Need urgent help in Real Time scheduling algorithm implementation

I am new to Java Real Time programming. I have faced a problem which is stated below:
Declare tasks
for
if it is schedulable then run the task
otherwise it is not schedulable
for
check priority with respect to deadline.
select highest priority task
for
start higest priority task
if the task is preemtable
then switch lowest priority task to highest priority task and stop the lowest priority task
after completion higest priority task, lowest priority task complete the rest of the work.
this is actually a pseudocode for real time dynamic scheduling ( rate monotonic scheduling). can anyone please help me develop the code?

this is actually a pseudocode for real time dynamic scheduling Define "real-time" in your context. Most people who use the term don't use it correctly. If you truly mean "real-time," then you'll need real-time Java running on a real-time OS.
can anyone please help me develop the code?What specific problems are you having? If you have no clue where to start, this site is not a good resource.

    If the phone is failing to charge, then there are three possibilities -
    1) The charging cable is defective - does it work with anything else?
    2) The power source is defective - unlikely since you have tried different ones with same result.
    3) The phone has a hardware failure - which means you need to take to an Apple store or call them up for advice.

  • Need urgent help in listing out checklist from DBA prespective for BI Implementation Project

    Hello Guys,
    We are in Designing phase Data Modeling of PDW/APS Implementation Project.
    I need urgent help in making a checklist from a DBA perspective.
    Like what are things ill be needing at a time of implementation/Deployment.
    Your expert comments and help will be highly appreciated.
    Thank you,
    Anish.S
    Asandeen

    You can get good summary of checklist from this article about
    DBA checklist for data warehousing.
    Which highlights on below pointers:
    New system or old. (I.e. Up-gradation vs starting from scratch)
    Complexity of SQL Server architecture 
    SQL Server storage
    Determining SQL Server processing power
    SQL Server installation consideration 
    SQL Server configuration parameter
    SQL Server security
    SQL Server Database property
    SQL Server jobs and automation
    Protecting SQL Server data
    SQL Server health monitoring and check ups
    SQL Server ownership and control 
    based on my real time experience, I will suggest you to keep an eye on 
    Load performance (It will be useful when your database(Warehouse) will have huge amount of data)
    System availability (Check for Windows update and up time configuration) 
    Deployment methodology should be planned in advance. Development of packages and respective objects should be done systematically.
    Source control mechanism 
    Disk space and memory usage
    You might or might not have full rights on production environment, so be prepared to analyze production environment via Select statements [I guess you got my point]
    Proper implementation of Landing , Staging and Mart tables.
    Column size (this can drastically decrease your database size)
    Usage of indexes (Index are good, but at what cost?)
    I hope this will assist you in building your check list.

  • Need urgent help with HSDIO hardware timing

    Hi everyone,
    I need urgent help regarding HSDIO hardware timing. I've been working in a project which generating serial ramp using HSDIO pxie device. 
    I'm using clock rate 40MHz and generating 14 bit of boolean for each step of ramp. And I have to generate simply 256 steps ramp.
    Which means, 256 (steps) x 14 (boolean array) x 25 ns (period of 1 boolean value) = 89,6 ns.
    What I'm doing right now is with using index of FOR loop as my input data (converting the index into 14bit boolean), then write into pxie device in every iteration,
    which means, my data is getting into output in every 1ms time, right? (I'm using windows)
    And I want to be able to generate faster than that. 
    How can I prewrite my 256 steps ramp, then write them all at once into pxie device. I'm really stuck here.
    In the picture can you see how I do the write into device in every iteration of FOR Loop.
    Regards,
    Yan.

    hi, thanks for responding.
    with using example of dynamic generation with script, I can manage to generate the ramp with controllable delay (generate the whole waveform, including delay with script command, then write to the card).
    But I still have 1 question, I can test the output of the generation using oscilloscope and cant see the start delay (I'm writing delay at the start, before generating the ramp). My signal generated at 0 sec.
    How can I check this start delay? is there any good example delivered with Labview to check this generation? Somehow I cant use the "dynamic generation and acquisition" example to see my generation (cant figure out how to capture the generated signal).
    regards,
    Yan.

    Need urgent help. I have been trying to resolve this problem to no avail. I am able to preview my sprymenu on my local browsers opera, google crome, and IE but when it is uploaded, the sprymenu squashes to the left hand side.

    Please get your checkbook ready. (Only kidding.)
    Have you ever done a hard factory reset of your Airport Express base? If not, then try it. Push down the reset button with a pen, then keep it depressed as you plug AX into the wall and keep holding it down until the green light blinks 4 times and then turns amber. Then let go. Unplug your broadband modem for a couple of minutes and shut down your Mac. First restart the modem, then the Mac. Use Airport Setup Assistant to set up a new network from scratch.
    In System Prefs > Network > Show > Network Port Configurations drop n drag Airport to the top of the list and deselect all port configurations that you do not use.
    That's a start.

  • Need Urgent Help. ORA-12500 with no reason

    I need urgent help.
    I have 8.1.7.2.1 on Win2K.
    I get ORA-12500 error when trying to connect oracle instance. This problem begin to arise only when number of sessions reach a number about 200. At the same time there is no definite boundary for it. Once it happened when there were 216 session, then 196, then 206.
    There rarely (1/100) I get ORA-12514 and after again ORA-12500. Once I got ORA-12600.
    What it might be you think? It can't be a problem in listener.ora or in tnsnames.ora because it works fine if number of sessions is about 100. It tried to restart tnslistener (from lsnrctl and the service) and restarted database (but not the service). I did it different in sequences, but didn't help. What should I do? Is it a known bug?

  • Need Urgent help, I have made partition hard drive in my mac book and using OS mac

    Need Urgent help, I have made partition hard drive in my mac book and using OS mac & Window8 seperately... for couple of days it works great for both window & OS mac But nowadays, my pc gets restart automatically while using window & even I cant access to my Mac OS...........  I got some error in window (error80070003) ...>>>>> Now how can I format whole drive & recover my Mac book OS.without boot disk.

    I can't find that model. If you open System Profiler in the Utilities folder look for the Model Identifier over in the right hand display. What do you find for the model ID? If your computer supports Internet Recovery here's what to do:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer. If Mavericks is not installed, then you can reinstall it by re-downloading the Mavericks installer.
    You will need to use Boot Camp Assistant in order to create a new Windows partition, then reinstall Windows.

    Do you have a Time Machine backup or clone?  If not,
    all is lost if you have in fact deleted your OSX partition
    and you will have to do a reinstall from Recovery HD
    and install all else.

  • Need urgent help with Ifs1.1 on Solaris

    We have installed IFS 1.1 with Oracle 8.1.7 on a three tier System (two Suns). We use JWS as WebServer. When we start IFS and JWS everything seems to work fine. But after some time (irregulary) we are not able to contact the JSP-Sites via a bowser. After restarting JWS, everything works fine for some time.
    Sometimes it happens (about one times a day), that the whole JWS crashes (JWS-Admin doesn't work). So we have to restart the whole IFS.
    What can be the problem? We need urgent help, because the deadline for our project is Wednesday.
    By the way:
    Where do I have to start CTX on the IFS- or the Oracle-Side?
    null

    Yes, we tried the Oracle HTTP - Server, but we weren4t able to get it to work. We didn4t get our JSP-Files to work with it. But that is another issue. I think it4s not a problem of JWS, but IFS.
    Additionally it is strange, that we are still able to connect to the database via SqlPlus.
    IFS works fine for about 15 minutes, than it crashes, nothing works anymore. We found following errors in the IfsAgents.log:
    maybe it can help?!

  • Need urgent help!!!! (combine prompt and formula)

    Hi,
    I am using Oracle Business Intelligence 10.1.3.3.2, and creating some reports from answers. I desperately need to combine
    prompt and formula on some column.
    I need to use prompt in my formula on some column.
    Need urgent help !

    You can use the presentation variables to pass the value of the prompt into the report or any column formula.
    In the dashboard prompt you see an option called "Set Variable" where and you need to give a name to the variable.(Say Var_value)
    Now the value of the variable can be simply referenced using the syntax @{var_name}{10}. Here '10' being the defualt value which is optional you can simply reference using @{var_name} and you have the value of the prompts passed.
    Hope it works
    Thanks

  • I need urgent help to remove unwanted adware from my iMac. Help!

    I need urgent help to remove unwanted adware from my iMac. I have somehow got green underline in text ads, pop up ads that come in from the sides of the screen and ads that pop up selling similar products all over the page wherever I go. Its getting worse and I have researched and researched to no avail. I am really hestitant to download any software to remove whatever it is that is causing this problem. I have removed and reinstalled chrome. I have cleared Chrome and Safari cookies. Checked extensions, there are none to remove. I need to find an answer on how to get rid of these ads. Help please!

    You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    /Library/Application Support/VSearch
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
    Repeat with each of these lines:
    /Library/LaunchAgents/com.vsearch.agent.plist
    /Library/LaunchDaemons/com.vsearch.daemon.plist
    /Library/LaunchDaemons/com.vsearch.helper.plist
    /Library/LaunchDaemons/Jack.plist
    /Library/PrivilegedHelperTools/Jack
    /System/Library/Frameworks/VSearch.framework
    Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
    Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
    From the Safari menu bar, select
    Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including any that have the word "Spigot" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
    You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. It must be said that this failure of oversight is inexcusable and has seriously compromised the value of Gatekeeper and the Developer ID program. You cannot rely on Gatekeeper alone to protect you from harmful software.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
