Resource Manager do not limit CPU acitvity 10G?

I have set up a resource plan to manage the use of the CPU. After doing this plan
active, I tested and the results were next: session passed to the lower category
with only 2% of CPU, but when I checked the CPU it State show 100% charge.

Question: Why this sessions have all CPU and not only 2% as it defined in terms of resources?

Plans of resources only manage CPU allocation when multiple sessions are running and the resources are fully utilized, if a single session is active and has been attributed to a resource group containing 2% CPU, can be used 100% of the CPU unless something else is running, it is logical that we can not save cycles CPU for later.
If you have two sessions is allowed 2% other 98% and the two are linked and then resource Erzberg will manage resources, as expected, at the UC

  • Support for transactions in the specified file system resource manager is not started or has been stopped due to an error

    We are running Vista Business and have problems as above on one of 40 computers.  We run all the same software on all machines, but are havving the same problem on this one computer. I searched all the other software of the same error message and that you are getting the same error on any software that tries to use a calendar for the implementation of various reportoire.  I used all of the suggestions, but so far nothing has worked.  We have Vista Business SP 2 and all updates have been installed?

    I wanted to just close my question with what I did to solve my problem.

    First of all, I took a double machine and downloaded a backup with all the files needed on this subject.  Then I did a Windows Easy Transfer from the old machine to the new machine.  This copyed concerns all the email and settings to the new computer.  I tried everything and everything worked corectly now, so I did a full image backup and restored to the original machine.  Now everything worked on the original machine.

    I don't always have the original problem fixed as I wanted to, but I just did what I had to do to get the system up and running without errors.

    Thank you.

    Please read doc links provided by Pavan above:

    By default, the resource manager is not enabled.

    The following statement in a text initialization parameter file enables the resource manager when starting the database and sets the top like mydb_plan plan.

    RESOURCE_MANAGER_PLAN = mydb_plan

    If you get an empty value of:

  • limit of cpu resource manager problem

    Hello world

    I'm testing the resource limit of resource manager. in all the documents I read, after you create groups of consumers, if I gave a resource limit in terms of resources, it is said, this group of consumers won't be able to consume more cpu than that. for ex, 2 consumer group I have one of them gave 90% of cpu and the other (let's call it test_group) 5%, but when I connect with a user who is located in the test_group consumer group. After the execution of some sql/plsql, I noticed that it uses all the cpu.

    EDIT: to the fifth message there is all the code samples and the test results with screenshots.

    for ex in this page: http://pic.dhe.ibm.com/infocenter/mdm/v10r0m0/index.jsp?topic=%2Fcom.ibm.mdmhs.smpl.gd.doc%2Fr_oracle_db_resource_manager_working_example.html

    There is a code example that explain the plan. It is said REPORTING_GROUP is not being able to occupy more than 5% of CPU times in total. I used this code, but reporting_group always be able to consume all the cpu. I tested this code (also I have created a new group and the plan of Enterprise manager) on windows 7 64-bit, intel i7 cpu with 4 core and on the same machine, using the virtual machine oralinux. as database, Enterprise edition 11.2.0.1

    also resources plan is active and working, active session limit or cancel hen size for example, works when I tested it, but CPU limit is not. for testing I used the plsql code.

    create or replace function sf_test(p number) return number as
      x number;
    begin
      select 1 into x from sh.sales where prod_id = p and rownum = 1;
      return 1;
    exception
      when no_data_found then
        return 0;
    end;
    /
    
    
    declare
      x number;
    begin
      for i in 1..50 loop
        for i in 1..10000 loop
          x := sf_Test(i);
        end loop;
      end loop;
    end;
    
    

    I created four session of the Report1 user (in the link I mentioned before) and run this code plsql, at most 5% of cpu if they had but my CPU is overloaded almost every time.

    I missed something here or I got all wrong concept?

    PS: setting resource_limit is true and resouce_plan is the plan that I created. as I said before the plan is active and functional, I know, but may not limit the cpu. I would appreciate it if you help. Thank you very much.

    Looks like the resource manager behave correctly.

    If the session manager are not ask for 95 percent of the CPU resources, what remains will be the users of the report.  Oracle will not starve the UC report sessions if there are a bunch of CPU idle.

    If there are 8 Virtual cores and a bunch of single threaded sessions, you need at least 8 sessions before Manager the Manager could use 95% of the available CPU.  Most likely, you would need 9 or 10.

    If you have only a 6-wire Manager, these discussions could consume at least 6/8 = 75% of the available CPU but probably more than 67% (to pick a number that facilitates the calculation).  There is 33% of the CPU for the report.  There are 4 sessions of report in your screenshot with a little more than 2 cores available and each one seems to spend slightly more than 50% of their time on the CPU, which looks all right.

  • The CPU used by the resource manager.

    Hello
    in 10g R2, I created a Plan for DBMS resources manager:
    EXEC DBMS_RESOURCE_MANAGER.CREATE_PENDING_AREA();
    
    EXEC DBMS_RESOURCE_MANAGER.CREATE_SIMPLE_PLAN(SIMPLE_PLAN => 'simple_plan1',CONSUMER_GROUP1 => 'mygroup1', GROUP1_CPU => 80,CONSUMER_GROUP2 => 'mygroup2', GROUP2_CPU => 20);
    
    
    ALTER SYSTEM SET RESOURCE_MANAGER_PLAN ='simple_plan1';
    
    
    
    EXEC DBMS_RESOURCE_MANAGER.SWITCH_CONSUMER_GROUP_FOR_USER ('SCOTT', 'MYGROUP2');
    EXEC DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP ('SCOTT', 'MYGROUP2', TRUE);
    
    
    EXEC DBMS_RESOURCE_MANAGER.SUBMIT_PENDING_AREA;
    
    EXEC DBMS_RESOURCE_MANAGER.CLEAR_PENDING_AREA;
    Now, SCOTT runs the following (example from 24 through the database manager):
    DECLARE
    m NUMBER;
    BEGIN
    FOR i IN 1..100000 LOOP
    FOR j IN 1..100000 LOOP
    /*

    And CPU use goes to 100%. Why? According to its consumer group should not only have 20% of CPU?

    No explanation?
    Thank you.

    Hello

    user522961 wrote:
    And CPU use goes to 100%. Why? According to its consumer group should not only have 20% of CPU?

    A quote from docs explained:

    The currently active resource plan does not have the limits of the allowance until the CPU usage is 100%. If the CPU usage is less than 100%, the database is not related to the CPU and there is therefore no need to enforce limits to ensure that all the sessions to get their allocation of designated resources.
    In addition, when the limits are applied, allowance unused by consumer groups can be used by other groups of consumers. In the previous example, if the SALES group does not use all of his allowance, the Resource Manager allows the group to MARKET or DEVELOP it group to use the unused allocation.

    As far as I KNOW, the SSDS should be visible as "local". You can run the command.esxcli storage core device list -d   and check if the device is showing as local ssd

  • Question about the Oracle database resource management

    Good evening
    I have a question about Oracle database Resource Management (DRM) for Oracle Database 10 g. I had an incident which, in a development/UAT environment (different instances, same box, don't ask), a developer wrote a wrong SQL statement that consumed 99% of the CPU. Currently, there is no limit of resources on two cases of db, and the developers don't want limits. However, my manager wants a method to prevent something like this does not happen. If I use the Oracle database resources management, create a consumer group (called "DevEnv") at 40% CPU usage, what will happen if a user of DevEnv runs a bad SQL statement that normally consumes 90% CPU again? Anyone would take a different approach? Thank you.

    Sincerely,

    Yes, because the available processor would be 40%, they use more, while.

  • Priority OLTP application using Resource Manager

    Version: 11.2.0.3
    Operating system: Solaris 10

    We have an OLTP application that is busy almost 24 x 7. The night 23:00, a batch begins and usually ends by 04:00 in the morning. Lately, our OLTP application has become slow due to this particular task. We need to give less priority to the lots that we don't mind lie until 07:00 in the morning. So, I do a bit of research on the implementation of resource manager.

    I think that limits based on the "Consumer groups" are created according to the drawings. But, the OLTP and batch processing to access the same schema (named FCDN01). So, how can I limit the use of the CPU and the RAM of the batch work session accessing the schema FCDN01?

    http://www.Oracle.com/technetwork/database/performance/resource-manager-TWP-133705.PDF explains how you can use a separate service for the batch, or the particular to a batch oriented resource session.

    However, if your problem is, say, oltp and batch, objects blocking processes or otherwise disturbing each other, this can slow down the two. If you are better off to understand the real question, then solve that.

  • For windows 98 Resource Manager

    Hello

    I'm working on the restoration of material capacity old test using some spare disks.  I'm looking in the resource Configuration Manager, and I am puzzled.

    I'm looking in the resource manager is National Instruments MAX (Version 2.0.3.17).  What has intrigued me is that, under the 'devices and Intersfaces', I don't see any instrument listed under.  Windows hardware Manager, I would have two ISA Serial Port and a GPIB card (which is also ISA).

    MAX isn't supposed to list these instruments?  Do I need to add the instrument manually?

    And, is this version of resource manager works fine with Windows 98?

    Any help is appreciated!

    Thank you.

    Peggy

    Hi Peggy,

    If you have not all devices listed under "Devices and Interfaces", I suspect that you have not yet installed the drivers, or the device loader is not started.

    You have NEITHER-488. 2 (GPIB) and NI-VISA (serial ports) installed the drivers? You can find the drivers here , but you will have to go back a few pages to find drivers compatible with Windows 98.

    When you confirm that you have installed the drivers, I'll be happy to dig deeper with you. Thank you!

  • Device Manager does not not in Vista Home Premium 64

    Well, I tried to help others in the hardware section so maybe someone here can offer some advice for me.

    I'm running Vista 64 Home Premium on a dv9700.  For more than a year the Device Manager did not work.  Everytime I try to open an error window appears which says "mmc.exe - bad Image".  I also have a similar error window when I try to open MS Paint and several other utilities like the option "Manage" when I right click on my computer.  In the fault window is a big red X and it says: "C:\Windows\System32\odbcint.dll is not designed to run on Windows or it contains an error.  Try to install the program by using the original installation media or contact your system administrator or support software provider. "In the case of MS Paint, he says"mspaint.exe - bad Image"at the top of the window of the fault, although he then gives the same extended error description as above.  I think that the root cause of all this might be a bad odbcint.dll file, regardless of who is.

    The problem has existed for some time, but I would like to be able to reuse my device manager to check the dates on the drivers and things for updates.  I know I could probably use the system recovery option, but I prefer not to return to the factory default state and having to reinstall all programs, I've added since I bought this computer almost 3 years ago.  Windows used to have a repair option that would repair the system files without deleting the installed programs.  I can't find that on Vista.

    I have already run the SFC/scannow utility from the command prompt at the level of the system administrator.  It passes through the system for a long time and then says it finds corrupted files, but could not solve some of them and go to CBS. LOG file for more details.  When I try to open this log file, it says: 'access denied', even if I have the system administrator access level.

    Someone at - it give me advice without having to restore everything to default "as shipped"?

    Thanks for the link DLL Vista d/l.  I didn't know who was available.  I downloaded odbcint.dll which the fault indicates that this file is either damaged or missing and replaced him in the windows/system32 directory.  Also, I did the same with the file mmcndmgr.dll you mentioned.  I get always the fault of odbcint.dll every time that I try to use the devices, MS-Paint, manage and probably several other things that I have not tried.

    It seems that the only option is to restore the system to default if I want to get this working again.  So during my research, I learned that the downgrade to an older version of Windows is free.  I wanted to sort of go back to Windows XP from Vista 64 that accompanies this laptop since I got it.  I have a Windows XP Pro installation disc that I bought for my desktop PC and all I would need is a free Microsoft activation key which told me they would provide decommissioning.

    However, the support section driver and software for Windows XP here on the site Web of HP has rather limited resources compared to the options for my dv9700 Vista CTO.  On the one hand, there is no graphics driver listed.  I know I probably d/l anything directly form the nVidia site, but this is not the only driver XP or absent utility of the product support for my computer page.  I guess I'll probably use just the recovery Vista DVD that I made when I got my laptop, if I decide I want to do this.

    A F11 recovery that accesses the Recovery Manager in the laptop's recovery partition would be a good plan. When a Windows operating system beghins to exhibit behaviors such as yours is so it's just a matter of time before is no longer, it will start up in Windows.

    I recommend that you create a CD to recover fees just to have the value.

    It is actually faster and more reliable to perform the recovery of the Recovery Manager in the recovery partition from the wear of your DVD drive and recovery CD set since the purchase of your laptop.
