Security parameters in the kernel do not meet the minimum requirements

Hello,
I am installing Oracle AS Infrastructure.
My overall system checkup was fine but of kernel has following message.
checking for hardnofiles = 65536 found hardnofiles = 1024 Failed
checking for softnofiles = 4096; softnofiles = 1024
Problem:
The security parameters in the kernel do not meet the minimum requirements.
Recommendation: Perform OS System specific instruction to update kernel parameter, namely BIT_SIZE and NON_EXEC_USER_STACK.
After that I have checked /etc/security/limits.conf file values were correct.
But my /proc/sys/net/ipv4/ip_local_port_range
values were 1024 65000 --
they are correct in sysctl.conf file
But any way I have fixed that.
Also /pro/sys/kernel/shmni was 1000, so I make it 4096
Actually in the start of setting up requirements,
I have tried to make changes of kernel through /proc/sys/.....
But after that I have created sysctl.conf file and put all recommended values and restart the system.
So I continue installation.
Is it ok?

DN

I have changed to
/etc/security/limits.conf:
* hard nofile 65536 --- I removed this line also
* soft nproc 2047
* hard nproc 16384
* soft nofile 16384
* hard nofile 65536
after that I got the values as below
ulimit -Hn
1024ulimit -Sn
1024I run ulimit -u 1384 -n 65536
ulimit -Hn
65536ulimit -Sn
65536I put the values back and reboot system.
* hard nofile 65536
* soft nproc 2047
* hard nproc 16384
* soft nofile 2048
* hard nofile 65536
Right away from the terminal, its give me values again
ulimit -Hn
1024ulimit -Sn
1024But after some time remotely (SSH) I have checked
abc:~ # ulimit -Hn
65536
abc:~ # ulimit -Sn
2048

  • I'm trying to download the trial version of Adobe Illustrator. An error message says that the OS does not meet the minimum system requirements for the installer. 10.6.0 is the minimum required for installation. How do I get my mac to be a 10.6.0 ?

    I'm trying to download the trial version of Adobe Illustrator. An error message says that the OS does not meet the minimum system requirements for the installer. 10.6.0 is the minimum required for installation. How do I get my mac to be a 10.6.0 ? Right now I have a 10.5.8 is there a way to upgrade or something?

    Buy the Snow Leopard retail installer (http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA).
    That will take you to 10.6.3.
    If required you can then use the combo updater to get to the latest version, 10.6.8 (http://support.apple.com/kb/DL1399)

  • HT6030 I downloaded Mail Update for Mac OS X 10.5.6 and was told it could not be installed because it was from an unidentified developer.  Tried installing download from MailUpdate & advised the disk did not meet the requirements for update. Hmmmm.

    I downloaded Mail Update for Mac OS X 10.5.6 and was told it could not be installed because it was from an unidentified developer.  Tried installing download from MailUpdate & advised the disk did not meet the requirements for update.   Expect it's due to being at 10.9.1.  Mail is still teetering between dysfunctional and non-functional.  Advice?

    I'm not sure what "Mail Update for Mac OS X 10.5.6" is. Mac OS X 10.5.6 is Leopard, a system that is quite old at this point. There have not been any Mail updates for Leopard in quite some time. If you are trying to install some old Mail update for Mac OS X 10.5.6 in Mavericks, that won't work.
    If you are trying to install the Mavericks Mail update manually, that's not necessary if you have updated through the App Store. If the App Store shows no updates, you don't need this. (The error message doesn't make sense, and may indicate some other problem with your system, assuming that you were downloading this update from Apple's site.)
    I'd advise you to start a new topic in the Mavericks forum and describe the problems you are having with Mail. Be sure to include specifics, but try to avoid speculating on causes, as responses that may be related to an inaccurate assumption on your part can cloud the issue.

  • UserPrincipal.ChangePassword thinks the password does not meet the password policy requirements.

    I am working with C# 3.5.  My goal is to have a simple program to allow a user change their Active Directory user password via a web page.  I have a console application to initially test the commands to active directory and I am running into a problem.
    my domains password policy is as follows.
    Enforce password history 24 passwords remembered
    Minimum password length 7 characters
    Password must meet complexity requirements Enabled
    Store passwords using reversible encryption Disabled
    The error I am getting is "The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements. (Exception from HRESULT: 0x800708C5)"
    I believe the new password I am using does meet the policy requirements and I can't seem to get this program to work.  All I want to build is a simple program to allow a user to change their Active Directory user password.
    My test code is below.
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.DirectoryServices.AccountManagement;
    using System.DirectoryServices;
    namespace ActiveDirectoryHacking
    class Program
    static void Main(string[] args)
    PrincipalContext adPrincipalContext = new PrincipalContext(ContextType.Domain, "192.168.1.26", "OU=Staff,DC=SFdev,DC=org", "John.Doe", "Initial Complex P234dfword");
    Console.WriteLine("Validate user {0}", adPrincipalContext.ValidateCredentials("John.Doe", "Initial Complex P234dfword"));
    UserPrincipal user = UserPrincipal.FindByIdentity(adPrincipalContext, "John.Doe");
    Console.WriteLine(user.DistinguishedName);
    user.ChangePassword("Initial Complex P234dfword", "e$213434sDKS really? www.microsoft.com");
    //user.SetPassword("Initial Complex P234dfword");
    user.Save();
    Console.WriteLine("Press a key to exit.");
    Console.ReadKey();
    The .SetPassword works if I use a user with Domain Admin access but it appears the John.Doe is unable to change their own password with the .ChangePassword method.
    The output until the exception is the following
    Validate user True
    CN=John Doe,OU=Staff,DC=SFdev,DC=org
    I have no clue why any password I select for the new password does not work.

    I looked into the password policy and this is what I have learned.  There is a major difference between undefined and defined in policies plus making sure the defined policies are set with values that will provide the desired results.
    Since this is a development domain and is used for testing I have tweaked the password policy to allow me to develop and test against the domain with a little bit more freedom than a production domain.
    I have changed the policy to the following settings. 
    Enforce password history 0 passwords remembered
    Maximum password age 0 days
    Minimum password age 0 days
    Minimum password length 7 characters
    Password must meet complexity requirements Disabled
    Store passwords using reversible encryption Disabled
    Now, I am able to run my program against the domain testing the password change utility.  My error was leaving some of the policy settings as not defined and not understanding what that really means for each setting.  For development of a password change utility I need the flexibility to test and the relaxed policy changes allows me to run the program many times without having to work with test data that works around a more restricted policy.

  • Best way to announce that the hardware does not meet the minimum requirements

         Hi Everybody!!!
         I'm in the process of tiding my App up, and I stumbled into a requirement that needs to be addressed. I'm not quite familiar with the latest trends, so I was wondering if anybody could recommend a way to inform the user if the hardware
    to use does not meet the minumum requirements.
         In a nutshell:
     * I just created a game using Direct3D / DirectX 11,
     * I'm using "DrawIndexedInstanced", which means that the videocard to use should meet at least DirectX v10 (my shaders are using model 9_3 but I tested it in a computer with DirectX9 model 3 (or so the nvidia brochure said), and the game pretty
    much died in my arms).
     * According to the App Certification Requirements: "if you choose a minimum feature level higher than 9_1, your app must detect at launch whether or not the current hardware meets the minimum requirements. If not, the app must display a message to
    the customer detailing the Direct3D requirements."
     * I know how to detect the Direct3D level supported by the current videocard. What I would like to know is how to tell the user that the videocard does not support the minimum requirements.
         I don't have much knowledge about the current trends:
     * I assume that displaying a message box may not be the best option, as that would mean I need to link the MFC layer to do so (the game is in Visual C++ and that's what I would do if it were one of my day-job projects). I'm quite sure that
    is too much of a library just to show a message box... not to mention that most likelly the MFC is no longer supported in a Metro application...
     * I was thinking about displaying a nice graphic warning about the issue, but if the D3DDevice1 is not what I expect then I don't think I can be sure that at least it can display the graphic with the information.
     * I'm not quite sure if I should be linking to a .NET Library ("System.Windows.Forms" comes to mind), but then again maybe it's too much of a library for just a messagebox.
     * Then again, displaying that message in a command prompt may not be the best idea either.
         Any help is greatly appreciated!!!

         Hi Chuck,
         I tried your idea, but the game always crashed when calling the DrawIndexedInstanced() function in a computer that only supported DirectX Level 9.1 (plenty of those computers at my day-job, sometimes I swear this office could be
    a museum). The crash started as a driver unload call, and after that everything goes down.
         I also tried using the WARP mode, but the performance was horrible, and after a minute of playing I started to have temperature issues with the CPU (I did not see that one coming)
         What I finished doing was to create two sets of shaders (pixel and vertex):
     * If the feature reported by D3D11CreateDevice was 9_3 or above, I'd use my very own and happy shaders, compiled in 9_3 model. Beautiful performance with DrawIndexedInstanced().
     * If on the other hand the feature reported by D3D11CreateDevice was either 9_2 or 9_1, I'd use a set of shaders compiled for level 9_1. That seemed to be enough to draw a couple of images on the screen and tell the user, using my own game elements,
    that the computer did not match the hardware requirements.
          It looks like this was a good approach. My game passed the certification test, and it is currently on the AppStore.
          Best Regards,
          Tarh Ik

  • Hard drive "does not meet the requirements" for system updates

    Hi,
    I'm running 10.2 and I'm trying to update my computer to the more recent version, except that I've gone through the update downloads on this site and anything higher than 10.3 tell me I need to run 10.3 to run it. When I tried to upgrade to 10.3, I was told that I "cannot install this software on this disk. This volume does not meet the requirements for this update". What does that mean and how do I rectify the problem? Thank you very much in advance.
    - Jen

    Hi Kappy! I have a similar problem: I had a problem in the past and had to re-install the system. I now have a previous sytem folder on my mac which I do not dare touch. I used to have a later version than 10.3.3 (I cannot remember which). I am now trying to update with the 10.3.9 combo update (just bought a new ipod) and I get the famous "does not meet the requirements" message. I have repaired permissions and done Onyx maintenance - still nothing. I wonder whether somehow the installer detects that there is already some newer component installed and does not want to re-install. I am awfully frustrated... Thanks in advance for your help.

    is there a way to install this update?

    Hello
    More information would be useful, for example which Mac OS are you running.
    On the left menu item  About this Mac provides useful information.
    Also did you use Software Update to determine the update?
    Using Software Update can ensure you download and install the correct package for your particular Mac and OS version.

  • I would like to run the most secure version of firefox on my computer, but my computer does not meet the system requirements for the latest version

    i would like to run the most secure version of firefox on my computer, but my computer does not meet the system requirements for the latest version. is there a way i can have the security of firefox 8 and still be able to run it on my old computer. i currently an running firefox 3.6. it is a bit slow, but it is functional.

    Currently Firefox 3.6.24 is as secure as Firefox 8.0.1 is. Firefox 3.6.x will continue to get security updates until next spring, although the exact date hasn't yet been determined.
    Which of the system requirements are you lacking? <br />
    Processor wise you're stuck with what you got, but RAM can be upgraded. WinXP is still supported in all versions of Firefox and will be continued to be supported until Windows drops support for WinXP sometime in 2014.

  • Im trying to install a new application on my mac but it keeps on coming up with 'The volume of this disk does not meet the requirements for this update' any ideas how to solve this?

    I have recently fully updated my mac to 10.8.2 and i am trying to install a small facebook application but every time i come to chose the disk it says ' OS X facebook developer preview can not be installed on this disk. This volume of this disk does not meet the requirements for this update' any ideas on how to get round this?
    thanks

    That may be the new Mountain Lion "sandbox" protective software kicking in, possibly, because ML "thinks" that App doesn't meet ML's new strict security requirements.   A common phenomena.  If you feel the 3rd party App is really OK, you can override this feature and install the new App by holding down the Command key when you click to install the new App.  That's one possibility for the error message appearing.  If not, another possibility is that that Developer Preview software package requires some previous piece of software be installed prior to downloading this Preview.  You would have to check the Facebbok websiste's Developer Forums for help if this is the case.
    Hope this helps

  • Error "Sorry your device does not meet the system requirements that are needed to support Twitter for BlackBerry Smartphones"

    I have a Curve 8300.  With OS v4.5.0.81.  And I am on a BB Social network plan through my cell providor "Fido".
    I mainly use it for Facebook & Twitter  and have no problems using either app.  However I was prompted for an update for my twitter recently but wasn't near a wifi spot to update.  Just decided to update today at home where I do have wifi.  However when I go to do the update, it gives me the following error:
    "Sorry your device does not meet the system requirements that are needed to support Twitter for BlackBerry Smartphones"
    I have scoured for answers but haven't had much luck.  I tried checking for OS updates.  I apparently have the most current one that my phone will support.  I uninstalled twitter and then tried to reinstall it via the twitter Icon on my phone.  Got the same error.  Tried reinstalling it through app world, it installed just fine.  However it installed the version that I had previously had.  So I went to twitter's settings and checked for updates.  It prompted for one as I expected it would.  And when I tried to get the update.  It gave me that error again.  I can use twitter as it is, but I don't see why my phone shouldn't be able to get all the updates for various apps.  Is it a software compatability issue?  Is it a hardware compatability issue?  Is there anything I can do to get the update or do I just have a phone that won't take some app updates?

    Hi and welcome to the forums!
    The 8300 is not listed in the device upgrade table for Blackberry device OS v5.0. The newer versions of apps like Twitter and Facebook require device OS v5.0 to run correctly. Might be time to consider a new device!

  • Unable to create rule Error:Function Module does not meet the workflow conv

    Hi Workflow experts,
    Could any one help me with rule creation. Below is my Function Module Interface.
    ""Local Interface:
    *"  TABLES
    *"      AC_CONTAINER STRUCTURE  SWCONT OPTIONAL
    *"      ACTOR_TAB STRUCTURE  SWHACTOR OPTIONAL

    The function module test is successful with all required conventions for workflow but while i try to create a rule with the funtion module i get the error "Function Module does not meet the workflow conventions"
    I Also have included the following in FM

    Any suggestions would be helpful. Thanks in Advance,

    Hi,
    I am not sure whether the rule accepts the optional flag. Remove the optional flag for the tables parameters and try again. According to the documentation you have implemented the right interface. It might be the issue with the tables parameter being optional.
    Hope this helps,
