Error handling process

Hello

I started using a process to manage the final DB in our APEX applications transactions as I used to use a validation and a process with the null value; because error of process management is not very friendly to provide error messages.

I have little of which here is a code snippet
declare

  ex_error         EXCEPTION;
  v_Value          NUMBER := 0;

begin
  for i in 1..APEX_APPLICATION.G_F01.COUNT loop
    v_Value := APEX_APPLICATION.G_F01(i); --Radio group
  end loop;

  IF v_Value = 0 OR v_Value = '' OR v_Value is null THEN
    :P10_MESSAGE := 'You must select an item';
    raise ex_error;
  END IF;

  :P10_MESSAGE := 'Process worked ok';

end;
IM wondering the correct way to handle errors in a display of a dynamic error message depending on where the code ends. I tried to assign an error message I'll on a hidden item P10_MESSAGE and then use it in the message of success and failure as & P10_MESSAGE. but the value assigned to the hidden element does not show, as if it has been lost due to the exception raised, if the code works however the hidden element displays the process worked ok

Request Express 4.1.0.00.32

Since you are in 4.1, why not use the [url http://docs.oracle.com/cd/E23903_01/doc/doc.41api /e21676/apex_error.htm#BGBEEGIB]apex_error

You can not only set your own level of demand and the error handling page.
But ADD_ERROR procedures give you the possibility of an increase in errors customized with personalized messages.

  • Multi-threaded error handling method

    I have a multi-threaded application.  When an error occurs in one of the wires causing the failed system, all threads will raise an error and display an error dialog box.  I think on the withdrawal of the appeal to the error handler in the secondary threads and instead send the error for the main thread to the provision.  Is this a common model?  Is there a better way to do it?

    Not as common as it is MUST.

    We use a logger who passes all errors to a background process that connects to produce for examination later. This is the minimum. If a fatal errors then adjust us the design of the application respond accordingly when bad things happen.

  • Return 200 status Code error handler

    Greetings,

    I have a section of my site assigned to be a "Error Handler", but when a user is brought to this page, the status code is a 200. As you can imagine, this has the potential to cause a lot of problems for processes that are based on work status codes.

    I found the following solution on another site, indicating to put that code Idoc Script at the top of the Page Template:

    <!-$setValue ("#local", "ssChangeHTTPHeader", "true") - >

    Unfortunately, doing the above does not work. Am I missing something?

    Any help is appreciated. Thank you!

    I'm sure there's an easy solution here, but I can't find it on my box.

    Using Apache as a front end? They you could use mod_rewrite to redirect to a 404 page if a specific header exists in the answer. If you could put this on your error page:

    And then you have this in your Apache config file:

    RewriteCond% {HTTP:HTTP_FOUR_OH_FOURED}

    RewriteRule. * /not/ - found.htm [R = 404, L]

    More available here:

    mod_rewrite - Apache HTTP Version 2.4 Server

    allows hyphens. Obviously TUXEDO checks the internal Web address syntax.

    But I don't know why my IP (10.57.70.246) has failed.

    In any case, the issue is resolved. Make sure that TUXEDO documentation recommends-

    When using the name of the server host you talk server. This is case and sensitive syntax. »

    Where as: I changed my host name of psoft_pc to psoftpc and I changed the same on TNSNAMES and everything worked without problems.

  • ODSI - error handling

    Hello

    Can anyone here please suggest best practices to implement error handling in ODSI Data Services.

    Thanks in advance.

    Concerning

    You don't have to do anything.

    If your data service is exposed and called as a web service, and an exception occurs, your customer will get a SOAP fault that contains the exception that is thrown. You expose a dataservice (file musician) as a web service by right-clicking-> create web service card. You can test the .ws generated from the context menu. Here, I made a mistake by changing the name of the table:

    If you don't like what that looks like, you can use a failover (expression, alternateExpression) and use fn - error () as the alternateExpression with your own message. Below, I wrapped the getADDRESS() function with my own getADDRESS_MyError() function.

    (: function pragma ::))

    declare function f1:getADDRESS_MyError ($pk as element (t2:CUSTOMER)) as element(t1:ADDRESS) *))
    {
    FN - bea: fail-plus (f1:getADDRESS ($pk), fn:error (xs:QName("I_WANT_MY_OWN_ERROR"), "something bad happened"))
    };

  • Expand the error handling in AIA

    Hello world

    We explore the installation Error Handling Extension to AIA. For the use of this facility, I guess we need to create a custom listener to listen heading error AIA. What we intend to do is create a BPEL process that listen to this topic and run custom here logic. What we are not able to find are the details of this error AIA topic needed to configure the adapter in BPEL. Where can I find details on the subject of the error?

    Thank you

  • Yahoo solution DNS error handler

    I tried to go through all the things I could find after searching it upward. Most links, pages (for example, my Bank) and same plugin page is just finish on this DNS sokution yahoo error handler. It happened after the most recent update, and it really bothers me. more than 50% of the time, I have to change to another browser just because of this.

    Hello, randomn, you probably have an extension that modifies searchers, try Firefox Safe Mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Mac: Hold the option key during the startup of Firefox.

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

    Thank you

  • Receive a DNS Solution Yahoo error handler Page and some pages are not displayed

    I recently downloaded the Stuffit Expander and since then Firefox has not been the same. I get a DNS Error Handler Solution Yahoo page, when I do a search sometimes. And now, some pages don't display even for me when they should. How can I get rid of this thing of Yahoo (in simple terms please)? Thank you!

    You can have an unwanted extension that modifies researchers. Try this:

    Disable all non-essential or unrecognized extensions on page modules. Either:

    • Command + shift + a
    • Tools menu > Modules

    In the left column, click Extensions. Then, when in doubt, turn off. (Or if it is obviously the badware, delete).

    Typically, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

    Who help me?

    Note that when you search from the address bar of Firefox, searches that contain no spaces are checked as possible (e.g., intranet or my.web.server) server names. Most of the servers DNS don't report just "no server" and Firefox bounces the query to Google. However, some DNS servers say Firefox, they found the site and display the search results. This could be what you see. If it is new, maybe your DNS servers have been changed? (Don't know how to check on Mac).

  • find errors returned by the error handler simple vi

    When running the application in the development environment and after the application of the error handler code, I found would be Manager of simple errors that VI is a few errors which I do not know where on the block diagram the source code. Is it possible to find it?

    Kind regards

    I think I have strength to my self more clear in my post earlier. So here's the explanation:

    I have a few variant to the data functions in the while loop of a block diagram. When I now run my code after the implementation of the code of error handler I get errors. One of the ways I could think now to find which variant of function data is wired content type incorrect data is to run the vi Analyzer and find in the report generated by the vi Analyzer.

    Lets see how it goes.

  • Error handling and the basic flow data

    Hello

    I'm learning the basic error data and flow management. The seal is a simple VI to implement this.

    How do I implement this code to display an error.

    Thank you.

    You must assign a value of your choice for the cluster of error - in errors generated by the LabVIEW functions, error is already assigned/etc, but to find user customized errors, the user must assign values.  Just make sure you do not use the same error values that LabVIEW uses for predefined errors. If you do a search for error codes, you will be able to find this error varies from code - so pick something that is not already used.

    And Yes - using an error handler would be a simple way to accomplish what you're trying to do. This error handler will appear a message error only if your feature will remain smooth.

  • General error handling question

    So far, I've been able to intercept errors if I standard VI of wire in order (for example file IO) and handle errors in this way.

    Can I really take my code for errors without such wiring?

    For example, write on the Board that VI is not a mistake. If I leave the path to the empty file, I get an error, but no way to catch them. If my sub - VI generate errors and error ports, I'm fine. If they are not, I have no means to capture the error. Is this correct?

    Is there a way magic of creating a cluster of error with a TRUE value whenever an error anywhere (main or sub - VI), or is it wishful thinking?

    Thank you!

    If you want the treatment of errors in the file IO, you can make your own using the lower level file tools. They have all the error handling.

    You can open the worksheet screws and inspect the code if you wish. Make bring changes, then save them under a new name.

    Also do not forget that it is the management of automatic errors (enabled by default), then the screws worksheet will trigger a popup of error (most often unwanted!) if it occurs inside.

    Many functions have no errors (for example more basic numeric operations) and a lot of mistakes is not relevant. You should try to catch errors that really matter. Do not forget that the tail all a thread long error will require sequential operations and prevent so potentially the compiler optimization and parallel execution on multicore systems. One of the great powers of LabVIEW is the ease of parallel, simultaneous operation, so do not too throw a lot of sand in the gears.

    And, to answer your question, there is no magic way to add function error hydrants that isn't them. You can however wrap them in your own subVIs where you have sanity check on entries and exits, go into/out of the function without error. (for example check because "not a path" out "write on a spreadsheet file", empty array that comes out 'read the worksheet file', and/or place an explicit 'file dialog' in front of them and grab the flag cancelled, etc..)

  • Matlab script error handling

    Hello!

    I'm using Labview 2012 SP1 and I wrote a Matlab scipt to draw a Gaussian curve adjusted on a chart of the histogram.

    In some extreme conditions, the shape of the histogram prevents the Gaussian fit to be correctly calculated and Matlab throws an error (see attachment) displays in a pop-up window.

    The error is perfectly understandable, but I want to set up and to avoid the pop-up to appear.
    I wired the error so that the error text is showed in an appropriate area of Labview, the Gauss curve is not established and does not execute any code that follows in series.

    However, the popup will always appear.

    Is it possible to avoid it?

    Thank you!

    Best regards.

    Michela

    Is this something that you can recover from easily? If so, use ungroup by name to unbundle your cluster of error.  From there, you can wire the digital in a housing structure.  With this, you can have two cases: one with the error code and the other as a default value.  With the case of error code, you place a 'Clear mistakes' Vi inside and the error in this cluster and out across the wire.  In the default case, wire you the straight through error.  In this way, you disable only this one type of error.

    In 2014 or newer, the VI clear mistakes takes a digital input to ignore all the fun of the box structure.  But it's the same result.  You clear the error that you expect and that you can manage.  There is almost always a way to write your own error handling.  It depends on what exactly you need to do to recover from the error.

  • SEH, Structured Error Handler, still working in LV2014?

    I am using the SEH or try using I should say. Communication to the Central error handler works fine, but I can't get the options retry or call VI to work even using the code example in the palette. I'm in 2014 of LabVIEW and I just a very small test VI to try options. The problems are in the specific error handler. I put the options retry 5 times and clear the error. VI of appeal is disabled for this test. The loop runs with the error appearing in the output during the first call, and the loop exits. Have I not the wrong combination of options?

    For the Retry option, you have connected in the number of loops in the iteration of entry?  If you want to do it again 5 times, the SOGD needs to know the current iteration.

    For the option to call VI, the only thing that comes to mind is if your path is incorrect.

    It would be useful that you can share the code.  Unfortunately, I can't open the files in 2014 so I'm limited to guess what might be wrong.

  • Custom error handling

    Hello

    I want to create an error handler custom in a model similar to the ErrorHandlerExample.seq file.

    In my case, I'll genereated errors in several different DLLs.  We try to avoid writing wrappers around dll functions to fill in the TestStand error strings.  However, this information is available by calling a 'get error message' function in the dll.  Since I was more than a dll and a handful that I will need to check for errors, I need to know the information about the step that caused the error.  Is there a way to get more information about the step that caused the error?  I have a dll function call that had the format:

    kiOpenVSA (StationGlobals.KiManager, StationGlobals.VsaSession, StationGlobals.VsaResourceString, StationGlobals.DisplayEnable, StationGlobals.SendInitCommands)

    Based on the parameters of the function call, I would be able to call the correct error handling function.

    Thank you

    Mike

    This looks like exactly what I need.  I'll try and let you know how it works.

    Thank you
