x 365 x 24 x 101 records and after that works through the WHERE statements to filter out the appropriate records.
for me it would be more logical to use the following code to process the cube, but that cannot be changed in Analysis Manager:
SELECT field1, field2,... fieldn FROM table1 LEFT JOIN table2 ON (table1.id=table2.table1id) .... LEFT JOIN tablem ON (tablem.id = tablem-1.tablemid)
When I execute above SQL in the Query Analyser from SQL Servel Enterprise Manager, it does NOT hang, but performs the query in about 35 seconds.... But Analysis Manager does not allow me to change the SQL used for processing the cube...
What can I do to add more dimensions to my cube... (It will be more anyway after adding the CalledNumber dimension)?? any suggestions?

Apparently this translates to the error DTS_E_ADDROWTOBUFFERFAILED.
This incremental load is trying to add several hundred thousand rows and it appears to get to around 10K or so and then fail. I can't seem to find any KB articles related to this problem. Does anyone have a clue what may be happening here?
I do have an incremental load of the same type that is working but I am continually getting the following warning when the load is running:
"The buffer manager detected that the system was low on virtual memory, but was unable to swap out any buffers. 6 buffers were considered and 6 were locked.

i am getting the following error when i am processing the cube in SSAS 2008...Errors in the back-end database access module. The size specified for a binding was too small, resulting in one or more column values being truncated.

I have a have a relatively simple SSAS cube that I'm trying to display in a matrix but the order of the data is not correct. The rows of the matrix are a time hierarchy and the query designer produces the correct MDX and when I run the MDX in the data tab, the order is correct. However in the report preview tab, the order is incorrect. Specifically, the time hierarchy looks like this Year-Month-FullDate. The report is ordering the Months like this 1,10,11,12,2,3,4,5,6,7,8,9. I ran the MDX query in Sql Studio and the order is correct, and I used Excel to consume the same cube and it produces the correct order.
The report is somehow treating the Month like character data instead of numeric, how do I fix this?
I have a package that works fine locally but doesn't work when I deploy it to the server (and reset the connection strings to the local DB and AS instances that are running on the same server)It's not the usual permissions issue; I'm getting something about the SQL Browser not running (it is) and named instances. But my SSAS instance is the default unnamed instance?
The error message is "errors in the oledb provider. could not connect to the redirector. ensure the sql browser is running on the "." server" then another error with "error while retrieving name instance information".I've tried referencing the ssas server using its ip, ., hostname but the package craps out in a few sec
I've verified that the SSAS server is running and i can connect to it using ssms/tableau/excel etc.I've tried changing the service account of the sql browser to use local system.
All I get back is an error message of "Analysis Services Processing Task Error: A Connection cannot be made. Ensure the Server is running" The server is running, I can process the cube by connecting to the AS instance and right-click processing it.
I can process the cube by running the SSIS task inside of SSDT Just when I deploy the SSIS package (in Project mode) and then execute it do I get the error message.
SQL Server, SSAS, and SSIS processes are all running under the same account. SSAS is on a separate server from SSIS and SQL if that matters.

I was successful in processing the cube, however the problem is everytime I drag the dimension on the columns field in Pivot tables the Thresholds start to break up the other amounts that I have on display like Acquisition Costs, Tax amounts. I am only interested in showing the breakdown of Premium amount measure by the Threshold dimension.
somehow 'Hide' or 'prevent' the Threshold dimension from breaking down the other measures on the Pivot and only breakdown the amounts for Premium?
how I should structure my tables in SQL or any MDX queries to resolve this.
Hi,This is probably a classic scenario with a shared dimension that weneed to use in different cubes, where all fact tables do not offer thesame level of detail. Dimension is snow-flaked.The cube that's causing me troubles was designed by marking the lowestdimension level Diabled and not Visible. This allows me to get rid ofone of the snow-flake tables (the one with the lowest level), thusallowing an INNER JOIN with the remaining table which has a level ofdetail corresponding to the fact table.When processing the cube, I get a 'member with key '[blah]' was foundin the fact table but was not found in the level '[blah]' of thedimension '[blah]'' that seems to indicate that none of my fact foreignkeys exist as primary keys in the dimension table. However if I thenattempt to query the cube, all data seems to be there.Would anybody be in a position (and willing ;-)) to share his/her ownexperience working around a similar issue?Thanks,SRL
