Fault/Exception handling in 11g

Does anyone have any best practices or approaches they can share on how to deal with faults (at the BPMN process level, not human tasks) in 11g?
I'm referring mostly to system faults, not business faults.

Maybe I should have looked at the new schema first.... : }
It's now reference:
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicyBindings version="2.0.1" xmlns="http://schemas.oracle.com/bpel/faultpolicy">
*<reference faultPolicy="GetDateFaultPolicy">*
<name>GetDateService</name>
*</reference>*
</faultPolicyBindings>

UTL file exception handling oracle 11g

We use oracle 11g
We use UTL file and exception handling in many place. Thanks in advance.
We have many utl program and we are writing same exception handling code ,copy and paste .
It is possible to create new UTL exception procedure and call it.
I am not sure how to write generic UTL exception procedure and reuse the same.
I am learning oracle etl files method.
Please advise.
sample program 1 :
DECLARE
fileHandler UTL_FILE.FILE_TYPE;
BEGIN
fileHandler := UTL_FILE.FOPEN('test_dir', 'test_file.txt', 'W');
UTL_FILE.PUTF(fileHandler, 'Writing TO a file\n');
UTL_FILE.FCLOSE(fileHandler);
EXCEPTION
when utl_file.invalid_path then
raise_application_error(-20001,
'INVALID_PATH: File location or filename was invalid.');
when utl_file.invalid_mode then
raise_application_error(-20002,
'INVALID_MODE: The open_mode parameter in FOPEN was invalid.');
when utl_file.invalid_filehandle then
raise_application_error(-20002,
'INVALID_FILEHANDLE: The file handle was invalid.');
when utl_file.invalid_operation then
raise_application_error(-20003,
'INVALID_OPERATION: The file could not be opened or operated on as requested.');
when utl_file.read_error then
raise_application_error(-20004,
'READ_ERROR: An operating system error occurred during the read operation.');
when utl_file.write_error then
raise_application_error(-20005,
'WRITE_ERROR: An operating system error occurred during the write operation.');
when utl_file.internal_error then
raise_application_error(-20006,
'INTERNAL_ERROR: An unspecified error in PL/SQL.');
when utl_file.invalid_filename then
raise_application_error(-20010, 'The filename parameter is invalid.');
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(fileHandler ) THEN
UTL_FILE.FCLOSE (fileHandler );
END IF;
RAISE;
END;
How to write generic procedure of utl exception handling ?
please advise.
create or replace procedure sp_utl_exception

Very poor implementation.
a) Absolutely no need for that exception handler in there. It should be removed.
b) As it's a procedure for logging exceptions relating to UTL_FILE, it would seem error prone to be logging the errors with UTL_FILE. For example, what is it supposed to do if the exception is raised because of lack of disk space in those file locations? How is it going to write out the exception with the disk full? Also, if the exception handler is used by multiple processes, then only 1 process at a time can access the log file to write it's exceptions, so it doesn't scale well. Better logging is done by having an autonomous transaction procedure that writes log/trace messages to dedicated table(s). That also means that the logs etc. can be viewed, as appropriate, from any client using SQL (either manually or through a application written to view logs etc.), rather than requiring physical/remote access to the server o/s to go and view the contents of the file, which in itself could lock the file and prevent any process from writing further logs whilst it's being used.

Exception HAndling B2B 11g .AQ Integration

Trying to catch the B2B exception for 850 and send it to SOA. I have used AQ integration for B2B.Please tell me how to implement this in soa

All the B2B errors/exceptions get enqueued to IP_IN_QUEUE (by default) in a proper format (ipException.xsd defines the structure) and has recipient name b2berroruser. You may create your own process for dequeing those exception messages and perform error handling.
You may also configure a custom error queue (JMS) if you do not want to use IP_IN_QUEUE (which is an AQ). For all details, you may refer the user guide -

Best Practice for Implementing Exception Handling in BPEL

Hi All,
what is the best practice and the approach to follow Exception Handling in BPEL.
1) Do we need to implement Exception Handling in BPEL as we do in Java, means
     method 3 throws error to method 2 (if any) and
     method 2 throws error to method 1 (if any) and
     finally method 1 throws error to the main Class.
If we replicate the above scenario to BPEL
In BPEL main Scope have Custom Fault, Catch ALL
     Each Invoke is surrounded by a Scope Activity with Remote Fault, Binding Fault & Custom Fault
and follow the paradigm of Java, assuming we have Inner Scopes
     [ OR ]
2) In BPEL main Scope have all exceptions defined like
     Remote Fault,
     Binding Fault,
     anyOther System Fault (selectionFailure / forcedTermination),
     Custom Fault (if required) and
     CatchALL
     and also
     each Invoke is surrounded by a Scopes Acitivity with Custom Fault (business fault) exception Handling
I feel 1st one may not be a good practice, may be i am wrong...
Any Suggestions from experts.
Thanks in Advance
anvv sharma

Hi-
In you can create different scope and use catch branch to catch binding, remote, custom faults, business faults etc. If an error happens in a scope it will not move to the next scope( eg: you have 3 scope, error occured in 2nd scope then it will not propogate to the 3rd scope. One thing to be noticed here is your transaction in the 1st scope doesnt gets commited when an error happens in 2d scope).
You can have a catch all to catch error which are not being caught at catch level. So if any error happens which is not defined in catch block then then it will be caught in catch all branch.

Exception Handling In BPEL By using Catch Blocks or Fault Policies Or Both

I have a confusion regarding
Exception handling :
When Should i go for 1)Catch Block (Remote , or binding ) in bpel for exception handling .
2)Fault Policy , Fault binding.xml
Currently iam using catch blocks , but even fault policy is good , but can i use both...
Currently in My bpel ,when any error occurs i have to send a error notification by Email .
Currently i have exposed the email service which shuts emails and write a file with errored Message.
Hence if any error i will catch i in a parent BPEL, i will just invoke the above email, service .
So anybody can help me by giving the suggestion how to go for the best approach

Currently in My bpel ,when any error occurs i have to send a error notification by Email .
Currently i have exposed the email service which shuts emails and write a file with errored Message.Seeing your use case I will suggest you to use fault handling framework (fault policy). Fault handling framework should be used where you need generic error handling framework which handles all the faults occured in any composite component. Generally BPEL catch block should be used to propagate error info/fault back to the client/to fault handling framework or to consume an error

11g ADF TaskFlow Exception Handling in BPM

Hi Guys
BPM 11g
I have a human task that is implemented as an ADF task flow. I would like to be able to throw an exception from the ADF application and have it handled by the BPM process, does anyone know if this is possible or how I would do that?
At the moment I have an ADF error page - I could return an "error" outcome to the process from that but an error is an error and it feels right to show that in the process instead of a normal outcome.
anyone else worked through this?
cheers,
Steve

Exception handling with fault message type not working

Hi,
I have a sync proxy to proxy scenario and I have created a fault MT and specified in the outbound and Inbound service interface...
*In Inbound proxy I have the following code--*......
RAISE EXCEPTION TYPE z_cx_test_fault
EXPORTING
standard = l_standard_data.
In the sender side abap code which calls the outbound proxy I have the follwing code -
CATCH cx_ai_system_fault INTO lo_cx_ai_system_fault.
txt = lo_cx_ai_system_fault->get_text( ).
WRITE txt.
CATCH z_cx_test_fault INTO lo_cx_test_fault.
txt = lo_cx_standard_message_fault->get_text( ).
WRITE txt.
CATCH cx_ai_application_fault INTO lo_cx_ai_application_fault.
txt = lo_cx_ai_application_fault->get_text( ).
WRITE txt.
when i test the inbound proxy separately I get the custom fault message properly...
however when i run the proxy to proxy sync scenario and the custom exceptionz_cx_test_fault is raised inside the receiver proxy .......control goes to CATCH cx_ai_application_fault and not CATCH z_cx_test_fault .
I understand that cx_ai_application_fault is the super class of all the exception class but why does control go to its exception handling when a custom exception is raised...

Hi
I tried changing the sequence also but it did not work...
I can see an appropriate response coming from the receiver in SXMB_MONI of PI...this response has the "fault response "
"fault detail" data that I want.....however when the control goes to the sender why does it go to CATCH CX_AI_APPLICATION_FAULT and not not my CATCH z_cx_test_fault .
My observation - If I change the scenario to SOAP to Proxy sync..then the sender SOAP client gets the appropriate custom fault message back.

Mediator Exception Handling without fault policies

Hi,
Could somebody help me on defining exception handling to MEDIATOR component?
Is there is a way where we can do this without using the fault policies?
Thanks,
SV.

Business faults are application-specific and are explicitly defined in the service WSDL file. You can handle business faults by defining the fault handlers in Oracle JDeveloper at design time. System faults occur because of some problem in the underlying system such as a network not being available. Oracle Mediator provides fault policy-based error handling for system faults.http://docs.oracle.com/cd/E21764_01/integration.1111/e10224/med_faulthandling.htm

Integration Process exception handling & alerts, Java

Hello,
I would like to enhance my basic scenarios fool proof and with as much Java as possible.
I have set up several asynchronous and synchronous File to SOAP transfers between systems A and B
using PI70 including my own Java mapping classes and PI's AF_Modules beans. They work just fine.
I have not designed my own Integration Processes yet, so execution is based on channel settings and availability timing.
I have learned this aproach may be exposed to general faults resulting manual monitoring and repairing.
For example server problems at receiver side can result data losses as sender channel just keeps removing source
files like normally, as the process would be better to just stop right there and alert or something.
My question is, is the "Enterprise services Builders" Integration Process & Graphical definition screen the one and only tool to
customize whole process exception handling and alerts in PI, and Java is not an option?
Appreciate your advice on this.
Kind regards m

>>I have learned this aproach may be exposed to general faults resulting manual monitoring and repairing.

If you are looking to handle this particular scenario, then we have the alert mechanism and CCMS monitoring. There you will come to know whether the end system down or not.
Also in addition to this you can write your own java (in message mapping, as modules, java mapping) /abap code (as abap mapping, user exit in standard functions etc) for providing more details in error scenarios. But you need to validate whether the maintenance/development cost for the code is justified in your scenarios

Exception handling in CE Visual Composer 7.1

Hi,
I have modeled a CAF Business Object and a custom Find operation which looks for a custom key. After that, I have exposed that operation as Web service and consumed it in Visual Composer. It is working perfectly as long as the search key exists in the Business Object backend table. When an arbitrart search term e.g. 1234 which does not exist is given, an error message is displayed and the program logic is halted.
Error occured while executing the service: Error in connection: Could not execute Web service, consult your administrator
My requirement is that, is it possible for me to display a custom message such as "The ID does not exist. Please enter a valid ID".
Besides, is it possbile to bypass this service call if it is not working? In my scenario, this service is actually used to search for any existing data for a selected Customer. If there is no data, the user can proceed with a new definition. So, the above mentioned exception blocks the program flow and the user is not able to continue.
Thanks in advance for any suggestions or ideas.
Regards,
Joon Meng

I am not aware exception handling features of VC but instead of raising SOAP Fault you can also transfer log message which is user friendly to display.
Another thing, instead of throwing exeption handle it inside try block so that program do not halt abruptly but gracefully. It is always possible to bypass existing service call like you said if output of service is not input of another.
In other word do not map output directly but on the "Next" event of button which enable you to goto next screen to work.

Step repeated in Exception branch requires exception handler, why?

I have a BPM Integration process with a sync send step calling a RFC. Any system errors and application errors are handled by an exception branch where I send an alert as then re-do the send step (so that it will fail but allow me to restart from that point after fixing the issue). The problem I am having is that in this send step, since it is mandatory to have an exception handler for application errors (defined fault message RFC.Exception), what do I enter for exception handler in this send step which is itself in an exception branch? I do not want to handle the exception this second time since I want this step to fail and process stops here to be able to restart manually later.

Hi,
I am not sure, how you will restart the step manually? Because once there is an error in the sync send, the message will turn to "Cancelled" status. You cannot restart this message.
Now, for the second send step in the exception block you will not be able to choose the same exception block in the exception handler field. But for some reason if this send also fails then you cannot restart the process manually - same reason i mentioned above. It will fail as you intended it to do so.

Task flow exception handler

Hi all,
I'm trying to specify a method activity as an exception handler in the adfc-config. The problem is if I specify a view activity or a bounded task flow as the exception handler then it works fine, but if the exception handler is a method activity then it is not recognized. What could be the cause?. I need to execute a method when an exception occurs.
Version: 11.1.2.0
Edited by: NewBee on Apr 23, 2013 10:37 AM

Hi,
there should not be a problem with this and I recently did the same with JDeveloper 11g R2 (not sure which version of JDeveloper you use because you did not share this information). I assume you just marked the method activity as an exception handler without any other configuration? If so then set a break point to the managed bean method that you access from the method activity to see if it actually stops there. Also note that not all exceptions are handled by the controller exception handler. E.g an exception during render response phase (typically an exception in a managed bean) is not handled by the controller. Also you need to avoid the managed bean that handles the exception to itself throw one. This however you will see when debugging the bean.

Flow Activity Exception Handling Problem

Hi,
I am using Flow Activity in my Bpel Process, i am getting some exception in one of flow, but other flows are working fine. Even i have included Catch block for other flow still i am getting fault response.
Please suggest me how to do exception handling in Flow Activity.
Thanks in advance.

Hi,
just restructure your BPEL process. The 'Flow' activity contains several 'Sequence' activities. Simply ... put a 'Scope' activity inside of each 'Sequence' activity. Then put another 'Sequence' activity inside of each 'Scope' activity ... and put there required logic/activities.
After that you can create fault handling on these 'Scope' activities. In this way you can handle faults in each flow-sequence.

Martin

Hi,
Pretty much. However, you got the event part wrong, which is mostly my fault here. First, let put down some general JSF facts about event handling.
1. http://java.sun.com/javaee/5/docs/api/javax/faces/component/UIComponent.html#queueEvent(javax.faces.event.FacesEvent)
2. So, basically, queuing an event on a component means queuing it on its parent until you reach the UIViewRoot that will really actually queue it. That strategy allows iterating components to intercept event queued on their children to record the row index as well so that the data model can be synchronized correctly during the broadcast phase (see http://java.sun.com/javaee/5/docs/api/javax/faces/component/UIData.html#queueEvent(javax.faces.event.FacesEvent) and http://java.sun.com/javaee/5/docs/api/javax/faces/component/UIData.html#broadcast(javax.faces.event.FacesEvent))
3. Exceptions that aren't handled by the exception handler are thrown during broadcast or various process* methods.
So, the catch component must leverage these facts to intercept events queued on its children (by overriding queueEvent method) wrapping the original event in a custom on that flag the catch component itself as the source of the event. The result will be that the broadcast method of the catch component will be called to handle the event. The broadcast method must then unwrap the event (to get the original event), gets the original source, then call originalSource.broadcast(originalEvent) within a try-catch block.
Does it make any more sense put that way? Note that it's an obscure part of JSF so I cannot make it incredibly simple either.

~ Simon
