Help to understand the plan of the explain command

Hello world

I have a question:

INSERT INTO ICM_UPSEL_1_ALL

Select a.customer_no, a.pr_code_bbl, pr_code_pmm, a.score, a.price_diff, a.flag (b.pr_code_pmm) min

ICM_UPSEL_MIN_PRDIFF_1 a, icm_pre b

where a.customer_no = b.customer_no

and a.pr_code_bbl = b.pr_code_bbl

and a.score = b.score

and a.flag = b.flag

and a.price_diff = b.price_diff

and b.price_diff > 0

and b.score > = 0.5

and b.flag = 1

and b.price_diff > 0 and b.price_diff < = 10

Group of a.customer_no, a.pr_code_bbl, a.score, a.price_diff, a.flag

This query runs in a pl/sql procedure.  The plan of the explain for this query command is:

This query runs for 10 hours now and still no results.  Could someone please help me where goes wrong... Why is - it take as long to insert data...

The number of rows in ICM_UPSEL_MIN_PRDIFF_1: 84 858

The number of rows in icm_pre: 455,500,944

All columns are indexed.

My version of the database is 11.1.0.6 running on windows server 2003 R2.

Thanks in advance

This plan seems much more suitable for me: instead of doing > 80 K of the loops of the CBO now decides to make a unique HASH JOIN. I would try to run the operation with the dynamic_sampling flag. If the system statistics are not completely misleading the operation now only takes a few minutes (and no 10: 00 >).

    It exists (select 1 from sub_services

    and so_id = 'A09.

    but don't know why he's back 7 files, can someone help me understand the result...

    It is query is functionally identical to the PL/SQL block, but much more effective.

    declare

    number of l_res;

    Start

    for line (select *)

    sub_services) loop

    Start

    Select 1 from l_res

    of sub_services

    exception when

    NO_DATA_FOUND then

    null;

    end;

    end loop;

    end;

    Essentially every row in the outer query are tested against him exists query.  Given the correlation between two requests is based only on su_seq each line with a su_seq value returned by him is returned in the output.

    Another way to think he uses instead a join condition.  This query is equivalent to the query to exist

    Select the main

    of main sub_services

    Join select (separate su_seq

    of sub_services

    where so_id = "A09") cond

    We main.su_seq = cond.su_seq;

  • Need help to understand the network of vSphere environment

    Hello

    I need your help in understanding the network environment in vSphere. Please see the diagram and the text below:

    vm.png

    NIC #1 - Management Port (access from client vsphere, vCenter server)

    NIC #2 - Port of VMkernal (for iSCSI, vMotion, etc.)

    NIC #3 -?

    #4 – CARTE NETWORK INTERFACE?

    Q1 how allow external users to access services over the ESX host? (for example, IIS, FTP, Exchange, NFS)

    Q2, what will be the role of the other two network cards? Is it connected to the physical switch?

    * Ask you all to please help me by sharing your knowledge / experience on the network portion, you have made in your environment as NIC how, what to do with that. *

    I really need to understand the networking of concepts in vSphere, hope that your help!


    Best regards: Yash

    With an additional NIC with 2 port a general configuration might look like this:

    vSwitch0 - vmnic0, vmnic1 (connected to different physical switches)

    Network VMkernel management

    VMotion VMkernel network (own IP network, own VLAN)

    Better if they is configured as active / standby.

    vSwitch1 - vmnic2, vmnic3 (connected to different physical switches)

    Trade VM

    vSwitch2 - vmnic4, vmnic5 (connected to different physical switches)

    VMkernel iSCSI (own IP network, own VLAN)

    Ideal if it is added to the component Multipath iSCSI, which is quite easy to vSphere 5.

  • Need help to understand the collection

    Hi all

    I'm trying to understand the concept of collection, but when I look in the documentation that exists in google.ca, then, it seems very confusing. If someone suggest me or send me some simple examples and good collection and I really appreciate it. Thanks in advance.

    Concerning

    Line

    Thanks for the explanation, could you please explain what does really to take care of the index as a whole and clause varchar2 and if yes then what condition we use varchar2 index and in which condition we use index as a whole, be we just use index by integer in our daily practice. Really appreciate your response. Thank you

    Generally if you use collections, especially PL/SQL-only collections, your architecture is probably wrong. Collections are rarely necessary, but are often USED in the mistaken belief that they will help performance.

    The use of the collections usually DEGRADES performance, sometimes severely, and they are often used in a way that is not scalable. You should avoid using collections if possible.

    So don't use the collections AT ALL in your 'common practice '.

    For the rare cases where there is to use an array associative index type to use depends on the data type of the element that you will use for the index. If you plan to use a string, then you use INDEX OF VARCHAR2. If you plan to use an integer, then you use INDEX BY PLS_INTEGER.

    What type of index to use has NOTHING to do with performance.

    One of the WORST mistakes developers make is to use an associative array as target of a BULK COLLECT INTO instead of using a TABLE IMBRIQUEE. Collection in bulk is more often used in a FORALL statement so that the elements are accessible only in the order. Useds "indexed" access with associative arrays isn't even necessary or used.

  • Help me understand the Vista backup

    I just started using Vista backup to backup my PC to an external hard drive.  There are several things I want to ask about the Vista Backup utility.

    1. with many other backup programs (by example, utility backup Windows XP), I was able to review what files were backed up, because the utility has a provision for the display of files saved in their original folder structure.  This is useful for manual checking that a group of files have been backed up.

    With Vista backup, there is no provision.  The backup is stored in a number of ZIP files, with no apparent match to the source folder structure.

    Is there another way to view files saved in their original Vista backup folder structure?

    2. I recently did a second backup of my hard drive Vista.  I have added almost all the files.  In fact, most of the changes have been moving and renaming of audio files.  Yet, the second backup is larger than the first, each approximately 20 GB.  And it took a long time, like the first.  Ultimately, the TWO backups were kept in separate folders dated.

    My questions:
    a. Why is the second big backup?  Can I apply an incremental, or differential backup as it existed under XP?  If you tell me that it's already a differential backup, then why is it so important and take so long?

    b. I must keep each date of the backup folder?  If so, my external hard drive is quickly running out of room!  But if I remove it, maybe I'll lose data!  Please help me understand how Vista backups are cataloged.

    Thank you.

    The second backup is great because because you moved your files autour and so backup if they were different files. Vista backup only new or modified files after the first backup.

    If you open the file, you will be able to access all the saved files and delete those you don't need.

  • Help to understand the basics of the integration of Javascript/QML

    Hey all!

    I am just development of BB for the first time, so please bear with me. I'm not sure that understand the interaction between JS and QML. I understand that you can write JS in QML, particularly in managers of signals, and I used chunks of it with success. Also, I show/read by the "Javascript in QML" and JS linked in the pages of Qt, which helped a bit.

    However, I am having a few problems incorporating it into my code.  Could you take a look at this and point me in the right direction? (I'm also new to JS itself, so maybe that my mistakes are with this instead?)

    Thanks in advance! I feel I'm missing something incredibly small/basic

    try calling it without braces.

    You can also create a function directly in QML, no need to export to a js file unless you want to use other components (that are not subcomponents) as well.

    to learn more about the construction of Qt/QML parent, I suggest to read this doc API:
    http://Qt-project.org/doc/Qt-4.8/objecttrees.html

    createObject (this) would create a new component with the parent defined on the object class, and if this is destroyed a new is also destroyed. This is useful when you create components dynamically as you don't have to delete them manually later.

  • Can someone help me understand the process Instance recovery

    First thanks for all of you who responded to my post, any help is really appreciated.

    I would like to more deeply understand the Instance recovery process then the Administration Guide of Oracle Docs can tell me.

    What I have so far of Instance recovery is:

    1 oracle determines which files are not synchronized.
    2. all data from redo log files is applied to restore log buffers by progression. Buffers do not participate on the database of normal transactions because they are marked to pick it up.
    All these data are applied to the data files (commited and contains transactions).
    This step is called roll forward.
    3 cancellation are used to restore transaction no. After this step the datafiles not aura no data contains on them. At this point, the instance is available for users, but the blocks used are not.
    4. all files are now in sync.

    My questions are:

    -Step 1, what process determines which files are not sync? Make the bed of Smon the controlfile and data file headers and then make a list which is not sync?

    -L' step 2, what is the process that reads the information in the redo log files and complete the recovery log buffer? What is the CKPT? And how he is warned that he might start to read the files after completing step 1? There is a semaphore that is defined for it?

    -Step 2, which process applies information engaged and contains buffer redo log for the data files? When it starts to apply this information of the instance is already partially available to users?

    -Step 3, what is the process that reads up to cancel to restore transactions not? This process must be done once step 2 is complete as could be blocks of the undo tablespace on buffers of the right-wing newspaper do it again? And when this step 3 starts, the process is triggered by an another semaphore?

    -When step 3 is finished, what process changes the State of the database of partially open to open, or that's just what we call it when the database has always revenge marked for recovery?

    Thanks again in advance for the help, there are reasons not practice known this information, I'm just a curious person who could not find this information on the google...


    Ricardo Rodriguez

    Ricardo,
    Well, I'll take a chance to respond.
    (1) SMON in the start-up phase, in the strict sense in the editing phase, compares the SNA stored in the control file with the data file headers. This sCN is called checkpoint SCN. It is always higher among the controlfile so its part of the same database and is not set up to an old backup. By this correspondence, Oralce comes to know that there are some report files with their SNA control point is only not with the controlfile and consequently, instance recovery is reported. Here is the list of files is prepared.
    (2) the same process SMON only would trigger playback of the redo log files and launch the Rollforward process. Roll forward is made from the last address bytes redo controlled at the end of the restore log forward. This means that the last block, blocks have not reported in the data file are simply read and are dumped on the data files. As a result, we get a situation that the data file will end up with a lot of data committed but also committed that redo is containing both.
    CKPT process will not come in the picture I think. Where did you read what CKPT would do all this?
    (3) SMON governs all this thing is to say the application of the data for the data files. No, in this phase, we are still in the phase of mounting that this recovery is called crash recovery. Oracle wouldn't let users to use the database at this point. Data is still not available for them.
    (4) do not bring semaphores here. They are already in use when you allocated the memory of your instnace. Its work process level. After the mount phase is completed, oracle would open up the db. At this stage, "the transaction recovery" aka rear roller phase. That would be launched to relax all the operations that are not validated.
    Now to do this, undo will be used. Oracle launches this phase into two or more strictly speaking 3 ways. One, SMON would just check how many blocks will be there for the recovery. If they are larger, it would begin the rear roller with parallel slaves. This is called "we demand" rollback. It is initiated by the user. So if you were using the EMP table data and the server crashed between, now the next time you start, if you try to access the same blocks once again, they are set aside on the basis of priority.
    The third one will rollback transaction intra. It's basically splitting the work among the slaves so that if a slave is sitting free, it can share the work and can move forward to make things more quickly restored.
    Please note that all this is happening at the open stage. This means then that this is the case, oracle is available for users. And second, there is little change in this process (an integer) 9i go. This is called two-pass recovery which has been made to make this process a little faster. In this regard, SMON ignores these blocks that are controlled by DBWR during execution of the phase of rollforward.
    Hope this makes some sense and helps. Let me know if there is something wrong or unclear.

    I also have an index on the DVC_EVT_TYPE_CD column in my table (line 8 of the predicate information section)

    And finally, what would be your suggestions to improve the performance of this query...

    Thank you very much.

    If I read content (RowSource) statistical information and plan properly, then access the table in step 4 on D1_DVC_EVT_REL_OBJ needs dry 4.37 and accesses 820 buffers. If you had an index D1_DVC_EVT_REL_OBJ (MAINT_OBJ_CD, PK_VALUE1, DVC_EVT_ID) I guess this table access could be avoided. To avoid the access of the table on D1_DVC_EVT an index on D1_DVC_EVT (DVC_EVT_ID, DVC_EVT_TYPE_CD, DVC_EVT_DTTM) should be sufficient.

    I think that these indices would improve the performance of the query, but of course, they would have a negative impact on the performance of DML on the table and they could influence other queries on the table.

  • info of parallel execution in the plan of the explain command

    In terms of explaining it, he learns you if a query is running in parallel? If so, what parts give you information about parallel execution?

    a parallel plan contains a large number of obvious differences if compared to a corresponding series plan: you should see a few operations beginning with the prefix of PX. In addition, it is more difficult to interpret a plane parallel (at least for me). Randolf Geist explains the basics (and more) in his informative article: parallel understanding - execution part 1.

    link real =Oracle application development: how to dynamically populate a Pop list?

    Code

    DECLARE

    group_id RecordGroup;

    GroupName varchar2 (10): = 'abc ';

    status NUMBER;

    BEGIN

    group_id: = find_group (group_name);

    status: = Populate_Group (group_id);

    Populate_List('DUMMY.) TXT_LIST', group_id);

    END;

    Concerning

    Line

    POPULATE_GROUP is a function (not a procedure) and must be called in this way.

    State could be verified - see forms help:

    "After a successful query, POPULATE_GROUP returns a 0 (zero)."

  • Help me understand the use of background images in "parallax is Fun!"

    Hello!

    I'm new to Muse, and I'm breaking the Parallax is fun how was created. I've been watching the file of the Muse and the source of the page, and I can't understand how the background has been added. The image with the stars a single image file, for example, or the bottom of everything, with colors and gradients, all a long background image? Each of the colored rectangles is a fill, or they are part of a large background image?

    In my file of Muse, these images seem not to be a browser fill - filling browser just appears as gray for me in the room. But I don't know if it's because the assets came not with the file of Muse, or because I do not understand how background images have been added.

    Thank you!

    You are probably confused because you can't select rectangles is home, the stars and the colored background.

    Go to the object menu and click on "Unlock all on the page" to unlock all locked elements and after that, you will be able to select, move and individually control each object on the page. The stars is just a rectangle with a picture fill configuration.

    Hope that helps.

    See you soon,.

  • Please help me understand the problem installing Acrobat Standard Xl with C++?

    I have an error message: "Visual C ++ 2010 (x 64) Runtime missing: Insralling Acrobat via MSI will not install Microsoft Visual C++ 2010 (x 64) SP1 runtime." With this, some features of the application will not work. You can try to install using set.exe if not already done. Press OK to ignore and continue nevertheless or Cancel to stop the installation. »

    I went to the Adobe help page on this topic. I tried to install the Microsoft C++ via the link, and a message simply offers a repair, which I chose. That made no difference - same error message when I try to install Acrobat.

    I do not understand because I see that I tried indeed to install using setup.exe - according to the directives of the disc. I couldn't find the vc - red.msi in VC10RT_x64 to re - install...

    Can someone help me with what to do else? I'm not an irritable person, just someone trying to do things...

    Put the CD and cancel the automatic installer.

    Use Windows Explorer to examine the contents of the CD, find the Setup.exe and then run that. I don't know if that will fix it, but that's my point of view on what the message says.

  • Could someone help me understand the extension of component?

    I read a few chapters on the extension of component (using the EXTENDS attribute in the CFPROPERTY tag) but something isn't clicking; I'm looking on the forums for some additional info that will help me to have a eureka moment and understand.

    In preface, I have what I would call, an intermediate knowledge of CF (working towards the tip).  So if we can keep the explanations in simple terms as much as possible, it would be appreciated and useful.

    To my knowledge, if you have a component, you can make its variables in THIS scope and its methods available to other components if those components have an EXTENDS attribute in the CFPROPERTY tag that uses a full path point rating to the component 'extended-of ".

    I tried to put it into practice by making a master.cfc and Captain slave.cfc is located next to the root in a folder named "www".  The slave is located next to the root at the site: "www/app/comments.  In the slave.cfc component so I wrote:

    < cfproperty extends = 'www.master'...

    Assuming it was the same as the CF from the root of the Web site and the search in the www and then record seeing the master.cfc.

    But when the slave component I call a function that exists in the master, it says that it can't find it.  What I get here?  This sounds like a POWERFUL way to share variables of EC-scope of the application.cfc, so I understand this ability, but there is something that I'm missing it seems.

    Aegis Kleais wrote:

    But we changed it to ' / www.application ' and boom, he showed both the scope of the variables defined in the 'parent' the PRESENT and the PRESENT scope of variables in the 'child '.

    I'm surprised that it works. Do not. This is not correct, even if it does not work.

    The best way to manage the FQNs component is to use the mappings. In your example above, create a mapping to www.
