[SSAS 2012] OlapQueryLog is empty...

Hi All,
I try to retrieve users' queries on Analysis Server, so I follow the MSDN document and set up the QueryLog config as below.
1. CreateQueryLogTable --> True
2. QueryLogConnectionString --> use service account permission which is sysadmin on another DB
3. QueryLogSampling --> 5
4. QueryLogTable --> OlapQueryLog
after set up, i also check the latest msmdsrv log file which said "...Message: The query log was started....."
and also the table is created on DB.
After process few queries, I cannot see any records saved in table.... :(
Did anyone know what's going on here??
thanks in advanced.

Hi Jackie,
According to your description, the OlapQueryLog table is empty after you configure everything to retrieve users' queries on Analysis Server, right?
Based on my research, this issue can be cause by permission issue. By default, the SSAS service account requires more than db_datawriter role membership (and probably less than db_owner) in the database specified in the QueryLogConnectionString server property
to successfully insert log rows to the QueryLog table. Here is a blog that troubleshooting why OlapQueryLog table is empty, please see:

SSAS 2012 (SP2) - Connecting to a Named Instance in a Failover Cluster

I posted this question some months ago and never got a resolution...still having the same problem. (http://social.msdn.microsoft.com/Forums/sqlserver/en-US/4178ba62-87e2-4672-a4ef-acd970ac1011/ssas-2012-sp1-connecting-to-a-named-instance-in-a-failover-cluster?forum=sqlanalysisservices)
I have a 3 node failover cluster installation (active-passive-passive) configured as follows:
Node1: DB Engine 1 (named instance DB01)
Node2: DB Engine 2 (named instance DB02)
Node3: Analysis Services (named instance DBAS)
Obviously, the node indicated is merely the default active node for each service, with each service able to fail from node to node as required.
Strangely, when I attempt to connect to the SSAS node using the cluster netbios "alias" (dunno, what else it would be called, so I apologize if I am mixing terminology or somesuch), I am only able to do so by specifying the the alias _without_ the
required named instance. If I issue a connection request using an external program or even SSMS using Node3\DBAS or Node3.domain\DBAS, it appears that the SQL Server Browser is offering up a bogus TCP port for the named instance (in my case TCP/58554), when
in reality, the SSAS service is running on TCP/2383 (confirmed with netstat) -- which if I understand correctly after much, much reading on the subject is the only port that can be used in a failover cluster. In any case, I'm puzzled beyond words. As I think
through it, I believe I've seen this issue in the past, but never worried about it since it wasn't necessary to specify the named instance when I had SSAS requirements... It's only a showstopper now because I'm finalizing my implementation of SCVMM/SCOM 2012
R2, and for some strange reason the PRO configuration in VMM gets all butthurt if you don't offer up a named instance...
Thank you much for reading. I appreciate any help to get this resolved.
POSSIBLY NOT RELEVANT...?
I've properly configured the SPNs for the SSAS service (MSOLAPSvc.3) and the SQL Browser (MSOLAPDisco.3), with the former mapped to the SSAS service account and the latter to the cluster "alias" (since it runs as "NT AUTHORITY\LOCALSERVICE"
as is customary) and have permitted delegation on the service and machine accounts as required. So, I'm not getting any kerberos issues with the service...any more, that is... ;) I'm not sure that's important, but I wanted to be forthcoming with details to
help solve the issue.

When connecting to SSAS in a cluster, you do not specify an instance name. In your case, you would use the name of the SSAS IP address to connect.
See:
http://msdn.microsoft.com/en-us/library/dn141153.aspx
For servers deployed in a failover cluster, connect using the network name of the SSAS cluster. This name is specified during SQL Server setup, as
SQL Server Network Name. Note that if you installed SSAS as a named instance onto a Windows Server Failover Cluster (WSFC), you never add the instance name on the connection. This practice is unique to SSAS; in contrast, a named
instance of a clustered relational database engine does include the instance name. For example, if you installed both SSAS and the database engine as named instance (Contoso-Accounting) with a SQL Server Network Name of SQL-CLU, you would connect to SSAS using
"SQL-CLU" and to the database engine as "SQL-CLU\Contoso-Accounting". See
How to Cluster SQL Server Analysis Services for more information and examples.

SSAS 2012 Tabular Error: The operation was cancelled because of locking conflicts

I have a 800 mb SSAS database that I refresh(Process current day partition) every 30 minutes. As soon as the processing starts all my users get error The operation was cancelled because of locking conflicts. I ran the deadlocks trace as described in http://blogs.msdn.com/b/sql_pfe_blog/archive/2009/08/27/deadlock-troubleshooting-in-sql-server-analysis-services-ssas.aspx
but all I see is the processing start and all the users getting the error ("The operation was cancelled because of locking conflicts") 22 mil sec after the processing starts.
I also ran "select * from $system.discover_locks" but I only see lock types 2,4 and 8. None of which seem to be exclusive
This is SSAS 2012 with sp 1
Database Architect

Hi Derek,
According to your description, you get the dead lock error when processing partition. Right?
In Analysis Services, this error occurs when lock manager detects a dead lock. Lock type 2,4 and 8 can also have two transactions waiting each other and cause deadlock. In this scenario, please check the Dead Lock Graph in SQL Profiler
and find the related processes. Check what the processes work for to see if you need to do parallel processing or process other objects before partition processing.

SSIS Connection Manager: MSOLAP100 where is the one for SSAS 2012 ?

I have an SSIS project under SSDT, that should process a SSAS 2012 Cube, when I setup the connection, the SSIS Connection Manager gives me only MSOLAP100 as a possible connection manager type. From my understanding this is the one for SQL 2008 R2. Where
is the one for SSAS 2012 and how can I enable it ?
I feel this is a bug in SSDT:
I used another UI dialog and could create a new connection like this:
Still it says ConnectionManagerType MSOLAP100, however in the connection string I now have Provider=MSOLAP.5, this seems to be another SSDT bug.

If this issue can be reproduced in multiple machines, then you can you can submit a feedback at
http://connect.microsoft.com/SQLServer/Feedback and hope it is released in the next release of service pack or product.

SSAS 2012 multi-instance installation issue

Hello,
Just wanted to share an issue and the resolution. Any feedback will be appreciated.
Symptoms
After installing the second named instance of SSAS 2012 on the same machine the first instance stops working.
Cause
The problem is that the second SSAS instance installed on the same machine doesn’t create its own INI file, but overwrites the original one, created by the first instance. The second instance’s
service is configured to use the overwritten INI. Note that the overwritten INI is still located in its original folder, ex. C:\Program Files\Microsoft SQL Server\MSAS11.SSAS01\OLAP\Config\msmdsrv.ini.
As a result, the second instance’s service works well, but the first one will fail to start once it’s shut down for the first time.
Resolution
For the sake of simplicity we will use names SSAS01 and SSAS02 for the first and the second named SSAS instances installed on the same machine called SERVER01. The default instance root directory
will be C:\Program Files\Microsoft SQL Server.
1. Install both named instances normally, using same instance root directory, but separate folders for Data, Log. etc.
2. Browse to the first instance “Config” folder C:\Program Files\Microsoft SQL Server\MSAS11.SSAS01\OLAP\Config. Make sure that the file msmdsrv.ini exists and folder locations within it
point to SSAS02.
3. Browse to the second instance folder C:\Program Files\Microsoft SQL Server\MSAS11.SSAS02\OLAP. Make sure that the “Config” subfolder does not exist.
4. Create “Config” subfolder under C:\Program Files\Microsoft SQL Server\MSAS11.SSAS02\OLAP
5. Change folder permissions:
In C:\Program Files\Microsoft SQL Server\MSAS11.SSAS01\OLAP\Config
Remove SQLServerMSASUser$SERVER01$SSAS02 local group
Add SQLServerMSASUser$SERVER01$SSAS01 local group with Full permissions
In C:\Program Files\Microsoft SQL Server\MSAS11.SSAS02\OLAP\Config
Add SQLServerMSASUser$SERVER01$SSAS02 local group with Full permissions
6. Copy INI file:
C:\Program Files\Microsoft SQL Server\MSAS11.SSAS01\OLAP\Config\msmdsrv.ini
To:
C:\Program Files\Microsoft SQL Server\MSAS11.SSAS02\OLAP\Config\
7. Edit the original INI file: C:\Program Files\Microsoft SQL Server\MSAS11.SSAS01\OLAP\Config\msmdsrv.ini.
Replace all “SSAS02” appearances with “SSAS01”.
8. Edit Registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSOLAP$UATSSAS02]
Change ImagePath value to:
"C:\Program Files\Microsoft SQL Server\MSAS11.UATSSAS02\OLAP\bin\msmdsrv.exe" -s "C:\Program Files\Microsoft SQL Server\MSAS11.SSAS02\OLAP\Config"
9. Start the services for both instances.

SSAS 2012 , Role- Limit of users

Hi Experts ,
I am working on SSAS 2012 Cube .
I am implementing Security on my cube for which I have created 2 Roles.
Question: I need to know how many users can be added in one Role (Member Ship Tab)? What is the maximum limit ??

Hi Rihan,
According to your description, you want to know the maximum number of users can be add into a role, right?
Here is a document that the list the maximum sizes and numbers of various objects defined in Analysis Services components under different server deployment modes.
http://technet.microsoft.com/en-us/library/ms365363(v=sql.110).aspx
However, the maximum number of users can be add into a role is not specify on that document. As per my understanding, we can add any numbers of users to the role as we want. In your scenario, how many users do you need to add into this role?
If you really need to know the maximum number, you can open a support case with Microsoft. Visit this link to see the various support options that are available to better meet your needs:

SSAS 2012 Tabular. Analysis Services Query Log not working

Hello.
It is possible to configure Analysis Services Query Log on SSAS 2012 Tabular (11.0.3321) server? Or this feature works only with Multidimensional server mode?
It is not a problem for me to configure Query Log on Multidimensional server. But when I'm trying to do this in Tabular server result is always the same: table S_OlapQueryLog created but no data there.
This problem exist in our production server. And is fully reproduced in test environment. This problem was reproduced with SQL 2012 RTM, CU4, SP1 and SP1 CU1.
I tryed to configure Analysis Services Query Log by using SQL account. Later by using windows authentification. Accounts was db owners. Later I have used accounts with sysadmin rights. Results was the same.
In msmdsrv.log i can find only related events like this:
(12/7/2012 9:22:59 PM) Message: The query log was started. (Source:
\\?\P:\Olap\Log\msmdsrv.log, Type: 1, Category: 289, Event ID: 0x41210003)
(12/7/2012 9:25:03 PM) Message: The query log was stopped. (Source:
\\?\P:\Olap\Log\msmdsrv.log, Type: 1, Category: 289, Event ID: 0x41210004)
I'm stuck completely with this functionality. So if someone was much luckier than I please write to me.
Regards
Audrius

I agree with Gerhard's comments, but there are a couple of additional points
- I am not 100 percent sure if queries that are answered by the SE cache are recorded in the query log
Queries answered by the SE cache are not definitely not recorded in the QueryLog. So depending on the types of queries and the design of your cube you could possible miss a large proportion of the actual end user queries.
The QueryLog records the QuerySubcube events and there are zero to many of these generated for a given end user query (zero if the query can be answered from cache). The optimizer may also choose to pre-fetch a wider range of data or to break a single range
into a few smaller requests so it is not a true indication of the actual query that the end user generated.
Doing a trace is the only way to catch the actual queries submitted by end users.

Edition Required for SSAS 2012 Multidim Partitoning Feature

I want to know what the edition requirement is for the SSAS 2012 Multidim Partitioning feature. In 2008 I recall that enterprise edition was required, but I cannot tell what the requirement is for 2012. Thanks.
Mark

Actually, the BI edition also supports SSAS partitions
http://msdn.microsoft.com/en-us/library/cc645993.aspx#SSAS. BI edition doesn't support partitioning in the DB Engine though so each SSAS partition would likely most efficiently be sourced from a separate DB Engine table rather than being aligned to the
partitioning function used to partition a single fact table.

Converting a SSAS 2008 R2 database into a SSAS 2012 Tabular database

Hi,
I'd like to know if it is possible to convert or migrate in whatever manner a SSAS 2008 R2 database (multidimensional) into a SSAS 2012 Tabular database.
Many thanks

Unfortunately there is no way to convert or migrate a multidimensional cube to a tabular model.
This MSDN article says ...
Because tabular is the newer solution, you might think that migrating an existing multidimensional solution to a tabular format is
the correct course of action, but this is usually not the case. Tabular does not supersede multidimensional, and the two formats are not interchangeable.
If you need to migrate a cube to tabular (maybe for performance reasons), unfortunately you need to build it from scratch. I believe the reason for this is that there are concepts that do not translate across the technologies. There are no good
3rd party tools that I'm aware of that even attempt to do this.

How do I install (just the required assembles without server licence) client library to a client machine so that I can invoke SSIS/SSAS 2012 remotely?

We are trying to figure the easiest way to install client lib on a machine to call SSIS/SSAS remotely (to a SQL Server 2012).
We have some .net code referencing SMO/AMO and Microsoft.SqlServer.Management.IntegrationServices.
1) For SMO, I found out this and it is quite clear about how to install on a client machine:
Installing SMO (SQL Server Management Objects (SMO))
http://msdn.microsoft.com/en-us/library/ms162189(v=sql.110).aspx
2) For AMO (analysis management object), I found out this but I did not see a clear instruciton of what and how to install on the client machine:
http://technet.microsoft.com/en-us/library/ms124924(v=sql.110).aspx
3) For SSIS call, I did not find anything talking about the client installation.
Can someone help us?
Thanks.

Hi Sofiya,
Thank you so much for your help.
For SSIS call, we are using
Microsoft.SqlServer.Management.IntegrationServices.dll
to call package deployed to SSISDB catalog at remote server using some .net codes.
I have few questions:
1) What is the difference between
Microsoft.SqlServer.Management.IntegrationServices.dll
and the dll you mentioned:
Microsoft.SqlServer.IntegrationServices.Server.dll
2) If we install SSMS, can we also get Microsoft.SqlServer.Management.IntegrationServices.dll? Put another way, if we install SSMS, will Microsoft.SqlServer.Management.IntegrationServices.dll be registeredin GAC?
3) If we install Microsoft.SqlServer.Management.IntegrationServices.dll at client machine, I assume we don't need to licence it. (Note: SSIS package itself will be running from the remote server, NOT the client machine which is used to invoke
the SQL 2012 packages).
Best regards,
Steven Rao
Hi Steven Rao,
Yes, you are right. When you want to start a SSIS 2012 package from a .Net application,
you need to reference the assembly of Microsoft.SqlServer.Management.IntegrationServices .dll. The Microsoft.SqlServer.Management.IntegrationServices namespace contains the classes and interfaces to manage the Integration Services catalog
on an instance of SQL Server. It is only available in the GAC. For more information, see:
http://microsoft-ssis.blogspot.com/2013/01/call-ssis-2012-package-within-net.html
I also do a test, if you install the media of SQL Server Management Studio, usually, these assemblies are located in following folder as screenshot.
In the folder, C:\Windows\assembly

SSAS 2012 Deployment Wizard - A connection cannot be made.

Hi
I have a virtual server of Windows 2012 Standard on USA from a cloud provider. I installed SQL 2012 and it is stand-alone server, not part of domain.
I am in Australia developing SSAS to be deployed to the server above. The problem I am facing is that even though SSAS is running on that server, I can not deploy the project to the server both in Bids and SSAS deployment Wizard. I can copy the project
to the server and deploy it there in Bids.
I am just wondering why I can not do it. I created a sample cube on the server and can connect to it using Excel.
I have a feeling that one of the requirement to deploy a project remotely is to be a part of domain - Making my computer or my credential as an admin to the SSAS server to deploy the project. Am I right? or is there something I am doing wrong?
Firewall is ok. I got the right ip address. I just can not deploy remotely?
What's the requirement of the remote deployment?
Kind regards

Hi SQLMa,
According to your description, you instal SQL Server Analysis Service instance in the Virtual Machine of Windows Azure, now the problem is that you cannot deploy the SSAS project to this server, right?
In this case, you need to create the Virtual Network on the VM, and then connect to the Azure VM through the Virtual Network. Here is a blog which descrie build an OLAP Farm in the Cloud with Azure Virtual Machines step by step, plese refer to the link below:

SSAS 2012 end Excel functions - mode.sngl doesn't work

Since I've used SSAS 2005 with Excel 2007 my Excel.Mode function worked fine.
Now we have migrated to SQL 2012 and we have installed Excel 2010 --> Excel.Mode is deprecated in the new version and the cube calculations that use this function won't work. The new Excel way to calculate mode is [mode.sngl] but I can't call it from cube
calculations.
I tried to replace the Excel approach with the MDX approach (link below) but the time to calculate is too slow.

Hi Mihai,
as I mentioned before I've tried different approaches (see the link) but I didn't find a good MDX solution to work around this issue.
Fortunately (for me) I have a certainty. The numbers involved in my calculation can only be between 0 and 9. Impossible to have more than 9 (cautionary) delivery (measure.[Num. Consegne]) a day for a product in a shop.
So I can work around in this (unconventional and maybe optimizable) way:

Script task error during the creation of partition by reading a table and using AMO - SSAS 2012

Hi,
I need to create SSAS (tabular) and process partitions in an authomatic manner. Moreover, the partitioning is respect to a category, an year and a month.
Category, year and month are resident on a table to read to create the SSAS partitions.
So, in a SSIS pkg:
a. I've created a data flow task to read the SQL Server table having category, year and month data,
b. I've connected the output of the ole db source as the input for a recordset destination, associated to an object variable,
c. I've used a for each loop container (ado enumerator) specifying the object variable and three variables, for category, year and month,
d. inside the for each loop container I've created a script task using AMO (visual basic) to control for any existing partitions, if not presents to create the new ones and then to process them.
For the first iteration, a new partition has been created and processed successfully, but then, for other category, year and month values the script task fails. I've controlled the code many times and I've tried to put returning messageboxes but I've found
anything. The error is a generic one and no other info are returned.
Well, any suggests to me in order to solve this issue, please?
Many thanks

Hi, thanks, I've solved adding to the code end the SSAS server connection termination.

How to Access cube deployed on SSAS 2012 Standard Edition hosted on AWS cloud

Hi,
We are planning for a BI reporting interface for a customer that has cloud based application (.aspx application) hosted on AWS. There is no ADS implemented on the Windows server hosted on AWS. The application uses custom authentication. The IP address of
the SQL server cannot be shared with the end user.
How will the end user be able to access the cube from Excel running on the client computer ?
TIA,
Ashish

Could you deploy msmdpump on the web server and have that be a proxy to connect to the SSAS server? Would HTTPS and basic auth work?

Using Get Data From Aggregation event class in SQL Profiler - SSAS 2012

Hi,
I'd like to understand better the use of the Get data from aggregation event class in SQL Profiler to monitor a MDX query and which info provide. Fe, does it return the MDX query? Is it possible to use this event class in order to monitor MDX query vs a
Tabular model?
In the TechNet documentation, this event class is handled briefly.
Thanks

Hi pscorca,
This event is raised when the storage engine reads data from an aggregation, it may have a negative impact on performance when turned on. If you need to monitor SSAS instance status, we can also use dynamic management view:
