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
/*
* The following query does a cartesian product without
* a predicate and takes up significant CPU time.
*/
select count(*) into m from v$sysstat, v$system_event;
END LOOP;
END LOOP;
END;
END;
/
And CPU use goes to 100%. Why? According to its consumer group should not only have 20% of CPU?

No explanation?
Thank you.

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.

  • How to see the a ditamap topicrefs nested in the resource manager?

    Hello

    I use 12 FM. I'm trying to move a document of 500 pages with several chapters in Dita 1.2. I use a ditamap by chapter. When I nest ditamaps under a main ditamap using maprefs, I do not see the topicrefs of each card. Also, the subjects are not displayed when the PDF is generated. How can I make all the topicrefs appear in the resource manager?

    Thank you

    Stéphane

    You do not see the topics in the section maps form the root card. When you open a map, you see the topicrefs for this card not the submaps. If you want to see the topicrefs, double-click the map reference and it will open the plan of the chapter. Maybe it's an interesting feature, but it doesn't currently work in this way. If you want to see all the topicrefs together, you will need to put them all in a single card.

    The issue of topics in submaps are not included when you generate a PDF file sounds like a bug (or you have something set wrong). You can try to change the maprefs to topicrefs. A mapref is really just a special type of topicref, and the build process cannot be put in place to manage maprefs.

    See you soon,.

  • RH10: Excerpts from the Resource Manager display in search results

    I'm new to using Resource Manager, so there is a good chance I did something stupid here... but...

    I have 2 projects (I am the only author of technology, so running off a PC, any version control). I want to share snippets of code between projects, so I use the resource manager to keep them synchronized to the top. Both are compiled as CHMS.

    When I search, I get search results that appear to be the code snippets in the results. When you double-click on them, they do not open.

    Here is a screenshot of what I see.

    Has anyone else seen this before? I use RH10.

    I found it finally... somehow some of my clips appearing in the results of the research had found themselves in the baggage files. I had foolishly made express at some point in my project or not I have no idea. But the baggage of ditching apj file and replace it with a vacuum has solved the problem.

  • Sessions are not assigned correct consumer to the Resource Manager groups

    Hi all

    I have a number of consumer groups that I attributed to users:

    USERNAME INITIAL_RSRC_CONSUMER_GROUP

    ------------------------------ ------------------------------

    RM_BOGEY0 SYS_GROUP

    RM_BOGEY1 S/N

    RM_BOGEY3 DAAS_PLATINUM

    RM_BOGEY4 DAAS_GOLD

    RM_BOGEY5 DAAS_SILVER

    RM_BOGEY6 DAAS_BRONZE

    RM_BOGEY7 DAAS_LOW_PRI

    RM_BOGEY2 DEFAULT_CONSUMER_GROUP

    My understanding of the present, is when a user connects they are assigned to this group of consumers.

    However, this is not case.

    When the user connects they are attributed to OTHER_GROUPS

    SQL > SELECT SID, SERIAL #, USER name, the RESOURCE_CONSUMER_GROUP OF GV$ SESSION where RESOURCE_CONSUMER_GROUP! = USER name and "_ORACLE_BACKGROUND_GROUP_" like '% RM_BOGEY ';

    SID, SERIAL # USERNAME RESOURCE_CONSUMER_GROUP

    ---------- ---------- ------------------------------ --------------------------------

    RM_BOGEY5 3 499 OTHER_GROUPS

    RM_BOGEY6 196 295 OTHER_GROUPS

    RM_BOGEY0 197 433 OTHER_GROUPS

    RM_BOGEY7 294 883 OTHER_GROUPS

    RM_BOGEY1 868 189 OTHER_GROUPS

    1253 81 RM_BOGEY2 OTHER_GROUPS

    1351 25 RM_BOGEY3 OTHER_GROUPS

    1445 481 RM_BOGEY4 OTHER_GROUPS

    I can change consumer groups by running:

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY0", "SYS_GROUP");

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY1", "S/N");

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY3", "DAAS_PLATINUM");

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY4", "DAAS_GOLD");

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY5", "DAAS_SILVER");

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY6", "DAAS_BRONZE");

    exec DBMS_RESOURCE_MANAGER. SWITCH_CONSUMER_GROUP_FOR_USER ("RM_BOGEY7", "DAAS_LOW_PRI");

    And then everything is as I expect to be, but I do not understand why the groups are not be correctly assigned at login?

  • 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.

  • name of the resource programmatically

    I'm trying to get the name of the resource 'PXI1Slot2' PXI programmatically.

    How to get the handle whch viGetAttribute() object requires?

    viOpenDefaultRM (& rsrcHandle); Returns ViSession.

    Is there an attribute to get the number of accommodation?

    int CVICALLBACK FindResources (int, int int event, control panel,
    void * callbackData, int eventData1, int eventData2)
    {
    ViSession rsrcHandle;

    {
    case EVENT_COMMIT:

    First of all, log VISA.
    viOpenDefaultRM (& rsrcHandle);

    Now, to do an initial search. viFindRsrc returns the descriptor of instrument
    the first found instrument and the number of total resources found.
    viFindRsrc (rsrcHandle, "?") * PXI? * INSTR", & MyFindList, & %%numFound%% shops, InstrDescriptor);
    viGetAttribute (rsrcHandle, VI_ATTR_PXI_CHASSIS, frame);

    When you are finished, close the VISA session.
    viClose (rsrcHandle);

    break;
    }
    return 0;
    }

    According to the function panel, the object handle is a unique logical identifier for a session, list to find or event. So ViSession should be OK. But it seems that rsrcHandle is a session to the resource manager. You will need to use ViOpen to establish a connection with your device.

  • 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!

  • Command line and Resource Manager

    When you use the command line to compile a Robohelp project, is it possible to update the resources shared within the project before generation?

    For example, you have Project1 and uses snippet1 in this project. However, snippet1 has been changed in the Resource Manager (just say, for the sake of argument, that snippet1 is also used in Project2, and you changed the extract it and it synchronized to the Resource Manager). When you do a regular command line compilation, the extract is not updated.

    Is it possible to synchronize the excerpts and images from the resource manager in the project before proceeding with compiling from command line (other than opening the project and sync manually)? After all, if I have to open the project, there is no reason for the compilation command line since I was already there and can just compile the project.

    Thank you!

    I found a way around this!

    RoboHelp does not care if the files are updated through the application or through Windows Explorer (such as copying the latest file in the project folder).

    I created a simple batch file copies and replace any file that is older than the file that is located in the resource manager. This allows RoboHelp pull into the updated files in a command-line compilation. There is always a way!

    However, I found something problematic with the command line compilation. I started a new thread to ask about it.

    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
