2.1 EA2: Does anyone know what the units of time are in unit tests?

Hi all,
I've been running some unit tests in SQL Developer EA2, and am curious about the units of time that I see in a couple of contexts; if anyone can enlighten me I would be very grateful...
(1) I have my unit test defined to "Gather Code Coverage Statistics"
(2) When I run a test, the results tab shows "Status" and "Duration" columns - what does "Duration" mean here? For example, my test shows "1,826" - is this milli-seconds of processing time? Any other clues?
(3) I then look at the "Test Runs Code Coverage" report, and click on the appropriate entry in the top section of the screen, which shows me the "Code Coverage Details" view
(4) I can make sense of the "Line", "Text" and "Total_Occurrences" columns, but what does the value in the "Total_Time" column mean here? For example, for simple SUBSTR assignment operations, I see a "Total_Time" of "1201", is this micro-seconds, nano-seconds?
Many thanks in advance,
Chris Hughes

Hi Chris -
(2) Duration is in milliseconds (1/1000 sec) (this is the time from the client perspective for each operation)
(4) Total_Time is in nanoseconds (1/1000000000 sec) (or at least that is what the documentation about plsql_profiler_data.total_time (where we get it from) says ;) )

  • Hiya, I've got a weird problem with my iPhone4. On the 'home page' of my iPhone the mail symbol tells me there's a new mail waiting for me. However, there's no new mail to be found. Does anyone know what the problem is? Thanks

    This response is a little late as I just read about your problem. I have a 2012 Dodge Charger and a 2012 Chrysler Town and Country and both worked flawlessly with the iPhone 5s my wife and I had. However, we just upgraded to the iPhone 6 and Uconnect will receive calls but you cannot answer them. You can callout successfully, however. the annoyance being the inability to answer incoming calls in the HandsFree mode.

  • Does anyone know what the "Provision Failure: MEDIATION-5, Lrad! errors are in WCS

    Does anyone know what the "Provision Failure: MEDIATION-5, Lrad! errors are in WCS? 
    I get this when pushing an AP template to six new 3502i series access points.  The error reads like this:
    *** Apply Result for AP 'NameOfAPhere(C0:FF:EE:C0:F:EE)' ***
    **AP Parameters**
    Provision Failure: MEDIATION-5, Lrad!C0:FF:EE:C0:F:EE,secondaryMwar,No access
    MAC address has been changes to protect the names of the innocent...
    The rest of the template appears to push.  The 802.11a/n and 802.11b/g/n parameters show "success".
    Anyone have the magic decoder ring for what these messages are referring to so that I can go fix the issue?
    Thanks in adavance!

    Hi,
    Two things :
    1- Can you refresh configs from WLC to WCS and then give it a try ?
    2- Is WCS using the right read-write community string for this WLC ?
       (Since we see a "No Access" message in the error)
    Thanks..Salil

  • On my Mac Mini, I keep getting this error message: "iCloud encountered an error while trying to connect to the server".  I don't have any problems with iCloud on my laptop / PC.  It works fine... Does anyone know what the problem could be?

    Your Mac must be on Lion (10.7) to run iCloud. Apple had to change the operating system to fully support it. Nevertheless, it is possible to get emails from iCloud without having Lion. Please tell me if this interests you.
    Anyways, here is the link to buy Lion (30 dollars, totally worth the upgrade ): http://itunes.apple.com/be/app/os-x-lion/id444303913?mt=12

    Your Desktop Picture settings and Dock items are stored in the files
    /Users/your short user name/Library/Preferences/com.apple.desktop.plist and
    /Users/your short user name/Library/Preferences/com.apple.dock.plist
    in the "Preferences" folder in your user library. This looks like the system has trouble to write to these files. Check the permissions on your user library and remove the above files from your user library, then log off and on again.
    Your user library is hidden in Lion and Mt. Lion. To reveal it, use the Finder's "Go" menu. Select "Go" in the Finder's main menu bar and hold down the alt/option key, until you see the "Library"  in the drop-down menu. Double click it to open a Finder window, so you can browse the files inside.

    Hi, oldcrow13.
    Thank you for the response.  Typically this error is caused by installing an older verison of iTunes than you had prior.  When you installed iTunes did you download the program directly from iTunes.com, or did you use an older copy of the program on your computer?  If you used an older version or are unsure, uninstall all the components one more time and download a new copy of iTunes via the link below.

  • Outlook 2007 doesn't show icloud service running.  Does anyone know what the dll for this service is so it can be manually added to outlook?

    Outlook 2007 doesn't show the icloud service running in Windows 7 within outlook.  Does anyone know what the dll for this service is so it can be manually added to outlook?   I've installed the icloud control panel app and set it up to synch everything, but after initially downloading my icloud calendar, it won't process any calendar updates (new entries made on either iphone 4 on ios 5 or outlook). 
    So since the control panel installed, but the service doesn't show running in outlooks "trust center" add-ins list, anyone know the actual dll file it would point to so I can see if I can add it the hard way?

    I had the same issue and figured it out.  First you have to start Outook as administrator.  To do this, shift and right-click on outlook and click run as administrator.  Next you need to enable Hard-disabled add-ins:
    Hard-Disabled Add-Ins
    Hard disabling can occur when an add-in causes the application to close unexpectedly. It might also occur on your development computer if you stop the debugger while the Startup event handler in your add-in is executing.
    To re-enable an add-in
    In the application, click the File tab. 
    Click the ApplicationName Options button.
    In the categories pane, click Add-ins.
    In the details pane, verify that the add-in appears in the Disabled Application Add-ins list.  The Name column specifies the name of the assembly, and the Location column specifies the full path of the application manifest.
    In the Manage box, click Disabled Items, and then click Go.
    Select the add-in and click Enable.
    Click Close.
    Then you need to activate it. 
    To re-enable an add-in
    In the application, click the File tab.
    Click the ApplicationName Options button.
    In the categories pane, click Add-ins.
    In the details pane, verify that the add-in appears in the Inactive Application Add-ins list.  The Name column specifies the name of the assembly, and the Location column specifies the full path of the application manifest.
    In the Manage box, click COM Add-ins, and then click Go.
    In the COM Add-Ins dialog box, select the check box next to the disabled add-in.
    Click OK.

  • Does anyone know where the iWeb data files are located or what they are called?  I can't find them.  I looked in Finder for files named the same as my website, but found nothing.  Any help would be appreciated.

    Does anyone know where the iWeb data files are located or what they are called?  I can't find them.  I looked in Finder for files named the same as my website, but found nothing.  Any help would be appreciated.

    If you erased or replaced your hard drive since iWeb was cancelled, then they are gone. Otherwise, if you have maintained backups then check those.
    Usually such files are in the /Home/Library/ folder or a sub-folder.
    Exposing the /Home/Library/ Folder
    Pick one of the following methods:
    A. This method will make the folder visible permanently. Open the Terminal application in your Utilities folder and paste the following at the command prompt:
    chflags nohidden ~/Library
    Press RETURN.
    B. Click on the Desktop, press the OPTION (⌥) button, select Library from the Finder's Go menu.
    C. Select Go To Folder from the Finder's Go menu. Paste the following in the path field:
    ~/Library
    Press the Go button.

  • With the new iOS 7 update, does anyone know what the setting "Bold Text" will do? If you click on this, it says it will restart your iPhone. Before I do this, I'm just wanting to be sure I know what's going to happen.

    With the new iOS 7 update. Does anyone know what the setting "Bold Text" means or will do? Obviously I do know what Bold Text is. It says if you click on this, it says it will restart your iPhone. Before I do this, I'm just wanting to be sure I know what's going to happen.
    Thanks,

    It just reboots the device and bolds the system fonts.  No harm done.  If you don't like it, undo the setting, it will reboot and back to as it was.

  • Does anyone know what the second button is for on the logic board of an iMac G5 (PPC), 1st generation ?

    One button on the logic board of a 1st generation iMac G5 (PPC) is an alternate power button. Does anyone know what the purpose of the other button is?

    I am far from certain but I believe it is the power management unit (PMU) reset switch a/k/a Cuda switch: http://support.apple.com/kb/HT1939
    Do not press it when the computer is on.

  • Does anyone know what the default font is for MacMail?

    Does anyone know what the default font is for the Mail program? My son changed my mail font and I want to change it back, but I can't remember what the original default is! Anyone? Thanks!

    I rarely use Mail (normally use Gmail in Safari) so I am 99.99% sure mine is still at the default. It is Helvetica 12.

  • Iphone6 doesn't play music (have tried obvious things like volume etc and plugged in headphones, connected to a speaker via bluetooth, and tried to play from the inbuilt speaker). Does anyone know what the problem is and how it can be resolved?

    You can't buy the part from Creative as a spare.
    I'm not sure how compatible other parts might be, but that would be a question for someone who really knows a lot about this area of electronics.
    The Creative repair for this is likely to be expensi've, but the problem is most likely a broken solder connection than an actual new headphone socket. So if you know someone experienced in surface mount soldering you could probably get it repaired just with this.
