SGA_TARGET and / 3 GB switch

Hi all

We have Oracle 10g R1 installed on Windows 2003 Server Standard Edition SP1 with 4 GB of RAM installed.

We want to implement the/3 GB switch in the boot.ini file in Windows to increase the memory available for Oracle to 3 GB.

My question is: If I implmement the/3 GB switch, is still possible to use and set the SGA_TARGET?

Some people claim that I should turn off the automatic memory management and manually set areas for the buffer cache and the cache of the library.

I searched on the net and most of mixed articles this issue with AWE (Address Windowing Extensions). I do not implement the FEAR here, I just want to use the 3 GB of available RAM.

Thanks in advance.

You can then play very close to the error-prone area. I presume that you have arrived at these figures after some calculations and look ups.

To my knowledge, he leaves 400 MB to other applications and virtually, we have installed only Oracle and its control of database on this computer.

Lol its one by the process boundary. When you set the/3 GB switch in boot.ini, each process running on the system has the right to have the 3 GB address space. So if you have any other memory hungry/application running process, your body will suffer because of the RAM limitation physics and subsequent Exchange.

    Contact your carrier and make sure that your account is configured correctly. Then go to settings/general/to comments and press the network name; This will cause the exceptional carrier updates to install (you will see a dialog box saying if an update is needed). In addition, go to settings/general/reset - Reset network settings if none of these fix. You will lose the WiFi passwords, but nothing else.

    You can not. There is no method to remote turn on/off all the settings on the phone. The only thing you can do is put it in mode lost through the computer and it remains to be seen if the device connects to a known Wi - Fi network. Otherwise, you'll just go out and pick up the old-fashioned way. You have it in Mode plane, or you just disable cellular data?

  • Re: Equium L40 - Windows 7 and the wireless switch

    I upgraded my Equium L40 to Windows 7 and now, wireless equipment and F8 function switch switch the WLAN on and outside. It is permanently.

    Also, even if it is enabled in the Windows 7 power options, close the lid won't be thecomputer to sleep. If I close it turns off the screen but doen't make Windows 7 options.

    When I upgraded to Windows 7, I chose the option to do as a new installation and therefore lost my Vista installation.

  • OK to mix 'of connection to the switch"and"close relay switch?

    Hi all

    I'm developing a test sequence using the card multiplexer 2527 to the track signals.  To configure the card, I use DAQmx switch functions.  In my application, I have a Subvi routine that imports the data from a spreadsheet Setup and run a loop for to set the configuration for each step (each iteration of the loop contains the channel for 2527 card information).  The topology is set on the first iteration, as well as the configuration of the path to the first string.

    My concern is this: I need to close the extra channels/relays without changing the topology or resetting the device.  In the first round, I use "connection to the switch" function to set the initial path, (ch0 to com0 for example).  Then in subsequent iterations of the loop, I use "Relay close switch" function to close the additional channels individually (for example k2).  In the end, when the measure is taken, both ch0 ch2 must be closed and routed to com0.  This implementation is so sure, or am I somehow to make the adjustments to the initial loop?

    I would like to test this with the hardware, but it is not yet available.

    Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer.

    Please notify.  Thank you.

    Hello GSinMN,

    It's OK to mix 'of connection to the switch"and"Close relay switch"If you understand what's happening below. "Switch Connect" connects two channels by closing a path of relay between the channels, then "Close relay switch" can be used to change the State of the individual relays. If you are not careful you can mess up your connection by activating / deactivating relays that are part of the route connecting your channels.

    "Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer."

    I would recommend the topology independent if you want to stick with connections to channels only. http://zone.NI.com/reference/en-XX/help/375472G-01/switch/2527_independent/

    Initial connection:

    CH0-> pcom0

    pcom0plus-> icom0plus

    pcom0minus-> icom0minus

    icom0-> com0

    In each future iteration just connect to the next to pcom0 channel (which will be indirectly connect it to com0):

    CH1-> pcom0

    CH2-> pcom0

  • Increase SGA_TARGET and SGA_MAX_SIZE

    Oracle Version: 10.2.0.4
    OS: Windows 64-bit

    Hi s/n,.
    I want to perform under task
    increase the size SGA_TARGET to the other 3 where 1 GB is allocated to the shared pool and 2 GB for the buffer cache. () Our SGA_MAX_SIZE = SGA_TARGET)
    kindly share your thoughts on the points below:
    is there Ant limited with size SGA_TARGET with 64-bit as 4 GB with 32-bit system.
    Is there any negative impact on the database when we increase size SGA_TARGET and SGA_MAx_Size
    is there a relationship between RAM or between RAM and SGA_TARGET and SGA_MAX_SIZE.
    Thank you...

    H,

    Is there any Ant limited with size SGA_TARGET with 64-bit as 4 GB with 32-bit system.

    See
    Windows memory configuration: 32-bit and 64-bit [873752.1 ID]

    Is there any negative impact on the database when we increase size SGA_TARGET and SGA_MAx_Size

    the SGA_MAX_SZE parameter is not dynamic in oracle 10g.

    To increase the size of the sga for your instance or down,
    1. make the entry in the pfile as sga_max_size = value. (usually pfile reside in "ORACLE_HOME\database") *.
    2 judgment of the DB
    3. start the PB with the file pfile as "SQL > STARTUP PFILE = 'path of the pfile edited'"
    4. your DB now works on pfile, to make the changes to spfile "SQL > CREATE SPFILE = 'path of the spfile' OF PFILE".
    5. immediate stop
    6. launch of the DB with the newly created spfile "SQL > STARTUP SPFILE = 'path of the spfile'"
    7 sql > show parameter LMS to verify your changes take effect
    8. you may need to increase the value of the parameter SGA_TARGET if it has been set. Its a dynamic parameter and can be changed by the ALTER command.

    * If you do not have a pfile file and then create a pfile file by "SQL > CREATE PFILE ="the pfile file path"OF SPFILE.

  • I understand SGA_TARGET and SGA_MAX_SIZE well?

    Let's say that I updated SGA_TARGET and SGA_MAX_SIZE 1024Mo 512 MB.

    As I understand it, this means that the total size of the SGA will never exceed 1024Mo (it's the "hard cap"). Oracle will try to keep things around 512 MB, but can explode up to 1024 MB, depending on the needs.

    Is this correct? Otherwise, I don't see the point of SGA_MAX_SIZE SGA_TARGET vs.

    BTW... I know that MEMORY_TARGET and MEMORY_MAX_TARGET are the new 11g params, but Oracle XE comes with those turned off and the 10g SGA_ * params and PGA_AGGREGATE_TARGET updated...?

    It is not correct.

    This means that you can increase up to SGA_MAX_SIZE SGA_TARGET without having to bounce the database.
    Also Oracle won't increase SGA_TARGET, it will just make sure that the sizes of the different basins do not exceed SGA_TARGET.
    You are still responsible for the management of SGA_TARGET.

  • SGA_TARGET and SGA_MAX_SIZE how to set minimum for pools

    Hello, we are on 10.2.0.4, Solaris 5.10. We use the EAMA, both SGA_TARGET and size SGA_TARGET are defined. Therefore, cache buffers, shared pool, large pool and pool of java are sized automatically. However, we have not all minimum values for people. How can I determine what should be the minimum value?

    Thank you!

    Hello
    To get the best of the EAMA, should be set to 0 and let the oracle to decide how many SGA_TARGET it distributes between the memory structures according to the load.
    If you really need the size of a minimum value, then this value is considered to be the minimum limit that is to say if you size db_cache_size = 1 g then it would be the lower limit. Then Oracle would be able to reduce db_cache_size up to 1 g.

    Size, use of commands such as:

    SQL > alter system set db_cache_szie = g 1 scope = spfile;

  • sga_target and sga_max_size tips

    Hello

    ABT a little my current system

    HP UX 11.11 oracle 10.2.0.4 EBS11.5.10
    memory 4 GB
    2 GB SGA

    I will increase to 20 GB physical emory today

    I need advice on implementing sga_target and sga_max_size

    currently my SGA_MAX_SIZE = 2GB

    If you increase the physical memory, and then set the SGA_MAX_SIZE max size estimated, based on the use of applications and keep the SGA_TARGET to any value you currently have.

    This will increase the SGA dynamically (SGA_TARGET) when the office application need and you no need to stop your database.

    It is always advisable to keep SGA_MAX_SIZE > SGA_TARGET.

    I hope this helps.

    Kind regards.
