SSAS Cube Role Issue

Hi,
I want to grant access to a user to a SSAS database. I'm able to add him to two databases but when i try to add him to the third database, it seems to hang. I have tried both GUI and XMLA query for this.The ALTER ROLE XMLA query(after extracting the member
tag from the role query of another database) gives the following error in a couple of seconds:
"Transaction errors: Aborting transaction on session 115585.
Transaction errors: Aborting transaction on session 115585. Transaction errors: Aborting transaction on session 115585.
I had to kill the query eventually. It doesn't seem to be a user issue as a simple alter role of the existing role also gives this error.
I'm using SSAS 2005. Its strange that it is showing this issue suddenly today. Can someone please help?
Regards,
Sumit

A restart of the SSAS service worked in this case. Never thought it would be as simple as this.

SSAS cube role members magically disappear overnight

Hello,
We are running SQL Server 2008 SP1 CU4 and I have been experiencing an occasional issue whereby our cube role members disappear - resulting in the user-dashboards failing on our website, so I am keen to resolve this.
Some background:
-We have two roles, one with 2 members and one with about 15-20. When the issue occurs, both roles lose their members but the roles themselves remain.
-The SSAS database is set to do a full process every night at 11pm.
-I deploy cube changes by backing up the cube from my development machine, and restoring to the server. My dev machine is on a different Windows domain. When I restore I select "overwrite security information" but am always very careful to select
"Skip Membership". The restores always complete successfully, and I can immediately re-process the cube and confirm that the original members are still there and functioning normally.
-I suspect that this issue is related to the nightly re-process of the database, however I have tested this theory by checking the membership the day after I've completed a cube deployment and everything is still Ok.
-This just happened again last night. I reviewed the server logs and saw that the server rebooted last night at 9pm, followed by the cube re-process at 11pm.
-I noted this morning that the role membership has a single SID listed, and I can confirm that this is the SID of my local user account on my local machine. So it appears that when the issue exhibits itself, the cube is reverting back to the role membership
contained in the restored database, even though I told it to skip membership.
To fix it this morning, I re-added the members and have saved a script to automate the process next time it occurs. I am aware I could run this script after every re-process just to be safe - but I'd rather stop unpredictably losing the configuration
than automate the re-establishment of it!
What gives!? Any suggestions appreciated.
Michael

Hi Abbas,
We're clear on the difference between "build" and "process" right?
In my case, the cube processes every night - whereas we only change the design of the cube occasionally, maybe once every 2-3 months - therefore we are only
building it every 2 or 3 months.
Because my dev machine is on a totally different domain to the SSAS server, I can't (or at least I didn't think I could) specify the accounts that are members of the various roles during development. I do this with the aid of a script every time we
deploy out a new version of the cube to the SSAS server.
So, after a build and deploy - the cube role membership is perfectly fine and behaves as expected for all users. The thing that's puzzling us is that the role membership occasionally appears to unpredictably revert to prior settings (i.e. reverting
back to my deployed role membership config prior to running my script to set the correct role membership).
The cube can be running fine for several months and then suddenly I get a call in the morning about users not being able to access the cube. I find that the server was rebooted overnight and the role memberships have disappeared - this is not an immediate
result of a BIDS build/deploy as I think you are suggesting Abbas.
This hasn't occurred again since my last post in March this year, fingers crossed the problem has gone away.
Thanks,
Michael

Hi ReddeppaG2580,
According to your description, you get the above error when processing a cube. Right?
Based on the error message, the issue occurs on the dimension 'Package Download Source'. So check the involved tables and the query for this dimension. Check the attribute 'Package Download Source' in the dimension. If you still can't find some issue, try
to recreate that dimension. Please refer to link below:
Create a Dimension by Using an Existing Table
If you have any question, please feel free to ask.

Cache and performance issue in browsing SSAS cube using Excel for first time

Hello Group Members,
I am facing a cache and performance issue for the first time, when I try to open a SSAS cube connection using Excel (using Data tab -> From Other Sources --> From Analysis Services) after daily cube refresh. In end users
system (8 GB RAM), for the first time, it takes 10 minutes to open the cube. From next run onwards, its open up quickly within 10 secs.
We have daily ETL process running in high end servers. The configuration of dedicated SSAS cube server is 8 core, 64GB RAM. In total we have 4 cubes - out of which for 3 is full cube refresh and 1 is incremental refresh. We have seen after
daily cube refresh, it takes 10 odd minutes to open the cube in end users system. From next time onwards, it opens up really fast with 10 secs. After cube refresh, in server systems (16 GB RAM), it takes 2 odd minutes to open the cube.
Is there, any way we could reduce the time taken for first attempt ?
Best Regards, Arka Mitra.

Thanks Richard and Charlie,
We have implemented the solution/suggestions in our DEV environment and we have seen a definite improvement. We are waiting this to be deployed in UAT environment to note down the actual performance and time improvement while browsing the cube for the
first time after daily cube refresh.
Guys,
This is what we have done:
We have 4 cube databases and each cube db has 1-8 cubes.
1. We are doing daily cube refresh using SQL jobs as follows:
<Batch xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
<Parallel>
<Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200">
<Object>
<DatabaseID>FINANCE CUBES</DatabaseID>
</Object>
<Type>ProcessFull</Type>
<WriteBackTableCreation>UseExisting</WriteBackTableCreation>
</Process>
</Parallel>
</Batch>
2. Next we are creating a separate SQL job (Cache Warming - Profitability Analysis) for cube cache warming for each single cube in each cube db like:
CREATE CACHE FOR [Profit Analysis] AS
{[Measures].members}
*[TIME].[FINANCIAL QUARTER].[FINANCIAL QUARTER]
3. Finally after each cube refresh step, we are creating a new step of type T-SQL where we are calling these individual steps:
EXEC dbo.sp_start_job N'Cache Warming - Profit Analysis';
GO
I will update the post after I receive the actual im[provement from UAT/ Production environment.
Best Regards, Arka Mitra.

Performance issue in browsing SSAS cube using Excel for first time after cube refresh

Hello Group Members,
This is a continuation of my earlier blog question -
https://social.msdn.microsoft.com/Forums/en-US/a1e424a2-f102-4165-a597-f464cf03ebb5/cache-and-performance-issue-in-browsing-ssas-cube-using-excel-for-first-time?forum=sqlanalysisservices
As that thread is marked as answer, but my issue is not resolved, I am creating a new thread.
I am facing a cache and performance issue for the first time when I try to open a SSAS cube connection using Excel (using Data tab -> From Other Sources --> From Analysis Services) after daily cube refresh. In end users system (8 GB RAM but around
4GB available RAM), for the first time, it takes 10 minutes to open the cube. From next run onwards, its open up quickly within 10 secs.
We have daily ETL process running in high end servers. The configuration of dedicated SSAS cube server is 8 core, 64GB RAM. In total we have 4 cube DB - out of which for 3 is full cube refresh and 1 is incremental refresh. We have seen after daily cube
refresh, it takes 10 odd minutes to open the cube in end users system. From next time onwards, it opens up really fast with 10 secs. After cube refresh, in server systems (32 GB RAM, around 4GB available RAM), it takes 2 odd minutes to open the cube.
Is there, any way we could reduce the time taken for first attempt ?
As mentioned in my previous thread, we have already implemented a cube wraming cache. But, there is no improvement.
Currently, the cumulative size of the all 4 cube DB are more than 9 GB in Production and each cube DB having 4 individual cubes in average with highest cube DB size is 3.5 GB. Now, the question is how excel works with SSAS cube after
daily cube refresh?
Is it Excel creates a cache of the schema and data after each time cube is refreshed and in doing so it need to download the cube schema in Excel's memory? Now to download the the schema and data of each cube database from server to client, it will take
a significant time based on the bandwidth of the network and connection.
Is it anyway dependent to client system RAM ? Today the bigest cube DB size is 3.5 GB, tomorrow it will be 5-6 GB. Now, though client system RAM is 8 GB, the available or free RAM would be around 4 GB. So, what will happen then ?
Best Regards, Arka Mitra.

Could you run the following two DMV queries filling in the name of the cube you're connecting to. Then please post back the row count returned from each of them (by copying them into Excel and counting the rows).
I want to see if this is an issue I've run across before with thousands of dimension attributes and MDSCHEMA_CUBES performance.
select [HIERARCHY_UNIQUE_NAME]
from $system.mdschema_hierarchies
where CUBE_NAME = 'YourCubeName'
select [LEVEL_UNIQUE_NAME]
from $system.mdschema_levels
where CUBE_NAME = 'YourCubeName'
Also, what version of Analysis Services is it? If you connect Object Explorer in Management Studio to SSAS, what's the exact version number it says on the top server node?

How to read ssas cube and role from Excel vba

Hi,
I want to read all roles and cubes in SSAS Db from Excel Vba.
1. First i want to read all the roles which was assigned to me
2. based on the role, i have to read all cube name
Please help me to
accomplish this task.

Hi Jack,
In Analysis Services, Each role contains members, by Windows username or by Windows group, and permissions (read, process, administrator). If the user has the permission to access SSAS database, then the account was contained in one or more roles. When connect
to SSAS database, we need to use an account to log on it, and SSAS will list all the cubes' name based on the role automatically.

SSAS cubes - fragments

Hi,
Hoping someone can help. I have defined a logical model over the top of a set of SSAS cubes in a single SSAS database. This consists of a summary cube and detailed cubes that relate to individual products. I would like to have a "Product" dimension that will allow the user to drill between the products and for dimensions at lower levels of granularity (i.e. that are only relevant to one product) data should be sourced from the relevant detailed cubes. Unfortunately although the summary cube has a product dimension the detailed cubes don't - when I try to map the detailed cube to the product dimension using an expression I get the following error message: "Target data source does not support the Complex Expression operation."
e.g.
Product Dimension has 3 products in it: Bikes, Cars and Boats. There is a summary cube that contains all 3 products and has the Product dimension defined.
There are 3 detailed cubes for Bikes, Cars and Boats that don't have a product dimension. In my mappings for the Product Name attribute of the Product dimension I have the following:
Logical Table Source..... Mapped As
SummaryCube..... Product.Product
BikeCube... 'Bikes'
CarCube... 'Cars'
BoatCube.. 'Boats'
Hope this explains it. I get the error message whenever I'm trying to get data from the detailed level cube.
Thanks,
Rob

Hi Platt,
By default, the default account for AS services 'NT Service\MSSQLServerOLAPService' has only public permission to few databases. If you haven't change the AS services account, or haven't grant the permission for this account, then you cannot deploy
the AS project to server.
So in your scenario, ensure the service "SQL Server Analysis Services" is running with a proper Log On As user. This user should have administrator permission on Analysis Services and the proper permissions on the database engine. To avoid this
issue, you can grant the SELECT permission for the default account for AS services to data source DB. Or you can change the services account to this domain user who has the corresponding to the data source DB.

Using FORMAT_STRING from SSAS cube - not working consistently

Here's the deal.
I've got an SSAS cube and I am scoping the format of the measures based on dimension members.
Like this.
scope(( [Account].[Level 5].&[I000900000] ));
format_string(This) = "(#,0,);#,0,";
end scope;
I'm then calling this format in the SSRS report using typical SSRS trickery and hacks.
Well. When I run the report for one date (this is a GL financial cube), this works perfectly. When I run the report for a different date, it all of a sudden doesn't work. When I view the data in excel through a pivot table, everything is fine.
It's driving me crazy. Has anyone else experienced something like this.

Hi Baracus,
Thank you for your question.
I am trying to involve someone more familiar with this topic for a further look at this issue. Sometime delay might be expected from the job transferring. Your patience is greatly appreciated.
Thank you for your understanding and support.

Dimension Security causing SSAS cube to slow down

Hi,
Experiencing problems with with the SSAS cube once its processed. Sometimes takes around 20 mins for the excel to load once you drag down any dimension.The cube has got no calc scripts/named sets etc.It has around 17 dimensions and one dimension(Employer)
has got 46 attributes and another (member)17.Others are pretty small.The Employer dimension is used twice as role playing and the both employer/member have got dimension security applied to it.There are about 6 roles have been set up to restrict access to
members in these dimensions.
The SQL profiler shows multiple "Query Dimension" (mostly for Employer dimension)followed by a lot of "Calculate Non Empty Current"s .Suspect that the delay is due to the dimension security expression evaluation.This only happens
during first access of the cube within a role and it's relatively quick when I'm accessing via a role which doesn't have dimension security applied to it.Is there anyway to automatically trigger this process right after the cube has been processed so that
it doesn't cause agony to the first user?

You could build a cache warmer that connects with EffectiveUserName=YourDomain\user1 on the connection string and loop through each user. But what is your dimension security expression? Maybe we can speed it up.

SSRS Parameter Drop downs are greyed out after changes to SSAS cube

Hi
I am facing a weird problem. I have 3 SSRS reports that are based on an SSAS cube. Few days back I deployed some changes to cube and everything works ok on dev environment. When I deployed the same changes to production, SSRS reports don't work. I don’t
get any error or anything when I click open the report but all the parameter boxes are greyed out. If I restore SSAS database from dev to production then SSRS reports work fine and I can select parameter drop downs. What could possibly wrong here. I have no
idea to what to troubleshoot here.
Thanks
Nik

Hi Nik,
Are you using render the report from a report snapshot? In contrast with reports that run on demand, it is not possible to specify a different parameter value for a report snapshot when the report is open. So the parameter textbox is grayed out. If the users
want to view the report with different parameter, we can select “Always run this report with the most recent data” option in “Processing Options properties” page.
Besides, if the issue is not in this scenario, we can try to edit the report with Report Builder to check whether the report is ok. Such as delete the parameters, then recreate them to check again.
If there are any misunderstanding, please elaborate the issue for further investigation.
Thanks,

Slow parameter from SSAS cube

Hi,
I've got a SSRS report which use a SSAS cube as source. In the report there are 5 parameters which are build in the Report builder 3.0 using the designer. The report server is a SQL server 2008 R2 with the latest updates.
The issue that I am having is when running the report if I would like to choose another value from one of my parameters then I open the parameters (drop-downbox)and select another value in the box - then it's like the drop-down box hangs for 3-4
seconds when I click out of the box before the value is appearing in the report, when I use the Report builder Tool. If I do the same in IE then the reports render for 10-15 seconds each time a new value is choosen.
Any Idea how to improve this?
The Parameter consist of only 5-6 values and it performs very fast if I execute the Query in the designer
I've attached the Query as it looks like for the parameter(hidden dataset):
WITH MEMBER [Measures].[ParameterCaption] AS [Company].[Company Name].CURRENTMEMBER.MEMBER_CAPTION MEMBER [Measures].[ParameterValue] AS [Company].[Company Name].CURRENTMEMBER.UNIQUENAME MEMBER [Measures].[ParameterLevel] AS [Company].[Company Name].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue], [Measures].[ParameterLevel]} ON COLUMNS , [Company].[Company Name].ALLMEMBERS ON ROWS FROM ( SELECT ( STRTOSET(@ReportingCurrencyReportingCurrency, CONSTRAINED) ) ON COLUMNS FROM [SALES])
(the issue is the same for all my parameters)

Hi HCMJ,
In your scenario, you said that "the reports render for 10-15 seconds each time a new value is choosen".
Report server performance is affected by a combination of factors that include hardware, number of concurrent users accessing reports, the amount of data in a report, and output format.
To find out how long it takes to process a report and which process phase take more time, we can review the report server execution log. We can use the report execution log to find out how often a report is requested, what formats are used the most, and
how many milliseconds of processing time is spent on each processing phase.
In addtional, i'd suggest you enable SQL Sever profiler to monitor the queries fired by the report, once you find some queries took a very long time to run, consider creating the smaller cube partition or optimzing the query by adding index or
partition to improve the query performance.

Connecting to an external SSAS cube in SSDT 2012 on Windows Server 2008 R2 Core

Good Evening,
We are experiencing issues when executing an SSIS package from a SQL Server job. However, when we execute the package locally, it is
successful. The package connects to an external SSAS cube using MDX. I have attached the error message below. The connection manager is OLE DB Provider for Analysis Services 11.0. We can successfully ping the external site where the cube is located from the
server with the job.
We are using Windows Server 2008 R2 Core. We are trying to access an external cube through HTTPS by sending a username/password in the connection string. This is sent through an OLE DB connection in SSIS. I found an article which says that "Because
there is no Web browser, you cannot activate a Server Core installation or access the Internet through a firewall that requires users to log on." Does anyone have any additional details on this...is this a futile effort?
Thanks - Brett

Hi Brett,
According to your description, you are experiencing the error when you connect to SQL Server Analysis Services database on a SSIS package, right?
In your scenario, you said that the package can be executed successfully on your local environment, the issue only occurs on the SSAS server. So please ensure that the provider was installed on the server. Besides, here is a blog which describe how
to configure the Analysis Services Processing Task in SQL Server 2012 Integration Services， please refer to the link below to see the details.

Service Not Available error with SSAS cube

Hi,
We imported Microsoft Analysis Services (SSAS) Cube into RPD using XMLA. While using the drill down feature in BI answers using presentation hierarchies, OBIEE is generating the following error
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: URL: http://<server>/<app name>/msmdpump.dll. The http return status is 503.< html><head><title>Service Not Available</title></head><body>Service Not Available</body></html>
However, drill down feature is working fine with attribute columns. Also the report is working fine up to certain level of drill down. In the log it is evident that OBIEE is generating multiple physical queries (with clause) to pull the data from the cube.
Is there any limit on the size of the mdx or number of mdx queries that msmdpump.dll can process? Is there any configuration that needs to be modified while working with SSAS cubes?
OBIEE version: 11.1.1.6.2 BP1
Much appreciate your time.

Hi Dhar,
Thanks for your reply.
Yes, your observation is correct. Changing the type of the hierarchies has some effect on the issue. I'm able to drill down to few more levels as the MDX generated by OBIEE in this less complex. But ultimately I'm facing the same issue after certain stage. I can only think of, the number of physical queries generated by OBIEE, as one of the possible reason for this. What is your opinion?
Interestingly, I tested the same RPD in 11.1.1.6.5 and I'm unable to reproduce in the issue so far in my testing . Is it a bug in 11.1.1.6.2?! However, upgrading to 11.1.1.6.5 is not an option for us at this stage.
Were you able to resolve the issue completely by only changing the hierarchy type? What version you have used in you project?
Thanks.

Using Non BI database as source to Build SSAS cubes and SSRS reports .

hi,
I have a requirement where I have to use existing database(OLTP) as my source to the SSAS cubes and then to build the reports.
Where for Cubes and Reports I uses SQL Server BI edition. But my existing source data will be in non BI database.
My questions are
1) Can I create Fact and Dimension Model in Non BI Db and connect the same to SSAS and SSRS? What you suggest?
2) Can I use cubes and reports without modifying the existing OLTP DB structure to fact and Dimension?
Thanks

1. Yes. you can
It doesnt necessary need to set up a OLAP system. However making design inline with OLAP would be easier to implement in SSAS
2. Again yes
But using OLTP designed tables in SSAS/SSRS would require some additional overheads at querying level like referenced lookups in SSAS vs lots of joins in backend queries in SSRS.

SSAS Cube Hierarchy Default Member, not aggregatable in pivot table multi select, Urgent

Hi All,
I have one problem in my project ssas cube. one of the dimension hierarchy, a value has been set up as default member in calculation tab.
The problem is:
When i filter (select multiple) this defaulted value and other value in excel pivot, it is always showing default member value instead of selected members aggregated value. if i remove default member it is working fine. Can you please provide work around
for this.
Please note that, if select multiple values within that hierarchy (this time not selected default value), aggregation is working fine.
Thanks, Rajendra

Hi Hirmando,
According to your description, the default member cause incorrect data when dragging a attribute that contain a default member to the FILTERS area, right?
I can reproduce this issue on my environment, when dropping this dimension in the filter area of my pivot table and select multiple members including the default member then only data for the default member is shown. Currently, it's hard to say the root
reason that cause this issue. In order to narrow down this issue, please apply the latest server pack and cumulative update.
Besides, you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback So that microsoft will confirm if this is a know issue.
