Importing - Exporting Tables, What is best to do with the following;

This is purely down to my general interest, I can do both but just wondered which is best to do?
Export a table / import table / drop table
Export table (truncated)/ import table
Any adverse effects?
To Truncate or not Truncate?
Any advice or comments gratefully received.

Hi,
If your table is going to be the same, you may go for the TRUNCATE approach.
Pros: all blocks assigned to the segment/table are not released (DROP releases space)
that will free the DB of that activity when loading data.
Cons: importing data reorganizes data, usually defragmenting space allocated...therefore you may get some empty extents (that may be used later), this is not preciselly a minus if your table is going to grow: you'll have space preallocated.

  • Hashtables: What on earth is wrong with the following code!?

    I'm loosing my mind here:
    [jdk1.4.2]
    //random code...
            Hashtable threads = new Hashtable(20);
            threads.put(portNum, ipThread); //portNum is of type int
                                            //ipThread is of type ThreadX, ThreadX extends Thread
    //other code...
            ThreadX t;
            t = (ThreadX)threads.get(packet.getPort());  //packet.getPort() returns an INTAnd the compiler returns this:
    path>javac *.java
    IPServer.java:58: cannot resolve symbol
    symbol : method put (int,ThreadX)
    location: class java.util.Hashtable
    threads.put(destinationPort, ipThread);
    ^
    IPServer.java:67: cannot resolve symbol
    symbol : method get (int)
    location: class java.util.Hashtable
    t = (ThreadX)threads.get(packet.getPort());
    ^
    2 errors
    Thanks ahead of time.

    From the JDK 1.4.2 documentation
    "This class implements a hashtable, which maps keys to values. Any non-null object can be used as a key or as a value.
    To successfully store and retrieve objects from a hashtable, the objects used as keys must implement the hashCode method and the equals method. "
    I assumed from that an int or double or any other primitive, which implements both the hashCode and equals method, would work.

  • I am moving from PC to Mac.  My PC has two internal drives and I have a 3Tb external.  What is best way to move the data from the internal drives to Mac and the best way to make the external drive read write without losing data

    Paragon even has non-destriuctive conversion utility if you do want to change drive.
    Hard to imagine using 3TB that isn't NTFS. Mac uses GPT for default partition type as well as HFS+

  • When you set up tracks what is best to pick for the input and output?

    When you set up tracks what is best to pick for the input and output? also what is the buss output? Thanks

    First part of the question I don't understand, so could you elaborate please?
    Second part: bus output is used for submixes, for example, let's say you want the same EQ to be applied to all guitars in the song, so instead of using same EQ plug-in on all guitar tracks, you feed the output from these tracks to a bus track and use the effect just once on this bus submix.

    Thank youHi Frank,
    in this example the Customer is the Java class of objects which are put into a cache and is not Coherence specific at all. This is just the return type similarly to how a (stored) function in Oracle may return a row-type containing multiple values.
    The return is a Java keyword which in a non-void method instructs the JVM to return the value of the expression following it from the method as the method return value if an expression follows it, and in a void method it simply returns from the method (no return value in this case, similarly to stored procedures).
    Sorry for my saying so, really no offense intended, but judging from your questions you might want to attend at least a beginners Java course.
    Best regards,
    Robert

  • What operating software can i upgrade to with the following specification on my macbook - 10.4.11?

    Hi,
    I hope someone can help clarify the following for me as i'm getting a bit confused by what i can and can't do..
    I have recently upgraded my macbook with new memory and ram to help improve functionality as it's quite old now.
    I have a Iphone 4s and it's apparant that i need to upgrade my operating software.
    Can someone clarify what operating software i can get with the following macbook specifiation:
    MacBook
    Model identifier: Macbook2,1
    Processor name: Intel Core 2 Duo
    Processor speed: 2 GHZ
    Number of processors: 1
    Total number of cores: 2
    L2 Cache (per processor): 4mb
    Memory: 2 Gb
    Bus Speed: 667 MHz
    Many thanks in advance
    Simon

    You can put two 2gb RAM sticks in your model 2,1 but it can only use 3,3gb. This is a hardware limitation and cannot be changed.
    http://en.wikipedia.org/wiki/3_GB_barrier
    http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-g b-memory-limitation-details.html
    OWC tests have found that there is a slight speed increase with having two 2gb sticks in rather than one 1gb and one 2gb. Your model is in the gray lines at the bottom of the graph. http://eshop.macsales.com/shop/Memory_Benchmark/Apple_MacBook/
    You can upgrade from 10.4 straight to 10.6 with no problems. Any program that runs under 10.4 should run under10.6. See this list for compatibility with 10.6: http://snowleopard.wikidot.com/  You might have to upgrade some drivers for printers, etc....
    And you will have to install Rosetta if you have any Power PC applications http://www.macobserver.com/tmo/article/snow_leopard_installing_rosetta/   I recently upgraded an older MacBook (model 1,1) straight from 10.4 to 10.6.
    Once you are at 10.6.8 Lion is still available from Apple. You will have to call Apple Customer Care 1-800-692-7753 or 1-800-676-2775. to purchase it. Then within 3 days you will get an email with a code which you can use to download Lion from the App Store.  The price is $19.99.
    Lion will require at least 2gb of RAM but really needs 4gb to run smoothly. As for third party programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
    Also Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
    Before Mac switched to Intel processors in 2006 they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.

  • Need best Architecture design for the following scenario

    Hi Experts,
    I need best architecture design for the following scenario:
    Sender: Mail
    Receiver: if sender body contain u201DApproveu201D, then call SOAP adapter, If SOAP adapter execute successfully, then  send Mail(SOAP adapter executed successfully) and SMS .  So receiver is SOAP, Mail and SMS.
    My current approach issue:
    Three message mapping:
    Mapping1: mail to SOAP
    Mapping2: mail to Mail
    Mapping3: mail to SMS
    In interface determinant>u201DSelect all three operation mappingu201D> u201Cselect order at runtimeu201D.
    Issue in current approach: For me first SOAP adapter should complete successfully, after that only my Mail and SMS operation mapping should execute:
    But problem is before success of SOAP adapter engine, Mail and SMS mapping completed or integration engine executed.
    Note: There is possible to fail the SOAP request in adapter engine.
    Kindly help me --> u201CAm I going correct way or want to change the architectureu201D?
    Thanks for advance!!
    Regards, Kumar

    What do you mean by successful execution of soap call?  Are you talking about Successful response (happy flow) from the soap call instead of application error ? Then based on the response you want to decide sending mail and sms.  How big call is your soap ?  If your soap interface is very simple I can give the other possible way.
    Sender sends the message, use mapping  to read the content and then do soap call in the mapping itself and after seeing the soap response decide about two receivers (mail and SMS).  If your soap call is very simple one, you can go for it. Otherwise I would not recommend this. The reason is you loose some visibility regards to monitoring during soap call in the mapping.
    Other option is go for CCBPM.  Here you receive the message, use send step to soap interface which is sync step. Then after seeing the response create another block with fork steps each for two senders mail and sms. If response bad then dont proceed or execute the next block. Simply use exeception or control step to jump out from the block,
