AIA error handling solutions

Hi All,
Could anyone please help me out understanding, what are solutions available from the AIA error handling perspective??
Thannks,
Santosh

If you have used AIA Life Cycle to create your composites, then by default it will have exception handling part associated with it.
On top of it you can use the Work List application to track your exceptions and fault policy management as well.

AIA Error Handling framework

Hi,
We have an AIA implementation where we are not using HWF for error handling. Now we have another project coming up where we would like to leverage this functionality. Was wondering if there is a way to activate HWF for few integrations only not at the server level.

Hi,
You can expose your HWF as a web service and use your new service after invoking this WS.
Is it what you are looking for.

How much it makes sense AIA FP without AIA Error Handlers?

If we decide not to use AIA Error Handling, how much do you rate AIA FP out of 5?
How much it makes sense AIA FP without AIA Err Handler?
And should we go ahead without AIA Error Handling?
Our requirement is litle tricky (can be achieved with some word arounds) to be achieved using AIA EH so we decided to use our own Email handler BPEL to send Error Mails. what challenged we may face going ahead and what things we should keep in mind designing the custom BPEL. Also If we use AIA EH
Please suggest me the best way you think...
We are using SOA Suite 11g
Edited by: panks on Jul 12, 2011 6:18 PM

I even feel the same AIA EH is significant part of AIA.
Here we faced some issues which obviously can be overcame by some changes in prebuilt solution..
1. AIA EH sents Text mail no HTML template I was able to find
2. Role is not role in 11g. it is user :( This is very dis appointing if we want to assign multiple people to a same role. I will have to put them into a dist Mail List. Migration from one instance of Web logic to another for UI messaging(notification channel) is also a challenge. In 10g It was more easy by putting all these in Jazn. I have no Idea same can be achived here in 11g.
3. Error code/Err Msg/Corrective Action: we want customized Error codes and Error messages even when we trigger the CompositeJavaAction from Fault Policy. It was Over riding the values of Fault notification in Composite Java action and Mail is sent. We have no control of customising the Error codes/ Error Message if triggered from Java Action. I will have to write again our own Java Action for this.
I got some where in Doc that some codes and custom texts can be stored in a Resource Class. but again this is overhead to decompile the class file update it and again compile it :) . I have no Idea what led them to put these Texts in a Class :) they have DVM, AIA Config Xref still they used Class for storing hardcoded values which they say are configurable (but how? decompile -> change ->compile??)..

'Structured' error handling and reentrancy

The parentheses in the subject are due to the fact that I'm not using the Structured Error Handler reference library, but have rolled my own to do something similar but in the manner I want it to. I don't actually use the SEH (haven't even got it installed at the moment on this PC) so am not sure exactly how it works under the hood.
I have a reasonably large application with a number of distinct parallel modules (GUI, state module, communication, motion control). The final parallel module is an error handling module. This consists of two queues - one for incoming errors, and one for outgoing actions. Errors are dequeued and their codes checked for their category (critical, warning, ignore or unclassified, for instance) and the appropriate category is returned to a local error handler via the action queue. When an error is passed to a local error handler VI, it enqueues the error to the main handler and waits for a response to that particular error.
This all works nicely, in much the same way the SEH would do. However, with either the SEH or my local error handler method, I find myself wondering how often to place these down and the consequences of doing so. If they're non-reentrant, I imagine I may end up with lots of parallel processes sitting patiently to access the VI as it's blocked by another, causing jitter. If I go pre-allocated clone, I could potentially have many many callers using this function, which strikes me as a bit of a waste of resources. My gut feel is to go with shared-allocation clones, as the vast majority of the time it'll be no error passed through an empty case, and not to place them in absolutely every subVI - just perhaps after a state executes in the state handler, in all the parallel loops of the submodules etc.
Just wondering what anyone else does with their error handling solution, and whether my thoughts make sense.
CLD

Having chatted to my friendly neighbourhood Spiderman Architect, he suggested I should probably just stop being a wimp and just use pre-allocated clones to avoid the jitter and to stop worrying about the resource hit, as you suggest
I'll use the same code on both PC host and RT host, hence the jitter concerns on the RT.
Thanks for the thoughts!

AIA Error Notification Format : HTML Tags

Hi All,
I am trying to customize the AIA Error notifications in AIAEHNotification.xml file to include the html tags such as etc. to change the look of the error message. But the same is not getting reflected in the error emails I receive.
I'm sure the file AIAEHNotification.xml is getting updated as I can see my updated content every time but not html formatted in any case.
Does default AIA Error handler support HTML tags inside the email body message or it just uses <pre> by default before sending the notification?
AIA 3.0
SOA Suite 11.1.1.3

Neeraj,
html tags are not supported in the AIA EH notification framework as of now and I am not aware of any plans to support this in any of the next releases.

Using AIA for Error Handling. Logging and Notification Services

hi,
In our project we usie OSB and BPEL for integrating different applications.
There is a suggestion that we should use AIA to just use the Error Handling, Logging and Notification services from AIA. I am not sure about this use case, as most of these services mentioned can be replicated in BPEL. Except for the AIAAsyncExceptionHandling BPEL process, i guess all other functionalties provided by AIA can be easily developed in BPEL or OSB alone.
However, would like to hear from you guys about this particular use case. Is it advisable?

Receiving a DNS Solution Yahoo Error Handler Page and some pages won't display

I recently downloaded the Stuffit Expander and ever since then Firefox hasn't been the same. I receive a DNS Solution Yahoo Error Handler page when I do a search sometimes. And now some pages won't even display for me when they should. How do I get rid of this Yahoo thing (In simple terms please)? Thanks!

Thank you jscher2000! This seems to have fixed it! I appreciate it :)

Need to Turn it OFF the Notification used by the AIA Common Error Handler.

Hi All,
My requirement is to turn it off the Notifcation send by the AIA common Error Handler, when the error occurs in the AIA ecosystem.
Error Handling framework given by AIA does the Notification and Logging feature. In my case I need only the logging, but not the Notification. Notification has to be turned off for a time and has to be turned on when it is required.
1) I can acheive this by removeing the email account file (ie. ns_email.xml) from the server directory and can be replaced at the time when required,but this needs the restart of the Server.
Any Idea how to turn it off the notification and turn it on when required ?
Thanks,
Ashok.

Hi Rohit,
Thanks for your reply.
Is there any way to turn it off the Notification, because if we retire the ReadJMSNotification Service all the error message are stayed in the Topic and we have to manually drain the message from topic.
And one more thing is how the error messages are published to that AIA.AIA_Error_Topic.
Thanks,
Ashok.

Report and Alert don't executed in the error handler with a JMS proxy service

Hi,
I'm working with OSB 11.1.1.4.0 and I'm facing a problem with the error handler of my JMS proxy service.
My error handler contains two main elements :
- a Report action
- an Alert with a JMS destination defined
When the business service failed the message remain in the queue. It's the expected behavior.
The problem is :
- the report is missing
- the alert is raised but missing in the JMS destination defined in the Alert setting.
I've noticed if I add a Reply with Failure or Success, Report and Alert are successfully executed.
Unfortunately the message don't remain in the JMS queue.
What can I do in order to have my report/alert done and the JMS transaction rollback in order to keep the message in the queue ?
I've already met this problem in the past with alsb v3 and my solution was to add Service Callout in the error handler in order to externalize these actions.
This solution is not convenient and I hope another solution is possible.

Inventorying workgroups can be difficult, especially when it comes to remote access and network security. Because workgroups are not centrally managed, some of the items discussed in this
wiki article on preparing your workgroup environment may require you to visit each machine individually.
For non-domain credentials, you do not use the <systemname>\<user> format, you simply enter the user name. Regarding how to enter the credentials, if you have an account that uses the same username and password on all machines and is an administrator
on all of those machines, then you can enter that in the All computers credentials page of the wizard. You can also do this if they are different user names. However, if some machines have an account with the same user name, such as Administrator,
but different passwords on each machine, you will need to use the Manually enter computer names discovery method, and then enter the information for each group or each machine.
As you can tell, workgroup environments can quickly negate any benefit that the agentless inventory nature of MAP provides.

Error handling function: ORA-20001: get_dbms_sql_cursor error:ORA-00942: table or view does not exist is not trapped. Why?

Why APEX 4.1 Error handling function does not trap the error of missing table?
Say, I create simple application with single IR report page and I also assign standard simple error handling function.
Function works perfectly, except but this case:
If I just drop a table used by report page and then refresh the page I am getting usual APEX error message:
ORA-20001: get_dbms_sql_cursor error ORA-00942: table or view does not exist
and error handling function is not invoked at all.
Is this a feature or a bug?

BPM for error handling and acknowledgements

Hi,
Can any one tell me how to handle BPM for error handling and acknowledgements in one scenario.
Please send me the link if you have other wise give me the solution on the same.
Thanks,
Nagesh

Hi !
Just check out these links This might help you.
Usually Application Level Acknowledgement is considered during Sync communication. If you are using RFC, you can make use of Sync communication. So you can handle it without bpm, provided your both sender and receiver are sync interfaces.
To know about Ack-
http://help.sap.com/saphelp_nw2004s/helpdata/en/f4/8620c6b58c422c960c53f3ed71b432/content.htm
you can not dirrectly access the content of the ACK, however the BPM shows different behaviours based on the ACK status. E.g. if the ACK contains a success message the BPM will continue in its normal process, if the ACK contains a permanent error, it will either stop or go through an exception branch (provided such a branch has been defined). Have a look at the documentation: http://help.sap.com/saphelp_nw04/helpdata/en/43/65ce41ae343e2be10000000a1553f6/content.htm It doesnt"t state the above mentioned behaviour in detail but says that you need to define an exception branch.
The trickiest part is always to find out, when you will get a transient vs. as permanent error ack. If you are using ACKs with Proxies refer also to this link http://help.sap.com/saphelp_nw04/helpdata/en/29/345d3b7c32a527e10000000a114084/content.htm and this http://help.sap.com/saphelp_nw04/helpdata/en/f4/8620c6b58c422c960c53f3ed71b432/content.htm

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,
S.Suresh

Order blocked by user / Workflow error handling

Hi Folks,
I am getting this requirement quite often. Time to address it in a more efficient way than that I know.
The following is the requirement:
Workitem goes to approver. If the approver approves/rejects the workitem, there is a subsequent change in the sales order which is handled by BAPI in the next step. If the sales order is locked by some user, BAPI does not make change and throws an error.
Solution that I can think of:
The way it is handled right now is - if there is an error message from BAPI - the workflow is routed to a power user or an email message is sent to admin asking him to inform the right user.
This approach of mine does not sound correct. Can we actually throw error at the time when the approver tries to open the workitem itself (i.e. see if the transaction is being locked and if it is locked - throw an error and do not allow the approver to take action ).
Thanks,
aby.

Hi Aby,
If I understand this correctly, the sales order can be blocked by some other application during the approver's task?
Is the approval task a decision task, or a custom task? If custom, perhaps you could include some locking/unlocking code?
I suppose you could implement a before-method to check for a lock - but you aren't able to pass data back to the approval task from a before method. You could check for a lock in a separate task prior to the approval task, but there is no guarantee that the user would complete the task before someone else locks the object up again.
Another approach might be to check the results of the BAPI, and if it's throwing an 'Object locked' type of error, call it again. Of course, you would need to put some wait time in the BAPI, and also, you would need to ensure it does not go on waiting and trying forever. But nobody likes to admit they put wait steps into anything.
Just a few ideas to consider. I wonder if this problem is that persistent?

How to activate Forward Error Handling in SRM

Hello Gurus,
I got an requirement to activate Forward Error Handling in SRM. I have searched on SDN but didn't find appropriate answer on it.
Even I found some link: PI/XI: Forward Error Handling (FEH) for asynchronous proxy calls with the use of Error and Conflict Handler (ECH)
It explains me some points like activating FEH from SRM in SPRO. I have activated the same, plz check the screen shot:
It also follows some development for the same.
Here my concern is, should I follow this document? Does it applicable to all to all the scenarios?
Step 8: it assign object id and type what does it mean...
Does any one can explain me in detail..... Please provide me any document to configure the FEH in SRM.
I am trying to implement FEH in my SRM system. So that when even XML fails due to error, I should be able to reprocess/restart it with some editing to the XML.
My receiver interface for XML is PurchaseRequestERPSourcingRequest_In
I think this is standard one and no need to make any custom code for it. SAP has all ready given solution for it with some Configuration.
I have made some configurations like:
The view FEHV_ACTIVE must have the status active.
In transaction /SAPPO/LOGSYS , the logical system must be defined for the software component SRM-EBP-ESA .
As stated in in the link :
http://esworkplace.sap.com/socoview%28bD1lbiZjPTAwMSZkPW1pbg==%29/render.asp?id=2BAABCB0D30111DC2B8D000F20FCB6A9&fragID=…
Also I have made some configuration according to the Note: 1973768 - No reprocess option is available in FEH for failed in XML in SRM
Resulted, the “Process” button get activated in the XML Post Processing screen.
But can I reprocess my XML with edited value from there..?
All the configuration part of PI is already done .
I wanted to know about the FEH Part. what are the steps i am missing or where i am going wrong ?
Please let me help.
Thanks
Regards
Karan

Dear Raz,
I have gone with above mentioned note, it explains about creating Custom Proxy and configuration with PI scenario. Even the link in my previous post, explains about the custom proxies and configuration..

Error Handling in WebUtil CLIENT_OLE2.get_obj_property

Hello,
we have a problem with the error handling in WebUtil's CLIENT_OLE2.get_obj_property function. The WebUtil version is 1.0.2 and the problem can be reproduced on the 9iAS, 9iDS and 10gAS as well.
Problem description:
The get_obj_property function does not throw a PL/SQL exception when it is given an invalid object as first argument (i.e. an object handle to an application that has intermittently been closed by the user). Instead, the function returns a NULL value and the control flow of our application code continues as if the function had succeeded. So the problem is that the get_obj_property function neither throws an exception nor can the failure be caught by calling WEBUTIL_CORE.IsError as this returns that no error occurred.
Example:
PACKAGE BODY word IS
OBJ_HND CLIENT_OLE2.OBJ_TYPE := NULL;
mydocs CLIENT_ole2.obj_type;
-- Start Word97
PROCEDURE wordopen is
BEGIN
obj_hnd := null;
obj_hnd := CLIENT_OLE2.create_obj ('Word.Application');
CLIENT_OLE2.Set_property(obj_hnd,'Visible',1);
END;
PROCEDURE test is
BEGIN
IF obj_hnd IS NULL THEN
wordopen;
END IF;
BEGIN
mydocs := CLIENT_OLE2.get_obj_property(obj_hnd,'Documents');
EXCEPTION WHEN OTHERS THEN
-- Word has probably been closed by the user
-- so just start it again and retry...
wordopen;
mydocs := CLIENT_OLE2.get_obj_property(obj_hnd,'Documents');
END;
END;
END;
If the procedure test is called once then the Word application is started and the procedure performs some work. The procedure could be called several times on the same Word instance but fails in case the user closes the Word application because the procedure does not get an exception or error from WebUtil's get_obj_property function. Only a JACOB Java exception is logged in the Java console of the user's computer - the PL/SQL code has no way of knowing that an error has occurred.
Possible solution / patch for webutil.pll:
The webutil.pll can be patched to throw an exception if it is given an invalid object handle. In webutil.pll version 1.0.2 in get_object_property, line 1205, just add the condition "(v_javaHandle IS NULL) or " at the beginning of the if-statement in that line so that an OLE_ERROR will be raised if v_javaHandle is NULL:
if (v_javaHandle IS NULL) or (v_javaHandle = 0) or (v_javaHandle='') or (v_javaHandle=-1) then
raise OLE_ERROR;
end if;
Can you confirm the error and re-release a patched webutil.pll at a later time?
Regards,
Andreas Leidner
infoteam GmbH Berlin

Hi
It is mentioned in webutil doc that, you must regenerate webutil.pll before using it; otherwise you’ll encounter error ORA-06508 when running a form with the attached library.
Hope this helps...
