Unable to set  kernel parameters using solaris 10

HI,
I'm trying to install DB2 8.2 on solaris 10.the problem i'm encountering in installation is unable to set MSGMAX and MSGMNB kernel parameters. I tried setting the new replacement parameter process.max-msq-qbytes through projects->Resource Control from the management console.but still uinable to set the parameters.
Can anyone help me in setting the above kernel parameters.
Its not possible to set it thru /etc/system.

    I finally had some time to find the actual syntax for tuning process.max-msq-qbytes and process.max-msg-messages. prctl will change those paramaters for an existing process.
    As a proof of concept I changed process.max-msg-messages to a 64k. process 2221 is my shell.
    prctl -n process.max-msg-messages  -r -v 64k 2221
    bash-3.00# prctl 2221
    process: 2221: -csh
    NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
    process.max-port-events
            privileged      65.5K       -   deny                                 -
            system          2.15G     max   deny                                 -

            system          4.00GB    max   deny                                 -And now to make this persist across reboots...
    So long as I'm experimenting, I'll use projadd and add a new project which just includes me and not the rest of the users in the group staff.
    bash-3.00# projadd -p 115 -U testuser \
    -K "process.max-msg-messages=(priv,64K,deny)" \
    -K "process.max-msg-qbytes=(priv,64K,deny)" \
    user.me This creates the following /etc/project:
    (note the last line is all on one line in the real file minus the \.)
    placer% cat /etc/project
    system:0::::
    user.root:1::::

    user.me:115::testme::\
    process.max-msg-messages=(priv,64000,deny);process.max-msg-qbytes=(priv,65536,deny)After a reboot I checked the values by loging in under my user and running prctl.

    ...Solaris 10 has different tunables and default values from 8 and 9. It's default tunables should be good for most applications per a given system's hardware. There are some great blog articles, and discussions on opensolaris.org and blogs.sun.com on tuning that explain the intent of tuning and why we shouldn't have to tune.

  • Y setting kernel parameters in linux and not in windows

    Hi Can any one please help me out...
    While installing oracle on linux we are setting some kernel parameters But when installing in windows are we setting any kernel parameters...We are not setting any parameters...can any one please explain why r we setting kernel parameters and what is the use of those parameters and why are we not setting any parameters in windows.

    probably because linux != windows
    anyway, there are still some recommendation you can follow, for example if you want to use more than 2Gb of memory in win32

  • Setting IPCS kernel parameters in Solaris 9

    I'm trying to install Oracle 9i on Solaris 9 but it fails during the database instance startup phase of the installation. The error message that I get relates to a failure in shmget. I read the Oracle docs and other docs and this is how I set the parameters in /etc/system:
    set semsys:semmni=100
    set semsys:semmns=1024
    set semsys:semmsl=256
    set shmsys:shmmax=4294967295
    set shmsys:shmmin=1
    set shmsys:shmmni=100
    set shmsys:shmseg=10
    I noticed that the semaphore and shared memory modules are not loaded when the system boots up, instead they are only loaded when the semget or shmget commands are called by dbca. When I execute the command sysdef I notice that these kernel parameters are set to the default values not the values that I specified in /etc/system. I am new to Solaris so could someone with an expertise in it point me in the right direction.
    Thanks in advance.

  • Unable to set bounding box using rectangle tool on small rectangles

    I just upgraded to InDesign CC and keep getting an error message "Unable to set bounding box" when I try to create a small rectangle. The tool works fine when creating a larger rectangle -- it only gives me the error when creating a very small rectangle. Never had this problem in CS5.
    Anyone else run across this?

    Check what your default stroke weight is. If the stroke weight is to wide for the size of the box you are trying to draw, you will get that message.

  • Unable to set up email, use BBM or App World

    Hi. I recently purchased the Blackberry Curve 3G 9300 v5 under Vodafone Australia but I haven't been able to set up email, use BBM or the App World. I've already installed the Desktop Software and BBM and App World from this website (the person at the shop apparently didn't do a thing). Here are the errors I received -
    1) I don't have the I would like to create new email account option, I only have the I want to use a work email account with Blackberry Enterprise Server option
    2) When I add someone's BBM pin, they don't receive notification for it and it's stated as pending on my side. When they try to add me, I don't receive anything to inform me to add them
    3) When I go to the App World button, I get the message Blackberry App World is having trouble connecting to the server, Verify your network connection then when I try to download it again at this site - I get the message 
    Sorry, your device does not meet the system requirements that are needed to support BlackBerry App World.
    Please help. I've gone to the shop where I bought this from but they were not very helpful. I need to know if they didn't set up my account properly so I can ask them to fix it. Thank you!

    Hi! I've contacted my provider and it turns out my account wasn't activated after a week! It's fixed now, thanks!

  • I had my Iphone5 stolen in France 2months ago, I now use my Iphone4. today my phone turned itself to the setup screen and i was unable to set it up using my itunes account because its been hacked in france im in uk.what do i do?.

    Ive had my iphone5 stolen when i was in France 2 months ago. i now use my iphone 4, but today my phone went to the set up screen when when you first get an iphone. i was not able to set it back up because some one had changed my password. i found this out when i went on to itunes on my computer and asked it to send email to me so i could change it and i recieved it in french. guess work i sussed it but im worried that they have logged into all my other accounts including bank. i rung the phone company 2 months ago to report stolen so i assumed my phone would have been blocked. ive lost everything on my iphone 4 including photos of my new born little girl which hurts.
    what can i do about this?
    how can i block my iphone5?
    is there any way of getting things back that i never backed up?
    this needs to be sorted so it does not happen to anyone else. i live in the UK.
    thank you all
          regards ricky..

    Sorry, without knowing the Apple ID/Password that was originally used to activate this phone, then there is no way to re-activate it, as you've found out.
    Apple can't/won't help you. Your choice is to get this info, or you simply won't be able to re-activate this phone.
    If you ex won't give it to you, then consult a lawyer.

  • Increasing kernel parameters Solaris

    Hi,
    actually i have these parameters and i need to increase them. Which will be the next values to be entered for those ones. Im using solaris 10 , oracle 10gR2.04.
    set shmsys:shminfo_shmmax=4294967295

    Thx

    Hi here i have answer for your query
    if you want to set kernel parameters on solaris means
    open the system file as vi /etc/system
    and type the following at the end of file
    set shmsys:shminfo_shmmax=4294967295
    set shmsys:shminfo_shmmni=2500
    set semsys:seminfo_semmsl=1000
    set shmsys:shminfo_shmmin=1
    set shmsys:shminfo_shmseg=10

  • Problem in setting the parameters for an OASingleSelectionBean

    Hi,
    I have created an advanced table, for which I have to allow single selection or mutliple selection according to my requirements ie dynamically. So, for single selection, I have created a OASingleSelectionBean dynamically and add this to my advanced table bean.
    I also want to set Action for the single selection option. I have set the action using
    setPrimaryClientAction() which takes an argument of oracle.cabo.ui.action.FirePartialAction class. Now I also want to pass certain parameters when the single selection event happens.
    For that, I have taken an object of FirePartialAction class and but using the FirePartialAction class .setParameters(oracle.cabo.ui.collection.Parameter[]) function. I am setting the parameters using
    Parameter class object.setKey
    Parameter class object.setValue
    But my problem is that I want the value for the parameters at runtime, for which I intend to use SPEL. But I am not able to use SPEL using the setValue method.
    So it goes like this in short:
    OAAdvancedTableBean.setTableSelection(OASingleSelectionBean)
    OASingleSelectionBean.setPrimaryClientAction(FirePartialAction)
    FirePartialAction.setParameters(Parameter[])
    Parameters.setKey(String)
    Parameters.setValue(String) --- In case of value I want to give SPEL as an argument as I get the value at rutime
    Is that any other way in which I can set the value for the parameters using SPEL?

    Hi,
    I got ur point.
    Although i have never tried.........Can you try using method
    Parameters.setValueBinding(new OADataBoundValueViewObject(<single selectionbean>,<vo attr>))
    In this way without the use of SPEL, you will be able to achieve the functionality!
    Try this and get back to me!

  • Using SET GET parameters in ITS

    Hi All,
    Is it possible to use set get parameters in ITS. We want to set some parameters in a BADI and read the value in ITS Template .
    Or is there any other method to do this?
    Thanks,
    Anubhav

    Sure. In your abap program use the following code
    *  ITS macros
    INCLUDE avwrtcxm.
    GET PARAMETER ID 'YOUR_PARAMETER' FIELD SAVE_PARAMETER.
    field-set u2018~YOUR_PARAMETERu2019 1 SAVE_PARAMETER.
    field-transport.
    in the template you can now use ~YOUR_PARAMETER.

  • Unable to open windows using boot camp.  Get message "The bless tool was unable to set the current boot disk."  Any thoughts, Thank you.

    Unable to open windows using boot camp.  Get message "The bless tool was unable to set the current boot disk."   I am using an Imac , Lion operating system, and Windows 7.  It worked a few days ago.  Any thoughts, Thank you.

    Note that nowhere in the Boot Camp instructions does it tell you to use Disk Utility to format the Windows partition. The Boot Camp Assistant program creates the partition & sets the +partition scheme info+ of the disk as appropriate for the Windows installer but the Windows installer itself is responsible for formatting the new partition with the appropriate +file system scheme+ (NTFS for Windows 7).
    If you follow the instructions in the Boot Camp Installation & Setup Guide to the letter you should have no problems installing Windows.

  • How to use SET & GET Parameters in Module Pool

    Hi Friends,
    Can anyone please tell how to use SET / GET parameters and PARAMETER ID for a text box (Input / Output field ) in module pool? What is the purpose and where do we need to do coding for it?
    Note : I will definitely give the marks for good responses.
    Thanks in advance,
    Pradeep

    Hi Pradeep,
    You can save values in the SAP memory using a parameter ID. These
    are user and terminal-session specific, but available to all internal and
    external sessions.
    SET Parameter copies the corresponding field contents into the SAP
    System memory in the PAI processing block.
    GET Parameter copies the corresponding field contents from the SAP
    memory at the end of the PBO processing block, after data has been
    transferred from the program, if the screen field still has its initial value
    You can link an input/output field to an area of the SAP memory in the
    ABAP Dictionary.
    When you use an input/output field that is defined in the ABAP
    Dictionary, its parameter ID is displayed in the Dictionary attribute
    Parameter ID in the Screen Painter.
    Usage
    SET PARAMETER ID: ’CAR’ FIELD space,
    ’CON’ FIELD space,
    ’DAY’ FIELD space.
    Here is the link that explains the usage of GET/SET in detail
