What is the difference between Real-Time (RR) and Time-Sharing (TT)?

Hi Guys,
I am trying to distinguish between LMS process priorities of Real-Time Vs Time sharing and was not able to find any good document explaining me the difference between them. May be one of you Gurus can explain the difference between TT and RR? Any metalink doc id or any url on this issue will be appreciated.

Hi, Time Sharing scheduling is based on credits that are allocated to the process while creation and as long as process keep consuming the OS resources (CPU etc), its priority keeps on changing dynamically (Because process has lost credits) where as processes with Real Time Scheduling are given priority over other processes configured with Time Sharing (even kernel resources).
In simple terms, if LMS is configured with Time Sharing scheduling on a very busy Oracle RAC system, LMS process may contend for the CPU resources, which may cause performance bottleneck in cluster environment.
In Oracle Real Applicaiton Cluster, various organizations has gained performance benefits of setting few Oracle processes such as LMS with Real Time scheduling.

  • What is the difference between WTR1 stock price and Price,some time both are zero?

    what is the difference between WTR1 stock price and Price,some time both are zero?
    please advice

    Hi,
    Are you referring these two field in WTR1 table? If yes,
    (Figure 1 There is no price defined and received with zero price)
    1. Based on price list, this info price will be updated. If there is no price, this field is zero
    2. If you receive any item without price (for GRPO with zero price), then field is zero
    3. If you receive item with price, based on quantity, the moving average price will be updates at item cost.
    Thanks & Regards,

  • What is the difference between Wine, Wineskin, Winery and Wine Bottler, and how do I get Wine to *ACTUALLY* work in Mountain Lion?

    Ok, so this is my first post here and I am admittedly terrible at forums. Someone might say, "This was addressed in the ___________ thread by __________! Go read it!" --- that may be so but I've spent enough hours trying to google this problem into submission to no avail based on what is apparently working for others, so I would like a chance to get specific answers to specific questions that aren't from Mar 2011, etc.
    So first of all, I'm confused by all the various Wine programs/apps/whatevers. I've seen Wine, Wineskin, Winery, Wine Bottler, and at this point I wouldn't be surprised if there are even more than that. What's the difference between all of these and how do they work with one another? What do I actually need to get windows programs working?
    All of my google searches have led me to people giving out fish, but no one giving out fishing lessons. I'm not a pro at mac and windows and all that, but I'm a fairly bright individual who gets VERY frustrated, very quickly, when I don't understand the why and how of something I'm attempting.
    I've also found "answers" where the person attempting to help starts off helpful enough, but degrades into the most archaic of techno-babble after about 5-6 sentences. On the other hand, I've watched tutorials on youtube where the poster decides to skip (apparently crucial) sections of the tutorial, and mutters such gems as: "... you might wanna have to run Wine first before you can do anything, cuz I think it has to configure it and set up a bunch of stuff" 
    O.o
    A happy medium between techno-babble and the most basic of explanations would be ideal for me, and I'd imagine for others as well.
    Here is a summarized history of my relationship with Wine:
    Diablo II - I downloaded this awesome thing which ended up being... uh... I guess Diablo II in a Wineskin "wrapper". I'm not sure, all I know is that it's a D2 icon, and if I go to 'show package contents', it's got C drive, Program Files, et cetera inside of it. I double click it, it launches D2, and it works like a dream. <3
    'Vanilla Install' - That's what I heard someone call it. It was the command/terminal style install using xquartz and xcode found at http://www.davidbaumgold.com/tutorials/wine-mac/. I followed every instruction to the letter, and got all the way to '$ sudo port install wine', at which point it started going smoothly, free from the possible error he described regarding the installation of xcode, and then just failed after I left the room to use the restroom and came back. Please don't ask me to repeat what the error was, because honestly, after reading more things on the interwebs, I'm confused as to why it's even necessary to go through all of that, so I'd rather not try that route again anyways, rendering the error message quite possibly irrelevant.
    Wine + Wine Bottler - So I decided to try to seek out an easier method, as I know that one must exist that doesn't involve command lines. I found a video tutorial at http://www.youtube.com/watch?v=m0BBkISOcEA, and oh man would it be great if that method had actually worked. Again, I followed all instructions provided to procure my free fish, and at the point in the video where he declares that "xquarts or x11 will open" - it doesn't open. Nothing opens. I was trying to install Star Sonata, btw.
    So here I am, thoroughly worn out, frustrated at all the random places Wine is installed on my mac now, and just want someone to explain it all, from top down, without getting toooooooo technical on me. I know that might be asking a lot...

    ## I know that the poster has already found a solution, but the following is a possible answer for others that have similar issues.
    For Winebottler, just go to their website and download it. Run the program. Choose .wine as your prefix (best choice) or whatever suits you best. You'll need a functional X11. If you can't use the one that comes with your mac, download the latest one from the website.
    If your issue is one with Winebottler's Wine not running correctly due to X11, then you have a pretty ugly problem, although a simple upgrade is the best solution (Upgrade XQuartz.app).
    http://www.davidbaumgold.com/tutorials/wine-mac/#part-1
    The above website is the easiest way to get REAL wine on your computer. First of all, Wineskin WInery, etc. are NOT WINE. They are 3rd party apps that may use Wine or may have originally part of Wine, but they are no longer up to date with Wine. WineBottler is currently up to date with the stable releases of Wine (but not the maintenence releases).
    For the website tutorial and to run Wine on your mac without using a thrid party app, you will need to know a few things.
    First, you will need to know basic control of the command line. That means, sudo (you must know the administrator password to your computer), and the forms of cd (change directory).
    Second, you will need Xcode. Download 4.2 (stable) or whatever other versions you want, but beware: It is over 1 GB, and you will need time for it to work.
    Third, you will need to get MacPorts and configure it. The tutorial should have this data.
    When you download wine (use sudo port install wine-devel for the latest development release of wine), it will first download a lot of dependencies. This will take a while. After that, it will download wine itself.
    After obtaining wine, to run a program, open the terminal.app window.
    cd desktop/XYZ/ZYZ\ WRQ
    The above will first enter the desktop, then folder XYZ, then folder ZYZ WRQ. From here,
    wine th11e.exe
    Or whatever executable you are trying to open. (Using Subterranean Animism as my example).
    It should, in theory, run the program. Watch the terminal for errors. If there is an X11 problem, then it's not wine acting up. If the app crashes or has other issues, check the Wine Application Database to see if your app is compatible with wine.
    If you have any further questions or other things, feel free to reply; I may or may not get back to you, but there's a good chance that someone will come in eventually. Otherwise, the Wine Wiki should have some information.

  • What is the difference between MacBook pro 2011 and 2012

    What is the difference between MacBook pro 2011 and 2012

    understanding that at the time of the question, there has not been any Macbook Pro 2012, now it is later and there is.
    The difference is:
    -CPU being used (2011 models: Sandy Bridge, 2012 models: Ivy Bridge)
    -Graphics (2011: intel 3000 + on 15"/17" ATI, 2012: intel 4000 + on 5"/17" nvidia Geforce 650M)
    -USB (2011: USB2.0 only, 2012: USB3.0)
    -Bluetooth (2011. 2.1 + EDR, 2012: 4.0)
    Ivy Bridge CPUs are smaller and are a little bit more energy-efficient.
    Other than that, currently the devices are not much different in respect to performance (Apple's graphics driver performance is known to increase during upgrades, though, so the performance gap may widen up)

  • What is the difference between lock mode E and X.

    what is the difference between lock mode E and X.

    Hi
    The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table
    Lock modes:
    S (Shared):
        Several users (transactions) can access locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock set on an object that already has a shared lock will be rejected.
    E (Exclusive).
    An exclusive lock protects the locked object against all types of locks from other transactions. Only the same lock owner can reset the lock (accumulate).
    X (eXclusive non-cumulative):
      Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. Each further lock request will be rejected.
    O (Optimistic):
      Optimistic locks initially behave like shared locks and can be converted into exclusive locks.
    If it is helpful rewards points.

  • What is the difference between saving to "Documents" and "Macintosh HD" and when should you use each one?*

    What is the difference between saving to "Documents" and "Macintosh HD" and when should you use each one?

    When you save to the folder with the little house icon, the file is placed at
    /Users/your_user_name/
    You would really have to go out of my way to save at:
    (the shortcut for the Boot Drive, regardless of its name).
    I am not sure how you decided that Time Machine is not saving your files. The default is for Time Machine to do incremental Backups of everything on all attached drives, except for certain temporary information in Cache files. If you have four Users, Time Machine will back them all up.
    Looking at the raw Time Machine backups will tell you very little, because it does lots of its work with Hard Links, and because it does incremental backups, so only files that changed since the last Backup are saved at thet cycle. The way to determine whether Time Machine is saving things is to display the window you care about in the Finder, then invoke the "Star wars"/ "Back, back, back in time" Interface.

  • What is the difference between Recon. Account and Alternative Recon. Accoun

    hi
    any body please tell me . What is the difference between Recon. Account and Alternative Recon. Account.

    Hello sairama,
    Reconciliation account- For each subledger account , you must keep at least one reconciliation account in the general ledger. When you post to an account in the subledger, the system automatically posts to the corresponding reconciliation account. The "Receivables from goods and services" account is an example of a reconciliation account for customers. Enter Customer in the Reconciliation account for account type field. Enter a Vendor in this field for a vendor reconciliation account. Using the reconciliation account procedure, it is possible to create a balance sheet and a profit and loss statement at any time, since the amounts posted to subledger accounts are also posted automatically in the general ledger.
    During regular reconciliation, you check whether the balance of the reconciliation account matches the balance of the corresponding subledger account.
    You define reconciliation accounts by specifying in the G/L account master record the account type (such as fixed assets, vendor or customer) for which the account is to be used. In this way, the account can only be assigned to accounts in the corresponding subledger. You set the assignment of the subledger account to a reconciliation account in the master record of the subledger account. You cannot post to reconciliation accounts manually .
    ============================================================
    Alternative Reconciliation account- Special G/L transactions are identified by a special G/L indicator. The system uses the specifications (posting key and special G/L indicator) to determine the alternative reconciliation account.
    When you post a special G/L transaction, the system does not post to the normal reconciliation accounts but instead automatically to alternative accounts, that is, special G/L accounts. Consequently, you do not transfer the balances of these accounts either. Instead, the system posts to the appropriate accounts automatically when the open items are transferred.
    Hope I had been able to help you. Please assign points.

  • What is the difference between on new focus and do prepare out put methods

    Hi,
    what is the difference between on new focus and do prepare out put methods.

    Hi Divya,
    DO_PREPARE_OUTPUT method is triggered each time the view is prepared after each event. Normally we redefine this method in order default the initial values based upon the parameter iv_first_time = 'X'. There can be certain other scenarios like putting data validations where this method can be helpful.
    For details on ON_NEW_FOCUS, refer to this [thread|on_new_focus event;

  • What are the differences between a trial version and a licensed copy of RoboHelp?

    What are the differences between a trial version and a licensed copy of RoboHelp? How is original Robohelp software useful compared to the evaluation version (freely downloaded software)
    Thanks.

    Welcome to the forum.
    The only difference should be that the trial is limited to 30 days use. All functionality works and nothing is watermarked Trial or suchlike.
    The trial of the standalone version allows you to link to FrameMaker documents. It should not and that feature will be disabled if you proceed with the full version. Other than the time limitation, that is the only difference.

  • What is the differences between T=0 protocol and T=1 protocol?..

    Hi friends..
    Sorry, i want to know what is the differences between T=0 protocol and T=1 protocol?..
    Which one is the best, Java Card that support for T=0 protocol and Java Card that support for T=1 protocol?..
    Thanks in advance..

    Sebastien_Lorquet wrote:
    Such protocols have NOTHING TO DO with javacard. They have been existing for YEARS before javacard was invented.
    It's just a mean to exchange data with any card. It happens to be a standard, so javacards among others use it to communicate with the host.
    the Javacard spec by itself does not know anything about how the APDUs are exchanged . It can be T=0, T=1, T=14, RS-232, GPIB, USB, ISO14443, Felica, Ethernet, Firewire, a satellite link, a deep space link, or anything you want. The comm part is the responsibility of the card operating system, which is out of scope for the javacard machine that lies onto it.
    Just because you have a convenience method in the APDU class does not mean this is real. It's up to the card / os manufacturer to define these things, it's reasonable to think they are accurate, but I can create a javacard that claims to be contactless and still will use T=0. That's arbitrary.This is not exactly true. For APDU response chaining to work on some T=0 cards (when using smartcardio that handles response chaining for the developer) we had to use some special tricks. It can also be handy to only allow certain actions on the contact interface (such as admin actions etc) to prevent unauthorised access. The [PLAID Applet|https://www.govdex.gov.au/confluence/display/PLAID/Home;jsessionid=9B9EC664A01EC13B098DDF4EE5760A0A] (developed by the Australian fegral government agency Centerlink) only allows the card to be initiliased through the contact interface.
    - T=0 requires a GET RESPONSE additional exchange only for case 4 commands or when the command provides more bytes than requested for an outgoing command. It can also require more than two exchanges if the terminal requests the outgoing data per-block.Don't forget case 2. The GET RESPONSE is at TAPDU layer and is handled internally by smartcardio/PCSC etc and is also handled by the smartcard OS.
    Leonardo, if you want to know the differences between the two, I recommend reading ISO7816-3.
    Cheers,

    What is the difference  between a mac-book and an I-pad?

    The Macbook is a computer (running Mac OS X), an iPad is a tablet (running iOS). What are thinking of using it for ? The Mac is more powerful than iPad, so if you need processing power then that will be better suited for your needs. If you will mainly be using it for media (films, music), internet browsing, emails, ebooks, then an iPad would be sufficient.

    HI,
    What is the difference between Component,Server,Tool and Software?
    SHABEER

    Hi
    Every individual part that constitutes in making an SAP System is called a COMPONENT.e.g DB instance, Java CI, ABAP CI etc
    SERVER is the actual composition of different components of SAP.e.g. a database alongwith can instance would constitue an application server.
    TOOLS are the products from different organisations (SAP or Non SAP) that can be used for different functionalities like keeping a check on jobs, monitoring of the system , e.g Tivoli
    SOFTWARES are a kind of tool that help you to bring up results from the system in a user acceptable format. These are utilities that act as interfaces between the user and the system.

    Hallow all,
    Can anybody please explain, What is the Difference between Condition type PB00 and PBXX in Materials Management Pricing?
    And also please explain control or Application of both on Price determination ??
    Thanks in Advance !!!!!

    Hi,
    PB00 condition type is used for automatic pricing in PO
    PBXX condition type is used for manual pricing in PO
    In Pricing  access sequence  play a vital role . If you need pricing automatic in the PO, you have use of Access Sequences and Schema Group of Vendor.You can see the difference in both standard condition type PB00 and PBXX, where as PB00 is assigned to Access sequence(0002)but in case of PBXX no access sequense assigned.
