  • How Can implement the audit function using toplink?

    My system must record all the modification, how can I use toplink to implement it.
    I know when toplink modify some object, the toplink will check how many attribute
    have been modified, and then update it to database, Can I implement the record when
    the toplink check modification?
    PS: I dont want to use database trigger.
    Thank first!!

    This thread has been inactive for a while, so perhaps I'm missing something. I am attempting to create audit events on domain objects using a TopLink 10.1.3 DescriptorEventAdapter.
    These audit events mutate or create a snapshot collection on the domain object. Based on what I understand from the above thread, do I still need to create another UoW to commit these in my preInsert()/preCreate() handler methods?
    Is there a way to get in the game before the IDs are assigned to the objects and the change set is computed?
    I certainly don't claim to fully understand the historical client session docs. However, one of our requirements is to show object-attribute-level deltas (list chronologically, grouped by transaction, the attributes that have changed, who changed them, etc. with their before and after values). So my first-blush reaction is that it's easier to utilize the change set to create a collection of transactionally-grouped audit objects on the domain.
    Thanks much,

  • Can we call the Human Task operations and the Rule Designer, etc. from outs

    Hi,
    I just had one of my customers ask me -
    Can we call the Human Task operations and the Rule Designer, etc. from outside the SOA Suite ??
    Since these are independent applications, and that they are based on Service Oriented Architecture, I should be able to call these services from outside Oracle SOA Suite (SCA) for reuse.
    In case you have any idea about the possibilities, could you share some real world examples / URLs please ?
    Thanks & Regards

    Hi Vaibhav,
    Yes, you are right. We are using Oracle SOA suite 11g.
    My question is, can these Web Services be directly accessed from, say a .NET application without using BPEL PM, or is using BPEL a must to invoke these services in Human Task operations, Rule Designer, etc ?
    Regards

  • I accidentally deleted iPhoto on my mac and it says the the app was downloaded with a different apple id and now i can't get the app back without paying $14.99

    i accidentally deleted iPhoto on my mac and it says the the app was downloaded with a different apple id and now i can't get the app back without paying $14.99

    Did you install it yourself are somebody else for you?
    If you installed them yourself, but do not remember which AppleID you used, try all AppleIDs you might have used in turn.
    If somene else set up your Mac for you, ask the person to reinstall it. If you bought the mac second hand, the previous owner needs to contact Apple to transfer the iLife apps. If that is not possible, delete the apps that you cannot update and buy them using your AppleID.

  • Can I open the Mail app without configuration an email address?

    I'm trying to open a .eml file, which seems possible in the Mail app.  However, I can't open the Mail app without configuration an email account.  I don't have an email account to configure; just want to open the file.  Or, let's suppose, I just wanted to browse the interface?  How to avoid the account setup part?

    Just enter anything short & plausible in as few fields as you can get away with : '[email protected]' works here, you'll get a brief 'not responding' or such at each stage, but it does allow you to use Mail.

  • Actually i have a apple account without credit card in usa i have just got a itunes gift card from an application so can i redeeme the gift card without credit card????

    actually i have a apple account without credit card in usa i have just got a itunes gift card from an application so can i redeeme the gift card without credit card????

    Yes you can redeem the card if it is a U.S. gift card, you have a U.S. based iTunes account and if you are using the U.S. stores on the iPad.
    On the iPad - Swipe to the bottom of the screen in the App Store or in iTunes and tap on Redeem. If you are using iTunes on your computer, you should see Redeem under Quick Links (i think that is where you will see it) after you sign into the store.

  • Can I rewrite the following query without using Row_number() function ??!!

    Hello every one, can I rewrite the following query without using the 'ROW_NUMBER() OVER ' part.
    The query is supposed to pull out the records whose CODE is not NULL and has most
    recent date for UPDATE_DATE . The reason I wanted to do this is, When I embed this query
    in between many other queries along with JOINs, My oracle server is unable to execute. So, I thought
    its better to supplant 'ROW_NUMBER() OVER ' logic with something else and try it. .
    SELECT a.* FROM
    (SELECT b.*, ROW_NUMBER() OVER (PARTITION BY b.PIDM
    ORDER BY b.UPDATE_DATE DESC) AS Rno
    FROM
    SELECT *
    FROM SHYNCRO WHERE CODE IS NOT NULL
    )b
    )a
    WHERE a.Rno = 1

    Hi,
    You didn't write over 150 lines of code and then start testing it, did you?
    Don't.
    Take baby steps. Write as little as pssiblem test that. Debug and test again until you have something that does exactly what you want it to do.
    When you have somehting that works perfectly, take one baby step. Add a tiny amount of code, maybe 1 or 2 lines more, and test again.
    When you do get an error, or wrong results, you'll have a much better idea of where the problem is. also, you won't be building code on a flimsy foundation.
    If you need help, post the last working version and the new version with the error. Explain what you're trying to do in the new version.
    The error message indicates line 133. It looks like line 133 of your code is blank. Does your front end allow completely blank lines in the middle of a query? SQL*Plus doesn't by default; you have to say
    SET  SQLBLANKLINES  ONto have a completely blank line in SQL*Plus. (However, lines containing nothing but at commnet are always allowed.)
    You may have noticed that this site normally doesn't display multiple spaces in a row.
    Whenever you post formatted text (such as indented code) on this site, type these 6 characters:
    \(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
    The 4 people who posted small code fragments for you to read all did this.  It would be so much easier for people to read your humongeous query if it were formatted.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

  • Can u write the following query without using group by clause

    select sp.sid, p.pid, p.name from product p, supp_prod sp
    where sp.pid= p.pid and
    sp.sid = ( select sid from supp_prod group by sid
    having count(*) =(select count(*) from product));
    thru this, we retrieving all the products delivered by the supplier.
    Can you write the following query without using the group by clause

      select sp.sid, p.pid, p.name
        from product p, supp_prod sp
       where sp.pid= p.pid the above query will still retrieve all the products supplied by the supplier. sub-query is not necessary.
    maybe if you can post some sample data and output will help us understand what you want to achieve.

  • How can I implement the connection pool in my java stored procedure

    my java stored procedures (in database 'B') have to connect to another oracle database ,let's say 'A'. And how can I implement the behavior like the so-called connection pool in my java stored procedure in 'B', as below.
    1. database B, has 2 java stored procedures sp1 and sp2
    2. both sp1 and sp2 connects to databse 'A'
    whatever I call the sp1 and sp2 and the database 'A' always only one connected session from sp1 and sp2 in database 'B'.
    THANKS A LOTS...

    my problem is I have a lots of java stored procedures need to cnnect to the remote oracle db, and I hope the remote db can only have a connected session from my java stored procedures in my local db. I try as below
    class sp{
    static Connection conn=null; //the remote db connection,
    public static void sp1(){...}//procedure 1, using conn
    public static void sp2(){...}//procedure 2, using conn,too
    I can 'see' the 'conn' variable if I invoke the sp1() and sp2() from the same client application(maybe sqlplus). But if I invoke the sp1() from client 'A' and invoke sp2() from client 'B' then the sp1() and sp2() can not see the 'conn' variable for each other. I think it's because the two clients cause oracle to create two instances of the class 'sp' and the sp1() and sp2() located in different instance seperately. Thus the sp1() and sp2() can not see 'conn' for each other. They can only see its own 'conn'.
    To connect to the remote db from the java stored procedure is easy but is it possible to connect to the remote db via database link from the java stored procedure at my local db ? If so, then I also archive my goal .
    BTW , thanks a lots...

    Thanks.  I do not have the experience on burning discs from iMovie for the movie after editing (ie for video discs players).  It seems that i cannot find the relevant command in the tool bar for this purpsoe.  Would you please show me the way?
    The command is gone because iDVD has been discontinued by Apple. After Apple discontinued iDVD they removed the iDVD burning link from iMovie. I still use iDVD sometimes, only because I have an old copy.

    I don't know what RF means. When I have used HandBrake, I've used presets that apply to what I want to do, so I don't know the meaning of each individual setting. However, it appears that many of them are listed in the HandBrake User's Guide that is linked from the Help menu in the program:

    Photoshop is not amateur-level software, and although it can edit a video, it cannot burn a DVD. Unfortunately, because I still use iMovie, I haven't tried anything else. You might want to read the reviews of various DVD-burning applications in the Mac App Store.
