Installation on RHEL 5.4 11.2.0.1.0 (64-bit) > how to determine the shmmax

Hi, everyone-

I try to install on RHEL 5.4 11.2.0.1.0 (64-bit). I have a total of 46G of memory.

It is said that in the Oracle documentation:
"The minimum required value for shmmax is 0.5 GB. However, Oracle recommends to set the value of shmmax 2.0 GB for optimal performance of the system. ».

In the other docs it says it should be 50% of the total memory.

Please advise!

If you have access to the Support of Oracle, see notes

    installation of El Capitan in a mac by usb, but only using windows to create the USB

    I'm having a problem to install el capitan on a mac book pro 2009 has changed (dead) to an ssd HARD drive

    I can't find that any information how to do this from a windows machine (now only available) of the old system had the lion as I was told and when trying to install lion line or wireless it says it isn't available now so the machine is stuck without an operating system.

    If you are anywhere near an Apple Store, I would suggest bringing your MBP to and asking to help. For USB, you need to partition and format to allow to boot on a Mac, what Windows can not do. Then either create a bootable installer or install OS X on USB and then copy the installer it, boot from it and run the installer with the SSD as a target.

  • Satellite Pro A300 - how to access the installation of Vista hidden partition?

    AHOY!

    I have a Satellite Pro A300 PSAGDA 2000R

    It had Windows Vista installed when I got it, but after a while, had to reformat, so I did, (I want to reformat my computer every 6-12 months on average), it came only with XP disks even if he got a serial number for Vista on the underside of the laptop so I installed XP. That was about 2-3 reformats there now.

    However, so that finding drivers I've seen mention of a hidden partition to reinstall Vista (which I hope it is 64-bit) and tried to do this several times but unfortunately it does not work, I guess that maybe what XP installation I can accidentally deleted or something? (Thought they had in fact on some solid state memory which could not be written more or something.)

    * Is there a way I can access it, take another that won't cost a ridiculous amount (for example download) or a nice person enough to create an image to download on a site or something that I can download file sharing? *

    I have also a spare copy of Vista (and a bit of XP) on the drive, none of them will work?

    + Another thing which I am interested in is can I get any of the preview of Windows 8 OS that will run on this laptop? Apparently it improved performance on Vista and W7 would be convenient for running on a laptop, and I have also heard say it is possible to upgrade to the full version of the preview or W7 for a minimal cost and would probably be much cheaper than other methods if possible. +

    And I'm actually quite handy with computers, so don't be afraid to throw big words at me,

    (Tried the methods found on the manual on page 3-8 ([link: http://www.mytoshiba.com.au/support/computers/satellite/pro/a300/psagda-02000r/download?os=22]).)

    I have European A300 and I believe that the principle on the rest of the same models.
    A300 was offered with Vista preinstalled but without recovery disc Vista. Image that contains the operating system, drivers, tools and utilities for recovery has been saved on the HARD drive and with book factory owner was able to begin the installation of HARD drive recovery. It works with the factory only settings.

    With preinstalled Toshiba laptop recovery disk creator owners have been able to create the recovery disk that can be used if the disk HARD recovery doesn't work anymore.
    If you don t have access to this image saved on HARD drive recovery, you must use the recovery disc. If you don t have the disc that you have a problem. Recovery image can not be downloaded. All you can download are the unique rivers, tools and utilities that you can use if you install a clean version of the OS (operating system).
    On the European models, recovery image was recorded on the second partition of HARD drive in the folder called HDDrecovery.

    Anyway, A300 works with Win7 32 bit. I installed it on my machine and I m very happy with it.
    > Another thing which I am interested in is can I get any of the preview of Windows 8 OS that will run on this laptop?
    I put t know who should give you this overview, but the fact is that you get it from Toshiba. You should check if you can get it in another way.

    Since the installation of El Capitan, my streaming to my Audioengine DAC D2 cut after 12 minutes (the default duration of sleep). It will restart by pressing the space bar. When I change the duration of sleep, the cut outs are becoming more frequent and intermittent. Help?

    I checked the wifi and changed frequency (new modem, frequency change made no difference). The Board battery seems fine - all updates well. My computer is an iMac (2011), 3.1 GHz Intel Core i5, 8 GB 1333 MHz DDR3, with a new AMD Radeon graphics card. I recently installed a State strong 1 TB SATA drive and fitted with a LaCie Porsche 4 to USB for backup and a 4TB disk storage RAID LaCie drive.

    I'm frustrated, having to come in my computer since my living room every 12 minutes to continue to listen to Spotify on my stereo system.

    My guess is there a bug in the software of sleep in El Capitan, which disrupts his (I've tried different USB ports connect the Audioengine sender and same thing).

    Should I go back to Yosemite?

  • How to edit the Windows Installer build system Path Environment Variable?

    My library feature vi uses appeal to post a link to a dll, the dll calls several other dll.  If I create an installation package and install and put all the conscripts of the dll in the Windows\System32 directory on a target program machine works very well.  I prefer to keep all the DLLs of the program in a subdirectory of the executable file.  How to change the variable path of registry during installation so that windows will use this path? OS is XP and Windows7.

    Hello

    and why don't you copy your dll (and other levels) in the Wondiws\System32 directory on the installation?
    There are options in the installer to do such a thing.

  • How to get the support of the place of installation files in the specific folder

    Hi, I am using the LabVIEW2009 Setup program for the first time. I have not used any precedents, then my understanding is limited. I created a project and an executable and wants to direct the installer to put a few groups of files in a number of directories in which the executable file will. On the source files page, I see a number of descriptions of record in brackets. I don't understand how to use them. They are set up to point to specific directories? If so, how? So far, I managed to create an installer that puts all the support of the project files in a single directory. My attempts to select a subset of files in the project view window and place them in a separate Directory could not because they are treated as an indivisible group. Basically, I don't know enough about Setup and my research for more information only provided very basic information. If anyone can help by providing or pointing to more detailed information, I would be very grateful. Thanks George

    David,

    Thank you once again. The problem is solved! I had read the help and tried to put \Binaries in C:. It is useful if you run the installation program not only the creator of the installer! It was a situation "can't see the forest for the trees" at the last stage. It was a long day!

    Best regards

    OK - it worked.

    However, for 64-bit installations, I had to use the WOW of SQL Express 2008 versions, because, the Citadel is a 32-bit database and installation of 64-bit native versions would not allow an upgrade of the Citadel of Instance.

    You understand that you will not be able to upgrade Windows XP to Windows 7?  He will have to do a clean install.

  • 32-bit installation of Windows 7 on HP Elite 8200 Ultra Slim 64-bit

    Hi, I have big Windows 7 32 bit installation issues on our HP Elite 8200 Ultra Slim A2K41ET of 64-bit PC.

    The mediums of recovery are all for 64-bit

    We are a school using RM CC4 that installs Windows 7 32 bits for all client systems. Our server system does not accept the 32-bit driver for HP, so I was unable to deploy Windows 7 on our new HP Elite 8200.

    I really need the 32-bit driver, including the .ini to add to our file generation software, but I couldn't find it on the HP website. It provides only exe installers which come with many files of different driver for different operating systems and CPU architecutres.

    Otherwise, I was going to install a copy of vanilla Windows 7 32 bit to the HP system, but when the Windows Installer starts, he says that it is impossible to find the necessary drivers, but it does not say what he needs!

    Any help and suggestions would be greatly aprecaited.

    Hello:

    No driver is required to install Windows Vista or Windows 7 on a HP Elite 8200 desktop computer business.

    You use a real MS W7 x 86 installation disc, or the one you burned the ISO file download yourself?

    If you get the DVD, then you have one of two problems...

    1. you do not have the complete file download, even if it says "Download complete" (check the size of the file on your DVD against the size of the Digital River file when you start the download).

    2. you do not burn the ISO at the slowest possible speed that you have leading to the PC with the DVD playback problems.

    If you continue to have problems installing via DVD, use the installation of USB flash (you need a 4 GB flash drive) by following the instructions below:

    Download the MS of W7 USB installation tool and read the instructions on the page to use.

    http://www.microsoftstore.com/store/msstore/HTML/p bPage.Help_Win7_usbdvd_dwnTool

    You may also make this mod as I did if the flash tool-error.

    Download the bootsect file form http://www.everettsporting.com/bootsect.zip

    You will need to go into Control Panel, select display large icons, go to the icon of folder options, view tab, and select the hidden files and folders option.

    Once downloaded, copy the BootSect.exe file in the same folder that contains the file of Windows7-USB-DVD-Download - Tool.exe installed. This file in Windows 7's default installation directory is C:\Users\USERNAME\AppData\Local\Apps\Windows 7 USB DVD Download Tool\

    Run the application from the Windows 7 USB/DVD download tool as described on the Microsoft Store website. The end result will give you a boot USB flash drive that contains everything you need to install the 64 bit version of Windows 7.
