Latest Error Handling for Dynamic Actions

Is there any documentation on the Latest Error Handling for Dynamic Actions?

BillC,
Interesting that I was looking around for the same thing after seeing a Foreign Key violation in my application.
I found this article by Patrick Wolf:
APEX 4.1 – Error Handling Improvements – Part 1
http://www.inside-oracle-apex.com/apex-4-1-error-handling-improvements-part-1/
I believe you need to be on 4.1 or later though.
Thanks,

Error Handling for Dynamic Actions (4.1.1)

Hello
I'm trying to create a function to handle all possible errors but the errors generated by DA are not being caught.
Is it possible to caught them? How?
My function is based in:
http://www.inside-oracle-apex.com/apex-4-1-error-handling-improvements-part-1/
http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_error.htm#autoId4
and I'm making my tests in apex.oracle.com
Thanks

Hi,
there is no APEX JS function which you could use to intercept the error display. But you might be able to overwrite the "window.alert" JS function which is used to show the error with your own implementation. This function could check the text for some patterns and then decide what to show to the user. I haven't tried this but
var originalAlert = window.alert;
window.alert = function( pMessage ) {
if ( pMessage ... some check comes here ... ) {
originalAlert( "My new message" );
} else {
originalAlert( pMessage );
};might work.

Option for error handling for DTP, ' no updata, no reporting" and "deactiva

Hello Gurus,
     option for error handling for DTP, ' no updata, no reporting" and "deactivated" , please give some explanation and instance for them?
Many Thanks,

On the Update tab page, specify how you want the system to respond to data records with errors:
                            a.      No update, no reporting (default)
If errors occur, the system terminates the update of the entire data package. The request is not released for reporting. However, the system continues to check the records.
                            b.      Update valid records, no reporting (request red)
This option allows you to update valid data. This data is only released for reporting after the administrator checks the incorrect records that have not been updated and manually releases the request by setting the overall status on the Status tab page in the monitor (QM action).
                            c.      Update valid records, reporting possible
Valid records can be reported immediately. Automatic follow-up actions, such as adjusting the aggregates, are also carried out.

Error Handling for Outbound IDOC - COSMAS (Cost Center Master)

Hi,
I need to trigger a mail to SAP inbox whenever a outbound idoc fails for any reason.
I know how to do it for inbound or outbound transaction data, but not sure how to do error handling for outbound master data.
Could one of you help me understand the same.
Thanks in Advance,
Vinoth

Hey Vinoth,
Do you want decide the recipient of the mail dynamically? am asking because if you give the USER NAME in the partner profile and when ever a IDOC fails a mail will automatically reach the user inbox automatically
let me know if i answered ur question.
Thanks,

Error handling for work item

Dear All,
     When I trigger my workflow from SWUE,the workflow containers must be populated with agent name.But it is populated only with 'US'.Please suggest.
     On the other hand, when I trigger my workflow from ME21N,the workflow goes into error.The error statement is "Exception occurred - Error handling for work item 000000954797".What is the problem?
    Please suggest the solution for which I will be grateful.
Thanks and regards,
S.Suresh

Dear ,
I use bus2012 as BOR and event as created.
When I create purchase order from ME21N,bus2012 is not triggering.Instead FREBUS2012 gets triggered which is a subtype of bus2012.
At SWETYPV,event linkage is activated only for BUS2012 and there is no entry at SWETYPV for FREBUS2012.
Though I configured the workflow with start events:BUS2012->created,why FREBUS2012 should trigger my workflow which is not seen in SWETYPV?How to override it?Please suggest.
There is no start conditions for my workflow.Whenever purchase order is created,this workflow should trigger.
So,the parameters passed between even to workflow are
&_EVT_OBJECT&    ->        &BUS2012&
&_EVT_CREATOR&   ->     & WFINITIATOR&
Thanks and regards,

Error handling for a save button

hi. how do i get error handling say in a button, and then to give an error to the user, without crashing the whole application. can any one point me to any articles, tried searching , and not finding wxactly what i am looking for. thanks.
http://startrekcafe.stevesdomain.net http://groups.yahoo.com/groups/JawsOz

hi. maybe i did not make my self clear. okay, here's how this button works, you have a open dialog button, and a open dialog box, you click the file, and it loads in the data grid. now you click on the save button, and a message says file was saved, need
try / catch code, to catch this, if the file was not saved, or other errors, then a error friendly message, any code for this. read the article, but need a specific error handler for the save button, like i had for the open dialog file dialog box. any suggestions,
or links, to look at sample code. thanks.

Error handling for RGB values

Hi
I am having problems doing error handling for RGB values. I have a Java applet with 3 JTextFields whose values are parsed as int variables and stored as ints. If a value is entered that is not a value between 0 and 255 is entered, the appropriate field/s should be set to an empty string.
The problem I am having is that I am using try/catch block to try to parse as an int but then it breaks out of execution completely.
I hope this makes sense and that someone can help.
Thanks!

this is because your code is probably inside one giant try catch block, what you need to do is have small ones in places where you do the parsing.
post code and i can show you how to modify it

Custom program for Dynamic Actions

Iam using BDCs for Actions and Org.Assignment infotypes. The dynamic actions are planned to be carried out by using separate function modules.
My query is, On the plausibility check conditions lots of structures are referred (eg: PSPAR,RP50D etc). How do i perform this condition check in the custom program (for dynamic actions) as these structures do not have any data?
Thanks
Message was edited by: SShenoy

1. PSAVE-FIELDNAME will use the old values in the FIELD. It will be used in cases when we have to do plausibility checks on the basis of new as well as old value, eg, we want to use dynamic action for employees whose status changes from 'inactive' to 'active'
2. Sequence no represents sequence no. If for a particular Infotype and FCode, we have to specify which step has to be performed first. Sequence no tells the system exactly this thing.

3.2 to 4.1 Upgrade - Error Handling for Unavailable Database Links

Hi,
I'm having a 3.2 -> 4.1 upgrade issue related to error handling for failed database links.
I have a conditional Exists button on a page that has a SQL query to linked tables. However, for the 10 minutes every day where the target of the database link is getting a cold backup, the query fails. In the old 3.2 apex I simply got an error inside the region where the button is located but otherwise the page was still visible:
"Invalid exists/not exists condition: ORA-02068: following severe error from MYDBLINK ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist"
However, in apex 4.1.0.00.32 I get the following unhandled error, and clicking "OK" takes me to the edit page when logged in as developer.
i.e., the page can't be run at all while the database links are failing in this one region.
Error Error processing condition.
ORA-12518: TNS:listener could not hand off client connection

General users see this:
Error Error processing condition.
ORA-01034: ORACLE not available ORA-02063: preceding line from MYDBLINK
clicking "OK" takes user to another page, not sure how apex decides which, but not a concern at the moment.
I've done a search and read the page http://www.inside-oracle-apex.com/apex-4-1-error-handling-improvements-part-1/ but the new apex error handling isn't clear to me, and I don't know if the apex_error_handling_example provided on that page would be applicable to this situation.

Thanks Patrick.

      select alert_1 from v_localview ) loop
        return true;
    end loop;
    return false;
exception when others then
    sys.htp.p('Invalid exists/not exists condition: ' || sys.htf.escape_sc(sqlerrm));
    return false;
end;As a view is simply a query I'm surprised this should make any difference but it now looks similar to the 3.2 error, inside the region, when the linked database gets its morning cold backup, and this is fine:
Invalid exists/not exists condition: ORA-12518: TNS:listener could not hand off client connection

How to display an error message in Dynamic Actions

Dear Team:
Scenario as below:
Whenever the user creates Contract Elements Record, the begin date should be checked with the hire date in 0041 - Date specifications infotype (Date type) and Date of hire. If this is not equal to, then record should be rejected with an error message. Please let me know how do I write the lines in table V_T588M for infotype 0016.

OSB 10gR3 Error handling and reporting action approach

My use case:
Simple Proxy service routes to an external web service created as Business service in OSB
Whenever there is transport error/soap fault from the external web service, that error needs to be reported along with the original request received by the proxy service.
What I have tried so far?
Created a error handler/stage in the route node of my proxy service. Within that stage, added a report action to report $body which contains the error received from the external service. I created a report index key/value to report for this request, I used a specific element in the body of the original request sent to the proxy service.
Within the route error handling stage, I realized that $body which had my original request to the proxy service lost its content and replaced by the fault from external WS. So I made a copy of $body in my request pipeline and tried to use an element from that copy to index my failed request. But the copied variable always seem to be empty within the error handling stage.
So, my questions to the experts,
1)What variables are visible within the error handling stage/scope?
2)What is the best way(less overhead) to preserve my original request as $body context variable is already changed with fault by the time error handler is invoked? Remember I wanted to report the original request only incase of error, for success cases I don't care/I don't want to un-necessarily add an overhead of copying to a vairbale.
3)Is there another proper way to simply report the original request received by proxy and fault received from external service for a given key in the request, say orderId
Sample proxy request:
<MyData>
<OrderId>123</OrderId>
</MyData>

1)What variables are visible within the error handling stage/scope? $fault - http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1051816
$body - http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1103311
2)What is the best way(less overhead) to preserve my original request as $body context variable is already changed with fault by the time error handler is invoked? Remember I wanted to report the original request only incase of error, for success cases I don't care/I don't want to un-necessarily add an overhead of copying to a variable.Can you print $body and $fault variables in your error handler?. Are they different ? What I'm suspecting is the back-end webservice is faulting (returning soap-fault and http response =5xx). There is no other way I can think of than copying the contents of $body to a separate variable.
Thanks

Theme 11, live scope for dynamic action not working in IE

Hello all,
I use theme 11, and I have a dynamic action on page 0 that fixes a region width, because it is too long to match the page width. I set the Event Scope to "live" because the region is a report and it has many rows and pagination is needed. When I have to go to page 16-30 from 1-15 and if there is a record which is longer than the current 15, page is partially refreshed and the width is changed, but that works for Mozilla and Chrome. In IE the dynamic action from page 0 is not triggered, in spite of the live event scope and I don't know why. Is there a way I can fix that problem?
Thanks in advance!

Hi Ivan,
Thanks for the information, this is indeed an interesting case. I'm assuming you have 'Enable Partial Page Refresh' in the report attributes set to 'Yes'. Please let me know if this is not the case.
I don't think an event of 'Page Load' with a scope of 'live' is correct. The 'live' event is a way of saying, attach some behaviour to something on a page (eg a delete icon in a report row is clicked), and keep that behaviour 'alive' even if that part of the page is updated (eg the report paginates with PPR to the next set or results, and clicking on the delete icon in the report still works). However here, when the event is page load, I don't think specifying 'live' will do what you want.
What I think you're really interested in is indeed when the page first loads, but then when the report is refreshed via PPR. Therefore, I would try the following:
1) Change the dynamic action event to 'After Refresh'.
2) Select the report region from the 'When > Selection' attributes (ensuring your report template contains a id="REGION_STATIC_ID" attribute, otherwise the DA won't work).
3) In your 'Actions', ensure the 'Fire on Page Load' checkbox is checked.
So this says do the action when the page loads, then always after the report is refreshed via PPR. This will fire after pagination, sorting or a dynamic action refresh.
Interestingly (at least in my mind!), you can actually set the event scope back to 'bind' here. This is because as part of the DA framework, we purposefully attach the event handlers for report handling to an element that is not updated during PPR for pagination or sorting, it's higher up in the DOM tree. This gives slightly better performance than having to use 'live', which is more expensive computationally and yet still keeps the registered behaviours.
Also something else which may help, you can check if the DA is firing when expected by using a JavaScript console (eg in Chrome native Developer tools, Firebug with Firefox), with application debugging enabled (Application Properties) and switched on (via developer toolbar). Load the JS console, and you'll be able to see when the DA fires.
As far as the actual IE specific logic goes, I haven't looked into that too much yet, because I felt it was more important to get the DA firing correctly first, then see where we're at.
Regards,
Anthony.

Error Handling for DSO

Hi all,
Is it not possible to give error handling options for DSO in Delta loads?
I have created a delta infopackage to load data from Order Line Item (2LIS_11_VAITM) into a DSO.
But the error handling gives only option 'No Update ,No reporting'.
I want to give the option 'Valid Records update, reporting possible (request green)' option.
Please let me know whether any setting needs to be done to make this option available.
Thanks in advance.

Check this help - self explanatory - trying checking F1 thats very informative and self explantory most of the times
Switched off
If an error occurs, the error is reported as a package error in the DTP monitor. The error is not assigned to the data record. The cross-reference tables for determining the data record numbers are not built; this results in faster processing.
The incorrect records are not written to the error stack since the request is terminated and has to be updated again in its entirety.
No update, no reporting (default)
If errors occur, the system terminates the update of the entire data package. The request is not released for reporting. The incorrect record is highlighted so that the error can be assigned to the data record.
The incorrect records are not written to the error stack since the request is terminated and has to be updated again in its entirety.
Update valid records, no reporting (request red)
This option allows you to update valid data. This data is only released for reporting after the administrator checks the incorrect records that are not updated and manually releases the request (by a QM action, that is, setting the overall status on the Status tab page in the monitor).
The incorrect records are written to a separate error stack in which the records are edited and can be updated manually using an error DTP.
Update valid records, reporting possible
Valid records can be reported immediately. Automatic follow-up actions, such as adjusting the aggregates, are also carried out.

Error handling for importing a file

Hi, I have only been doing java for 1 semester, and have got terribly stuck on my final assg. I have to import a txt file, and catch any exceptions. I know I am not using the correct method to read the file, but am not sure what the alternatives are. I am getting a compile time..illegal character msg for my Mydata.txt file. Here is my code.
PS I do have a CatalogueItem class and a bit more to the main class, I have not attached it as I do not want this to be too long.
/The program reads 10 sets of catalogue data from the Mydata.txt file
//it prompts the user to use one of the 5 menu options displayed on the screen
//depending on which option is selected the program displays the data
//back on the screen.
import java.awt.*;
import java.lang.*;
import java .io.*;
import java.util.StringTokenizer;
import java.text.NumberFormat;
import java.util.Locale;
//set up a class to call on the constructors from the catalogueitem class
public class Myassg5
     private static final int MAX = 10; //sets the length to 10(for most exp products)
     private static CatalogueItem[] prodlist; //sets array for product list
     NumberFormat cash = NumberFormat.getCurrencyInstance(new Locale("en","AU"));
     public static void main(String[] args) throws IOException
     CatalogueItem prodlist = new CatalogueItem[10];//sets the length to 10
     {//create Buffered FileStream and initialise to zero
     //use bufferedReader to read in data my Mydata.txt file.
     BufferedReader inFile = null;
     BufferedReader inFile = new BufferedReader(new FileReader(C:\Mydata.txt);
     //print a msg stating the file is loading
     System.out.println("Loading file data from Mydata.txt...10 item(s) OK");
     //initialise the array elments to zero
     for( int a = 0; a < prodlist.length; a++)
     prodlist[a] = 0;
     //if incorrect command lines were passed in display
     //usage msg and quit program
     if(prodlist.length != 1)
          System.out.println("Usage: java assg <Mydata.txt>");
          System.exit(0);
     try
          inFile = new BufferedReader(new FileReader(args[0]));
     //display the error and quit if the file is not found
     catch(FileNotFoundException e)
          System.err.println("File not found--program will terminate");
          System.exit(1);
     //display error msg and quit if there is a problem
     //when opening the file
     catch(IOException e)
          System.err.println("Error opening file--program will terminate")
          System.exit(1);
     //repeat this error handling process as often as neccessary
     boolean go = true;
     while (go)
     //get a line of data from the file
     boolean valid = false;
     CatalogueItem prodlist =-1;
     while(!valid)
     //read the line of text from the file
     String temp = null;
     try
          temp = inFile.readLine();
     //display error msg and quit if there is a problem
     //reading from the file
     catch (IOException e)
          System.err.println("error reading from the file--program will terminate");
     System.exit(1);
     //if the string is null the EOF has been reached
     if(temp ==null)
          valid = true;
          go = false;
     //close the file stream
     try
          inFile.close();
     //display error if there was a problem closing the file
     catch (IOException e)
          System.err.println("error closing data file")


I think the problem is the "\M" in "C:\Mydata.txt". It is trying to make that into an escape character. Use "C:\\Mydata.txt" or "C:/Mydata.txt" instead.
The logic here is odd. You open a BufferedReader for Mydata.txt, then you trash it without closing it and create another BufferedReader for whatever command line argument the user passes in. Which reader do you want to keep?

Error handling for distributed cache synchronization

Hello,
Can somebody explain to me how the error handling works for the distributed cache synchronization ?
Say I have four nodes of a weblogic cluster and 4 different sessions on each one of those nodes.
On Node A an update happens on object B. This update is going to be propogated to all the other nodes B, C, D. But for some reason the connection between node A and node B is lost.
In the following xml
<cache-synchronization-manager>
<clustering-service>...</clustering-service>
<should-remove-connection-on-error>true</should-remove-connection-on-error>
If I set this to true does this mean that the Toplink will stop sending updates from node A to node B ? I presume all of this is transparent. In order to handle any errors I do not have to write any code to capture this kind of error .
Is that correct ?
Aswin.

This "should-remove-connection-on-error" option mainly applies to RMI or RMI_IIOP cache synchronization. If you use JMS for cache synchronization, then connectivity and error handling is provided by the JMS service.
For RMI, when this is set to true (which is the default) if a communication exception occurs in sending the cache synchronization to a server, that server will be removed and no longer synchronized with. The assumption is that the server has gone down, and when it comes back up it will rejoin the cluster and reconnect to this server and resume synchronization. Since it will have an empty cache when it starts back up, it will not have missed anything.
You do not have to perform any error handling, however if you wish to handle cache synchronization errors you can use a TopLink Session ExceptionHandler. Any cache synchronization errors will be sent to the session's exception handler and allow it to handle the error or be notified of the error. Any errors will also be logged to the TopLink session's log.
