Run more than one application at once?

I�m trying to run two projects at once using the play button in JSE. The two projects workes together so I want to test them simultaniously.
How can I start the two server instancies on different ports?

I�m trying to run two projects at once using the play
button in JSE. The two projects workes together so I
want to test them simultaniously. Don't think that's possible. If it's for testing purposes - just make one of the projects sleep for a second while you run the other. If you are working with a client/server thing it might be good idea whatsoever to make the server wait for the client connections..
How can I start the two server instancies on
different ports?Indeed first you have to create a second instance and register it in the IDE. The you will be able to start them both, just like mik_k pointed out.

  • IMac (2008) OS10.6.8 - Main menu freezes when running more than one application at a time.  Apple and 3rd party applications - all freeze the main menu.  Safe mode seems to work OK. Tried repairing permissions - didn't work.

    For the past 60 days I've experienced Main Menu freeze when running more than one application at a time.  iPhoto, Preview, Text Edit, Epson Scan, Firefox and Thunderbird are the apps I use almost daily.  No matter what I do, when more than one is running they will freeze the Main Menu (top of the screen).  I've tried booting is Safe Mode and I don't seem to have a problem.  I've tried several suggestions from repairing permission (DiskUtility) to eliminating specifis login items.  Nothing works. I've posted this issue on the Apple forum several times and no one else has experienced this problem.  I hesitate to take my iMac to the Apple Store or a private Apple repair service until I've exhausted all of my options.  Do I have any more options?    

    Question:  Everytime an app crashes I have the option to report it to Apple - which I usually do.  But I've NEVER reported a Main Menu freeze because it never asks me to
    There's really no need to submit to Apple, it's just a round file cabinet on the other end, especially with 10.6 or earlier.
    This sure sounds like a resource problem...

    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
    How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    In the Memory tab, are there a lot of Pageouts?

  • My 2009 iMac freezes and won't run more than one application at a time - how can I fix this?

    Help! My iMac has been getting worse regarding freezing, especially when trying to open iPhoto. It will load slowly, and then I get the pinwheel of death for ever, until I shutdown and try over again. It usually takes several tries, and usually overnight. How can I resolve this issue?

    First, back up all data immediately, as your boot drive might be failing.
    Step 1
    This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Triple-click anywhere in the line below on this page to select it:
    syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|timed? ?o' | tail | open -ef
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
    Step 2
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Reset the System Management Controller.
    Run Software Update. If there's a firmware update, install it.
    If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
    If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
    Step 3
    When you notice the problem, launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the View menu or the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
    Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
    Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
    Step 4
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • Can I run more than one app at once, I.e.: keynote and a point of sale app?

    See above..

    If they support multi-tasking then yes (you can't have two apps side-by-side on the screen if that is what you want). Just double-press the home button to bring up the taskbar which displays open and recently used apps and tap the one that you want to switch into - you will need to make sure that both the apps that you want to switch between are open/recently used first, otherwise they won't appear on the taskbar.
    Also not all apps support multi-tasking (they have to be coded to support it), those that don't will just appear on the taskbar due to having been recently used - so if you re-open them from there they may not resume from where you last were.

  • Seeing more than one application at once using extended desktop display

    Hi, I have just bought a new dvi external monitor and connected it to my MBP. In extended mode I can't seem have one app open on the external screen and another app on the mbp screen - as soon as I open a new app, the existing one disappears even if I've already dragged it accross to the external monitor. Not sure if it is something to do with spaces but it's bugging me. Any ideas gratefully received. Thanks

    Depends on the apps, whether they are hidden, etc. You should be able to do what you are trying to do - I have Safari open on an external display, Word open on the internal display, for example.

    You must have a class (code) to start each "application". To keep the environments clean from each other you can use a class loader.

  • Cannot run more than one instance of a remote app in remote desktop services Server 2012

    All,
    I installed "Remote Desktop Services (RDS) Quick Start Deployment for RemoteApp, Windows Server 2012 Style" using the instructions here http://blogs.technet.com/b/yungchou/archive/2013/02/07/remote-desktop-services-rds-quick-start-deployment-for-remoteapp-windows-server-2012-style.aspx
    I need to set up an image viewing program (Olyvia) to allow students using Macs and iPads access to this windows only application in order for them to get their work done.  We may have 12 or more students accessing and trying to run the Olyvia application
    at any one time.
    All works good, except that I cannot run the Olyvia application (setup as a remoteapp program) more than one instance at a time.  That is, when I start up "olyvia" on a Mac, it works great.  If I leave it up and running, and then try
    and start up "olyvia" on an iPad (using different accounts), I get the following error message:
    "Cannot run more than one instance of this program simultaneously.  Either the program is already running, or it has not been terminated completely."
    I need to understand the root issue.
    1.  Is this a licensing issue?  So, I need to add some CALs to the RDS server?
    2.  Is this a application issue with "olyvia"?  So, no matter what I do, it is not going to be able to be used by more than one person at a time when configured as a remoteapp?
    3.  Did I not "publish" the application correctly?
    4.  Is this happening because I followed the "quick start" guide?
    Appreciate any help I can get on this.  We have no problem getting CALs, I just need some help with the root issue.
    Thanks,

    Hi Geoff,
    Each application uses different techniques for determining if multiple instances are running.  If you can determine what method it is using then perhaps you could use App-V or other virtualization software.
    In the best case you really should direct your question to the maker of Olyvia.  The reason I said that is they specifically designed their software to prevent multiple instances, so the first question is, why?  Is it related to Licensing? 
    Compatibility?  If you knew the specific reason(s) why they are doing it and the technique used then at the point using a virtualization technique may be the best option.

  • "A script is already running" while attempting to run more than one item

    We upgrade recently to ODT 11.2.0.3.20. Since then, attempting to run more than one item from the Solution Explorer (by selecting the items, right-clicking, and selecting "Run") results in a popup error of "Oracle Developer Tools. A script is already running". If many items are selected it results in many error messages and only a random few of the items are actually executed on the server. Also, choosing "Run On" now results in it prompting for the target database for each item selected (rather than once for all items selected like it used to). This all used to work fine in the earlier release we were using. Has anyone else run into this? Any fixes? We used to use multi-select and "Run" or "Run On" to deploy multiple items at once, but this no longer works -- doing one at a time works, but if you have hundreds of items to run, this quickly becomes unusable.
    Thanks for any insight.

    I don't believe that the intention was for you to be able to run a bunch of scripts one after the other. Often there are dependencies between scripts anyway and so you you have to order them. Because we're generally deploying a large set of stored procedures (and not just one-time scripts) the order doesn't really matter -- even if a stored procedure gets created before one it depends on, once all the SPs are on the server, the ones that are "invalid" will compile correctly once you execute them.
    I think a lot of people are creating master scripts that references child scripts using the "@" sql plus syntax.... have you tried that?
    I'll give that a try as a work around. Only issue I have with that solution is every time we add or remove something from the solution, we also have to update the script.
    We are doing a lot of enhancements to our script generation in the coming year. Keep an eye out for a beta to test.
    Like I said, this used to work fine in the older versions of ODT. It seems like the new version is attempting to execute multiple items at once on the same connection simultaneously, thus resulting in the "A script is already running" error. The old version used to be smart enough to execute them one at a time -- so something changed in a more recent version to completely break "Run" and "Run On" when you have more than one item highlighted (even just highlighting 2 items and choosing "Run" runs the first item, but then gives the error for the second item).

    That means you have 2 instances running an enque process, even tho this is possible i don't think is meant to be in your system... you need to check why?
    Check that parameter rdisp/wp_no_enq  is not set in one of the application servers.

  • When will this thing run more than one app at the same time?

    When will we be able to run more than one app at a time?

    As has been suggested, we won't know about future features until they announce them, but by understanding the current situation we can guess.
    The current limitations on third-party applications running in the background make sense. It's not a technical limitation. App store downloads, and the phone functionality run in the background while other applications are up front.
    It's a resource limitation. Processor power and probably more importantly battery life are the key limiting factors. It's not that Apple doesn't want you to have more functionality. It's that it currently struggling to deliver a quality experience that satisfies as many customers as possible. As it is the battery life is only just acceptable enough for most current customers, many are unhappy with it.
    So if more efficient chips or batteries become available, or some genius programmer manages to squeeze out a whole lot more out of less, then we'll see more background processes allowed.

  • Possible to run more than one iDVD at one time?

    Hiya, I'm currently running a nice shiny QuadG5 and when running iDVD6 I've noticed it doesn't use all the resources my machine has to offer (it usually hovers at around 130% out of 400%). Does anyone know if it's possible to run more than one instance of iDVD06 at once? I was thinking about creating a copy of the whole iDVD app and seeing but it's running a render right now so i can't disturb it. Seems a shame to have those yummy G5's sitting there doing naff all.
    cheers, Dave

    on my other hp scanner and copier i could set the no of copies i wanted. on this one i cannnot find that option.
