Trying to understand the views for monitoring streams

Hi,
All of the columns with a measurement of elapsed_time in the following views have NUMBER as the datatype. Can someone help with me with what the actual measurement is for these field as it's definatley no seconds or milliseconds:
v$streams_capture;
v$streams_apply_reader;
v$streams_apply_coordinator;
v$streams_apply_server;
dba_queue_schedules;
When looking at V$streams_capture, column elapsed_lcr_time it is slowly incrementing when I have only replicated one insert. Why is this?
Many thanks in advance,
Warren

The views are documented in the Oracle9i release 2 REFERENCE manual. Here is the URL: http://st-doc.us.oracle.com/9.0/9202/server.920/a96536/ch3213.htm
As an example, here is the definition for ELAPSED_LCR_TIME from the manual:
ELAPSED_LCR_TIME NUMBER
Elapsed time (in hundreths of a second) creating logical change records (LCRs) since the capture process was last started

  • Trying to understand the need for typecasting

    Can someone explain why there is a need to typecast in the getObject() method? Thank you,
    public abstract class GenericTest<T extends GenericTest>
        public GenericTest()
        public void getObject()
            T objectOne = getObjectCast();
            T objectTwo = (T) objectOne.getObjectCast();  //why must I typecast here?
        public T getObjectCast()
            return ( T ) new Object();
    }

    The correct definition is (turn on your compiler warnings):
    public abstract class GenericTest<T extends GenericTest<T>> {
        public void getObject() {
            T objectOne = getObjectCast();
            T objectTwo = objectOne.getObjectCast();
        public abstract T getObjectCast();
    }

  • Trying to understand the sound system

    Here's my problem. My mic didn't work (neither the front mic nor the line-in in the rear), so after some research and trial and error I found that if I do
    modprobe soundcore
    my mic works on both the jacks
    But here's where my confusion lies. This is the output of lsmod |grep snd before probing explicitly for soundcore
    [inxs ~ ]$ lsmod |grep snd
    snd_hda_codec_analog 78696 1
    snd_hda_intel 22122 1
    snd_hda_codec 77927 2 snd_hda_codec_analog,snd_hda_intel
    snd_hwdep 6325 1 snd_hda_codec
    snd_pcm_oss 38818 0
    snd_pcm 73856 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
    snd_timer 19416 1 snd_pcm
    snd_page_alloc 7121 2 snd_hda_intel,snd_pcm
    snd_mixer_oss 15275 2 snd_pcm_oss
    snd 57786 8 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
    soundcore 6146 2 snd
    [inxs ~ ]$
    So as you can see, soundcore's already loaded, so why do I have to explicitly load it again to get the mic to work?
    Once I add soundcore to my MODULES array and reboot, the lsmod output is also the same as above.
    So my question is -- what does the explicit loading of soundcore do, that is not done by auto-loading of that module?

    Oh... since your topic is Trying to understand the sound system, that puts you (and me) inside the whole world's population... chuckle. But I thought I'd pass along a document written by probably "The" main ALSA developer that I totally stumbled across just 3 days ago.
    Go here:
    http://kernel.org/pub/linux/kernel/people/tiwai/docs/
    and download the flavor of your choice of the "HD-Audio" document, or simply view it online. It documents the deepest dive into the current ALSA snd_hda_* layers and issues that I've found to date (but still leaves me wanting).
    Why that document isn't plastered across the interwebs is beyond me. I only get 11 hits when I search for it... such are the secrets of the ALSA world I guess.

  • Am i the only one who when trying to enter the code for creative cloud activation ?

    I give up,i have been trying to activate a 3 month subscription for CS6 from Staples and every time i try the code it will not work.  I have used the chat live and spent about 3 hours already going nowhere.  I do not like talking on the phone to some help desk overseas and the only thing i think left to do is to return the junk.

    I tried all that and even took a picture of the numbers and blew them up so a blind person could read them and had 3 others read them off.  A simple way to fix the problem is get someone on Adobes staff to find a font that most people can read from whatever product the stick it to.

    Hey John,
    Not sure if it helps or not, but I know sometimes with codes like that its really hard to tell certain characters apart, O - like in Oscar versus 0 - number and number 1 versus lowercase L like in Lima.
    Might test entering it both ways if you have any suspect characters?

  • I am trying to install the driver for a Wacom Bamboo Pad. The dmg from Wacom downloadsand will opens, but when I try to install it the message "Install Wacom Tablet.pkg" can't be opened because the Identity of the developer cannot be confirmed"

    iMac late 2009 3,06GHz Intel Core Duo; 500gb hard drive, 12gb memory. OS X 10.8.5 (Mountain Lion)
    '“Install Wacom Tablet.pkg" can't be opened because the Identity of the developer cannot be confirmed.'
    I have been trying to install the driver for a Wacom Bamboo Pad. There are several driver packages listed on the website (the device is supplied ready to run with Windows devices) and I have tried tried downloading all the available drivers which apply to my set-up. Some will not open at all and I get a 'Damaged' message on my screen. Of the ones which open, I can download the .dmg and expand it but when clicked it opens as a window with multiple choice of languages and an icon which instructs you to click to open.
    If I do this some versions repeat the 'damaged' message but the later ones generate a window saying:-
    '“Install Wacom Tablet.pkg" can't be opened because the Identity of the developer cannot be confirmed.' - this is as far as I can get it to go; most frustrating!
    I understand that Apple's security updates have recently included an alteration that causes this result, and that there is supposed to be a legal (i.e. Apple sanctioned) workaround to allow files like this to be opened. If this is so, can anyone enlighten me?

    Many Thanks, Kurt.
    I knew I'd seen the solution you've provided somewhere - either in MacWorld or MacFormat - but couldn't remember the Gatekeeper bit!
    I shall save it somewhere VERY safe now in case this happens again …
    You have made an old man very happy and saved me from worrying that senile decay had suddenly set in. (I was 70 last week so you might understand the situation from that.)

  • Views for list web parts. Is there a way to allow users to change the view for a list web part without being redirected?

    Hi,
    I added a list view web part into a SharePoint 2013 page and it  is working as expected, except for one thing.
    I have enabled the option for the user to change the view for the web part. However when the user changes it, the user is redirected away from the page containing the web part, to the URL of the list itself.
    Is there a way to circumvent this issue so when the user selects a different view it updates the listing in the web part itself, rather than the user being redirected?
    Thanks in advance for the help.
    Regards,
    P.

    Hi,
    Please understand that one page can only display one view. You could find it out by observing the Address in browser when switching among different views for a list.
    If you would like to change the view of a list web part, you could go to web part propertites > Select view and configure it.
    In addition, here is a thread with similar requirement that might help:

  • I tried to update the software for my iPhone 4S. It froze, and now won't turn off, or on, or sync.  Any ideas on how to fix this?

    I tried to update the software for my iPhone 4S, 16 GB to the most recent version (8.1?).  I don't know what I was updating from, because I can't access that, but it was whatever was installed on it (I got it about a year ago, so probably 6.something). 
    It froze, and now won't turn off, or on, or sync with my macbook plus, which is what I have always sync'd it to.  (I backed it up and sync'd it right before I tried to update the software.)
    Since it originally froze almost 3 hours ago, it shows a white screen with the apple on it and a line underneath.  When I try to sync with my laptop, it says it needs me to enter a passcode on the phone, which I can't enter because the screen is frozen.  So I'm unable to access the iPhone portion of iTunes.
    I have tried to turn it off, with no luck.  I have tried rebooting my laptop and syncing, but I still get the same result.
    Does anyone know how to fix this?
    I really wanted to wait to update the software, but I was having internet connectivity issues for the past 3 weeks, and Sprint suggested updating the phone's software.
    Thanks in advance for your help!

    Hi NWL1,
    Thanks for the question. If I understand correctly, the iPhone won't update and is stuck. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

  • [SOLVED] Trying to understand the "size on disk" concept

    Hi all,
    I was trying to understand the difference between "size" and "size on disk".
    A google search gave plenty of results and I thought I got a clear idea about
    it.. All data is stored in small chunks of a fixed size depending on the
    filesystem and the last chunk is going to have some wasted space which
    will *have* to be allocated.. Thus the extra space on disk.
    However I'm still confused.. When I look at my home folder, the size on disk
    is more than 320 GB, where as my partition is actually less than 80 GB, so
    I guess I'm missing something.. Could somebody explain to me what does
    320 GB of 'size on disk' means?
    Thanks a lot in advance..

    Hi all,
    Thank you for your replies.. My file manager is indeed pcman fm and
    indeed it seems to be an issue.. In b4data's link the last post reads:
    B-Con wrote:
    FWIW, I found the problem. (This bug is still persistent in v0.9.9.)
    My (new) PCManFM bug report is here: http://sourceforge.net/tracker/index.ph … tid=801864
    I submitted a potential patch here: http://sourceforge.net/tracker/?func=de … tid=801866
    Bottom line is that the file's block size and block count data from the file's inode wasn't being interpreted and used properly. The bug is in PCManFM, not any dependent libraries. Details are in the bug report.
    Since PCManFM is highly used by the Arch community, I figured I should post an update here so that there's some record of it in our community. Hopefully this gets addressed by the developer(s) relatively soon. :-)
    I guess that pretty much explains things.. And I think I did understand the 'size on disk' concept
    anyway
    Thanks again!

    You've probably already seen these, but here are a couple of links that may help.
    http://help.adobe.com/en_US/FlashPlatform//reference/actionscript/3/operators.html#array_a ccess
    http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/Array.html
    What's basically happening is that the "for" loop goes through each item in the array.  Don't be confused by the fact that two of the items in the array are Strings and one is an Integer - variable i being a String has nothing to do with the data type of the elements in the array.
    The following code:
    private function createLabels():void
         var myArray:Array = ['one', 'two', 3];
         for(var i:String in myArray)
              trace("i = " + i);
              trace(myArray[i]);
    gives the following results:
    i = 0
    one
    i = 1
    two
    i = 2
    3
    From that we can see that the "for" loop is assigning the index number of each array element, not the actual array element ('one', 'two', or 3) to the variable i.  So calling myArray[i] is the same as calling myArray[0] the first time through the loop.  This type of "for" loop is just a shorter way of doing the following, which produces exactly the same results:
    private function createLabels():void
         var myArray:Array = ['one', 'two', 3];
         for(var i:int = 0; n < myArray.length; i++)
              trace("i = " + i);
              trace(myArray[i]);
    Hope that helps.
    Cheers!

  • Trying to understand the basic concept of object oriented programming.

    I am trying to understand the basic concept of object oriented programming.
    Object - a region of storage that define is defined by both state/behavior.
    ( An object is the actual thing that behavior affects.)
    State - Represented by a set of variables and the values they contain.
    (Is the location or movement or action that is the goal that the behavior is trying to accomplish.)
    Variables- (What does this mean?)
    Value - (What does this mean?)
    Behavior - Represented by a set of methods and the logic they implement.
    ( A set of methods that is built up to tell's the how object to change it's state. )
    Methods - A procedure that is executed when an object receives a message.
    ( A very basic comand.For example the method tells the object to move up, another method tells the method to go left. Thus making the object move up/left that combination is the behavior.)
    Class - A template from which the objects are created.
    ( I am very confused on what classes are.)
    - The definitions of the words I obtained from the "Osborne Teach Yourself Java". The () statements are how I interperate the Mechanisms (I do not know if Thats what you call them.) interact with each other. I understand my interpretation may be horribly wrong. I will incredibly appreciate all the support I may get from you.
    Thank you

    Object oriented programming is a replacement for the older idea of procedural programming (you can research procedural programming in google). As I understand it, in procedural programming, you have a step by step set of function calls to accomplish some task. Each function receives a data structure, manipulates it, and passes it to the next function. The problem with this is that each function preforms some action for the overall task and can't easily be reused by some other task. Its also harder to read the flow of what is happening with raw data structures flying all over the place.
    In object oriented programming, an object calls a function of another object and receives back, not a data structure, but another object. Objects contain a data structure that can only be accessed by its functions. An object is not so much a sub component of a bigger task, as it is a service that any other task can use for any purpose. Also, when you pass an object to the caller, the caller can ask questions about the data structure via its functions. The developer doesnt have to know what the previous function did to the data by reading up on any documentation, or having to reverse engineer the code.
    I suggest the best way of learning this is to code something like a library object.
    A library object contains a collection of book objects
    A book object contains a collection of chapter objects
    A chapter object contains a collection of paragraph objects
    A paragraph object contains a collection of sentence objects
    A sentence object contains a collection of word objects.
    Add functions to each object to provide a service
    Example: A library object should have a:
    public void addBook(Book book)
    public Book getBook(String title)
    public boolean isBookInLibrary(String title)
    The key is to add functions to provide a service to anyone who uses your object(s)
    For example, what functions (service) should a paragraph object provide?
    It shouldn't provide a function that tells how many words there are in a sentence. That function belongs to a sentence object.
    Lets say you want to add a new chapter to a book. The task is easy to read
    if you write your objects well:
    Sentence sentence1=new Sentence("It was a dark and stormy night");
    Sentence sentence2=new Sentence("Suddenly, a shot ran out");
    Paragraph paragraph=new Paragraph();
    paragraph.addSentence(sentence1);
    paragraph.addSentence(sentence2);
    Paragraphs paragraphs=new Paragraphs();
    paragraphs.addParagraph(paragraph);
    Library library= new Library();
    library.getBook("My Novel").addChapter("Chapter 1",paragraphs).
    Now, lets say you want to have a word count for the entire book.
    The book should ask each chapter how many words it contains.
    Each chapter should ask its paragraphs, each paragraph should ask
    its sentences. The total of words should ripple up and be tallied at each
    stage until it reaches the book. The book can then report the total.
    Only the sentence object actually counts words. The other objects just tallies the counts.
    Now, where would you assign a librarian? What object(s) and functions would you provide?
    If written well, the project is easily extensible.

  • Trying to understand the Serialization interface

    Im trying to understand the Serialization of objects?
    As an example, I create a Library class that implements Serializable, that stores a collection of Book objects
    If I am only looking at saving a Library object to file, does the Book class require Serialization also or just the Library?
    I have read the API on serialization, no answer there, if it is it's not easy to understand or read into the API...

    There are some really important things to know about when doing serialization. For example one important thing to know about that not is mentioned here is that your serializable classes must define its own private static final long serialVersionUID because if you not do that will you not be able to deserialize (read in) the data you have saved later if you change anything in your serializable class. It is a bit tricky to manage files to which you have serialized different versions of your class, that is versions where you have added more serializable members to the class after you have serialized files. Well, it is not a problem if you don´t care if you have to type in all your saved data again every time you change anything instead of deserialize it (read it) from your file of course :)
    Situations like this may be handled if you define your own (private) writeObject(ObjectOutputStream) and your own readObject(ObjectInputStream) methods in your serializable class but there is a better a lot smarter way to handle this. Use of a serialization proxy! how to use that is described in the excellent book Effective Java 2nd ed. With a serialzation proxy for every serializable version of your class (where a version corresponds to a version of your class with differences in its number of serializable members) may your class deserialize data written from elder versions of your class also. Actually is it first since I read the last chapter of Effective Java that I think I have myself begin to understand serialization well enough and I recommend you to do the same to learn how to use serialization in practice.

  • Trying to change the labels for some UI elements

    hi,
    Problem:  I am trying to change the labels for some UI elements and transport the views from one server to another server.
    the lables show changed in the source server but the changes dont reflect in the destination server
    Kidly help me to slove this problem

    Hi Sharad
    The process is as explained:
    1.     Firstly, go to the respective view, and to the Label and then delete the Label Text as   
                    mentioned in the attribute u2018TEXTu2019 of the Label in the view.
    2.     Next, Activate the View, if it asks for a change request, please assign it to a new TR.
    3.     Finally give the Label text again and then Save it and activate it.
    4.     Further transport the request to ECP and find the difference.
    This especially happens when we frequently change the WD Component and embedd it entirely in the Transport.
    I hope this information would be of a great help to all of us.
    Ponts if helpful.
    Regards
