Business Event System in Workflow

Hi,
I am having difficulties with the Business Event System (BES).
Actually, I've read the Oracle documentation about BES. Still I don't understand much.
There are little documentation about the BES, and I still get blank point.
Here are my questions :
1. What the Business Event System is?
2. Some of documentations show that using the BES, the workflow can interact with
different system.
What does 'different system' mean?
Does it mean to another computer (perhaps Client Server type)?
Or to another system (like headquarter which has several branches) located in
different location?
Or to another database service in the same computer (perhaps ORCL and ORCL2)?
Or with another database applications (i.e Microsoft SQL Server, MySQL)?
3. How do we use the BES?
How do we define BES?
Where do we use the BES?
Is it using PL/SQL?
Or the BES itself is a PL/SQL which is inside a procedure or function or trigger (used
to manipulate the database)?
What does the BES look like? Is it a PL/SQL code, an e-mail, or ...?
4. Some documentations said that using the Event (with Receive type) as a start node
(in Workflow Builder), the process will wait and respon <u>until</u> a Business
Event is detected?
How do we interact with BES?
How do we know what kind of BES to start the process?
Do we use the Oracle Advanced Queuing?
Is it using an e-mail to start the Event?
5. There is a statement from the "Feature Overview Oracel9i Application Server : Oracle Workflow" (from Oracle site)
"Business event messages from Oracle Workflow can be placed on or received from Oracle9i Advanced Queues, providing support for Oracle Net as well as HTTP and HTTPS communication protocols."
and
"The Business Event System uses Oracle Advanced Queuing to propagate messages between communication points on systems, called agents, using a specified protocol. Events received from external systems are processed by an agent listener that runs on the agent's queue."
Actually what the Advanced Queuing is?
Is it the mechanism of scheduling activites such as sending a message?
Is it use to start the Workflow Background Engine periodically?
What does the Events received from external system is? Is it an e-mail?
If it is True, so the workflow process could be start using an e-mail?
6. There is also a documentation stated that the Event can be raised using the PL/SQL WF_EVENT.Raise() API.
The Event also could be launch using the Workflow Home Page (Workflow monitor) in Event link?
So what does the BES is used for, if the Event could be launch using a PL/SQL?
Is the process of raising the Event called BES?
Such as a procedure to manipulate database tables that consist the WF_EVENT.Raise().
What is Generate Function is?
7. What Agent is?
What Subscription is?
What Event group is?
8. Perhaps there is a guide book of using the Business Event System?
Any light would be grateful.
Many many thanks,
Buntoro

Hi
I am in exactly the same position...
Have queued up my events using wf_event and the subscription is putting them in WF_OUT ok.
So, I guess that WF_OUT is a multisubscriber queue, so when we register with it in BPEL it asks for us to identify ourselves using the consumer and/or correlation ID.
However, I'm with you in that I have no idea how to specify the consumer.
There is a CORRID column in WF_OUT and I'm banking on that being the correlation ID at the moment....
I'll let you know if I crack it!

What business event executes when a Party is updated

Hi,
What business event executes when a Party is updated ?
I tried with
oracle.apps.ar.hz.Organization.update
oracle.apps.ar.hz.CustomerProfile.update
None of these seems triggering when Party information is updated example: Customer Profile, Customer Name itself.
Thanks

Please see if (Customers Workbench: No Business Event Firing When Activating/Inactivating An Account Contact (Doc ID 1553927.1)) helps.

How to invoke BPEL process using Oracle Business Event System (BES)?

Hi,
I want to invoke a BPEL process using Business Events and Subscriptions (Oracle BES/Workflow). If anyone knows how this can be done, please reply to this thread. You can also mail me at [email protected]
Thanks,
Gaurav.

yeah you are 100% correct ..
I have attached some stuff for CDH integration, where we used plsql to send out info on a created record to a queue.
CREATE OR REPLACE
TYPE XXBPEL_MESSAGE_TYPE AS OBJECT (
MSG_ID VARCHAR2(128),
INREPLYTO_MSG_ID VARCHAR2(128),
FROM_PARTY VARCHAR2(512),
TO_PARTY VARCHAR2(512),
ACTION_NAME VARCHAR2(512),
MSG_TYPE INT,
PAYLOAD CLOB,
ATTACHMENT BLOB
EXECUTE DBMS_AQADM.create_queue_table (queue_table => 'XXBPEL_QTAB',queue_payload_type => 'XXBPEL_MESSAGE_TYPE',multiple_consumers => TRUE);
EXECUTE DBMS_AQADM.create_queue (queue_name => 'XXBPEL_OUT_QUEUE',queue_table => 'XXBPEL_QTAB');
EXECUTE DBMS_AQADM.start_queue(queue_name => 'XXBPEL_OUT_QUEUE',dequeue => TRUE,enqueue => TRUE);
On BPEL side creata a process that listens to this queue (with and AQ partnerlink) as shown in $BPEL_HOME/integration\orabpel\samples\tutorials\124.AQAdapter\MulticonsumerInbound

Configuring Business Event System of Oracle WorkFlow.

Hi all,
I created two queues in MQ Series. WF_JMS_IN and WF_JMS_OUT.
As I can configure my Business Event System Agents of Oracle WorkFlow to listen these lines of messages?

Intermittent Problem with Business Event.

Hi,
I have a problem with a BES Event. My suspicions are that the event is intermittently nor firing. It's custom code subscribed to '*.apps.ar.hz.PersonProfileExtAttr.Update' (an EBS Person Profile Extensible Attribute Update).
In the first lines of the custom code an audit is written to a table. For some one the updates to the Extensible Attribute no audit is written.
The table HZ_PARAM_TAB is cleared for the item
Q: Is there a way to prove that the BES Event did/did not fire?
Thanks in Advance,
Kieran.

Kieran,
Never experienced any performance issues when setting this profile option. However, you may review the following documents.

Migrate Business Events between systems

We are in the process of creating several dozen custom business events and subscriptions, and was wondering if there was a way to migrate them from one instance to another. The thought of having to key each event and subscription 4x (dev,test,qa,prod) is just begging for a typo.
Does anyone have any thoughts on how we can migrate them?

Thanks to Anil Passi for a quick response to my query. The information is available at:

Business events in r12

In r12.1.3 we have following business events when defining a concurrent program using Application developer or system administration responsibility
1. Request Submitted
2. Request on Hold
3. Request Resumed
4. Request Running
5. Program Completed
6. Post Processing Started
7. Post Processing Ended
8. Request Completed.Question:
What is the significance of above business events and how can we use it? Is there a documentation outlining each one of above events in detail? Is there any working example?
Please advise.
Thanks,

Notification Business Events

Hi,
I remember reading in the documentation that the Business Event System has a set of pre-defined events that correspond to Notification events like send, respond, cancel etc.
(Unfortunately I am not able to locate the exact document in which I had seen this listing).
The problem is that I am not able to find any notification related events in the business event list of my workflow installation.
I have installed WF 2.6.2 from ias902int(egration)cd into a 9.0.1.3.0 infrastructure db.
Notification Business Events would have been an extremely useful feature to have...Could anyone please tell me why I am not able to find these events? Am I doing something wrong or do they not exist in this version?
TIA,
regards,
Libin

Hi Raja,
Thank you for your response. I was able to find the listing in the workflow guide.
But I am not able to find these events in my installation.
I have used wfver.sql to double check that the version is indeed 2.6.2. There were no errors raised during installation and so far the schema appears to be fully functional.It is just that these particular events are missing.
Would you know how I could get these events inside the installation(any patch/upgrade etc)?
thanks and regards,
Libin

How to get Business Event Data in Oracle Apps?

The WorkFlow 2.6.2 Guide states that the XML Get Tag Value activity used to retrieve data from the contents of an event message is available only for the standalone version of Oracle WorkFlow. How do you retrieve the data from the event message using WorkFlow integrated with the Oracle Applications?

Hi Don
You have 2 choices:
1) You could access it programmatically by writing your own Workflow Function Activity using PL/SQL.
2) Oracle XML Gateway gives you the ability to create XML and consume XML documents using the Workflow Business Event System.
Cheers

Inbound using Business Events

Hi All,
We have to develop an inbound interface using business event to get better asynchronous mode of process between the middleware and Ebusiness Suit. The previous design was using a stored procedure by passing input parameter as table type (We had header line and details information in 3 different table type). Now instead of calling stored procedure middleware(ESB) will trigger business event by passing the input parameter. Please let me know how can I achieve this.
My main concern is if ESB is able to populate data via business event how can we process in our side.
I am ok even if we can get the data as xml also,, Please tell me how to achieve.
Please help.
Thanks,

Thanks.Please see "Business Events Region" in (System Administrator responsibility > Concurrent > Program > Define) window.
Concurrent programs can be integrated with the Business Event System in Oracle Workflow. Business events can be raised at key points of the life cycle of a request to run a concurrent program. Users can subscribe to the business events and create their own business processes interacting with the concurrent programs.

Hi Mohamed
In Workflow 2.6.2, you can load BES seed data using the wfxload command line utility. It is documented in the Workflow Guide.

Integrating Workflow Process and Business Events

Hi,
Im trying to use events in oracle workflow process..im trying to run the demo
process named 'Workflow Agent Ping / Acknowledge'. I have scheduled the listeners for local inbound agent WF_IN and propagations for local outbound agents WF_OUT. The master ping process begins executing and calls the detail ping process. The detail ping process begins execution but the process gets stuck on the receive event node.The process is not receiving the acknowledge event in return to the ping event. It does not move further,not allowing the detail ping process to complete, which as a result doesnot allow the master ping process to complete its execution.
How do i make it move?
Thankyou
Saadia

After launching the master process, check for the state of the message in WF_OUT queue. It could be that the message stays in READY state in WF_OUT and has not propagated to WF_IN queue.
Check if DB init parameters aq_tm_processes is set to 1 and it is running. If the message is not found in WF_OUT even after launching the proces, check if the queue is enabled for enqueue. Also check if the Business Event System is ENABLED.
SELECT text
FROM wf_resources
WHERE name = 'WF_SYSTEM_STATUS';
