Too much childprocess on linux

Hello!
I use 9iAS 9.0.3 on Suse Linux.
Using the command "ps aux" and get a lot of childprocesses for each running jvm.
If i only start a standalone oc4j-container i have the same result.
My question: How can i set the max number of childprocesses running a jvm on linux?
Thank you!!!
regards
Harald.

I think you are seeing threads, not processes.
Dunno if you can configure their number though :)

    Harsh,
    1) What version of Oracle you running on 7.5 release of linux?
    2)How did you come to the conclusion that because of this, your update is slow?

    after that i started SAP on Quality server, it is taking too much time for opening SAP transactions (it is going in compilation mode).
    i started SGEN, but it is giving time_out errors. please help me on this issue.
    MY hardware details on quality server
    operating system : SuSE Linux 10 SP2

    Hi,
    >i started SGEN, but it is giving time_out errors. please help me on this issue.
    You are supposed to run SGEN as a batch job and so, it should be possible  to get time out errors.
    I've seen Full SGEN lasting from 3 hours on high end systems up to 8 full days on PC hardware...

  • NX 6125 too much time to complete POST. USB error

    I have been having some issues over the last week or two
    NX 6125 takes too much time to boot. I'm dual booting it , Windows XP and Linux Mint.
    It takes more time to complete the POST, during POST, LEDs on all the USB devices attached to it will go ON & OFF.
    then comes the boot menu. from that step onwards it works normally.
    Once it boots into Windows, there is a pop up "USB device malfunctioned" which keeps on coming even if no devices are attached to USB.(it has an internal card reader and fingerprint reader module)
    While using Linux, the kernel throws the error "  [ 2094.490070] hub 1-0:1.0: connect-debounce failed, port 2 disabled "
    Checked the RAM with memtest and hdd with self test from BIOS, says OK.
    The major issue is it can't boot from any other devices other than internal harddisk !
    Previously I could boot Linux frm DVDs and bootable USB drives.
    Windows XP cd when booted gives "NTLDR missing" error.
    Kindly help me.

    card reader is a usb device, not sure about the fingerprint reader.
    one of them has malfunctioned. check the card reader slot for debris.
    You may have to open up the  notebook and disconnect the card reader, see if the error stops.

  • OIM 11g using too much memory and not releasing it when shutting down

    Hello,
    we have a problem with OIM 11g using too much memory (about 5gb) and it's not releasing it at shutdown (4gb still used).
    We are using a VM with RedHat Linux 5.6. Originally we had 4gb RAM + 2gb swap file. We installed Admin Server, OAM, OIM and SOA on that machine but quickly realised we couldn't run all 4 programs at once in 6gb. AdminServer could run with 2 other products, but it was a tight fit in memory.
    So we increased the RAM to 8gb (still 2gb swap file). But then our problem occured : I start the Admin Server (2.7gb total memory used), then OAM (4.6gb total memory used) and then OIM. After it started the server is now using 9.6gb of memory (~300mb of free memory) ! The problem gets even better : after I shut down everything (OIM, OAM, admin server) the "top" command show that there is still 4gb of memory used even tho nothing else is running on the server ! There is absolutely no other process (other than root stuff) running and no other users connected to the machine. After a reboot, it shows 400mb of memory used. I tried restarting the programs and it did the same thing.
    Our intuition is that there might be a memory leak or some bug in OIM that might use up almost all the free memory and it's not releasing it upon shutdown. It might have been there before we increased the memory but have not noticed it since memory was already tight.
    Anyone encountered the same problem ? Any idea ? Any suggestion to narrow down the problem ?
    Thank you

    You can adjust the memory settings for WLS by editing the setSOADomainEnv.sh file that can be found in your /middleware/user_projects/domains/<domain>/bin/ folder. There is an argument called PORT_MEM_ARGS which is used to set your Java memory arguments. This way you can decrease/increase the amount of memory used by each managed server.
    I usually type "ps -ef | grep oracle" to see what processes are running by the oracle user. This way the output doesn't get cluttered with root processes.

  • Firefox uses too much memory

    I've been using Firefox as the default browser on my systems (both Windows and Linux and in 32 or 64 editions) and for some reason Firefox consumes too much memory. Now trust me. I have a very fast machine and so I get very frustrated with this issue as it seems to be a Firefox only issue. Its true that I might have up to 40 tabs open at times but Chrome can handle it Safari can handle it and even Explorer can handle it. Sometimes Firefox's memory consumption peaks to an astonish 3GB of memory which is unheard of. My machine is so fast that I can have up to 10 programs open (Maya, Photoshop, Cinema 4d, Autodesk Suites MySql server and PHP5, MS Office) and still be able to work with them all at the same time, but Firefox crashes suddenly and that is very annoying as I've customized it to my needs adding extensions and making sure all my online baking is done using Firefox. This memory issue is far more noticeable when I'm using Windows 7 64 bits. The same amount of tabs and extensions opened on Linux have no effect on memory and I often switch to Linux just to be able to enjoy a smooth Firefox browsing experience. I've invested so much money into building an amazing machine and it takes 10 minutes of having Firefox running to crash it all completely. I've lost track of the amount of times I've lost my profile and had to rebuild all my customizations but I can stand that. What is beyond my comprehension is the fact that when I'm using Windows XP or Linux the memory used by Firefox is far lower than when I'm using Windows 7 or 8.1 .
    Can you help me out? I really love Firefox and would like to keep using it as my default browser but can't afford losing my profile info every time Firefox crashes or having Windows Explorer crashing and losing all the work I'm doing on other software programs.
    Much appreciated;
    Sam

    Are there any tabs reopened from the previous session when this happens?
    Do you keep a large history?
    You can check for problems with the places.sqlite database file in the Firefox Profile Folder.
    *http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox
    *https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file
    You can try to check and repair the places database with this extension:
    *https://addons.mozilla.org/firefox/addon/places-maintenance/
    Try to create a new profile as a test to check if your current profile is causing the problems.
    See "Creating a profile":
    *https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
    *http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
    There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
    If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
    See:

  • Initramfs too slow and ISR taking too much time !

    On my SMP (2 core with 10siblings each) platform i have a PCIe deivce which is a video card which does DMA transfers to the application buffers.
    This works fine with suse13.1 installed on a SSD drive.
    When i took the whole image and created it as a initramfs and running from it (w/o any hdd) the whole system is very slow and i am seeing PCIe ISRs taking too much time and hecne the driver is failing !
    any help on this is much appreciated.
    there is a first initramfs iage which is the usual initrd the opensuse installs and i patched it to unpack the second initramfs (full rootfs of 1.8GB) in to RAM (32GB) as tmpfs and exec_init from it.

  • How do I fix Javascript message that says "too much recursion"?

    Hi there, every time that I load up or refresh a webpage in Firefox, I'm getting a message popup from Javascript that says "too much recursion" - I have no idea what this means or how to fix it, but it's gotten to a point where it's making it almost impossible to do anything through Firefox as it's popping up so often. Is there a way to make this stop?

    Hello lavendermoon, maybe an installed Extension that have problems with their JavaScript is the issue, to check that '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
    If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
    *In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
    *In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
    If Firefox is not running, you can start Firefox in Safe Mode as follows:
    * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac: Hold the '''option''' key while starting Firefox.
    * On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    When the Firefox Safe Mode window appears, select "Start in Safe Mode".
    :[[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
    ''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    also try to delete in your [http://kb.mozillazine.org/Profile_folder_-_Firefox#Windows profile folder] the [http://kb.mozillazine.org/User.js_file User.js file] you have.
    The user.js file does not exist by default. If you create the file, forget it, if you have not create the file then delete the User.js file, to see if the problem goes away (some programs create and write in the file also).
    thank you

  • What does iTunes FORCE YOU to download the last version of their software to use their store? The new program is too much for my computer!

    This totally *****...iTunes 10 is too much of a memory hog for my POS computer. I have to turn off all other apps just to use it and even then it still runs SLOW. I think iTunes = Extorition. Why force us to use it? They just want to track your personal data. That's pretty evil. The best iTunes version for my computer was iTunes 7. But it won't let me use store on iTunes 7. F@#$*%s!
    Instead of making the program more streamlined, they make the next version LARGER FILE SIZE and more of a memory hog. 
    Apple should be making each successive version a SMALL FILE SIZE and less of a drain on memory.

    Windows doesn't defrag on the fly, you have to run anti-virus all the time. The PC vendor installs all their "crapware" on the machine too.
    Also most PC's don't come with hardly any RAM neither, most people don't know computer specs, don't know how to look up their prospetive machine on the internet and see if they are getting their money's worth.
    Microsoft is a enemy too, they allow "toolbars" Acive X and purposely bloat their operating system so it forces you to buy a new one.
    At least with iTunes you have a choice to buy your music ANYWHERE, you could have kept on using iTunes 7, just you would have had to buy your music via cd's or another website like Amazon etc.
    Microsoft has really bloated down the last few updates of Windows, I replaced all the old Dells with 512MB of RAM and 16 year old single core Cellerons with copies of Linux Like XP so the seniors at a local center can still get on the internet if they need too.
    Still even with that the last few updates of Linux have been a bit rough for those old machines, but for the net that's good enough.
    LOL!

  • WRT54GX4, Too Much Power (?)

    I recently turned the "Roaming Aggressiveness" in the wireless card settings on my laptop (M1710/Intel 3945ABG) to the LOWEST setting, and it stopped the constant signal dropping.
    I've also discovered the closer I get to this router the more the signal level fluctuates--and the more frequent the dropouts become. Removing two of the antennas actually HELPED stabilize the reported speed when I was in the same room with it.
    With analog devices I've heard in the past of "bad" reception from getting too close to the source and overwhelming the receiver. Now I'm wondering if the problem with this router for some users is too much power? How would you measure the power output as opposed to "signal quality" and speed reported by the software?
    Also kind of wondering, is it possible too many other Linksys routers in my neighborhood would be causing problems? Maybe this is why going with alternate brands fixes issues? I see an awful lot of "Linksys" SSIDs, sometimes with more bars than mine..

    If that's the case, I strongly suggest changing the ssid and channel to 11 or 1 and securing your wireless network.
    The box said windows xp or better... So I installed Linux!

  • Malicious or not? Message popped up: Mozilla security found (something like too much, forget exact word) activity on your computer so it will do a fast scan of system file. With OK button.

    I was looking at youtube.com, which always tells me my browser is not supported and recommends I download Firefox, but that is what I was using, so I went to Firefox to check for updates. (I think I also had freecycle.org open.) Then this message popped up in a new page: Mozilla security found (something like "too much", forget exact word) activity on your computer so it will do a fast scan of system file. There was an OK button. The page address was: http://update17.stegner.ce.ms/index.php?Q7Lhl9ShbRxGJXpkM1VLSi4ZE8H4pTedoVPySgeppM3VpC+thEspcFG7qxHgn1pdsC2h5ygPGWI3t5hXqMzL9EQaZZ3J1e3CKXgCb0Qp. I did not click OK but copied the link and closed the window which closed the internet. I have never seen this before and would like to know if it is really Mozilla or possibly something malicious. Thank you.

    Good catch. That almost certainly is an invitation to download malware.
    There are a lot of infected web sites pushing "fake antivirus" software. If you have any doubts about whether your system might have become infected, you can supplement your regular security software with these two highly regarded scanners:

    Connected a non-apple CD drive to my macbook and after that started receiving this message: "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
    initially I was receiving this message after I switch on my macbook but now after every 30 seconds this message pops up although I never connected anything to my macbook through its USB ports.
    Will highly appreciate for your help on how to get rid of this problem.
    Regards
    Homayun

    Try resetting the SMC
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

  • Can too much memory lead to a kernel panic on a MacBook Pro? specs 2.4GHz intel core i7 16GB DDR3 RAM   late2011..My laptop began suffering from kernel panics 3 mos ago first noticed using public wifi. Gone thru apple support all the way to engineers

    Can too much RAM memory in a late 2011 model macbook pro lead to kernel panic? That is what I was told by a senior supervisor from apple support who troubleshot this issue.First noticed this problem in Dec 2014 while using a private wifi at a relative's home. Did not occur again until Feb1 using a public wifi at a hotel. Never happened on my private wifi network until last night  attempting to use airplay. ( have used airplay before without issue). Late 2011 MacBook Pro running 10.9.5; 2.4 GHz Intel core i7, 16 GB DDR3,AMD Radeon HD 6770m 1024 MB graphic card.  The laptop came with 8GB RAM and I installed 8 GB about 2 years ago for some reason I cannot remember... probably because I thought the system was slowing down a little. I know that sounds silly. I do not run multiple programs at a time except I leave 6-8 website tabs open simultaneously. I don't photo or video edit.  I would describe my use as "light"  based on reading these blogs.I had purchased apple support and spent hours on the phone with them in early Feb moving up through support  and senior support to sending logs to the "engineers." Of course lots of things were done some of which I am sorry to report I cannot recall their technical definitions. Deleted  3rd party apps/programs; re-worked start up menu; re-installed operating system; reset " this, that and the other" using acrobatic simultaneous key strokes both in and out of safe mode..Anyway the results from the engineers came back and they suggested that if it happened again I was to remove the 8GB of RAM I had installed as the system was getting confused as to which chip to use.( that is my interpretation of what was said..prob dumbed down for me)...Anyway 1 day after these pronouncements came down I read that Apple had agreed to fix  graphics cards in some late model 2011 MBPs. I felt this was unlikely to be the issue  given all that had been done including an extended hardware test but called the Senior Support Supervisor I was working with to ask him to make sure. He never phoned me back. Should I go to the trouble of removing 8GB of RAM from my laptop? Of course I will try it as the alternative is a new computer.Blogs read that this model can support 16GB but Apple didn't test for it. Senior Supervisor claims this is my trouble.  Does that make sense?  Not to me....but it is clear to all my level of knowledge.  Can a malfunctioning graphics card be missed by an extended hardware test? I appreciate comments.

    The RAM needs specs as shown below.
    Maximum Memory
    16 GB (Actual) 8 GB (Apple)
    Memory Slots
    2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
