The 1142n controller code

Just got some 1142n points. We have a controller 4402, but also a WISN. All controllers are running 4.2.176 code. I know, I need to run code 5.2 to the 1142n support. There are currently two versions of the posted 5.2 code. 5.2.157 and 5.2.178. I thought keeping the WISN 4.2 code and just upgrade the controller 4402 5.2 code to support APs 1142n. The 4402 controller is in a group of mobility with the WISN. If I run mismatched version code is it best to break the 4402 to its own group of mobility or just ensure that the APs on the 5.2 4402 have never the WISN as a secondary residence.

I was under the impression that 5.X code was not stable enough to start production. With the 1142 s, we have little choice. Is stable enough to operate on all the controllers of 5.2 or do I have to wait on that for the WISN.

It should be good. If you have problems, you can always restore your FW.

Make sure that you run also true bootstrap (4.2.112.0) emergency release version plus (5.2.157.0 ER).

The difficulty of your case is when you run the new codes on a WLC in order to support the PA 1140, what will happen if this controller fails? The AP would find the next controller and unfortunately it runs an unidentified code then 1140 would probably go... nuts?

  • pageButtonBar don't train not move to Page 3 without the controller Code.

    Hello

    I'm practsing Train updated the OAF tutorial that comes with the Patch of the EBS R12.1.3 OPS.

    After you have created the 3 pages, I created a page EmpTrainRN.xml (train style) with 3 TrainSteps of type link. I have no problem in visiting all 3 pages by clicking the bullets next to each step.

    I also have EmpTrainFooterRN.xml (style pageButtonBar) with a navigationBar including = 1 step and the last step = 3. (The Destination URI has been set correctly).

    After the launch of the first page, I am able to visit the second page by selecting the next button. But when I click the button following once again, the same 2 page is being updated - rather than page 3 launched. This is not the expected behavior.

    However when I put the code below in the processRequest controller (for EmpTrainFooterRN), I am able to move on to page 3 using the next button.

    OATrainBean trainBean = (OATrainBean) pageContext.getPageLayoutBean () .getLocation ();

    trainBean.prepareForRendering (pageContext);

    step int = trainBean.getSelectedTrainStepRenderedIndex ();

    OANavigationBarBean navBean = (OANavigationBarBean) webBean.findChildRecursive ("NavBar");

    navBean.setValue (step 1);

    This piece of code is not present in the tutorial Oracle OAF, but I found this by reseraching, Web site at

    https://blogs.Oracle.com/prajkumar/entry/implement_train_in_oaf_page

    However, I tried the tutorial to Train at the below Web site that does not use any Code from the controller, but it enabled navigation on page 3 using the next button

    http://www.yesyespatil.blogspot.in/2013/11/creating-train-region-in-OAF.html

    Y available documentation explaining under what circumstances the step value should be increased in the highest maaner in pageButtonBar train controller, or anyone can shed some light on this.

    Thank you

    Hello Sanjay

    I found the problem and the solution.

    Your destination in the navigation links are wrong.

    First, they must begin by "OA.jsp? page =".

    Second, they must correspond with the destination links in the area of train.

    This is how the framework includes the relationship between the bar of navigation and train.

    In your application when I turn to the second page with a next button, navigation bar did not get updated. That's how I found the problem.

    Change your links as navigation bar:

  • failure of the graphics controller envy14t-1000 flashes code?

    For laptop of HP Envy 14-1000. i5 - 450 M, Radeon 5650 M. Out of warranty. New installation of Windows 8 Professional on an OCZ Agility SSD 4.

    At startup, caps lock flashes code indicates a failure of the graphics controller. Stays on for 2-5 minutes, but will then start Windows. This indicates imminent failure and a replacement motherboard is necessary, or is it the result of something else?

    On your laptop, there are several codes of different flashing given by a flashing caps lock key. You say that it is the graphical model controller failure error light. Use this document to make sure it is the correct error code.

    The ENVY of laptops series have their GPU soldered onto the motherboard. So if you've got a controller failure graphics card you might have to replace the entire motherboard of the laptop. This interview is possible to do it yourself, although difficult. Even if you specify your product is out of warranty, I suggest to contact HP Technical Support again and look in an interview of the laptop. If you are in the USA / Canada, you can contact HP at 1-800-474-6836. If you are outside the United States / Canada then here try to find contact information for your region.

  • Card PCMCIA Avaya on a machine Satellite Pro 4320 - 31 to load the driver error code

    The machine works perfectly in all respects. Recently attempted to add an Avaya Silver wireless card to the system.

    Somehow the system has problems with the supplied driver. I have redownloaded the driver support site (now on version 7.62, the driver should support the card as a "Avaya Wireless PC Card".) I have to the latest driver available.

    Given that the machine works under Windows 2000, SP4 and all available patches, and yet didn't have questions about installing a card like this on a Windows 2000 computer before, I'm a little confused as to what may cause the problem.

    The card is detected properly, and the pilot is recognized. When installed the Device Manager still representing a yellow exclamation mark on the map of Avaya. When investigating this error shows that Windows 2000 cannot load the drivers on an error code 31.

    I found Code 31 made reference to possible support material that gives the questions. I turned my attention to the CardBus controller (ToPIC100 according to Device Manager). The version used is Microsoft, 20/06/2003, 5.00.2195.6717.

    Appearantly it is a newer driver (5.1.2600.0) but I failed to bring one downloaded. Seems that it is only available through Windows Update, which does not show the update as being available for the machine.

    Then... Anyone know how to get the map Avaya Wireless Silver active PCMCIA on a Satellite Pro 4320? I need a newer driver, or can not be done at all?

  • Executable cannot find the custom error code file

    I'm building a LabVIEW 2013 application on a Windows 7 computer and deploying it to a Windows XP computer. My application has a custom error code file, stored in -- errors.txt, but my executable on the Windows XP machine can't find the custom error file and returns only the string of appeal for all errors that occur.

    When you use is not an installer, I tried to copy the error code at all locations listed here: http://digital.ni.com/public.nsf/allkb/6077DBEDA4F9FEE3862571F600449501 but the application still does not load the custom errors. I have the box checked to "Error Codes customized Include" in the construction specifications.

    When an executable of construction and the development of Windows 7 to XP, where do I put the custom error code file? It is found in Program Files (x 86), but find not because it's XP?

    It's been a few months that I posted this question and I do not know if someone cares about this track, but the solution I found was to put the custom in error code file \National Instruments\Shared\Errors\English\

    There are other places that the runtime will look for the custom error codes (I tried all the ones listed above), if the same error codes exist in 2 places the error popup will appear two error messages. Error default 1, it looks like:

    LabVIEW: An input parameter is not valid. For example if the input is a path, the path can contain a character not allowed by the operating system such as? or @.
    =========================
    NOR-488: Command requires GPIB controller charge controller.

    So if you have a custom error code file and it is available in 2 places that LabVIEW RTE check error codes, you will get the same message before and after the =.

    List the error as "still included" file when building the executable or by checking the box to include files in error did not tour, obviously. Unless you create a Setup program to distribute the application, the error code file must be moved manually. Shared\Errors file works best for me because it's a place that makes sense.

    Also, don't worry - it doesn't me taken 5 months to understand this point, I do not update all my loyal followers (ha) with a solution.

  • Excel sheet entry to 'setpoint' of the PID controller

    Hello

    I use this (attached) vi to control the thermostat of Lakeshore. I got the website vi OR. I want to change the vi as to the set value, it takes as input an excel sheet (could be any other form too). This spreadsheet contains a list of temperatures. The vi reads the first temperature and then that sets the value of the PID controller setpoint. Once the set point is 'set' the vi waiting for awhile (say 1 hour) before reading the next entry in the excel sheet set point. I want to wait that it is because I programmed a gamma spectrum software such that it counts for 1 hour and then starts a new count. The part of the spectrum is not very intelligent but its ok for now. The problem I have is that when I run this vi (attached), the indication of the set on the temperature controller (hardware) tends to zero and stays there. Can someone help me by pointing out the error that I do. This vi is Labview based 6.0 (it's a bad implementation!)

    Thank you

    Saurabh

    Slim,

    You could possibly have the calendar in step in the worksheet as well?

    It would be a classic case where you could use state machines (or producer / consumer - events if the user input is critical), research of this architecture and examples on ni.com. Also for synchronization purposes, are looking for functional global timer or try to modify this example https://decibel.ni.com/content/docs/DOC-6523 to add 'elapsed time' (as in the elapsed time express vi) features similar to this code.

    You have reports such as:

    Initialization: initialize your control panel front/graphics etc. Read the spreadsheet file. Make sure that the comms exist between the software and the controller, etc..

    Set the temperature: set the first value, start a countdown (depending on what you set)

    State check: check the status of controller etc failure. Check if the user has pressed the stop button. Check if the timer in the previous state has expired?

    In case of error stop the timer and take the measures necessary to correct, to report to the user

    If the user has pressed the stop button, close all references, etc hard reset and exit the application.

    If the timer has expired, get the next value and go on to set the temperature.

    I hope this helps.

  • migration of APs to the 5508 controller 4402

    Hello all,.

    We have two controllers (4402 and 5508) to one of the site.

    Customers of services at present.

    Both controllers have the same set of SSID but uses only a single group of AP.

    What would be the best means to move APs on 4402 to 5508?

    4402 services series years 1230 and 1240 AP. And looking at the note accompanying the WLC 7.6 code located on 5508,

    years 1240 only are supported. So, we will need to get the replacement of the years 1230.

    Someone suggested to go into every single years 1240 and change high availability for point to 5508 as primary and secondary 4402

    (just in case the AP don't is not the controller) 5508 Once this is done, I can add the AP in the access point default of the group to broadcase the same SSID.

    Is it enough for the task of migration?

    Also, what is the requirement of default design for the number of necessary uplinks?

    We have about 150 APs currently on 5508 that uses Group LAG of 1 4 uplinks.

    Regarding the 4402, it is service 60 APs with 1 2 uplinks.

    Thus with the APs on 4408 joining the 5508, 5508 serves about 210APs. 4 1 enough uplink is?

    What is the best practice recommended requirement of uplink AP?  APs on 5508 are 3602 s and 3702 s.

    Thank you in advance.

    P.S. BTW two controllers are part of the same mobility group

     Someone suggested going into every single 1240s and change the high availability to point to 5508 as primary and 4402 as secondary.(just in case the AP does not join the 5508 controller.) Once that is done, I can add the AP into the default AP group to broadcase the same SSIDs.Is that enough for migration task?

    Yes, it is sufficient. Unless 5508 have the same available on 4402 AP group name, all years 1240 migration goes into default-group & you may need to add to the good group of AP. It is advisable to have same AP group created between the controllers where AP configured for failover.

    Don't forget 1240 last took in charge in 8.0.x code. In order to better plan as well before moving on to 8.1 replacement code (expect less than 1-2 months of time). See below for more details compatibility matrix

    http://www.Cisco.com/c/en/us/TD/docs/wireless/compatibility/matrix/compatibility-matrix.html

     Also what is the default design requirement for the number of uplinks needed? We have about 150 APs currently on 5508 which uses LAG group of 4 1G uplinks.Thus with APs on 4408 joining the 5508, 5508 will roughly serve 210APs. is 4 1G uplink sufficient? 

    4G LAG is more that sufficient for 250 AP, I'm sure that together the traffic will be much less of 4G if monitor you the traffic volume of the art on this trunk links.

     What is the best practice recommended AP to uplink requirement? APs on 5508 are 3602s and 3702s.

    I guess that all of these AP connected to 1 Gbps switch compatible PoE ports +. If your binding rising intercommutation is 1 Gbit/s, which would be the bottleneck, WLC to SW LAG before becoming a bottleneck.

  • Remove the SCSI controller change question of VMWare

    Hello

    I used PowerCLI for create a virtual machine and replace it with instead of buslogic SCSI LSILogic controller. I did it by using the following code:

    function updateSCSIController ($vmName, $ctrlName)

    {

    $vm = get - VM $vmName | Get-View

    1. Get the controller and devices on

    $vm. Config.Hardware.Device | where {$_.} DeviceInfo.Label - eq $ctrlName} | % {

    $oldCtrl = $_

    $ctrlKey = $_. Key

    $devs = @)

    $devKey = $_

    $vm. Config.Hardware.Device | where {$_.} Key - eq $devKey} | % {

    $devs += $_

    }

    }

    }

    1. Create the specification for the device changes

    $bootDelay = 10000

    $spec = new-Object VMware.Vim.VirtualMachineConfigSpec

    $spec. BootOptions = New-Object VMware.Vim.VirtualMachineBootOptions

    $spec. BootOptions.BootDelay = $bootDelay

    1. Remove the old controller

    $old = new-Object VMware.Vim.VirtualDeviceConfigSpec

    $old.device = $oldCtrl

    $old.operation = 'delete '.

    $spec. DeviceChange += $old

    1. Update the devices connected to the controller

    $devs | % {

    $dev = new-Object VMware.Vim.VirtualDeviceConfigSpec

    $dev.device = $_

    $dev.device.ControllerKey = - 100

    $dev.operation = "Edit."

    $spec. DeviceChange += $dev

    }

    1. Add the new controller

    $new = new-Object VMware.Vim.VirtualDeviceConfigSpec

    $new. Device = New-Object VMware.Vim.VirtualLsiLogicController

    $new. Device.Key = - 100

    $vm. ReconfigVM ($spec)

    }

    However when I try to start the virtual machine Via code, it gives me an error saying that the virtual machine has questions to be decided.

    This is the question asked by VMWare:

    sg.disk.AdapterMismatch: the disk attached to the node SCSI0:0 has been created for the Buslogic SCSI adapter but SCSI0 Virtual Machine device is a SCSI LSI Logic card.

    VMware ESX Server can change the free disc adapter type. Attention of the user, if a guest operating system is installed on the drive, it is perhaps not able to start.

    Do you think Vmware ESX Server to change the type of adapter for SCSI0:0 disk

    This issue can be removed through PowerCLI?

    This is the part of code that fails

  • Failed to create the reference to the FXMLLoader controller: "no constructor appropriate."

    Greetings,

    I'm in my first two days, experimenting with JavaFX.

    I am trying to create a reference to my controller class to in my routine of starting application. All the posts I've seen on this call to the code as follows:
     FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("MyFXML.fxml")); 
    But in my NetBeans IDE editor this code reports the error "no suitable constructor found for FXMLLoader (java.net.URL)."

    The documentation for the FXMLLoader class undeniably a constructor FXMLLoader (java.net.URL). However, when I access the NetBeans source code, this constructor does not show: the only options are FXMLLoader() and FXMLLoader (Charset arg0).

    I use NetBeans 7.1.2 ee version. I was using JavaFX 2.0, then downloaded the SDK 2.2 JavaFX (beta) to see if it would make a difference - she didn't.

    Any ideas would be very appreciated.

    Hello

    My guess would be that NetBeans resumes still jars of JavaFX 2.0 instead of JavaFX 2.2

    I would say that play with the properties of your project: examine the library dependencies and the platform.
    If you use a Default_JavaFX_Platform then check where it picks up JavaFX (click on 'manage the platform' and look in the JavaFX tab).
    Sometimes, NetBeans is confused and will resume the 2.2 SDK with the 2.0 runtime - check if really all paths!

    Hopes this helps,
