Qs on Basic BPEL/ESB Async process

Hi,
I am curious to know that how re-tryable exception happens.
I designed below process and couldn't come to any conclusion:
BPEL Process 1 (Aync) -> ESB 1 (Sync) -> ESB 2 ( Async) -> BPEL (Sync)
Now here when i put my BPEL service down and initiate BPEL process, i can re submit the service back using console.
when i change to
BPEL Process 1 (Aync) -> ESB 1 (ASync) -> ESB 2 ( Sync) -> BPEL (Sync)
I can still re try (re submit using Console).
when i change to
BPEL Process 1 (Aync) -> ESB 1 (Sync) -> ESB 2 ( Sync) -> BPEL (ASync)
i can not retry or resubmit using console.
Can any one tell, what is the basic idea behind this, why some time re submitable and some time not. even i make ESB 1as Asyn or ESB 2 as Asyn still does make any difference to retry.
What is the basic concept.

Scheduling a BPEL/ESB process

Hi,
We have a requirement to invoke a BPEL/ESB process (Reading from DB) at a particular time every day. I got the following options from Clemens Blog:
1. RDBMS Scheduler
2. Quartz
Kindly let me know which will be a better option, provided we need to trigger the BPEL/ESB process every day.
Any help will be appreciated as this is very urgent ...
Regards,
AP

You could make a list of pro and cons of the two solutions. It depends per project how this is implemented. From SOA point of view you could chose Quartz, but I also see customers using RDBMS scheduler while the DBA is more confident with this. I also see customers using the O/S scheduler like the 'crontab' in unix or the Windows equivalent.
It's hard to give you an advice, while I do not know the business requirements of the customer.

BPEL/ESB Errors to Worklist app

Hi All,
I have a requirement in which I have to bring the error message for all the errors that happen in BPEL and ESB to the worklist application. I have used BPEL fault policy and BPEL client API to implement this in BPEL and listened ESB_ERROR topic to implement this in ESB.
Now I want one 'RESUBMIT' outcome to appear in the task details if these errors are retryable. My odubts are:
1) How can I find out which errors are retryable in case of both BPEL/ESB ? I found a Retyable field in ESB_FAULTED_INSTANCE table in ORAESB ; but not sure how to use it . How can I find out the same for BPEL?
2) How do I add the Outcome 'RESUBMIT' dynamicaaly to the task whenevr the error type is retryable?
Please pour in some ideas on how to implement this....
Thanks.

Please deploy the bpel project and then you can locate it in the bpel console.
Then ,initiate the main process and only then log into the worklist app with the correct port number.
Then login with the correct user credentials and will be able to see the tasks allocated to him.
P.S.:Unless you initiate the process in BPEL Console , you cannot see the tasks for the user in worklist app.

JDeveloper BPEL/ESB Designer

I'm going spare trying to set up a version of JDeveloper with the BPEL / ESB plugin.
I have found and tried to follow Oracle documentation fo the BPEL Process Manager which claims that JDeveloper with BPEL Designer is installed with BPEL Process Manager (10.1.3.1.0).
Once installed where the documentation claims is the link to run JDeveloper is just a HTML page telling you to download and updated JDeveloper but the BPEL update is not in the list of possible updates.
Google has lead me to go old school and find an old Eclipse Europa install and try an out of date plug in but thats not working either (not that its much good even if it did)
Any help as to where I can actually find what I am looking for or just a pointer to any tool where a newbie can start developing some BPEL would be greatly appreciated.
Thanks in advance,
Chris

Not sure what documentation you have read but JDev does not get installed as part of the 10.1.3.1. It did with the single user license of 10.1.2
here is the link, just unzip and play
http://www.oracle.com/technology/software/products/jdev/htdocs/soft10134.html
Please not that this is 10.1.3.4 and is only certified for SOA Suite 10.1.3.4. If you are using 10.1.3.1 then install JDev of that version. I would recommend upgrading SOA Suite to 10.1.3.4 as 10.1.3.1 is old. Part of the 10.1.3.4 install is installing 10.1.3.1
patch is found here http://www.oracle.com/technology/software/products/ias/htdocs/101310.html (There is a patch link in the 10.1.3.1 install) Don't be surprised with the size of the patch as it looks like a fresh install. You just install into the same home as your 10.1.3.1 install.
cheers

Async process

hi,
i have a question. if u have a async process then u send several request and u may or may not receive response immediately.
Then, how can soa infrastructure relate - whenever the response does come "Which response is meant for which request" ? How does it relate correct response to the corresponding request ?
is it taken care by soa infra automatically ? or does developer need to do specific in bpel to correlate ? any good doc on this requirement appreciated.
thx

quick amendment to the previous post - in case your service does NOT support ws-addressing you can use the correlation set feature in BPEL (content based correlation). Mediator (in 11g) sets its own correlation id into the request.

Jdeveloper CVS for BPEL & ESB projects

Hi All,
In my project, we have decided to use CVS (integrated with Jdeveloper 10.1.3.4) as version control system for BPEL & ESB project codes.
In this regard, I would like to know what are the best practices followed in scenario like this,
I have 8 to 10 BPEL & ESB projects related/dependent on each other which were developed for a project release XYZ. We would like to organize the code in CVS based on project's release. For example group BPEL & ESB projects under one logical group name.
XYZ
|--> BPEL Project 1
|--> BPEL Project 2
|--> ESB Project 1
|--> ESB Project 2
|--> BPEL Project 3
My question is, should I treat each BPEL & ESB project as a module or should I treat project release XYZ as a module.
In later case, I think I would end up checking out/in all BPEL & ESB projects under XYZ eventhough I wanted to work on only one BPEL/ESB code. Not sure if this is acceptable.
In former case, I would be able to checkout & checkin only the BPEL & ESB code which I would like to update without impacting any other code.Which I believe as acceptable. Since I already have a parent repository 'PQR' should I have to define XYZ as a sub repository to PQR. At end of the day,we would like to make CVS appear something like this. Since I am new to CVS do you see any disadvantage with this approach.Your help is greatly appreciated.
PQR
|-->XYZ
|--> BPEL Project 1
|--> BPEL Project 2
|--> ESB Project 1
|--> ESB Project 2
|--> BPEL Project 3
|-->YYY
|--> Java Project 1
|--> Java Project 2
Thanks,
RA

Hello Naresh,
As per my knowledge you can migrate through instances in two ways.
One way is to modify the build.properties file with the host information of you destination systems, changing the build.xml file with the proper wsdls. In this case you would risk providing the PROD passwords as you need to provide them in the build.properties file.
The second way is to build ant scripts which are run on the server and the processes get deployed on the Application server.
Thanks

AIA or BPEL/ESB for Integration ?

Hi All,
I know that this question has been raised many times on this forum. :)
But still I want to know the main difference between the integration development using AIA or BPEL/ESB ?
Which one is better in which scenario and why.
Please throw some light on this.
Cheers,
KK Chopra

<div class="jive-quote">
What if I am integrating two custom application where I am sure that a pre-build PIP will never be available.
What do you suggest?
What is the value add of AIA except XSD and WSDL?<br>
<br>
</div>
Check out AIA Foundation Pack which can help you to build PIP between any custom applications.
Well such XSDs and WSDLs can be downloaded from OAGIS. But hold on AIA gives you more than that.
Some of the things which I can see in AIA ....
- Just by using SOA tech stack - BPEL/ESB/XSD/WSDL one can't achieve true SOA. AIA teaches how exactly we should build integrations using these technologies to get SOA values.
It has proven reference architecture that consists of documented best practices,design patterns and template to help to accelerate your approach to SOA.
- AIA's EBOs (XSDs) and EBSs (WSDLs) are already practiced for bunch of integrations between different applications. They are much more matured. Also AIA has best practices for extending,versioning these artifacts.
- SOA governance tools like SOA Repository,testing integration scenarios,error-handling
- Conceptual models of End-to-End business processes which are application independent.

How to read JMS message properties from BPEL or BPMN process

Hi all,
I have a JMS Adapter that consumes messages from a remote ActiveMQ queue and I don't find the way the get the properties of the JMS message as I would like to map them in BPEL or BPMN process variable. I only manage to get the content of the message.
I've also read that if using a MapMessage, one of the map entry can be mapped directly and that the other map entries go to jca.jms.Map.xxxx where xxxx is key of the map entry.
But how can I map those "jca.jms.Map.xxxx" properties on process variables ? and how to map JMS Properties (that seem to be mapped on jca.jms.JMSProperty.xxxx) to process variables ?
I use SOA Suite version : 11.1.1.4.0
Thanks for your help

Wli async process restarting itself with server restart

Hello
I have an async process calling a sync process in a wli server that calls an ejb in a diff wls server that runs a long operation. When I kick the async process and the long operation starts, if I shut down the wli server before the operation ends and restart it, the async process seems to kick off by itself. Not sure what configuration controls this. Please help.
thanks

Are you running your WLI domain in production mode?

BPEL with Reliable Processing

Hi,
I read and work on the "BPEL with Reliable Processing" cookbook.
http://www.oracle.com/technology/pub/articles/bpel_cookbook/qualcomm-bpel.html
It's great!
I try to enhance the process by adding notion of priority between different records.
A priority-based process will favour those processes with high priority values.
To achieve that, I made the following modifications:
1) Add the "PRIORITY" column into the "DB_POLL_SOURCE" table.
CREATE TABLE "DB_POLL_SOURCE"
"ID" NUMBER (17,0) NOT NULL,
"VALUE1" VARCHAR2 (32),
"VALUE2" VARCHAR2 (32),
"VALUE3" VARCHAR2 (32),
"PROCESS_NOT_BEFORE" DATE,
"RETRY_COUNT" NUMBER (7,0) DEFAULT 0 NOT NULL,
"BPEL_STATE" VARCHAR2 (16) DEFAULT 'P_NEW',
"CREATED_DTS" DATE DEFAULT SYSDATE,
"MODIFIED_DTS" DATE DEFAULT SYSDATE,
"PRIORITY" NUMBER (7,0) DEFAULT 5 NOT NULL
2) Add an order by clause to sort the "PRIORITY" column in descending order.
3) Add the where clause (rownum<N) for getting the first N records from the query record set.
CREATE OR REPLACE VIEW DB_POLL_SOURCE_VW
(ID, BPEL_STATE)
AS
select *
from (
select
dbps.ID,
dbps.BPEL_STATE
from
DB_POLL_SOURCE dbps
where
(dbps.PROCESS_NOT_BEFORE is NULL or dbps.PROCESS_NOT_BEFORE < SYSDATE)
and dbps.BPEL_STATE like 'P_%'
order by dbps.PRIORITY desc
where rownum < 5
The problem is that the view must be updatable and ROWNUM cannot be used inside an updatable view.
The message error I got is the following:
ORA-01732: data manipulation operation not legal on this view.
So my question is:
How can I define an updatable view to sort the "PRIORITY" column and then limit the number of rows returned?
Thanks a lot
Olivier

If you want to update a view, you must use database triggers to perform this. You can user the statement:
CREATE OR REPLACE TRIGGER <triggername>
INSTEAD OF INSERT (or other UPDATE/DELETE or both)
ON <view>
FOR EACH ROW
BEGIN
.. PLSQL code here ..
END <triggername>;

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.
internal static string GetAvailabilityGroupFromConnection(SPDatabase db)
if (!UsesAvailabilityConnection(db))
return null;
string dataSource = db.ConnectionString.DataSource;
string cmdText = string.Format(CultureInfo.InvariantCulture, "\r\n SELECT name FROM sys.availability_groups g\r\n JOIN sys.availability_group_listeners l ON g.group_id = l.group_id\r\n WHERE dns_name = '{0}'\r\n ", new object[] { dataSource });
string str3 = null;
using (SqlCommand command = new SqlCommand(cmdText))
ULS.SendTraceTag(0x302263, ULSCat.msoulscat_WSS_Database, ULSTraceLevel.Medium, "Looking up availability group for listener: {0}", new object[] { cmdText });
using (SqlDataReader reader = GetSessionFromDatabase(db).ExecuteReader(command))
while (reader.Read())
str3 = reader.GetString(0);
ULS.SendTraceTag(0x302280, ULSCat.msoulscat_WSS_Database, ULSTraceLevel.Medium, "Found group {0} for listener {1}", new object[] { str3, dataSource });
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.

Mechanism to document bpel/esb code

Is there any mechanism to document bpel/esb code?

Hi
I made a mistake.... I copied the wrong error message from the ESB console ..... The response code is 500 and not 401.......
Here is the message at ESB console :
An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message transmission failure, response code: 500 at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeOperation(WSIFOperation_JaxRpc.java:1720) at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeRequestResponseOperation(WSIFOperation_JaxRpc.java:1466) at
and in the WSM gateway error is :
Error message - Service returns soap fault: Fault Code=[:XXXXX_yyyyPortType] Fault String=[Cannot figure out operation name. Bad SOAPAction or wsa:Action.];

Async Process A calling Async process B. Process B is throwing Error.

Hi,
I have one scenario like Async Process A is calling Asnc process B. now if process B fails, how would process A will come to know that process B has failed.
~rps

Hi' Sri,
I missed the Async/ sync, you are correct the reply will work for sysnc process,
For this
1.) We can have to first modify the XSD and add extra elements (other then input and output) for faults
ex: remote fault, etc.
2.) Modify the WSDL manually to include this elements, in the similar way as input and output are there.
3.) Inside the process B put a catch and use a assign activity and assign the values for the exception
(usually hard coding is done and description is given by ora:getFaultAsString()).
this values will go in the variable which we will create and will be of the the same message type as created in the WSDL

Oracle BPEL/ESB/SOA vs SAP XI

Hi,
Wondering! What would the percentage of implementations SAP XI vs Oracle BPEL/ESB/SOA for next couple of years. I just wanna explore and know more about them.. How's Oracle SOA/BPEL/ESB doing in terms of new customers/implementations and what are all market trends and future jobs.. Also throw the light on SAP XI side... Is it wise to choose Oracle BPEL/ESB/SOA to get better jobs? Every one talking about SAP XI etc... How about Oracle Fusion?
I appreciate your opinions/facts/guess or whatever.
Thanks in advance..
Giri

Giri,
SAP XI is something centered around SAP implementations and I am not very much sure of its architecture.
On the other hand when it comes to BPEL, SOA, ESB, they are all industry wide standard and Oracle is just one of the vendors providing tools to implement the solutions based on these industry standards.

Hey
i m not sure about the Oracle products but as far as SAP XI is concerned, its picking up in US.SAP is now recommending to use XI for all the integration instead of Point to point integration as was done earlier.more and more SAP customers are adopting XI and as the market for SAP grows , XI is bound to grow.
just my suggestion
