Memory problem in BI query

Hello,
I have some short dumps about memory problems in my BI system (3.5) when I´m consulting a report through BEx. It shows the error STORAGE_PARAMETERS_WRONG_SET, and recommend to increase value of profile parameters:
- abap/heap_area_dia
- abap/heap_area_nondia
But if I check tx ST02 can see threshold of heap memory are never exceed,
Heap memory

What is wrong?? How can I tune it??
Thanks in advise.

It all depends on the OS your SAP is running on... I guess you are on on windows
Then you can get ride of many of theses params
Check note 88416 and delete the following  params :
em/initial_size_MB
em/address_space_MB
em/total_size_MB
em/max_size_MB
ztta/roll_first
ztta/roll_area
abap/heaplimit
ztta/roll_extension
abap/heap_area_dia 
abap/heap_area_nondia
abap/heap_area_total
rdisp/ROLL_SHM
rdisp/ROLL_MAXFS
rdisp/PG_SHM
rdisp/PG_MAXFS
rdisp/PG_LOCAL
ES/TABLE

  • Advice needed: The way to solve out of memory problem (or the way to work with big csv files)

    Hello:)
    I'm in trouble: I have a big csv file (over 5gb of web-analytics data) and my 64 bit excel (and 6gb ram)
    I cant load file to data model because of it's size. There is an error "out of memory" in power query. 
    This is the first time when I encountered such a problem.
    What options do I have to work with such a file? To increase memory in my computer? Would it solve the problem? How much do I need to work with 6gb csv? 
    Or may be I can upload my data somewhere to azure and work with it there? 
    So the problem - is there any way to deal with big files using power query? Or I need to become a developer and learn sql or other languages? 
    Thanks in advance.
    Max

    Hi Miguel!
    Thanks for your answer. 
    I've tried to load this file on virtual pc from azure cloud with this config:
    I have increased memory limit in power query settings:
    And still, the proble is the same:

  • JPA @Lob annotation and memory problem

    Hi.
    Is there any way to overcome the memory problem with @Lob types?
    FetchType.LAZY means lazy as it spelled. Am I right?
    And it doesn't mean any stream handling of big sized lobs. For lobs are so big that my physical memory can't hold it.
    @Entity public class Parent implements Serializable {
        @Lob private byte[] big; // what can I do if it is to big to hold in memory?
    }Is there any standard way for this problem?
    I found that openejb serves *@Persistent* annotation for InputStream/Reader for this purpose.
    But I want to know if there is another way for more portability.
    You know what?
    I heard from a JPA spec guy that this problem (maybe it's not a problem) won't even be considered in next version. (2.0?)
    How horrible...
    Is it can be a good think that split the Lob column into a OneToMany children?
    This is the best output, for now, from my head.
    @Entity public class Parent implements Serializable {
        @OneToMany private Collection<Child> children;
    @Entity public class Child implements Serializable {
        @Lob private byte[] chopped; // small enough to fit into memory
    }

    If the Lob is too big for your memory, then you are best off handling whatever processing you need to do on it through raw JDBC. If your only interested on the first n bytes, then you could probably map to something like this using a view the truncate the lob, and map your class to the view instead of the table.
    You should also be able to define your variable as Blob or Clob and get the locator directly. But the locator is tied to the connection, so will not be usable after the connection is returned to the pool. I'm not sure how such a lob could be model if it can't be read into memory, perhaps as some special JPA Lob type that can return a stream on the data by re-querying the lob from the db.
    What exactly to you want to do with the lob?

    Hi,
       I suppose you are trying to store some particular value in memory in one program and then retieve it in another.
    If so try using EXPORT data TO MEMORY ID 'ZC1'. and IMPORT data FROM MEMORY ID 'ZC1'.
    To use SET PARAMETER/GET PARAMETER the specified parameter name should be in table TPARA. Which I don't think is there in your case.
    Sample Code :
    Data declarations for the function codes to be transferred
    DATA : v_first  TYPE syucomm,
           v_second TYPE syucomm.
    CONSTANTS : c_memid TYPE char10 VALUE 'ZCCBPR1'.
    Move the function codes to the program varaibles
      v_first  = gv_bdt_fcode.
      v_second = sy-ucomm.
    Export the function codes to Memory ID
    EXPORT v_first
           v_second TO MEMORY ID c_memid.        "ZCCBPR1  --- Here you are sending the values to memory
    Then retrieve it.
    Retrieve the function codes from the Memory ID
      IMPORT v_first  TO v_fcode_1
             v_second TO v_fcode_2
      FROM MEMORY ID c_memid.                                   "ZCCBPR1
      FREE MEMORY ID c_memid.                                   "ZCCBPR1
    After reading the values from memory ID free them your problem should be solved.

  • Memory Problems with Adobe PDF iFilter for 64-bit

    In preparation to rebuild my Windows Search Index, I installed the Adobe PDF iFilter for 64-bit on my system (Vista Business 64).  When I finally rebuilt the index, I wasn't too surprised by what I saw happen, namely, the SearchFilter.exe process would kick in whenever I wasn't using the system and just eat RAM.  One time I turned it on and it had allocated over 4,000 MB (and my system only has 4,030 MB available) so of course it was forcing all the other processes to hard fault (ie. everything was moving like molasses--for example, it took 20 minutes to put the thing to sleep).  But I just let it do it's work, figuring that perhaps this was to be expected relative to the small library of PDF's that I've accumulated on my computer, ranging from LaTeX generated text files, to containers for hi-res scans.  So, after a day and a half of basically not using my laptop, everything finally calmed down and I enjoyed the benefits of searching the content of my library from the Windows Start menu--for a short while.
    However, to my dismay I've encountered the problem that this freezing of my computer would now occur after everytime I download a new PDF (in this particular case they were Google Books scans) and then left the computer to idle.  Again, the SearchFilter.exe would allocate all of my RAM for itself and just push everything else onto the Virtual RAM, which means the SLOWEST possibly fetching you can get.  I had to uninstall as this was making my computer unusable for 15-30 minutes after each idle. Everything is back in working order without the iFilter, but I would like to know if anyone has reported such problems on x64 systems.  Obviously, I will also report the problem to Microsoft, since the search engine should certainly have the precaution to handle such memory problems.   However, it is a problem that is created by the Adobe PDF iFilter interacting with the Windows Search engine.

    Hello,
    We believe we have figured this out.  It looks like it has to do with the length of the default folder location for the Adobe iFilter.
    I was able to reproduce the issue and the following resolved it for me.  See if this resolves it for you all as well.
    Here is how to get Adobe Version 11 PDF filter to work.
     1 . If you haven’t already, run the following in SQL Server:
    Sp_fulltext_service ‘Load_os_resources’, 1
    Go
    --you might also need to run: 
    sp_fulltext_service ‘Verify_signature’,0  --This is used to validate trusted iFilters. 0 disables it. So use with caution.
    --go
    2. Stop SQL Server.  (Make sure FDHost.exe stops)
    3.  
    Uninstall the Adobe ifilter (because it defaulted to having spaces or the folder name is too long).
    4.  
    Reinstall the Adobe iFilter and when it prompts for where to install it, change it to: C:\Program Files\Adobe\PDFiFilter
    5.  Once the installation finishes, go the computer’s Environment variables. Add the following to the PATH.
    C:\Program Files\Adobe\PDFiFilter\BIN
    NOTE: it must include the BIN folder
    NOTE: If you had the OLD location that included spaces, remove it from the path environment variable.
    6. Start SQL Server
    7.  IF you had an existing Full-text index on PDFs, drop the full-text index and recreate it.
    8. You should now get results when you run sys.dm_fts_index_keywords('db','tblname')  --Note: Change db to be the actual database name and tblname to be the actual table name.
     Give this a try and see if this fixes yours. 
    Sincerely,
    Rob Beene, MSFT

  • Memory problems with PreparedStatements

    Driver: 9.0.1 JDBC Thin
    I am having memory problems using "PreparedStatement" via jdbc.
    After profiling our application, we found that a large number oracle.jdbc.ttc7.TTCItem objects were being created, but not released, even though we were "closing" the ResultSets of a prepared statements.
    Tracing through the application, it appears that most of these TTCItem objects are created when the statement is executed (not when prepared), therefore I would have assumed that they would be released when the ResultSet is close, but this does not seem to be the case.
    We tend to have a large number of PreparedStatement objects in use (over 100, most with closed ResultSets) and find that our application is using huge amounts of memory when compared to using the same code, but closing the PreparedStatement at the same time as closing the ResultSet.
    Has anyone else found similar problems? If so, does anyone have a work-around or know if this is something that Oracle is looking at fixing?
    Thanks

    From your mail, it is not very clear:
    a) whether your session is an HTTPSession or an application defined
    session.
    b) What is meant by saying: JSP/Servlet is growing.
    However, some pointers:
    a) Are there any timeouts associated with session.
    b) Try to profile your code to see what is causing the memory leak.
    c) Are there references to stale data in your application code.

  • Dual Channel memory problems on Neo 875P

    I am having considerable trouble getting the NEO 875P to work with dual channel DDR400 DIMMs. I have two Kingston KVR400X64C25 DDR400 256MB memory modules, each of which works correctly by itself. However, once I move one
    of the modules to channel B, I cannot boot my operating system (currently Windows XP.) The problem also occurs in Windows 2000, which I also have on the system. I receive blue screen errors that indicate paging/memory problems. I have upgraded my BIOS to the latest version (1.3)* in the hope that it would solve my problems, but it has not. The POST screen detects that there is 512MB of memory working in Dual Channel mode, but even when it does get through the O/S booting process (rarely), it crashes within minutes. Putting just one of the chips in makes the system perfectly stable. If anyone has any information, please let me know!
    Thanks,
    Jim Keller

    * My board was dead after trying to flash the 1.3 BIOS, but after about 10 attempts of using CTRL+HOME method to recover the BIOS, it finally worked with version 1.0. I then re-flashed with 1.3, and it rebooted fine. Are there any updates about all of the problems with v1.3 ?

    >I can only answer based on what I've read on this forum
    I figured as much, I was just wondering if you knew whether MSI themselves frequents the forums or answers emails sufficiently.
    I've had an interesting development though. I stumbled upon Tom's Hardware Guide's article about 875P motherboards at http://www17.tomshardware.com/motherboard/20030519/i875p-01.html
    They mentioned that they needed to increase the memory voltage from 2.5 to 2.6 in the BIOS to get some memory modules to work. I did this, and for the first time, I am running in Dual channel DDR mode. However, the article also mentions that "the system does not run completely stably", so I guess I'll have to wait and see if it crashes again. However, I'm far enough beyond the XP splash screen to post this message, so I guess we're getting somewhere!

  • MS-6380 Memory Problem

    I have a MS-6380E with the latest BIOS and chipset drivers. Athlon 1.5 Ghz processor, Geo4 Ti series card with 64MB ram and latest drivers and an SBLive Platinum 5.1 card, with the latest drivers. Windows XP Pro is the operating system. The system has 2 PC2100 256MB sticks of DDR ram on the board. This past weekend I tried to install a 3rd chip, PC2100 512MB chip to bring the system up to a Gig of ram. The system would reboot immediatly upon logging into Windows. I took the memory back and exchanged it for another. Installed it with similar results. I tried all three slots with the new memory and the two existing. No, I didn't try the new memory by itself. I finally go it to appear stable for a little bit but I also play Dark Age of Camelot and the latest symptoms were that the system would kick me back to the desktop as soon as I got to the initial "connecting" screen in Dark Age. I also had other odd behaviour with the additional ram installed like my modem taking longer to validate my connection. When I went back to the pre-existing configuration 512MB total, everything would stabilize. The DDR brand was Centron, I know it's not the same manufacturor as my other two sticks but I don't recall the brand on those.  Also, just in case you needed to know Dark Age of Camelot is an MMORPG. I checked their tech section and nothing on this problem and their game. I've since returned the memory and have resigned to maxing out at 512MB tho the system specs say I can go to 3GB. I really like this board but am frustrated at the memory problem.

But problem is still there. when i check the phone memory it indicates that i have other files of 42mb installed and using phone memory. however i am unable to check what other files are installed or classfied as other files. Can you please assist me so i can know what these other files consist of or where they are located.

    Hi Thetao,
    I typed a more extensive reaction before, but it got lost when I pressed "post". Therefore I just respond to the main points that you mentioned (and some I found out myself).
    Strange: I can't find the 40 MB Maximum User Storage on the Nokia website anymore (nor the 75 MB). But it sounds very familiar to me. It looks to me as if they removed this from the phone specs, also of other Smartphones by the way.
    Yesterday, I deleted some small apps that I don't use (anymore) such as InternetRadio and I also removed Nokia email. Although the apps were below 2 MB together, this freed up over 7 MB of Phone memory (24 MB free now)! I think there were still some old emails stored in C: which I couldn't delete any other way. This helped me a great deal already but I tried your suggestions as well.
    1. No map data or CITIES folder on C: 2. Switched messages memory to phone (and phone to offline mode) and I did indeed find a forgotten email account with 30 email messages. Not much but I had 24,7 MB free after that. Of course, I put messages memory back to the memorycard. 3. Used the free edition of Y-Browser to manually delete the cache folder. Not much data in that, but 25,1 MB free after that. Nice tool, with which you can reach folders that normally stay hidden! Used YBrowser to search all C: for files over 300 kB. Only 2 files: boot_space.txt in C:\ (500 kB, contains only the X repeatedly as far as I see, but is probably essential for the operating system) and C:\resource\python25\pyton25.zip (1 MB). It looks like an installation package, but I'm not sure if I can delete it. By the way: YBrowser hasn't made a shortcut in one of the menus. Only way that I found to start it was to look for it using the Phone's search function. Is there a way to make this shortcut myself?
    4. Yes I did. No Images folder on C: anymore, nor other big files (see point 3)
    5. I use Bluetooth for file transfer sometimes, mainly for installation files (such as YBrowser.sis, but I did this one via USB-cable). However, no big files are left on C: so I don't think I have this problem.
    6. I tried to delete Nokia Chat yesterday as well (with the other apps), but it won't be uninstalled the normal way as it says "Uninstall cancelled" (not sure about the exact translation since my phone 'speaks' Dutch) Do you know if there's another way to get rid of this 3 MB app that I don't use at all?
    I think I may have found an explanation and a solution for the memory problem while navigating. You mentioned the "memory in use" in the map settings. Above that option there's a slide bar for the % of memory that the navigation can use. Standard is 70%. I always thought this was about storage memory on (in my case) the memorycard. Another topic mentioned that this the working memory (so the RAM) that the navigation may use. Setting it to 70% means there's only 30% left for other apps that run in the background. The other topic states that this is nog enough so the slider should be set to for instance 30% for navigation leaving 70% free for "the phone". From behind my computer, navigation seems much more stable. I'll try this setting in my car soon and let you know how it works.
    Thanks a lot for thinking along with me so far! There's already 25,1 MB of space, which is great since it was only 7 MB last Sunday. And navigation looks more stable. I'd appreciate if you have some more answers to my latest questions, but if not I think my phone will work a lot better already!
    Regards, Paul

  • Memory problem with jdk/jre 1.1.8

    My name is BERGMANN Yannick.
    I'm working for IRM in Li?ge and we developped an application (user interface for an industrial measurement system) in Java (JDK/JRE version : 1.1.8).
    We have a big memory problem with this application :
    - This user interface is running on a WINDOWS NT PC with 128MB.
    - This is the command to lanch our application :
    C:\Program Files\JavaSoft\JRE\1.1\bin\jrew.exe" -ms32m -mx32m -cp "\Program Files\HMI\HMI.zip;\Velocis\Add_On\Jdbc\raima.jar;\Program Files\Swing-1.1.1\swingall.jar" be.irm.hmi.kernel.HMI -t15 -d"Velocis rdstcp" -newdb -mf1m -mr20
    - When our application is running, everything seems to be OK in memory for it. The garbage collector seems to work properly and our application has always at least 5MB free memory (We use the java instruction "Runtime.getRuntime().freeMemory()" to know this).
    - But when we look in the "Windows NT task manager" for the "jrew" application, the memory increases ALWAYS.
    - After 5 days our application is completely frozen and blocked ...???
    - here is a memory map of our Windows NT PC :
         "jre.exe"     "commit total"     "commit limit"     "commit peak"     "physical total"     "physical available"     "physical file cache"

    Monday     111600     209060     228548     209148     130484     5184     3484     
    Have you any idea of what is happening with "jrew" in memory ?
    We have had this problem for six month and we are totaly out of idea.
    If you can give us any idea, we'll appreciate a lot.
    Thanks in advance,

    We had a memory problem with a swing applet in our company. The major reason for this was that we added new components in a JTree and removed them later again, and the components we removed were never garbage collected. This was because with these components we added different listeners, and we didn't remove the listeners after we didn't need the components anymore. After we corrected this, the components where garbage collected.
    Perhaps it's a similar problem you have, or I have no idea. Check that you remove actionlisteners, mouselisteners etc from components you want to be garbage collected.
    You could also test your application with OptimizeIt to see what objects you create and how many you get of them over time: http://www.vmgear.com

  • Memory problem with 5330 XpressMusic

    Hi,
    I seem to have a memory problem with my 5330, I have a 1Gb micro disc installed. My son sent me a photo from his phone, when it arrived I got a warning on the scren that 'there is not enough memory to receive messages', I have tried to delete as much as I can, a lot tells me I can't delete it, but I still get the same warning. This warnig shows up each time I switch on the phone. How can I get myself more space? Can I move things from the phone memory to the memory card?

    Are you sure you're using a 5330 XpressMusic? Or is it a 5320 XpressMusic? The former is yet to be released, AFAIK.
    Assuming that you are using a 5320, try these steps:
    -> Move all photos, music, videos stored in the phone memory to the memory card. You can use the built-in File Manager to accomplish this.
    -> Delete all files that you would've received via bluetooth, present in your Inbox. You can save them to the mass storage.
    -> Clear the browser cache.
    -> Clear the Sent Items folder.
    -> Make sure you don't have too many messages in your inbox.
    Hope this helps

  • Memory problem with ITS

    Hello friends,
    we are having memory problem with integrated ITS.. on one application server all memory of ITS is getting exhausted. We think few users take lots of memory and it never gets released.
    I checked Note 742048 - Integrated ITS, memory requirement in application server but parameters looks ok. Sometime, when i kill a user session in SM04, some part of memory was released. However i am not able to find which sessions are taking max memory as i do not see any workproess active in SM50.
    in SITSPMON :
    Memory Consumption: Overview
    Sessions:     27      24,710,431 Bytes       915,201 Bytes/Session       2,433,8

    thanks

    and what is 2463 is line : USER(user ID) 001(Client) 2463(??) Session Memory 1,955,757 938,597 7,574 723 as this is not a work process ID.]
    Basically i am trying to correlate ITS session with SM04 Session of user.
