How to increase the SGA

Hi all

Oracle 9i

We have a database of PROD that has the performance issue.
Our Production Linux server has 12G of physical memory.
My boss told me 6G memory allocation to the database.

I therefore change our init.ora and set TARGET_SGA = 6G

But when I restart our database and the SGA VIEW, it shows only 700 MB.
What are the parameters in init.ora I should increase to give me 6G SHOW what CMS?


Thank you very much.

SGA_MAX_SIZE large integer 715724556

You can more than double existing value.

Realize that 2 GB is the largest positive integer that can be represented in 32 - bit; That is why the max 1.7 GB on SGA.
Oracle had to book the little extra space for non - SGA memory resident data structures.

    So what! People always complain that the apps are slow. While it's good to take note of that do not have a reflex reaction to it.

    Gather more information.

    1 slow down what? data entry? running reports? batch?

    2. slow when? first thing in the morning? in the middle of the day when users are on the system? All the time?

    3 How long have you slow? It all started? A few days? a few weeks ago?

    4. that means the main DBA say about the slow reported? You have called to ask? Why not? They are on maternity leave not climbing the Alps or the Himalayas. Call them and ask them they were aware of the reported problems.

    5. have you asked the Chief EXECUTIVE what should you watch? Why not?

    Tell us more information. What are the parameters of memory now?

    This old laptop has a graphics card with shared memory. In other words, when you have more RAM inside more memory will be used for graphical operations. According to the specifications of the laptop this old notebook was shipped with 128 MB of RAM, but can be improved up to 512 MB.

  • Satellite A300-18 has: how to increase the screen resolution

    I have recently buy a Toshiba Satellite A300-18 a, and I want to increase the resolution of the screen.
    Currently the max resolution is 1280 x 800.

    Does anyone know how to increase the resolution?
    Where can I find the drivers to increase?

    Thank you

    Henrique

    Hello

    I don t think a new graphics driver would allow a higher screen resolution on your laptop A300.
    Have you checked your manual for more details?

    I downloaded the user manual of the Europe of Toshiba page and discovered that the display is a 15.4 WXGA 16Mill colors with the following resolution: 1280 horizontal and 800 pixels vertical.

    It seems that you are already using the highest available resolution and therefore you will not be able to wear to higher values.

  • How to increase the sampling rate in this VI?

    Hi all

    I have recently inherited this mess of a VI and can not figure out how to increase the sampling rate. I tried to change the "ms of waiting ' clock, but it does not add more data points." The main VI, as well as the Subvi, which contains a Daq Assistant to a load cell and LVDT is attached. Any ideas on how to improve the sampling without a complete overhaul would be greatly appreciated!

    Thanks in advance!

    One thing that can help is a bit what follows.  Do a right-click the speaker icon in the taskbar and select "playback devices".  Left click the device once to highlight default (it is usually 'speakers & headphones') and then click the properties button.  Click the enhancements tab and put a check mark in the box "Loudness equalization.  Click on apply to save the changes and then click OK in all other windows and see if allowed at all.

  • How to increase the speed of the PC without adding RAM

    PLEASE HOW CAN INCREASE THE SPEED TO RUN THE PC WITHOUT ADDING MORE RAM

    Some reasons for the slow pace of the computer:

    1. computer has not been maintained - http://www.elephantboycomputers.com/page2.html#Maintenance

    2. the computer is infected with the malware - http://www.elephantboycomputers.com/page2.html#Removing_Malware

    3. the disk is too full. Remove useless stuff, uninstall unused programs. Do not forget to save!
    http://www.elephantboycomputers.com/page2.html#Backing_Up

    4. flaky third party software. Toolbars and modules are particularly guilty in this area. Uninstall toolbars (Google, Yahoo, ISP brand, etc) and look at what modules are in use in your browser (s).

    5. computer has too many unnecessary programs/processes running in the background. Manage your Startup:

    For XP - How to troubleshoot using the Msconfig in Windows XP utility - http://support.microsoft.com/?id=310560
    The free Autoruns program is very useful for managing your Startup - http://www.microsoft.com/technet/sysinternals/default.mspx

    For Vista/Windows7 - Start Orb > Search box > type: msconfig and when it appears in the results area above, right-click and choose 'run as administrator '. Autoruns is also very useful.

    6. the user runs an inflated/invasive such as Norton and McAfee antivirus program. Replace it with a better program. I recommend NOD32 (commercial) or Avast (free). Avira is also good, but the free version has an unpleasant reminder screen (Google for instructions on how to disable it). The user can also run several real-time antivirus/firewall/security programs.

    7. the user has installed new programs that are processor and/or memory-intensive (Photoshop, AutoCAD, Mathmatica or similar) and does not have the power of the equipment.

    8 drive fails and is in PIO Mode. It's very much slow (like being in 1985). See Hans-Georg Michna here information - http://winhlp.com/?q=node/10

    In addition to the above, see also http://miekiemoes.blogspot.com/2008/02/help-my-computer-is-slow.html

    Note: If the computer has always been slow, in addition to the above user may have bought a machine with a less powerful processor and not enough RAM (memory). The normal use of the computer, 512 MB to 1 GB is sufficient for XP; Vista should have a minimum of 2 GB; Windows 7 is less demanding than Vista, but the minimum of 2 GB should also be used.
