OdiInvokeWebService - Fault Handling
Hi,
I am using ODI version 11.1.1.5.0 which support secure service call using OdiInvokeWebService tool. I am able to get the response into a file for a successful service invocation. But in case of any fault the step(OdiInvokeWebService) execution fails and I am able to see the fault message in session execution log(Under Operator tab-> Session List).
As per my requirement the service call can return various types of fault messages and ODI has to route to different step based on the fault message.
Can you please suggest me how to do fault handling (in simple, reading the fault message)?
Thanks,
Sisir
Hi Sisir,
In short, you should be able to use the substitution method odiRef.getPrevStepLog("MESSAGE") to get the error message. From here, though, you'll probably need to figure the best way to evaluate the variable and make a determination on how to proceed.
I would use Java code to parse the error message for the information about the error. You can then go from there with your need to execute different steps based on the error type.
Hope this helps.
Enjoy!

What are the different approaches to do Fault Handling?
for uplodig data to non sap we have 2 methodes
i) if u know bapi u will use lasm
2) bdc
but u mentioned so many records isthere
best thing is u will uplode all record sto al11 using XI interface
then u have to write bdc / lsmw program

Clarification needed in the Fault Handling Framework(Error Hospital)
Hi,
I need some clarification on Fault Handling Framework...
Scenario:
My BPEL Process is Asynchronous.(10.1.3.3.1) and I tryed to invoke the another BPEL Process( which is used to select the Fname from the table using DB Adapter) . In the Main BPEL Process I have the Fault handling Framework and I done necessary changes in the bpel.xml. This is successfully working for Invoke Activity when ever an Remote or Binding Fault occurs in the Sub-BPEL Process and this Fault is send to Fault-Policy.xml in the server(bpel/domains/default/config/fault-Policy) and works accordingly to the action mentioned in the policy xml....( I have also made changes in the fault-bindings.xml ).
How ever this Framework is working fine for every actions.
Need Clarification:
1) Only the Binding and Remote faults will work for the Fault handling Framework.
2) can we use User defined faults (Buissness Faults,,,) for this........because I used the User defined faults to invoke the fault-policy.xml and it won't works....
3)Only Invoke Activity can be handled for this Framework or any Other Activity........
4)How to handle other Activity in the Fault-policy.xml...
5)Any difference for Asynchronous or Synchronous in this Fault Handling Framework.......
I also referred the Oracle SOA Suite New Feauters PDF .......
Can any one send me the related documents and try to help me on this.
Please help me on this.......
Thanks,
Ashok.Hi Chintan,
You are saying that Custom faults are also supported for fault-Policy.xml.
I can't understand that 2nd answer you said. can you please explain how to use the Custom faults in the FaultHandlingFramework..
My Scenario:
I have 2 BPEL Process, BPEL1 will invoke the BPEL2 and if any remote fault or binding faults occurs in the BPEL 2 its returning the same fault to BPEL1 and here I am using FaulthandlingFramework , this fault send to fault-policy.xml and necessary action is took place succesfuly...(like retry, human intervention.....)
But when I throw some CustomFaults(userdefinedFaults)in the BPEL2 , its returning as a remotefault to BPEL1. I don't know how to use the customFaults in the Fault handling framework.......
Can you explain me in detail how to use custom faults in faulthandling framework...............
Send me some related documents for this..... -
Fault Handling in BPEL process
hi
We have to develop an application which involves several BPEL processes and proxy service(OSB) and JMS queue etc.
What is the difference between Fault Management Framework in SOA11g and normal fault handling(using catch and throw activities)?
which one we should prefer for fault handling in our application n why?
Plz help thanks in advance.Hi-
In Normal Fault handling process, you will be able to catch the faluts only but in Fault Management Framework if a fault occurs the framework catches the fault and performs a user-specified action defined in a fault policy file associated with the activity. You can also have a human intervention prescribed in it, where you perform recovery actions from Enterprise Manager.
Pls go throgh the below post for detailed description

Edited by: user5108636 on 18/06/2012 00:20By the way, I managed to break through a little further. Now I am past this fault policy error. However, the java fault handler class is giving ClassNotFoundException. The way I added the java file (test.EmailFaultHandler) through JDeveloper in the composite project (Right click --> New ---> Java file). How do I add this to the classpath. I thought it automatically gets added to the SOA composite project classpath.
Please suggest.

Hi,
This is regarding SOAP fault handling in OSB11g.
i am expecting that whenever OSB proxy service recieves a fault response the flow should move to service error handler if any. But its not happening.
We tested our service with SOA Test stubs and SOAP UI mock services. When SOA test stub send fault response OSB considering it as normal response. But when the same fault is sent by SOAP UI mock service OSB is considering it as fault and going to service error handler.
Now the same is happening when we replaced the service provider with one of the .NET service. The fault response is in SOAP 1.1 structure.
Please let me whats the difference or any setting or HTTP response code we need to look at.
Thanks & Regards
SivaHi Anuj,
I am using the same fault structure which is working in Soap UI mock service. Still its not working in Soa test stub. And now facing the same issue when fault comes from .NET based service provider.
Will verify once to see whats the response code thats being sent.
Thanks

Hi,
We have a DBAdpater to retrieve the data and a mediator to invoke the DBAdapter. In cases like No Records we want to create a soap fault. So we implemented Mediator Java callout and overriden postRouting() to read the response message and create a soapfault.
[ we referred to blog http://technology.amis.nl/blog/6669/soa-suite-11g-introducing-mediator-java-callouts-for-debug-audit-and]
but when we tried creating SOAPFault and add it to the response message, while execution , the response message is being parsed and seeing the fault it is throwing the exception below:
java.lang.Exception: oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException:

I found that if exception from mediator is not handled, then the exception is throw as system fault as shown above.
So we tried implementing external fault handling - by creating fault-policies.xml and fault-bindings.xml and a java callout.
fault-bindings.xml
<?xml version=”1.0" encoding=”UTF-8"?>
<faultPolicyBindings version=”2.0.1" xmlns=”http://schemas.oracle.com/bpel/faultpolicy”>
<composite faultPolicy=”SOM_ServiceFaults”/>

</javaAction>
</Action>
</Actions>
</faultPolicy>
</faultPolicies>
But still getting the error.Appreciate any help on this.
Thanks in Advance,
SubhashiniNot exactly but doing it the other way around by copying the fault msg to output variable and check flag for the response in my initial requester process then throw fault accordingly.. didnt have much time as it was holding back my other deliverables
Thanks a lot for your time -
Fault handling in DIServer Interact
Good Day Mentors,
I'm currently testing out how the DIServer works.
Now, I am testing Fault handling with the DI Server,
and would want to know if there is a way to get multiple Errors from an DI Server Interact call.
My test scenario was adding 2 Sales Orders into SAP via DI Server using the Interact Call(Not BatchInteract).
The actual SOAP call sent , with comments, is as below:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">

</DocumentLine>
</DocumentLines>
</Document>
</dis:Add>
</env:Body>
</env:Envelope>
I commented the parts that should throw errors, which are the non existent ItemCode and AccountCode in 2 separate Sales Orders.
I was hoping to get a Fault Response from the DIServer which tells me that there are two error from 2 different Documents.
Basically, 2 separate error messages for the 1st Sales order(non existent Item Code) and 2nd Sales Order (Non Existent Account Code).
But the Fault Response I got from the DIServer was this:
<?xml version="1.0" ?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
<env:Body>
<env:Fault>
<env:Code>
<env:Value>env:Receiver</env:Value>
<env:Subcode>
<env:Value>-1</env:Value>
</env:Subcode>
</env:Code>
<env:Reason>
<env:Text xml:lang="en">Error in SOAP command 'Add'</env:Text>
</env:Reason>
<env:Detail>
<Command>Add</Command>
<SessionID>5659CCC6-2E15-4664-BFA2-4E6A3BDD3E35</SessionID>
</env:Detail>
</env:Fault>
</env:Body>
</env:Envelope>
The fault response only tells me that there is an error, but nothing specific to the documents. Just something specific to the actual SOAP call.
If I something is not clear, please do clarify with me.
I'm using SAP B1 9.0 PL05.
Thanks in advance!
SeanHi Sean,
I don't think there is such a feature available. This is standard behaviour in SBO - same for UI and DI API. The first problem/error found will abort the action and message is shown and in this case it is one action ( interact).

Hi,
I am new to this bpel.I want to ask a basic question regarding bpel fault handling management frmawork ..
My BPELProcess1 has just a throw activity with receive and reply activity.and I throw a bindingfault there.
Then I added two xml files(fault-policies and fault-binding) where composite.xml resides and added property elment in the composite.xml.
So,I think here fault policy and binding will work fine .But when I execute it I don't find any recovery option in em console.
fault-binding.xml ->
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicyBindings version="2.0.1"
xmlns="http://schemas.oracle.com/bpel/faultpolicy"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<component faultPolicy="myFaultHandling">
<name>BPELProcess1</name>
</component>
</faultPolicyBindings>
and fault-policies.xml file looks like
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicies xmlns="http://schemas.oracle.com/bpel/faultpolicy">
<faultPolicy version="2.0.1" id="mylFaultHandling"

</condition>
</faultName>
</Conditions>
<Actions>
<Action id="ora-human-intervention">

</faultPolicy>
</faultPolicies>
and added this to the composite.xml
<property name="oracle.composite.faultPolicyFile">fault-policies.xml</property>
<property name="oracle.composite.faultBindingFile">fault-bindings.xml</property>
My question is
1.Do I need to add a catch/catchAll block in bpel file ?and I want to know is it only a substitute mechanism to avoid catch/catchAll blok..
2>Is there any way that I can catch the all project fault in a single framework by configuring em console rather than adding catch block or policy xml in each project ?

For define the fault policies at the global level for all you project composites...u share the fault-policies.xml,fault-bindings.xml from mds and apply them to each composite. -
Fault handling in osb using publish
Hi all,
i am new to OSB, every thing is working fine. i will explain how we design the basically we have inbound and outbound. call inbound as 'aaaa' and outbound as "bbbb". we have created the proxy and BS which will communicate with EBS, BAM and B2B. i have created BS for all the three. from PS i used 2 assign and 1 publish activity. we are publishing directly to BS correspondingly. since i am not using any route activity i could not get the error back or any invocation error messages. can any one tell how to capture the error and place it into BAM report. we can transform data to BAM we just need to get the details about the fault handling in OSB.
thanks ----Hi prabu,
thanks for your response.
As we have the discussion on this issue for quit a long time. i have configure the error handler in the proxy services when my EBS throws the error. error handler come active and some data is published to bam. here i got the problem is that, the PO which we are sending is one way or fire and forget when using Publish action. when the PO hit the EBS, i.e. when error message is passed through the test XML, error is occuring and and reporting to bam with some null values. i need to capture the data processed at that transaction. is it possible to capture the data in error handler which is errored out in message flow of PS.
can you please help me
thanks--

Fault handling in 11g - fault-bindings.xml for a partnerLink
I'm using 11g and I'm trying to use the fault handling framework for a specific partner link. In fault-bindings.xml I have:

<faultPolicyBindings version="2.0.1" xmlns="http://schemas.oracle.com/bpel/faultpolicy">
<partnerLink faultPolicy="GetDateFaultPolicy">

I have a partner link named GetDateService in the bpel that I'd like to defin a policy for, but when I try to compile, I get:
Warning(3,58): Schema validation failed for fault-bindings.xml<Line 3, Column 58>: XML-24534: (Error) Element 'partnerLink' not expected.
Does the framework still allow partnerlinks granularity, it says it does in the docs?
ThanksMaybe I should have looked at the new schema first.... : }
It's now reference:

11g: Help regarding fault handling framework
I am trying to implement a POC demonstrating the fault handling framework using fault policies. I am trying to handle remote and business faults. These faults are being thrown explicitly in the code. But I dont see the framework coming into picture. Here are the fault policies and fault bindings files
The POC does the following
1. If input is R, throws a remote fault.
2. If input is B1, throws a business fault. There is a catch defined for this. But as we also have a policy for this error, we expect the policy overrides the catch
3. If input is B2, throws a business fault. There is no catch defined for this. We expect the policy to handle this.
4. If any other input, we return a string.

<faultPolicyBindings version="2.0.1"
xmlns="http://schemas.oracle.com/bpel/faultpolicy"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<!-- Below listed component names use policy ComponentFaults -->
<component faultPolicy="ComponentFaults">
<name>BPEL</name>
</component>
</faultPolicyBindings>I created another bpel in the same composite that calls the original bpel. So now, those errros are supposed to travel to calling bpel.
Fault policies are coming into effect now. So, one part of the problem is solved, that atleast syntax and all is correct, and the fwk does work (!) but another one has opened - why is the fault not getting handled by the fwk if there is a single bpel that is throwing and not catching those faults.
Also, even in this new avatar, fault b1 is getting handled by the catch in BPEL process, while the fault policies are supposed to override any catches in bpel code.
What I was attempting was, throwing the fault in a bpel process and expecting the fault handling fwk to handle it.
It turns out, the framework is not capable of doing this, its only capable of handling faults coming after an invoke activity.
Consulted Oracle Support on this. Their response
The behavior within the single composite you are seeing is correct and is by design. As the documentation states:
http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_faults.htm#BABIGGIB
If a fault occurs during runtime in an invoke activity in a process, the framework catches the fault and performs a user-specified action defined in a fault policy file associated with the activity.
The fault management framework catches all faults (business and runtime) for an invoke activity.
So the above means that unless the fault is thrown in response to an invoke activity the Fault Policy set will not be triggered, which has been confirmed through the test you have uploaded. Please let me know if you have any questions or concerns. -
Hi,
I understand from the document that there are two ways of handling exceptions
1. Creating fault-policies and fault-binding xml files in same directory with composite.xml
2. Placing the two xml file in MDS
How to deploy the fault-policies and fault-bindings xml file to MDS?
Regards,
SundarIn Oracle document for Fault Handling http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_faults.htm#BABIGGIB it is given that fault-policies.xml adn fault-bindings.xml can be placed in same directory of composite.xml or it can be placed in common location.
I take that common location as MDS repository. Can anyone tell me how can i place the two files to MDS repository?
If my understanding is wrong can you please tell me how to achieve the second crieteria?
Regards,

Using Fault handling framework for executing Database procedure
We have a requirement wereby we have API to be executed on Oracle DB which would return a code saying 0 or 1.
I meaning error.
Now with regards to exception handling we require that we receive remote fault we retry for 3 times & if not successful have a email sent out & a human intervention.
This can be easily taken care by having define this in Fault polciy.xml
Another requirement is when the API fails for some reason & we get returncode as 1.Now we would like ot invoke the same policy for this type of error.Although BPEL instance is not failed.But we can throw custom fault.
Now the APi's that we have can be called in 3 ways.
1.In each instance we call API exactly once
2.In each instance we call API in a loop for each record in message.Hence if 10 records are there in message & while executin 7th time it failed then how to handle reminaing records?
3.In each instance we call API only once but submit all 10 reocrds at once.And at same time 7th record fails then whats best way to handle this?
We realy want to use fault handling mechanism because it gives a lot of options of replay rethroew continue...but given the requirement can somebody point out a right way of using fault policy?
ThanksU can archive the records in archive tables once the database adapter polls the data.
