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?

  • Used itunes for first time. Now when I open Firefox none of my previous tabs show and it opens itunes. I want my old tabs back!

    Firefox automatically opens to itunes. I seem to have lost all my other tabs. When I look at firefox options, it still says it will open to my home page but it does not. It opens to itunes and all my other tabs are missing.

    It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
    Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.
    * Help > Troubleshooting Information > Profile Directory: Open Containing Folder
    * http://kb.mozillazine.org/Profile_folder_-_Firefox
    If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
    Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

    hi,
    while browsing the cube data Excel the circle pointer starts to spin and the excel go into a not-responding state,any recommendations to improve performance in excel? 
    I have 20 measures and 8 dimensions.
    while filtering data by using dimensions in excel it is taking so much time.
    Ex:
    I browsed 15 measures in excel and filtered data based on time(quarter  wise) and other dimesion product. It is taking long time to get  data.
    Can you please help on this issue.
    Regards,
    Samba

    Hi Samba,
    What're the versions of your Office Excel and SQL Server Analysis Services? It will be helpful if you can share the detail computer resource information to us while encountered this issue.
    In addition, we don't know your cube structure and the underlying relationships. But you can take a look at the following articles to troubleshoot the performance issue:

  • Use of HttpSession and Performance Issues

    I am working on an application where we are storing data in a user's HttpSession. The application consists of several modules. Each module consists of sub-modules. A sub-module contains various data which is display to the user as multiple tabs with each tab displaying a JSP. The data displayed on each JSP is stored in the HttpSession for a given browser window. So if the user only has one browser window open there will be one entry in the HttpSession for that window containing the data for the various tabs of the displayed sub-module.
    This effort has been a transition of a legacy Powerbuilder application over to the Web. We have noticed, along with the users :( some delays in displaying data. We only connect to the database during the initial retrieve of the data. Once the data for a sub-module is retrieved it is displayed and stored in the HttpSession. As the user makes modifications we modify the appropriate structure in the HttpSession. When the user Saves the data, that is when we make a connection to the back end database.
    What is the best way to determine if there are true performance issues or whether we are just experiencing the cost of doing business across the Web?
    Does using HttpSession cause potential performance issues?
    We are also using the Netui tags in the JSP's and we have discovered some overhead when tag ids are used. In most places we have removed the tag ids since extra script is generated when they are used in conjunction with the Netui tags. This has helped in some places with the rendering of data on a page.
    Anyone have any suggestions/ideas?
    Thanks in advance.

    Is anybody using MODEL in production?
    How is the performance - is there any real problems?I used a MODEL query last year to simulate a FIFO queue and calculate average stock prices.
    It performs pretty well, but the volume of data is small though (~200k rows processed per batch session).

    when my lightroom opens up I keep getting an error message that states, "Lightroom encountered an error whne reading from its preview  cache and needs to quit" I have relaunched it a number of times and keep getting the same message. Any thoughts on how to fix this?

    You need to delete your preview cache and have Lightroom rebuild it.   Cache location can be found here.

         The disk space is running VERY low and I would love an idea. I make videos and upload them to youtube and I need space to do that. Thanks for your time!                              
                                       If you have an idea please respond!

    You should never, EVER let a conputer hard drive get completely full, EVER!
    With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
    If it does, it's time for some hard drive housecleaning.
    Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
    Have you emptied your iMac's Trash icon in the Dock?
    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
    If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
    Look though other Apple Mail folders like the junk mail and delete the mail that is in there. Look through your sent items folders and see there is any mail in there that can be deieted.
    Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
    Other things you can do to gain space.
    Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
    This app will help you locate files that you can move/archive and/or delete from your system.
    STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
    Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
    Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
    Download an app called OnyX for your version of OS X.
    When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
    Typically, iTunes and iPhoto libraries are the biggest users of HD space.
    move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
    If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
    Good Luck!

  • Computer keeps Configuring and setting up for first time use

    I have a toshiba A505-S6980 that has been working fine for a couple years.  Recently I had performance issues and suspected virus, spyware so I did a recovery with the original discs I made when I first got the computer.  Four of the six discs reloaded fine.  It did not ask for the last two discs "Environment 64 bit and Applications and Drives.  I also have a System Repair disc.  After loading the four recovery discs the computer now keeps recycling between preparing for first time use, configuring system, reboot and then back to preparing for first time use,etc.  I think I'm close to getting this, but need a last bit of help.
    Thanks

    It's been a couple days since you posted this problem. Did you get anywhere, or are you still stuck in that loop? If it's still stuck, you may just want to perform the recovery again.

  • [SOLVED] Getting freezes after using dwm for some time and exiting it

    Hello, I have an Asus Ux51, with a fresh (less than a month) arch installation. If I recall correctly I had a couple of freezes in other occasions but I don't remember much about those so I rather focus on the only freeze I can more or less reproduce and I've been having lately. After using dwm for some time with a couple of programs opened (rTorrent, browser, and some terminals for instance), if I close dwm or just press the power button to shut down, it starts closing everything and either stays with a black screen, or hangs while X prints the log information. It's not always though, for example, if I just boot it, open dwm and close it without giving it much use it usually closes fine.
    Tried googling a bit to see the usual ways to troubleshoot this but didn't get really far.

    Found this recent thread in the forums, I'll give REISUB a try late, but the times it freezed I remember trying to blindly reboot it, or switching off virtual console and couldn't.
    In case it's of any use, this is my # uname -a
    Linux arch 3.10.3-1-ARCH #1 SMP PREEMPT Fri Jul 26 11:26:59 CEST 2013 x86_64 GNU/Linux
    Could it have something to do with the nvidia optimus setup that this laptop has? When installing arch I found out that there was no support yet for it so I'm just using the intel drivers (following what the arch wiki said).
    Any ideas or advice to point me in the right direction would be very much appreciated.
    Thanks in advance.

    I don't start st in my .xinitrc. I launch it from dmenu and usually everything is fine. If I launch it from dwm's internal command using Alt-Shf-Return, X freezes 100% of the time. A workaround was suggested by st's main developer to call st like this:
    static const char *termcmd[] = { "/bin/sh", "-c", "st", NULL };
    but it didn't work for me.
    Very rarely X will freeze anyway. I haven't been able to pin it down. When X fails, my journal returns this:

  • Mac 10.9.5 trying to launch Illustrator CS6 for first time and prompts Java even though I have Java 8 installed.

    Mac 10.9.5 trying to launch Illustrator CS6 for first time and won't launch, prompts for Java 6 even though I have Java 8 installed!
    Apple says Java 6 is very insecure and not to use it.  I have the latest Java installed.  Why won't Illustrator launch?  What else can I do?

    tm,
    I believe you should be able to get round the issue by following this:

    It is even more thoroughly described in this thread, see post #3 on by gator soup:

    i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. Am i keeping my files in the portable hard disk when I will connect it again with the macbook or the time machine will erase all?
    I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard drive

    Welcome to Apple Support Communities
    Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.
    If you want more information about Time Machine, read the Pondini's site > http://pondini.org

    Using iPod shuffle 4th generation for first time and receiving the error : one of the USB devices attached to this computer has malfunctioned, and windows does not recognize it. For assistance in solving this problem, click this message.

    I was hoping it would be something like a USB device conflict, but now the shuffle is the only thing connected...
    This article was one of the ones you linked to above in your initial post
    http://support.apple.com/kb/TS1369
    Under Part 9. Verify that USB drivers are installed, did you try the steps in If only "Unknown Device" appears?  That appears to be your situation.
    Also, you said that the shuffle initially worked well enough to do a sync, then it had the same problem again.  If you can get it to work again initially, before doing anything else, try the following.  Select the shuffle in the iTunes sidebar, under DEVICES.  Over to the right, go to the Summary tab.  By default, the checkbox for Enable disk use should be unchecked.  If so, check it and Apply the change.  See if that makes any difference. 
    (If Enable disk use was already checked, try unchecking it and Apply the change.  Basically, set it the "other way" and see if there is any improvement.)
    NOTE:  When disk use is enabled, you have to eject the iPod in iTunes before disconnecting it physically.
    If the disk use change makes a difference, that may provide a clue about the actual cause.
