  • Strange behaviour when using connection pooling with proxy authentication

    All
    I have developed an ASP.NET 1.1 Web application that uses ODP.NET 9.2.0.4 accessing Oracle Database 8i (which is to be upgraded to 10g in the coming months). I have enabled connection pooling and implemented proxy authentication.
    I am observing a strange behaviour in the live environment. If two users (User 1 and User 2) are executing SQL statements at the same time (concurrent threads in IIS), the following is occurring:
    * User 1 opens a new connection, executes a SELECT statement, and closes this connection. The audit log, which uses the USER function, shows User 1 executed this statement.
    * User 2 opens the same connection (before it is released to the connection pool?), excutes an INSERT statement, and closes this connection. The audit log shows User 1, not User 2, executed this statement.
    Is this a known issue when using connection pooling with proxy authentication? I appreciate your help.
    Regards,
    Chris

    Hi Chris,
    I tried to reproduce your complaint, but was unable to. I didnt use auditting however, just a series of "select user from dual" with proxy authentication. You might want to see if you can put together a small complete testcase for this and open a sr with support.
    Cheers

    when i run function directly at SE37 .
    i found data.
    but when i use same function in program .
    system not found.

    help me please.

    http://www.quickfilepost.com/download.do?get=c974356a498b3a4d369aa0c50622e50b

    I know why U get empty data.
    In Program U should follow the rules:
    U'd better data a variant typed the function parameters's type.
    for example:
    in your program the parameter: stlal  = '1'
    U'd better like follow:
    Data l_stlal type STKO-STLAL
    l_stlal = '01'.  *Attention: '1' <> '01'.
    stlal  = l_stlal.
    in this way U may have less mistake
    and the parameter MTNRV
    U should use material convernt : "CONVERSION_EXIT_MATN1_INPUT" to change material into internal types before U put into function's parameter.
    why se37 has no problem? because In se37, the data you filled was be processed before use

  • Server 2012 R2 100% cpu usage when using search

    Hi all!
    We are experiencing issues with the built in search in WS 2012R2 (Win+Q). Upon starting to type, the explorer.exe process peaks and stays at 100% until typing is done and the search is complete. It also can't keep up with typing and hangs after
    a few keystrokes. We have done tests on 2012 R2, 2012 and 2008 R2 running as VMs with 1 cpu. The tests performed have been run on a host running only the test VM with underlying 2x8 core cpus, SSD, SAN storage and 256GB RAM. Also, we have tested
    both Hyper-V and VMware ESXi 5.0. We see that if we add another CPU to the guest it alleviates the keystroke lagging, but the explorer.exe still consumes 100% cpu.
    When the same tests are run on a physical machine (approx. same specs as the virtualization hosts) the cpu usage reaches 15-20% on one of the physical sockets (numa node). Totally negligible, but still a high number.
    We are afraid of service impact and are keen to know if anyone else is experiencing the same? Maybe someone has a fix?

    Hi TrondWH,
    Thanks for contacting Microsoft.
    Currently, would you please try cleaning boot the server and test how the issue goes. Cleaning boot can exclude some third-party application affect. Following are the detailed steps about clean boot:
    Log on to the computer by using an account that has administrator rights.
    Click Start, type msconfig.exe in the Start Search box, and then press ENTER to start the
         System Configuration Utility.
    On the General tab, click Selective Startup, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
    On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
    Click OK, Choose Don’t show this message again and then click Restart.
    Please check if the issue is still the same.
    Please let me know the result.
    Best regards,

  • Certificate error when using connection broker on Mac client

    We're using RD Connection Broker using IP address redirection for a couple of years now. Previously Mac client were using iTap RDP without any problems. Clients are connecting using a RD Gateway server.
    When trying to connect using the latest Microsoft remote desktop client (version 8.0.24255) a certificate warning is shown saying the IP-address doesn't match the name in the certificate. The client shoudn't match the IP address with the certificate but
    should match the farm name. The error occurs when the connection broker redirects the client to a server.
    Any help is appreciated

    My external display is a Samsung PX2370 connected to my MBP using an HDMI cable with a HDMI-to-miniDP adapter
    I first noticed this after the last EFI update several months back. At first I thought kernel_task eats up too much cpu cycles whenever an external display is attached, but it turns out this only happens when the external display is set to 1080p. When external display is set to 720p, kernel_task is pretty much normal (~5% cpu usage) but rises up to ~150% cpu usage once the external display is set to 1080p.
    kernel_task cpu usage is also with normal range when my MBP is connected to a Samsung LCD TV at 720p.
    Anyone having the same problem or know of any fix/workarounds?

    Seems like the problem persists when playing a 720p video on the external display set to 720p. To sum it up

  • [SOLVED] qemu-kvm high cpu usage when using pulseaudio alsa-plugin

    My Arch system is configured to use pulseaudio. When an application connects to the sound server it will use either a native pulseaudio driver, or the pulseaudio alsa-plugin if it using a alsa driver.
    qemu-kvm in 'extra' is not compiled with native pulseaudio support. When running guests with sound hardware support, qemu-kvm connects to the sound server using the pulseaudio alsa-plugin.
    The problem I'm seeing is high cpu usage on the Arch host even though cpu usage on the guest is low. Also, the guest is often unresponsive for a period of time when opening sound applications like the mixer or playing audio.
    My solution is to recompile qemu-kvm with native pulseaudio support. This eliminates the use of the pulseaudio alsa-plugin on the Arch host and fixes the above problems.
    An easy was to do this is run:
    yaourt -S qemu-kvm --build
    And edit the PKGBUILD changing the line:
    --audio-drv-list=alsa,sdl,oss,esd \
    To:
    --audio-drv-list=pa,alsa,sdl,oss,esd \
    Finish building and install. Don't forget to add yourself to the kvm group.

  • High cpu usage when using flash player

    Hi,
    Just updated to Mavericks and now I'm having very high cpu usage while watching streams using flash player.

    My program is running in a linux pc.
    And I use the commands
    "gcc -I"/java/include" -I"/java/include/linux" -o WClique.o -c WClique.c
    gcc -shared -o WClique.so WClique.o "
    to get the .so file.
    Then, I call the .so file from the original java file. However, it always returns the "unsatisfiedlinkerror". Note that I have used the correct library path and function name. I do not know what's wrong with it. Any one can help it?

    I have named the generated file as libWClique.so.

  • Spotify Queue Glitch when using Connect.

    I was not sure where to put this, because it seems to be an interaction between all of my devices, and I am not absolutely certain which device is causing the problem. ---Devices---
    Spotify app installed on my Computer (W7x64)and it is on my Nexus 5 (5.1?JellyBean)iPad2 (iOS8)Gramofon Spotify Player setup on my stereo as well.
    ---Problem--- I listen to album A on my phone.I stop playing music on my phone (android).
    I launch the Spotify player and start album B playing via connect to my Gramofon (or previously my iPad) hooked to my stereo.
    It plays the first track of album B, and then starts playing album A on the gramofon/iPad via connect, with no interaction to the phone.
    summary: Whatever I was listening to on my phone will over-ride any other connect session *repeatedly* until i kill the app in the phone.
    I usually have to go in and force-quit the app in Android but I'm not positive that *always* works, or just intermittently. This happens frequently. Like, evertim.
    I would appreciate some solace and perhaps a bug fix or something. Other than that I couldnt be more thrilled with Spotify, and this connect feature is absolutely lovely. Sorry if this post already exists, I did a cursory search but wasnt able to find a match. 

    So, I'm not sure what happened between yesterday and today, but it is playing my phone queue from my computer with no issues, but the song being displayed on my phone is not the one playing. I can live with that.
