This may or may have nothing to do with the problem - my question why sqlite tries to close the database?

Thanks for your help.

1. this difficulty could certainly be the root of your problems. There were several threads/processes open an existing SQL database at the same time.

2. Yes, it made for a problem where deleting a table could result in the process of becoming deadlocked.

  • problem of memory sql toolkit

    Hello

    We use CVI 2012 and SQL Toolkit 2.2. Once a minute, we're looking a record for a special SQL database and we update the data in this leaflet. After update, let's close the database. Whenever we do this procedure that we see in the Task Manager which increases the memory needs of our program.

    After a few minutes (20-30) we get an error message memory.

    Anyone know if there is a problem to know or can someone help us?

    Thanks in advance

    Oliver

    Here is a part of the code:

    //
    hdbc = DBConnect (DATABASE_STRING);

    //
    HSQL = DBActivateSQL (hdbc, "' SELECT * FROM 'data_l01'" ");

    //
    RW = DBBindColChar (hsql, SQL_DATE, 32, cDB_Date, & iDB_Date_State, "");

    Insert the record into the database
    RW = DBPutRecord (hsql);

    //
    RW = DBDeactivateSQL (hsql);

    //
    RW = DBDisconnect (hdbc);

    Hi Oliver,.

    To read your code, I understand that you open a connection to the database for each update that you want to run.

    Usually I would advice you to open the database connection to the start once this reference until the program is closed instead of open every time.

    This could potentially solve your problem.

    Please let me know if that solves your problem.

  • How to fix a corrupt Sony Memory Stick Pro Duo

    Hello, I have a problem with my Memory Stick. I'm sure that it's corrupt, because I get the usual "No. Memory Stick detected" messages.

    The problem here is that I need to know how to solve this problem by using Windows. I have a memory stick reader that I consider using a USB port and whenever I try to open the location, the computer either locks up until I have remove the stick, or he says no disc inserted in the drive. Once, I managed to get my other computer to say "Device must be formatted before use", but after clicking the format, he said that couldn't be. It seems that Windows just hate my Memory Stick but I really want to solve this problem.

    If someone think of an answer, please answer. I'll give you more information if necessary.

    Insert the disc, but do not attempt to access or open.  Go to start / Control Panel / administrative tools / computer management / disk management.  The disc appear?  If Yes, go to the disc and try to format it using disk management features (I guess since you've already tried to format that it contains no data to record).  If it does not, there is probably a problem with the memory stick (or the USB port - try another port) as only corruption would not prevent from being recognized as valid a drive.

    Let us know what happens.

    I hope this helps.

    Good luck!

    Hello

    first of all, I have good malware scanner and then pull up to your CMD prompt and run in ADMINISTRATOR mode... scan files

    so it will look like this on the fast line

    sfc/scannow

    If it detects the wrong files it will try and fix...

    Once that is done and all seems good... Run windows update... and make sure that all THE DRIVERS are updated... There was an update in last 6-8 wks is hitting all the settings, but MS does not move fast on this...

    Make sure you restart after every high driver you do as she needs... otherwise nothing will change... go read the forums for malware on bleeping computer dot com and tech guy... you will see a lot of us dealing with this and you will see bugs... these forums are free

    Good luck

  • Corruption of memory NVRAM Possible Z580

    Hi guys ~!

    Since the last time I posted here, I got my Wi - Fi adapter and cable replaced LCD, my warranty is far beyond being expired and... Well, I had a new problem here.

    Some background first:

    After realizing that lenovo support in Poland is as - somehow totally new to be terrible, useless and cause more problems than it's worth (finally), I ended up approaching my laptop with my own skills in computer repair - parts is not free but at least I'm getting somewhere, right?

    September 12, 2014, I flashed my BIOS to remove the white list and got an adapter Intel Wi - Fi (5100 AGN) as a replacement for my broken Atheros who becomes completely useless at this point, and all I could do was throw it.

    After flashing the BIOS, I noticed that the entry of start menu the menu of Novo pointed to the configuration of the BIOS, while everything else was basically just to boot the os of the 1st player. I do not much since I always access to the BIOS, so that I can start all the cool stuff I had on my USB with no problems.

    I tried to update my Windows 10 for new construction, April 11. The process seemed to get stuck at some point given - I managed to read a book while waiting then... you know. So I tried force-restart of my camera and...

    Well...

    * beep *.

    Question:

    I can't access BIOS Setup by any means, or the Start Menu. I'm with Secure Boot UEFI enabled mode, about default settings. Remove the HARD drive got stuck on the blank screen. Of course, I can boot any player USB in this way (it's how I restored my Windows 10, I just did a clean install of USB). I wish I had this two guys back without replacing the motherboard if.

    What I tried:

    I used efibootmgr to check that if the UEFI entries are still there-, so they're doing efibootmgr magic will not help.

    I tried to do a BIOS update using a lenovo site utility, but I got an error checking - I think maybe it's because I got my BIOS modded-whitelist.

    I tried this weird thing with removal of all sources of power and pressing the button for 30 seconds, which probably eliminated the CMOS - no effect.

    I suspect corruption NVRAM, based on what I found on the Internet - although it occurs mainly on Samsung devices (perhaps, Phoenix BIOS, this is not a bad trail).

    And please, don't suggest me to contact lenovo support, simply read the entire post first - my warranty has already expired, I cancelled in waaays maaanyyy so there is no way that they could help me and I think that buying a new motherboard and replacement of the stuff myself cost me lenovo doing much less do it for me - even though I don't want to Since I can live with this problem, really.

    Basically, I answer to myself (STILL ALOOONEEE), but in any case, I thought that this could be useful for someone.

    Remove the battery CMOS did the trick, I can now access the BIOS Setup. List of entries is always a little weird, but I think this must be just a bug in this mod white list, not that it never worried me anyway.

  • Determination of needs memory to SQL Server

    Hi all

    I've looked everywhere and can't seem to find the answer to this question.  And it seems strange because I really can't believe I'd be the first person in this situation.

    The situation:

    I pull some data on about 30 servers perfmon to size a new farm to run some of our external facing infrastructure.  I get good data most of the boxes (ui, search, intermediate level, etc.) but not the SQL servers.  Regardless of the load on the server, SQL seems to devour almost all available memory.  Read about managing memory SQL, it is not surprising that he would show the way in perfom and/or the Task Manager, but I need to get a handle on the amount of memory, these servers will need to function properly.

    I know that there is much more to the issue of performance, but a SQL Server in particular has 32 GB of physical memory and SQL is actively filling 30 of it.  It would make a horrible candidate (like less because our host record and consolidation target ratios) for virtual server.  That said, I like the impression that this server might work on much less and uses this 30G because he can.

    There are people who would say "Start with 4 G, test, and add more than necessary".  Unfortunately, this is not really an option for us given the timeline and the visibility of the migration.

    Thanks in advance to anyone who can provide assistance here!

    -Brent

    Personally I start with 1 GB and work toward the top, but this depends on how active do you think that the server is.  If you think its quite busy then try using 2 GB for the operating system and give 1.5 GB to SQL and see how it behaves.

    Unfortunately, SQL will use given to her in the SQL Manager properties before you begin to re - use all available memory.

    The only way to really tell is to determine if your server is under memory pressure and adjust accordingly.  Unfortunately, this means start low and going back as things are going to hell.

    This will help to see if your server knows the memory pressure

    http://www.4penny.NET/SQL-Server-Troublshooting.aspx

    Memory

    • Memory: Available bytes

    • Memory: Pages/sec reads

    • Process: Working together: sqlserver

    • SQL Server: Buffer Manager: Buffer Cache Hit Ratio

    • SQL Server: Memory Manager: Total memory of the server (KB)

    The memory: available bytes indicates the amount of physical memory, in bytes.

    immediately available for allocation to a process or for system use. It is a memory

    not currently in use by the system.

    The memory: pages/sec reads shows the rate, in incidents per second, at which the

    disk was read to resolve hard page faults. This counter indicates the number of read operations, without

    with regard to the number of pages retrieved in each operation. Hard page faults occur when a process

    fact refers to a virtual memory page that must be retrieved from disk because it is not in his

    working set or elsewhere in physical memory. This counter is a primary indicator for types

    defects that cause delays throughout the system.

    A low number of available bytes indicates that there may be not enough memory available;

    or processes, including SQL Server, may not be free memory. A high number of faults Pages/sec

    indicate excessive paging. A more in-depth look at individual instances of process: Page

    Defects/s, to see if the SQL Server process, for example, has an excessive paging can be

    necessary. A low rate of defects of Pages/sec (usually 5 to 10 per second) is normal, as the

    operating system will continue to make a home on the range of work.

    Ideally, we'd like for SQL Server to be the only application on the server and with most of

    the memory in the box. Add memory to a server and configure SQL Server to use is

    beyond the scope of this article, but the more, the better.

    The process: working together: sqlserver instance indicates the amount of memory that SQL Server

    use, in bytes. If the number is always less than the amount of SQL Server is configured

    for use by the MIN SERVER MEMORY and MAX SERVER MEMORY options, and then SQL Server is

    configured for too much memory. Otherwise, you may have to increase the RAM and MAX SERVER MEMORY.

    Buffer Cache Hit Ratio should be constantly greater than 90. This indicates that the

    data provided 90 per cent of requests for data cache. If this value is always

    low, it is a very good indicator that needs more memory to SQL Server. If it is available

    Bytes is low, which means that we should add more RAM.

    If the total memory of the server for SQL Server is always higher than the total memory of the server,

    It indicates that there is not enough RAM. This counter is in KB, as opposed to bytes for the process: working together: sqlserver

  • ENVY 17 j - 153 cl Notebook: critical structure Corruption

    I have a HP ENVY 17 TS j - 153 cl laptop which has a BSOD problem. Last week trying to change some settings under settings on the touch screen PC, he told me there is a mistake and make an update to fix the problem. Unfortunately, I did as described and lost all my programs and settings and I am now in the process of reinstalling the software and in the reconstruction of my computer. And even now with a computer newly refreshed, who must have just a basic setup I get critical errors corrupt Structure every 20 to 60 minutes. I updated all my drivers and disconnected all USB external drives, but keep however to get the error. I have many minidump files and I was wondering if there is someone or somewhere I could send them to find out what crashes my computer. It's only a little over a year and I would like to continue to use HP computers in my company. As a computer consultant, I am a little worried that this problem has arisen on the mine and other HP systems that I usually recommend HP computers to my clients. Will you please help me solve this problem, so I can continue to use HP in good faith. And I have the chance of it not down again while that detachment.

    Thanks for the reply. Here is the screen after entering the first Dism command:

    C:\Windows > Dism / Online/Cleanup-Image /CheckHealth

    The operation completed successfully.

    After the second command line entry, the screen shows a list of the '20% ' and then seemed to get stuck right there, so I decided to cancel the command window.

    Then I used the program "Crashed" who gave me this analysis of my BSOD minidump files:

    This could be a case of corruption of memory. The corruption of memory more often happens because of software errors in the defective drivers buggy, not because of RAM modules.
    The accident took place in the Windows kernel. Maybe this problem is caused by another driver who cannot be identified at this time.

    So I've updated all my moments of three or four and also disconnected drivers all readers usb and other devices that might interfere with my computer, but still had no luck avoiding the BSOD. Also discovered that install updates of Windows my computer still aggravated and put me in the cycle "restart" or "repair" and unable still log on to windows. Finally got to a screen where I could run a restore point and already a before update and finally could reopen a session. As a last resort and I saw a message from MS to download the new http://www.duplexsecure.com/en/downloads SPTD driver and it is now 24 hours without crashing! I can not install Microsoft

    For Windows 8.1 update for x 64-based Systems (KB2990967) or

    Update 8.1 Windows for x 64 systems (KB2919355) message to without my system showing me the repair screen and cannot start, but it's a problem for another day.

    I highly recommend the new SPTD driver as a fix for the problem of Corruption of essential Structure and if anyone has any ideas as to why I can't install the Windows updates I would appreciate the help as I'm fresh ideas.

  • BSOD an attempt was made to write to readonly memory

    My computer went nuts and crashed last night. I have no idea what the issue is, I get error blue screen 'attempt was made to write to readonly memory'... sometimes. My anti-virus 'blocked a threat' a few minutes before the accident, so I don't know if it could be the associated virus. The computer hangs at each attempt to start it, System Restore and startup repair were not helpful either. Said Startup Repair could not fix the problem, and the system restore said he succeeded... but always crashing. I was able to do start in safe mode only (networking) off and recover the files of emptying and sys info

    But I have no idea what to do with this information.

    These accidents were related to the corruption of memory (probably caused by a driver).

    Run these two tests to check your memory and find which driver is causing the problem.  Launch auditor.  You don't need to run memtest again unless the auditor is not the cause, or you want to.

    If you are overclocking anything reset by default before running these tests.

    • 0 x 80000003: STATUS_BREAKPOINT indicates a breakpoint or ASSERTION was met when no kernel debugger was attached to the system.

    • 0xc0000005: STATUS_ACCESS_VIOLATION indicates a memory access violation has occurred.

    For a complete list of exception codes, see the Ntstatus.h file located in theinc directory
    the Microsoft Windows Driver Kit (WDK).

    Solve the problem

    If you do not have to debug this problem, you must use certain basic troubleshooting techniques.

    • Make sure you have enough disk space.
    • If a driver is identified in the bug check message, disable the driver or check with the
    • Reference of the manufacturer for driver updates.
    • Try changing video cards.
    • Check with your hardware vendor for updates to the BIOS.
    • Disable the BIOS memory options such as implementing caching or shading.

    If you plan to debug this problem, you may find it difficult to get a stack trace. Parameter 2
    (the address of the exception) must identify the driver or function that caused the problem.

    If the exception code 0 x 80000003 occurs, a hard-coded breakpoint or assertion was hit, but the system
    has been launched with the /nodebug. switch. This problem should occur infrequently. If it occurs repeatedly,
    Make sure that a kernel debugger is connected and the system is booted with the Switch/DEBUG .

    In case of exception code 0 x 80000002, the trap frame provides additional information.

    If you do not know the specific cause of the exception, consider the following questions:

    • Hardware incompatibility. Make sure all new hardware that is installed is listed in the
    • List of Microsoft Windows Marketplace tested products.
    • Service driver or defective peripheral system. A service driver or defective peripheral system can be
    • responsible for this error. Hardware problems, such as the incompatibilities of the BIOS, memory, conflicts
    • and IRQ conflicts can also generate this error.

    If a driver is listed by name in the bug check message, disable or remove that driver. Disable
    or remove drivers or services that have been recently added. If the error occurs during startup
    sequence and the system partition is formatted with the NTFS file system, you may be able to use safe
    Mode to rename or to delete the faulty driver. If the driver is used as part of the system startup procedure
    in Safe Mode, you must start the computer by using the Recovery Console to access the file.

    If the problem is associated with Win32k.sys, the source of the error may be a third remote
    control program. If this software is installed, you can remove the boot of the computer service
    by using the Recovery Console, and then by removing the offending system service file.

    Check the system log in Event Viewer for additional error messages that might help identify the
    device or the driver that generated the bug check 0x7E.

    You can also disable memory cache BIOS may try to resolve the error. You should also
    Run the diagnostics of material, especially the scanner memory, which provides the manufacturer of the system.
    For more information about these procedures, see the manual of your computer.

    The error that generates this message may occur after the first reboot during Windows Setup, or
    Once the installation is complete. A possible cause of the error is lack of disk space for installation and system
    BIOS incompatibilities. For problems during the installation of Windows that are associated with the absence of disc
    space, reduce the number of files on the disk drive hard target. Find and delete any temporary
    the files that you do not have to have files hidden Internet, backup application and.chkfiles files that
    contain fragments of file saved to disk scans. You can also use another hard drive with more drive
    free space for the installation. You can solve the problems of BIOS by upgrading the version of the system BIOS.

    BCCode: 50 0 x 00000050

    References to Vista also apply to Windows 7.

    Have you recently added any hardware? Have you updated any drivers just before this started? (Check
    Panel configuration-updates of Windows to see if all drivers have been updated it there all the time it started)
    Main likely culprits are video driver, other great drivers, memory and antivirus/antispyware/security
    products could be at fault as well as reader questions.

    Use the troubleshooter below and refer to the following message to drivers and memory when you get to
    These sections and then back to the resolution of the problems according to the needs.

    BCCode: 50 0 x 00000050

    Cause

    The BCCode 50 usually occurs after the installation of faulty hardware, or in case of failure
    hardware installed (usually associated with a faulty RAM, be it the main memory, L2 RAM cache memory, or)
    Video RAM).

    Another common cause is a defective system service installation.

    Antivirus software can also trigger this error, as can a corrupted NTFS volume.

    Solve the problem

    Solve a defective hardware problem: If the material has been added to the system recently,
    Remove to see if the error recurs. If existing hardware has failed, remove or replace
    the defective component. You must run the diagnostics of material provided by the manufacturer of the system.
    For more information about these procedures, see the manual of your computer.

    Fix a defective system service: Disable the service and confirm that this
    resolves the error. If so, contact the manufacturer of the service on a possible system
    Update. If the error occurs during the system startup, restart your computer, and press F8 to
    character mode menu that displays the choice of operating system. As a result
    Windows Advanced Options, select last good known Configuration option menu.
    This option is most effective when a pilot or a service is added at a time.

    Solve a problem of antivirus software: Disable the program and confirm that this fixes
    the error. If this is the case, contact the manufacturer of the program about a possible update.

    Fix a corrupted NTFS volume:  Run Chkdsk /f /r to detect and repair disk
    errors. You must reboot the system before the start of the analysis of disk on a system partition. If
    the hard drive is SCSI, check for problems between the SCSI controller and the disk.

    Finally, check the system log in Event Viewer for additional error messages that might help
    identify the device or driver that generated the error. Disable the cache in memory of the BIOS
    could also resolve it.

To find contact information for Microsoft or the manufacturer of your computer, Contact Support.

    If you have experience with computers and try to recover from this error, follow the steps in the Microsoft article solution STOP (blue screen) errors in Windows.

    The following actions could prevent a mistake like this does not happen:

    1. Download and install updates for your computer from Windows Update device drivers.
    2. Scan your computer for computer viruses.
    3. Check your hard drive for errors.

  • Smartphones blackBerry media card is always corrupted after formatting with my Blackberry!

    Whenever I insert a new memory in my BlackBerry it says that the card is not formatted. I format the press card and a message appears that the media card inserted contains errors.

    I tried everything to fix my problem. Search for and repaired errors on the form of media with my PC. Also on my BlackBerry. Format media on my PC and Blackberry maps. The message keeps popping up. I tried 5 new cards from SanDisk.

    I suspect that my BlackBerry is corrupting the memory/media. If so, what can I do about it?

    Information on blackBerry: 7.1 Bundle 1319 (v7.1.0.398, platform 9.49.0.31)

    Hello and welcome to the community!

    From what you describe, I assume the same problem... However, I also deduce that the problem is hardware (e.g., material of read/write of the physical card on the device) rather than software/OS. Therefore, there are material assessment and repair, which of course cannot be done internet remotely. I recommend you find a store (for you) with a qualified material BB technician and ask them to give you a correct assessment and estimate.

    Good luck!

    These accidents were caused by the corruption of memory (probably a driver).  Run these two tests to check your memory and find which driver is causing the problem.

    * Don't forget to download any other DMP files (especially those running auditor)

    * If you are overclocking reset all default before running these tests.
    In other words STOP!   If you don't know what it means that you're probably not

    1 - Memtest.
    * Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. http://www.memtest.org
    * Boot from the CD and let it run at least 5 or 6 passes.
    * Don't forget, anytime Memtest reports errors, it can be bad RAM or a bad motherboard slot.
    * Test the sticks individually and if you find a good, test it in all slots.

    Any error is indicative of a memory problem.
    If a well-known stick fails in a slot of motherboard, it's probably the slot.


    2. Driver Verifier

    Using Driver Verifier is a dubious proposition. Most of the time it will crash and it will tell you what is the driver.

    * But sometimes it will crash and will not tell you the driver.
    * At other times it will crash until you can connect to Windows. If you can't mode without failure, then you will have to resort to editing the registry offline to disable driver verifier.
    * I would suggest that you first back up your data and make sure that you have access to another computer so you can contact us in case of problems.
    * Then do a system restore point (so you can restore the system using the functionality of Vista/Win7 Startup Repair).

    Here is the procedure:

    -Go to start and type "auditor" (without the quotes) and press enter
    -Select 'Create a custom settings (for code developers)' and click 'Next '.
    -Select "Select individual settings from the list complete" and click "Next".
    -Select the entire document except for "Low resource Simulation" and click "next".
    -Select "Select driver names from a list", then click "next".
    * Select all drivers that are NOT supplied by Microsoft and click on "Next".
    -On the next page, select "Finish".
    * Restart the system and wait as he crashed to blue screen.


    * Continue to use your system normally and if you know what are the causes of the crash, do it several times. The objective here is to get the system crash because Driver Verifier is stressing out the drivers. If it is not planted for you, then let it run for at least 36 hours of continuous operation.
    * If you are unable to Windows because it crashes too early, try safe mode.
    * If you can't mode without fail, try to use the system from the installation DVD restore to bring the system back to the previous point of restoration that you created.

  • How to find the sql queries executed in one day with the sql and runtime text

    Hi Experts,

    Please tell me the sql query to find out the queries executed on a particular day and the runtime and the sql text of the query.

    Please reply urgent.

    Thanks in advance

    Database instance 'A' may have run 100 SQL queries today.  As for the instance of database 'B' could have exploited queries SQL 1 million today.  Instance of database 'B' to 'keep' the 1 million SQL statements - in memory or on disk do you expect?  Of course not.  There the age or flush or invalidate memory SQL statements.  He can't keep them on the disk (imagine running a completely different set of 1.2million SQL statements tomorrow and 1.3 the next day).

    AWR and StatsPack can make counts the number of "n" top of the page ("n" default to 30) SQL statements which are still present in the cache of the library (not years, rinsed, invalidated) when a snapshot was taken.  They can't declare "all" SQL statements.

    To return to your needs.  WHY do you need all the SQL statements?  Or are there only certain operations specific SQL would you be interested?  Could they have been treated by allowing audit (for example, UPDATE and DELETE with EXTENDED verification instructions)?
