Hi,
Java is an ocean. My good suggestion is to join in any training institution. If its not possible, then read Head Fist java books. These will give a good beginning to you than any other books.

    i was trying to setup adobe photoshop and i clicked setup.exe (file picture display like as a white paper) and it told me to choose application. so i dont know how to change or choose which program .. please anyone help me out on this..

    Photoshop is an application that must be purchased (not available via a download) and isn't cheap.
    You must purchase the OS X (Tiger compatible) version of Photoshop.
    Check Apple's online store under software or do a Google search.

    You aren't going to be able to delete it without the correct password.  If it's your ID, you can reset the password as explained here: http://support.apple.com/kb/HT5625.  If it isn't your ID, you will have to get the password for the person who owns the ID.  There's no way around this and no one else can help.

  • I have bought a IPhone 4 from Malaysia, my home button is not working. I want to replace the phone under warranty but all service centres mention that its country specific and I need to get it replaced only at malaysia. Can anyone guide me what to do????

    The iPhone warranty is not international and as you purchased in
    Malaysia the warranty is only valid in Malaysia
    You could try taking to an iPhone Authorised service provider
    in India but there have been many similar posts to yours
    and I am not aware  of them assisting  with an iPhone from
    outside India

    Generally, that means the phone has been jailbroken (hacked). You can try restoring it as new using iTunes. Beyond that, there's really nothing we can advise as jailbroken phones can't be supported on these forums.

    Before beginning the download, temporarily disable your antivirus, anti-adware, anti-spyware, and any other anti-whatever that is required with that swiss cheese for security OS your computer is running.

  • Can anyone guide me to ideas on basics of parallel processing in SQL

    Hi all,
    Can anyone guide me to ideas on basics of parallel processing in SQL and its usage in the the performance tuning of the query. If so what's the syntax to be followed and how to arrive at the optimized query after tuning

    My 2'c on the subject.
    Don't break your head over parallel query (PQ) processing. It should be something that is of concern to the DBA/Oracle architect - not the developer.
    Yes, it is good to be aware of how it works. But you should not write hints in your code that forces PQ processing.
    Simple example. You use hints to force a PQ of degrees 5 (meaning 5 PQ processes will be used). It works great on development. In production, 10 users are running that query round about the same time. The PQ ceiling is 20 PQ processes. The 1st 4 users each gets 5 PQs processes and the remaining 6 get none. Or another developer did the same thing, only he was very greedy and coded a PQ of degrees 20 into his SQL. So his SQL is now consuming all available PQ processes. So how did forcing PQ in your code addressed performance? It did just for a couple of users with the majority of users now facing even worse performance.
    The DBA is the one that should be tuning this. He/she can set the degree of PQ per table. Control the size of the PQ etc.
    And it does not stop there. The primary reason for PQ in Oracle is to lower the latency of I/O. Let's say Oracle needs to reads 100MB worth of data (full table scan or fast full index scan for example). It uses multi block (sequential) reads to read bigger chunks at a time. Still, a single process can only read I/O so fast - the speed of which is entirely dependant on the I/O subsystem and hardware.
    Using a second process to assist with the I/O can reduce the overall time. Instead of 1 process reading 100MB data, there are now 2 processes only having to read 50MB each.
    But as I mentioned, the actual I/O thruput is a lower level function. Let's say you start a 100 processes. Great - each only have to read 1MB worth of data. Response should be fast.
    Wrong. Those 100 processes seriously overload the I/O subsystem and throttle it so badly that the complete platform's performance is degraded severely. So instead of these 100 process speeding up I/O performance, they trash the performance of the entire platform.
    Sure, this is an extreme example. But the basic concepts are usually illustrated much better using such an example.
    So, you as developer deciding on just whether to use PQ and just how many PQ processes to use...? Wrong. It is not your decision, not your area of responsibility and usually not your area of expertise.
    Know what PQ is. Know how PQ works. But think long and hard before forcing PQ via your code (using hints) on a production platform.

  • Urgent..please anyone can help me??????

    <b>Hi all..
    please anyone can help me.for this issue....
    My Requirements is first need to MR11 tarnsaction and create zmr11 transaction and also the copy the corresponding MR11 program create Z program, which i did it.
    but now i have create a POPUP window, which contain 
    Account:           Cost Centre:
                       Internal Order:
                      Profit Centre:
    We need to copy the program for MR11 and inside it, refer to a copy of MR_ACCOUNT_ASSIGNMENT, which would contain the logic for replacing the account number picked up from configuration with that entered by the user.
    The code that needs to be added here would generate a popup, accept the account number from the user, and replace the value of KONTO with this number, which is the export parameter for the Function Module.
    At some point before the call to this FM we would need to write code to generate a pop-up, which would be populated by the user with G/L account at run-time.
    i need to modiy this internal table::::
    Call function' CKMLGRIR_BUILD_GRIR_MAINTAIN'
       tables
          lt_grirpos = t_grirpos_package
    The internal table t_grirpos_package would need to be modified at this point and populated with the values populated by the user in the pop-up screen.</b>
