How does a BPEL process instance know it has been cancel()ed?

The javadoc for the IInstanceHandle cancel() method says, "When an activity is cancelled, the performer of the activity is notified of the cancellation and is given an opportunity to rollback or cancel any work that has already been done on behalf of the activity."
How exactly is the performer of the activity notified? Some kind of fault? Can one code a "cancel handler" in the BPEL process, or is the "rollback or cancel" all done behind the scenes?
Either a full answer or a pointer to the appropriate documentation (which I haven't yet been able to find) would be fine. Thanks.

The BPEL instance can be canceled via the BPEL API or via console (Abort instance) or due to an error. Then the BPEL Process Manager will detect this and cancel the running instance. The instance will do a transaction rollback, depending if it was a global (XA) or local transactions. This whole mechanism is executed behind the scenes.

How to update the payload of a BPEL process instance

Hi I have another question.
How do I update the payload of a BPEL process instance without the activity being a Human Task. I know there are ton's of example showing how to update the payload of a user task using BPEL API's. But in my case I need to update the payload of a BPEL process instance which has no human task.

Thanks
For confirming that the payload in the BPEL process instance is read-only. Now I can see what alternatives I come up with besides the DB save option.
Guys if you can take the time to answer/comment on another question I have posted in this forum that will be great
here is the link

How to handle no of BPEL process Instances

Hi,
I am facing issue at my cleint. Here is the scenario
1) I have Business Event
2) BPEL is subscribed to event using Oracle Application Adapter
3) No every time new message comes in queue, causes new BPEL process Instances
4) So suppose there are 1 million message per day then BPEL Server is dying.
What is the best way to handle it?

This is managed via the dspMaxThreads and ReceiverThreads parameters, by default these are set to poor values, dspMaxThreads by default is set to 100 (domain level) whereas by default ReceiverThreads is set to 40. According to the performance guide the total of dspMaxThreads for all domains should be <= ReceiverThreads, so making some adjustment to the dspMaxThreads parameter should help.

When is an BPEL process instance created? Multiple creations?

Assume I have a BPEL process which a
RECEIVE at first, then some assignments and finally a PICK.
In the first RECEIVE and the later PICK I can enable the checkbox
"create instance". What is the difference?
When I call the BPEL process from the BPEL console it is instanciated. Ok.
But what happens if the workflow arrives at the PICK?
Is it instantiated again?
How comes?
Similar question: Assume I disable "create instance" in the first RECEIVE
and enable it only in the later PICK. Does the BPEL process start only
from the PICK stage and disregard the preceeding commands ?
Peter

Hi,
The createInstance flag tells the bpel engine it has to create a new instance of this process, and not to correlate the message to a created bpel instance.
If you insert a pick with createInstance attribute, your process will be hang for ever. You won't be able to send a valid message to you pick since all your messages will go to the first receive activity.
For your other question, activities other than start activities (scope,sequence, empty, receive, pick) must not be performed before start activities.
The bpel process should not even build since all your previous activities won't be after a start activity (except if these are <empty> ...).

Help: how does a container process requests?

I am reading the specification of servlet, but it just confuse me a lot.
Some one know any of the following please help me. thanx.
how does a container process requests?
does it process one request per thread?
or one request one time?
a new request can only be accepted after the current request responsed?
thanks in advance.

paulxue wrote:
and most important finding is that container execute the doGet or doPost method in different threads for requests.That is, a single HTTP request is entirely executed in a single thread.
does this mean it may be Dangerous to have fields in a servlet? since they may be accessed by many thread at a particular time.The general principles of Java Concurrency hold true for Java servlet as well. Main point is understanding what you are doing.
finally,when will the instance be destroyed?The instance will be destroyed when web application lifecycle ends. For eg: when the servlet engine is stopped or restarted

The log entry shows that user : WALMART is missing on your user-properties.xml file.

BPEL process instance getting created twice

Hi,
We have B2B - BPEL integration developed using AQ and we are using this for importing 850 Purchase Orders. It is a simple flow involving dequeuing 850 transaction message by the AQ adapter and processing the message through Receive, Transform and Invoke activities to invoke a PL/SQL procedure to insert data into the Order Management Open Interface tables.
The issue we are facing is that the BPEL process instance is getting generated twice resulting in duplicate rows in the interface tables.
Please if any one faced this kind of issue, let me know the solution.
Regards,
Balu

This issue is closed. We were able to identify to cause for the issue. The EDI document came in with two POs which generated two separate messages.

How does the sync process work?

Hello all,
I want to know what will happen if both the local and network homes have been modified for a period of two weeks and then the user chooses to synch? Will the sync process ask which 'home' is the most recent or will it replace older files with newer files?
How does the sync process manage the task of keeping both sides the same?
Thanks,
-Andrew G

If a file exists on both the local and the network directory it will pop up with a conflict and ask how to resolve it.
If the file is only on the local machine and in a place you have not excluded from syncing it just syncs.
If the file has been previously synced but there has been no change to the file since last sync I think it just rewrites the file to the server homedir... (Don't quote me on this one... it might not even bother with it, I'm not sure how smart the sync service is)
You can set automatic conflict resolution within WGM but as far as I know you have to do it by clicking on preferences then switching to the details tab, then click on Home Sync....com.apple.homesync. Click on the Always drop down and click the add new key button then change the new key to either Login or Logout Non-Preference sync conflict resolution and or Background sync conflict resolution and decide if MobileHome or NetworkHome Wins...or copy. In most cases I would think that you would want the MobileHome to Win.. of course there is always potential for someone to make a huge mistake on a file and pray its still fine on the server but... your call.

How does a BPEL different from ESB?

How does a BPEL different from ESB?

BPEL and ESB are similar on higher level,
they can both be used to integrate system/process and make data flow between them.
BPEL is for designing process
1.) Where human task is involved
2.) Lot of complex looping is there
ESB
1.) Its designed for integrating different system/process and make data flow between them,
2.) Its designed to do this very purpose, so fast in comparison to BPEL to do this

How to get child process instance id from main process

Hi All,
I have a main process invoiking a child process 1 and child process 1 inturn calling child process 2.Is there any way to get the child process 2 instance id from main process or main process instance id from child process 2.. Using tree finder in BPEL Control i can find the direct sub process(child 1) instance id from the main process instance. Is it possible to trace Sub process 2 instance id without going for the instance detail of sub process 1.
Thanks in advance
ChitraDevi

you could easily derive this from the bpel cube_instance table. using cikey and parent_id columns. you can use IInstanceMetaData javadoc, it has method called getParentId( ) to get the id. you can get the root id (instance-id of the main bpel process instance) using getRootId( ). you can checkout this blog.

TRFC internals - how does the async processing happen?

tRFC internals - how does the async processing happen?
Dear all,
With the document "[https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f078394a-4469-2910-c4bf-853c75674694|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f078394a-4469-2910-c4bf-853c75674694]" there is an excellent place to read about SAP RFCs (remote function calls).
Pages 94 to 96 describe in detail how tFRC (transactional RFC) works.
However, there is still something unclear for me with the following sentence on page 94:
"The truly exciting part happens when the program
issues a COMMIT WORK command. The recorded calls
are executed asynchronously in a special set of tRFC
processing sessions created for each transaction ID..."
Maybe someone can answer the following questions:
a) what does exactly trigger and execute the tRFC?
b) is it the ABAP runtime system itself, spawning the additional task in DIA?
c) if multiple tRFC LUWs have been recorded, they are all executed in parallel by this procedure!?
d) does the execution try to utilize all available DIA processes?
e) how do the rdisp/rfc_... parameter come into the game?
   are they evaluated? We have seen all DIA occupied by the tRFCs executed!
Best regards,
Peter
P.S.: if someone has answers to these ones, more related to error handling, would be great as well
f) the jobs ARFC*, do they also use parallel processing?
   or is every ARFC* job responsible only for one single LUW?
   (note https://service.sap.com/sap/support/notes/366807 did not give a perfect answer)
g) and how does the report RSARFCEX work compared to immediate execution?

That's the problem, it won't.

This piece of code looks at the SPDatabase's connection string (the SQL alias, for example) and executes a T-SQL query looking for that name within SQL Server. Since the SQL alias does not exist within the SQL Server's configuration, it will return a null
value, and you won't be able to set up the AG config using the AG cmdlets.
Also, since mobility exists by the very nature of using an AG Listener, using a SQL Alias is redundant.

How to trigger BPEL process from DB insertion

hi,
How to initiate BPEL process when a row insert, update or delete from table.my concern is to handle different casses for all above mentioned DML.

Check if there is are Out of the Box Events first, if there are use those. Otherwise use a custom database trigger on your custom table. Make sure that your call is not being inadvertenly called multiple times.
