How to tell is Grand Central Dispatch is running

Hi, I just installed Snow Leopard and it is fantastic, runs much faster, but, I was wondering if there is any way to tell if Grand Central Dispatch is running, I have been reading about it and was wondering if it was installed when SL was installed. Can anyone shed light on this?

It's built into Snow Leopard.
It's a tool developers use to write code to take advantage of multicore processors.
It is not obvious to the user, nor can you "see" it working, but it is there.

  • Turn on Grand Central Dispatch?

    I recently upgraded to snow leopard. I have read on the Apple website Grand Central Dispatch will take advantage of both cores to make my computer more efficient at running tasks. Do I have to set up Grand Central Dispatch to do this, or does it just automatically do what it needs to in the background?
    I have a Late 2006 iMac, 20", Intel Core 2 Duo, 2.16 GHz, 3GHz RAM, 64 bit.
    Thanks, Adam

    Hi PT1;
    I think if you check into Grand Central Dispatch a bit more you will find that it is an API to allow programmer to take advantage of multiple cores. It is not something you can turn on it. It is more a matter of find applications that have been coded using GCD so that they are multi-core aware.

  • How to tell embedded jinitator applet is still running when window closed

    Hello, we are trying to accomplish the same thing that is mentioned in this post from Metalink. I've searched for a solution and hope someone here can help. Instead of restating the issue I think David Wilson does a good job of explaining what is needed. Can anyone please suggest a possible solution?

    How to tell embedded jinitator applet is still running when window closed
    Hi,
    We run an oracle 10g forms application through 9iAS over an intranet. All users are running windows 2000 professional.
    We run separate frame = true but I would like to switch to separate frame = false
    With separate frame = true if the user clicks the outer windows "X" close button (forms mdi window) the user is prompted to save changes before the application ends.
    BUT
    when using separate frame = false
    If the user clicks the upper window "X" button (no longer form mdi window but regular browser window) the window and application is abruptly closed.
    I'm interested in using a onbeforeunload function to confirm if the user wants to close the window. This would be placed in the basejini.htm file. This could always ask if the user wants to exit or not. If they click OK then the window closes but if they click "Cancel" you are returned to the forms application exactly where you left. something like event.returnvalue="do you really want to exit?";
    However if the user exited using the normal exit form method then the applet is already closed before the onbeforeunoad event fires and there is nothing to go back to and I want the window to close automatically. This is accomplished using close.html file in post forms trigger.
    So what I want and what I think many may also want is the check if the embedded applet is still running and if so prompt the user to return to the application or continue to close. Of course If the applet is no longer running then just close because there is no reason confirm closing anymore.
    Does anyone have a html/JavaScript solution that can be placed in the jinitiator.htm file? or similar?
    Thank you
    David

    I don't know if this is exactly what you are after but you can add the following to the top of your basejini.htm file and it should prompt the user before exiting the IE window.
    <BODY %HTMLbodyAttrs%>
    %HTMLbeforeForm%
    <SCRIPT>
    <!--
    window.onbeforeunload = unloadApplet;
    function unloadApplet(){
    message = "Warning! Please exit the Java Applet prior to
    exiting the browser"
    return message;

    Subject: Re : How to tell embedded jinitator applet is still running when window closed
    Thank you for your reply and yes you did not understand my question fully.
    Sorry if this is a long reply
    I am able to close the browser window using information in notes 115905.1 and 201481.1, this is not the issue. We implemented this several years ago. It is workable for both separate frame = true or false.
    It is most important to not allow the user to end their forms application by closing the windows browser, they must close using normal form exit commands.
    What I want is to have separate frame = false, the big drawback to this option is the user can exit the application and bypass all forms code by pressing the windows "X" close button. This is why we need the code as just provided by Andrew Lenton above in this thread.
    BUT Andrew's code will always prompt the user before closing the window and I do not want that. I want the user to be prompted only under scenario 2 listed below.
    Here's the 2 case scenario for exiting the application.
    1. If the user closes properly and uses exit form which fires all normal form triggers including post_form with it's call to close.html file.
    All uncommitted changes are saved or rollback and the users session is ended normally both on the database and in the application server.
    All browser windows will close, great all is good. And without Andrew's code the window will close but with Andrew's code the user will be prompted to close or not, if they select Cancel the window will remain but the applet has already ended so why prompt? ...This is what I want to avoid.
    2. In the forms app. if the user clicks the windows "X" close button with uncommitted changes. The browser just closes the changes are rollback without prompting the user to save. The users sessions are now lost and still running in the database and application server until they are timed out.
    If I use Andrew's code then the user will be prompted to continue to close or go back, if they click Cancel to go back then focus returns to the forms application and the user can continue to work. If the user clicks OK then the window closes and unfortunately their sessions are still lost until timed out.
    So what I desire is to add to Andrew's code to check if the embedded applet is still running and prompt the user to close or not accordingly.
    Something like:
    Basejini.htm like
    </HEAD>
    <SCRIPT LANGUAGE="JavaScript">
    function maximizeWindow()
    window.moveTo(0,0);
    window.resizeTo(screen.availWidth,screen.availHeight);
    function confirm(){
    If(document.embeddedapplet.closed())
    Win.opener = self;
    win.close();
    Else if
    event.returnValue = "Closing Forms Application. OK to continue?";
    </SCRIPT>
    <BODY %HTMLbodyAttrs%, onload="maximizeWindow()", onbeforeunload="confirm()">
    %HTMLbeforeForm%
    I hope this explains my requirements.

    I'm sorry this is not helpful at all.
    Note 199928.1 is only an alert which does not stop the closing of the window and still displays as an alert if the user does close properly using exit form ... so why would you want to display the alert then?
    This is exaclty what I do not want and why I want to determine if the applet is still running before displaying any kind of message.

    Closing thread.
    Thanks,

    Hello,
    I had the same issue last year - wanting to provide a warning on closing the browser, but only if the Forms session is still running. The approach I took is described below, see also the thread where I originally posted this at Closing brower window
    Hi there,I've had a similar requirement - or rather, the two conflicting requirements: to warn when the browser is being closed, but for the app to be able to close the browser without a warning being fired.
    To always provide a warning when someone (the user or the Forms app) tries to go to a different page (e.g. your close.htm), use Javascript like:
    function confirmExit(){
    if(appletRunning==true) {
    msg="Closing this window or navigating to another page will end your SomeGreatApp session.";
    window.event.returnValue=msg;
    And make a call to confirmExit() in the onBeforeUnload event of your main page.
    You'll notice I first check an 'appletRunning' variable before displaying the warning. This Javascript variable is set to true by my app when it starts up, using an embedded Javabean that calls out to Javascript. Once that variable is set to true, then the warning will be displayed if the user tries to shut the browser by clicking on the 'x' button, or to go to a different URL.
    When my app is shutting down, it uses the same Javabean to set appletRunning back to false. It then navigates to a close.htm - which will be done without a warning being displayed.
    See Re: How can a Javabean call Javascript function of the basejpi.html?? for example code on how to call Javascript from a bean embedded in your Forms app.
    Hope these ideas help you out, it's worked for me (so far, anyway!!)

  • How to tell what version of htmldb is running?

    A while back I installed htmldb (now application express) on AIX 5.2.
    I think I used the Companion CD 10gR2 so thought that I had installed version 2 of htmldb. But when you log in it appears to show that version 1.6 is running.
    Is there a way I can tell for sure which version I have?

    David,
    The 10gR2 companion CD has 1.6 on it. 2.0 is a separate download.

  • How to tell if the app server is running (on windows)

    Folks,
    I'm trying to write a deploy.bat - to build and deploy (using ant) my enterprise-app and web-services (the firstcup example)
    ... I'm stuck on winblows (for now) ...
    The deploy depends on the app server... so if it's not running, I'd like to start it automagically... but I've fallen on the first hurdle... I can't figure out how your supposed to determine if the server is up.
    Please can anyone help?
    FYI: I had a bit of a play with the asadmin tool and found:C:\Java\src\Tutorials\Sun\firstcup\example\firstcup>asadmin version
    Unable to communicate with admin server, getting version locally.
    Version = Sun Java System Application Server Platform Edition 9.0_01
    Command version executed successfully.
    C:\Java\src\Tutorials\Sun\firstcup\example\firstcup>echo %ERRORLEVEL%
    0which looks promising... I can grep for the "Unable to communicate with admin server" (using a perl one-liner)... butt ugly but effective (for now).
    TIA. Keith.
    PS: There doesn't seem to be an application server forum???

    Folks,
    Firstly, Thanx for the underwhelming response :-)
    I've got a working workaround.
    I created a "hello world" webapp which I hit it from a CGI script.
    It should be (slightly) more robust (and portable) than grepping for error messages from the asadmin version utility.
    Shame I'm dependant on the "old hat" for the new goose though.
    Cheers anyway. Keith.

This should not be possible with 3.0 and very, very unlikely with 2.2.

  • How to tell if multiple files are selected when they are opened in windows

    Hello, can someone help me, my question is how to tell if multiple file selections were made when they were opened (right-click->open). Through modifying the registry I already have my Java program start up when a file with specific extension is double-clicked.
    The problem is when multiple files are opened at the same time, an instance of java program is created and run for each of the selected files. Ideally I would like it so that only one instance of java program is run, regardless of the number of selections.
    When you try it with Microsoft media player or winamp for example, it seems that only one process is created and run (I don't see many processes spawning when I watch it using task manager). Maybe this is more of Windows issue rather than Java programming issue. Any help is appreciated.

    If anybody wants to know, this can be solved by either 1) using DDE 2) using DropTarget (from Windows) 3) make a light-weight EXE dispatcher (eg. in C), and use file to have IPC between the dispatcher (which gets the filepath for each of the selections) and the java program. There can be other methods of course. Using the second option is the simplest but it requires WinXP and higher. I implemented it using option 3.. the downside of this is there's a warning message pop up when trying to open many (>20?) files at the same time by Windows. However, option 1 'seems' to have the same limitation. Having a java program created each time for each of the selections seems to be too slow, for viable option.

  • Bypassing Grand Central Press 1 prompt with PAP2-NA

    I am using PAP2-NA (Firmware Version: 3.1.9(LSc)) with the Gizmo Project and Grand Central. I am trying to bypass the Grand Central press "1" prompt on incoming calls. With Sunrocket Gizmo, the following is apparently the way to do this. What is the equivalent way of doing this with PAP2-NA? I see only 2 DTMF related options in PAP2-NA administration.
    ---DTMF Tx Method (InBand/AVT/INFO/Auto)
    ---Hook Flash Tx Method (None/AVT/INFO)
    I've tried all combinations of the above options but am still prompted.
    Approach with Sunrocket Gizmo from http://www.kalyansuman.com/2007/08/free-voip-with-gizmo-project-grand.html
    4) Change Gizmo settings using Telnet (to avoid press 1, 2 , 3 and 4 instructions on phone)
    Telnet into your Gizmo - Go to Command Prompt and type Telnet.
    At Telnet prompt - type 'open 192.168.251.1"
    This will prompt you for username and password - give 'admin' for user name and passowrd that you set in step 3.
    1) Press C2 and make sure RFC2833 (SDP and 2833 packets) is ALWAYS OFF
    2) Press Cs
    3) Look for Use SIP INFO for DTMF = Yes
    4) If it says no, then press c to change settings.
    4.1) Look for 18. SIP INFO for DTMF
    4.2) Press 18 to set it to yes
    4.3) Press y at the following prompt Use SIP INFO for transmitting DTMF digits?[y/n]
    4.4) Press w to write setting to Flash
    You should be now accepting inbound calls without needing to press 1, 2 and 3.

    Bump..I have the same problems (even worse) with my PAP2T-NA and GizmoProject/Grand Central. When I Click2Call (on GrandCentral) to my phone and some 1800 numbers, DTMF tones didn't work (such as Bank's menu) unless I used "DTMF Tx Method:InBand", and that solved the problem- but it created a new one. DTMF didn't work on Grand Central's menu (press 1 to accept, 2 to reject, and so on). So when somebody called me via GrandCentral, I couldn't answer the phone. I haven't found any solutions yet. I can't believe that I'm the only one who's having this issue. If SunRocket Gizmo is fixable with that, I think it should be addressable in PAP2T. Any suggestions? My current PAP2T-NA Firmware Version is 5.1.6(LS) (just updated). How should I fix it with these options? I need to get both of functions working. (To bypass the grandcentral "press 1" would be the ultimate goal only if the DMTF is working correctly.) DTMF Process INFO:Yes/No DTMF Process AVT:Yes/No DTMF Tx Method:InBand/AVT/INFO/AUTO DTMF Tx Mode:Normal/Strict Hook Flash Tx Method:None/AVT/INFO Thanks!

  • How to tell N6.5 DHCP to use a W2k8 for PXE?

    Hello,
    could anyone give me a hint, how to tell my netware DHCP to use a Windows Server 2008 R2 running Acronis with PXE Server?
    Actual Situation:
    Netware 6.5 Sp8 Server with ZENWORKS in Cluster mode
    Netware DHCP Server
    ZEN7 SP1 Imaging
    --> works fine so far, and no problem in other subnets, IP-helper are configured in the switches
    New Situation:
    Netware 6.5 Sp8 Server with ZENWORKS in Cluster mode
    Netware DHCP Server
    Windows Server 2008 R2 running Acronis Snap Deploy with PXE-Server - in future may be a clean Windows Deployment service without Acronis
    --> that would be nice :)
    I found serveral ini-files (dts.ini, pdhcp.ini, tftp.ini) where I configured the new IP-Address of the W2k8 PXE Server.
    Now:
    The Client gets its correct IP-Address from Netware DHCP
    but after that the following messages:
    Auto-select:
    ZENworks Boot
    Boot Server IP: --.--.--.-- (the correct one configured in the ini-files!)
    TFTP.
    PXE-T02:
    PXE-E3C: TFTP Error - Access Violation
    PXE-M0F: Exiting Intel Boot Agent
    Any ideas?
    Thanks a lot.

This option should only be set if both DHCP and PXE services are on the same server (as is probably the case in your situation as I'm guessing both DHCP as also PXE get loaded in the same cluster resource script).
    For subnets serviced outside of the subnet your DHCP server is running in, you will need to configure multiple ip helpers: one that points to the DHCP server and one points to the PXE server so those requests on other subnets get serviced correctly.
    To get things running it's probably easier to try to get this to work on the subnet your DHCP and PXE server are running in (so you are not also having to deal with the ip helper setup just yet). If that works, then expand you configuration to different subnets & ip helpers.
    Hope that helps,
    Willem
    As a ps and for clarification, don't load the PDHCP on any of the NetWare servers... just have the PXE PDHCP service running on the Windows server.
    The PDHCP/PXE service for ZenWorks won't understand/work with the Arconis one and visa versa.

  • How to get the Grand Total in Module pool Screen

    Hi Frds.
         How to get the Grand Total in Module pool Screen
    Example i have 10 different materials

    10 material Moving Average price to do Frand total and display in one column...
    Please Help me out Frds.
    Regards,
    Kabil

    Hi
    You need to calculate the total in a module of PAI (or PBO) event:
    PROCESS PAI.
       LOOP.....
       ENDLOOP.
      MODULE CALCULATE_TOTAL.
      MODULE CALCULATE_TOTAL.
        GRAND_TOTAL = 0.
         LOOP AT ITAB,
            GRAND_TOTAL = GRAND_TOTAL + ITAB-PWB.
        ENDLOOP.
    ENDMODULE.
    In this way the grand total will be calculated as soon as the user presses enter or another command.
    You can't insert the calculation in the loop of table control, because this loop runs the visible lines only, so it's better to calculate the total out of those loop,

  • How to tell if Im on AT&T?

    Hey guys. I guess I live right on the edge of an area covered/not covered by at&t. I have noticed that my reception bars have changed from black and white to colored and I have even seen a E next to it. So my question is how do I make sense of the different colors or letters so I know if Im on AT&T or some other network?

    how to tell if Im actually using at&T's own cell towers or a competitors.
    You will never be using a competitor's towers. A competitor would be T-Mobile, Sprint, Verizon, etc. and you'll never connect to their networks. You may in some cases be using an AT&T partner. In this thread, one poster advised:
    "To get an indicator when you are roaming on an AT&T partner network, call 611 and ask them to activate the (free) "Off Network Alpha Tag" on your account. If they ask why, tell them you want to be a good guy and observe the (usually unenforced) data limits while roaming."
    Hope that helps.

  • How to tell if REQ1 is set active high

    Hi I am using the 6533 PCI-DIO-32HS card in a PC with traditional DAQ, looking at an existing design.  I could not find how to tell if REQ1 is set active high or low, guessing it would be set up in the DIO confg vi.

    thanks for the additional information, yes will have to wait for the external hardware.  I did have a general question about the 6533 data and control line outputs using traditional DAC.  I think for this design it is set up as a pattern IO transfer using internal REQ and an internal clock set up as a VI input, (DIO START).  Anyhow I am monitoring the card outputs with a logic analyzer and it looks like an 8 element array (of 8 bit integers) is being used for the data input (to the DIO WRITE VI) with the first 4 elements being written out on DIOA0-A7, DIOB0-B7, DIOC0-C7, and DIOD0-D7 followed by the last 4 elements also written out to DIOA0-A7, DIOB0-B7, DIOC0-C7, and DIOD0-D7.  Anyhow it looks like the clock input to the (DIO Start VI) controls the pulse width of the data.  It looks like REQ1 goes high approximately 78 microseconds before the first 32 bits are written out followed by 5 microseconds of data (with the clock set at 200k), finally followed by the second data group (5 microseconds of data).  It then looks like REQ1 stays high for 2-4 ms after the second group of 32 bits is written out before going low.   Anyhow if you are trying to clock this data into a storage device I would expect to see rising clock edges when both the first and second group of data appear on DIOA0-A7..DIOD0-D7.  I monitored all the other control lines pclk1,2 ack1 and did not see signal levels other than 0, again I do not have the DIO card connected to anything except a logic analyzer.  Would you know if it is typical to use REQ1 as a clock input to a storage device or if this can be done?

  • [Forum FAQ] How to tell if the DAC port is automatically changed or not

    Introduction
    Per Books Online:
    http://msdn.microsoft.com/en-us/library/ms189595.aspx
    SQL Server listens for the DAC on TCP port 1434 if available or a TCP port dynamically assigned upon Database Engine startup.
    Also, we can go to the following registry to specify the DAC port number manually:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQLServer\SuperSocketNetLib\AdminConnection\Tcp
    The error log contains the port number the DAC is listening on. Besides looking at the error log, how to find which port is used by DAC connection and how to tell if the DAC port is manually set by us or assigned automatically by SQL Server?
    Solution
    The following query can be used to check if there is an existing DAC connection and it also give us the port number used by dedicated admin connection.
    SELECT name,local_tcp_port FROM sys.dm_exec_connections ec
    join sys.endpoints e
    on (ec.endpoint_id=e.endpoint_id)
    WHERE e.name='Dedicated Admin Connection'
    Here is the scenario to test if the DAC port is automatically changed or not.
    There are two instances are running on one server. I specified the same DAC port number 5555 for the two SQL Server instances by modifying the registry
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQLServer\SuperSocketNetLib\AdminConnection\Tcp
    Opened the DAC connection to instance 1. Executed the above query, it returns the result:
    name                                                  
    local_tcp_port
    Dedicated Admin Connection               5555
    Then, opened a DAC connection to instance 2. It throw out the following error message:
    Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Client unable to establish connection because an error was encountered during handshakes before login.
    Common causes include client attempting to connect to an unsupported version of SQL Server, server too busy to accept new connections or a resource limitation (memory or maximum allowed connections) on the server..
    Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : TCP Provider: An established connection was aborted by the software in your host machine..
    Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Client unable to establish connection.
    Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Client unable to establish connection due to prelogin failure.
    The above error message was thrown out because the DAC port number 5555 was not available for instance 2 which was occupying by instance 1. After restarting the SQL Server engine service of instance 2, if checking in the registry, you would see a new DAC port
    number has been assigned to the second instance.
    Then, the DAC connection to instance 2 succeed this time and executed the above query, it returned the same port number which is same as the one in the registry key and the port number was assigned automatically.
    DAC port will not change even SQL Server service is restarted only if the TCP port is available.

    I tested your script after
    establishing a DAC connection from SSMS 2014. It worked as described. Thank you.
