ORACLE dispatcher process running high cpu (100%)

Hi:
I'm running Apex 4 on database Oracle 11g 11.2.0.2.0. The cpu consumption is really high after a while. Oracle Dispatcher process goes 100% cpu for very long time.
Anyone here had the same problem? I'm created more dispatchers to workaround this issue but the problem is not solved. At oracle support seams there's a bug about this issue 14106948, but no solution yet.
Anyone with same problem? Any solution?
Thanks
Ricardo

  • Mdworker process suddenly high CPU usage

    Hi All
    I've been running Mountain Lion since it was released, upgrading from Lion. I've never had a problem with mdworker until a few days ago when suddenly, the mdworker process started hitting 90% CPU on my iMac.
    I've disabled Spotlight, deleted the .Spotlight directories, rebooted the iMac, but each time mdworker . Prior to this, the iMac's CPU temperature was around 43C, with very little CPU usage, but now it is around 60C and 100% across the two cores. The only way to 'get back to normal' is to use :
    sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
    but of course Spotlight doesn't work at all.
    I've used 'sudo fs_usage -w -f filesys mdworker' but I can't see anything that mdworker is perhaps choking on.
    Does any have any ideas? I'm racking my brain to remember if I did anything different a few days back that might have caused this to happen, but apart from just normal email and web surfing, nothing else springs to mind.
    Help!

    This solved my questionRe: mdworker process suddenly high CPU usage     Nov 28, 2012 1:41 AM    (in response to antobal) 
    In my case it was the BritannicaBookmark.mdimporter that was a PowerPC mdimporter. But it was not in \library\spotlight but inBritannica 12.0/Ultimate Reference Suite.app/Contents/Library/Spotlight.
    You can see what spotlight plugin is choking on you by selecting the mdworker process in the Activity monitor and click on Open files and processes.
    Sounds helpful, but I don't see "Open files and processes" in Activity Monitor. If I click on inspect, I get a choice to "Sample" processes. I get a system log that is a bit beyond me.

    I was having the same problem, and a second level support person at Apple helped me solve the issue today:
    Look in the \library\spotlight folders both at your drive root level and your user folder. These folders contain spotlight plugins, with the extension .mdimporter. Some of those plugins, if defective, can make the Spotlight indexing processes to run continuously.
    Also sounds helpful, I found .mdimporter files in my system library, but nothing looked unusual. I didn't see a spotlight folder in my user library. I looked in application support and several other places. I used Onyx to repair permissions, rebuild spotlight index, clear caches etc, rebooted, it seems to be OK now.

  • SMON process consume High CPU in production setup.

    Hi,
    Recently we migrate our storage from IBM DS4700 to IBM v7000. on last Saturday from yesterday and today cpu almost 100 percent in peak hours.
    Right now our datafiles in SSD and archivelogs in SAS disk.
    Please suggest
    regards,
    Karthi.

    Hi Karthi,
    Which SMON process is consuming CPU ,I mean,Database SMON /ASM SMON if is in use.
    + Install and enable OSwatcher with atleast 30 seconds interval and monitor which process /what is causing high CPU.
    + If they are oracle processes ,then validate what are they doing at database level .
       Does it comes from any application code ,if so validate those sqls.
    + Install procwatcher to understand what are they doing .
    Refer::-----------
    ==============
    Procwatcher: Script to Monitor and Examine Oracle DB and Clusterware Processes (Doc ID 459694.1)
    + Then as per your environment get pstack/procstack of that process in 30 seconds interval for 3-4 times .
    If try to identify the issue ,if required please open service request with us.
    Regards,

  • Java Process with High CPU

    I have a java process running on HP-UX with a 1.4.2 JVM. This program is using some third-party code (quartz) to act as a batch scheduler similar to cron. When running in production, the process runs fine for several days and then starts maxing out the CPU. The server has 8 cpu's and the last time the problem occured, 4 of the cpu's were 100% in use with this process.
    I've tried sending a "kill -3 pid" but I can't seem to get a thread dump. I've eventually gotten some 700Meg core files. Is there anyway to use these core files to tell me what is going on?
    Any ideas on how to trouble shoot this problem? We've used some profilers but we can't duplicate the problem on test servers so we aren't learning anything new.
    Thanks,
    Brian

    Try pstack to read the stacks of the threads in the process.
    Try pldd to determine the shared libraries in the process then
    use truss to trace calls in any of these libraries to determine where
    the cycles are being spent.

  • Airport Process utilizing high CPU utilization

    I currently have a 13 inch MacBook Pro i7 (2012 version).  Recently I upgraded to Mavericks.  After using the computer for a day after the upgrade, I began to notice it becoming very hot and the fans running very high.  Looking at the running processes i noticed that a process called "airport" was running and utilizing high CPU times causing the heating up and fans running.  Once I stopped this process, the laptop went back to operating at normal levels.
    Unfortunately this issue began to come back several times....the "airport" process starting at any time and utilizing high CPU utilization....again only by killing this process fixed this issue.
    After seeing this behavior over several days, I decised to wipe the drive and install a clean copy of Mavericks in the computer.  Thought here was that possibly something did not carry over correctly from the upgrade from Mountain Lion to Mavericks.  Unfortunely this did not correct the issue with the "airport" process as it still is continiung to launch at any time and spike the processor until I manually kill the process.
    I do not recall this issue occuring while running Mountain Lion so it seems to be specific to Mavericks at this point.
    I was hoping to hear if any other have experienced this type of issues while running Mavericks.

    You should be able to find the information you are looking for from the default Total CPU Utilization Percentage monitor.  This monitor has a built in diagnostic task that will kick off when an alert is triggered to list the top cpu consuming processes.
     To find which processes were causing CPU to spike, simply review the State Change Events history in health explorer for the machine that was affected, for the Total CPU Utilization Percentage monitor.  I have modified my second screen shot
    to remove machine names, but you should get the idea.  If a cpu monitor went from green to red, it will run the diagnostic task and list the process information and cpu usage at the time of the alert under state change events.

  • Reader won't close down, running high CPU

    Hello, I've recently updated to the Reader XI thinking that it may solve my problem, but it was happening with the previous version also.  After viewing pdf files and closing the files, Reader still continues to run in the background.  CPU usage runs at 50% and if I've open multiple files, CPU usage runs up to 100%.  My computer is slow, lags, gets hot and the fan continues to run.  The only way I can seem to close the program is through the task manager.  The application shows as AcroRd32.exe*32.  When I stop the application, my system resumes to normal and the fan stops once the computer has cooled down.  Can anyone help with a solution?  I'm also running Windows 7.  Thank you kindly.

    I'm having the exact same problem as cmmcaw above -- and yes, I'm running Windows 7, too (and it's completely updated).  A few days ago, my computer slowed down to a crawl, the fan was running full blast, and the machine was getting hot.  The next time my computer was on, I scanned my system thoroughly, and there was no sign of malware.  The next time my computer's fan started churning, I opened up Task Manager and discovered that Adobe Reader X was not shutting down (and yes, my CPU was running at 100%).  I have now installed Adobe Reader XI in the hopes of fixing the problem.  It appears to work all right when I'm in my Administrator account, but when I'm in my User account, I encounter the same problem that I had with Adobe Reader X -- Adobe Reader just does not shut down properly.  Reader XI opens up just fine, and then it appears to close, but in reality Reader is actually running in the background, trying to fully close down.   
    In order to solve the problem, I tried to download the .zip file you suggested above, but it won't download (and that's on my Admin. account).  Adobe encounters some sort of error (it won't say what kind).  I tried downloading the file with my virus scanner turned off, but still no go.  Cleaned cookies, ensured they were enabled -- still no go.
    So, why does Adobe XI seem to work okay on my Administrator account, but refuse to shut down properly on my User account?  And how do I fix this problem?  I mean, I can alway just shut it down fully through Task Manager, but it's not supposed to work that way.

  • ITunes 10.5 has three processes that hog CPU 100%

    Since I updated iTunes to 10.5, there are three proceses that hog the CPU to 100% and everything comes to a screaching slow mode. These are APSDaemon.exe, MDCrashReportTool.exe, and AppleMobileDeviceSerivce.exe. Even when I close iTunes, these processes keep running and continue to hog the CPU.
    I am running Window XP on an IBM (Lenovo) Thinkpad T60 machine with 2GB Ram and T2500CPU @ 2.00GHz.
    What are these processing doing that takes so much CPU poawer. Before iTunes and iPad updates, they use to function properly.

    When I called Apple Support to ask about the 100%  CPU usage, they wanted to charge me because my Ipod was out of warranty.  I insisted on talking to someone and finally got to talk to a software engineer for free.  He said that he had never heard of the problem in his three years at Apple.  Nonetheless, he sounded really interested and suggested that it might be a conflict with anti-virus software.   I deleted the antiviruse and that DID NOT HELP AT ALL.
    It seems as if Apple could care less.    There is no official response.   Their primary response is to look at the Forum.   At least you find out that the problem isn't your fault, it really is Apple!!!!
    So far the best solution is just to delete iTunes and use Mediamonkey to sync your pod.
    Apple, please fix this!!!!!

  • Why is my laptop running high cpu after i render 3DS Max For a month and what should i do?

    I have been trying to run my long 3ds max finals. I have 2 fans blowing my Macbook Pro. The Laptop fan and a regular fan blowing my laptop. after a month of finish rendering. my cpu sky rockets and i i have try scan for malware, virus, spy ware and worms, which didn't do nothing, i also check for defragment. Nothing works. the 3ds max was running on bootcamp windows 7. When i render in 3ds max the cpu hits 100% non stop. should i go to apple store and to get it check and would it cost alot to get it fix? Thank you for anyone answering my question.

    The firmware controlling the fans is predictive depending upon what sort of software and it's CPU demands, you have been running.
    For instance, you say your 3D program maxes out the CPU, well the computer now knows whenever you launch this program it needs to crank the fans up, even if you don't use much CPU at first, in order to catch a sudden demand in CPU needs and not let the CPU burn up.
    Don't know if there is a remedy for this unless not to use the 3D rendering software, or use on a machine with more processing cores and better cooling, like a MacPro.

  • Pageserver.exe showing high CPU processing on server

    We have been running Crystal Enterprise 10 for awhile on the same server.  Starting Thursday evening the pageserver.exe process showing high CPU utilitzation on the server.  We have restarted all the Crystal services through the Central Configuration Manager but the problem still came back.  The high CPU utilitization occurs during the day and at night when no one would be running any reports.  Does any know what else we could look for?
    Also does a separate pageserver.exe start for each user that runs a Crystal report, we show about 6-8 pageserver.exe processes at any given time.  Is that normal?  When do these pageserver.exe processes go away.  I logged out of Infoview but a pageserver.exe process did not go away.
