Sensors in BPEL

Hi,
Summary:
      Problem is the records in the VARIABLE_SENSOR_VALUES table are not deleted in after deleting the Instance.
Detail:
    I have created the simple bpel service and I created the simple variable sensor for the bpel by creating the activity sensor as DB publish type.
    Whenever I test the bpel service in Fusion Middleware, I am seeing the variable sensor values ==> No Problem
    I run the 4 instances, for all 4 instances, I see the sensor values in Table (VARIABLE_SENSOR_VALUES) for the bpel with intance id. ==> No Problem
    I have the records also in CUBE_INSTANCE table for that 4 instances ==> No Problem
    Now, I deleted the all the 4 instances in Fusion Middleware, and checked in the Table CUBE_INSTANCE, found no records for those instance ==> No problem.
   But, Still the values are persisted in VARIABLE_SENSOR_VALUES table even after the 4 instances deleted.
   Please help on this.

Hi Marc / Anirudh
Thanks a lot for providing information. But the clients want the results to be displayed on a Different JSP page. I have created that page. Now I am looking to pass the Payload (The results of the BPEL process) to this JSP page so that i can display over there. I have googled it but didnt find anything. Then i came to know that something like sensors can do it. I have no clue about it. Kindly help

Data not display in BAM Dataobject through sensor in Bpel process.

Hi,
I am trying to integrate BAM with BPEL process in oracle 11g. I have created BAM Activity and variable sensor

How to see data in BAM from sensor on BPEL activity?

Hello, I 'am working with BPEL on Jdeveloper (last version).
I have putted sensors on some activity of my process. On an other machine I have putted the BAM server (last version) which is ON and I have the BAM connection on Jdevlepper. Now I try to see data on BAM from sensor but I can't.
Can someone explain me how to do?
(I just can build some data just like in a data base with BAM architect but I can't read and put to graphics the ones from the sensors)
Thank's much
JAck

Hello,
To answer your question, I have install BAM on the same machine where BPEL server is running.
Now I steel can't get sensor's data from BPEL:
With BAM architect I can build data, with BAM studio I can use that data to design graphics but when I try to feed data from BPEL it doesn't work because I just can't press the OK button!!
In BPEL : When I try to Create BAM sensor action (from structure panel), I can't generate the xsl map file no action is done when pressing OK, create mapping or edit mapping button!

There are two ways to get data into BAM. There is the ADC web service that BPEL uses and then there's Enterprise Link which is the ETL tool that can grab data from Databases and other sources. I only used EL for jms and for ETLing data into a a BAM data object, I never used it for real time. The only real time BAM I've done is with BPEL projects with BAM sensors. I don't think EL is sophisticated enough for looking for changes in rows of data.
Maybe you can have a db trigger that publishs the changed data to table specially designed for your task. Then you can create an EL "Plan" that runs periodically at a high enough rate that it appears to be in real time in BAM.
Another possibility is to have the db trigger fire off an xml message that contains the data to the BAM ADC webservice. The BAM ADC web service is http://server:port/OracleBAM/Services/DataObject/DataObjectOperations.asmx.
It has documentation on how to use it. I don't know if you're db can execute application code or not though.

Sensors in BPEL to publish data to JSP page ??

Hi Guys
In the BPEL console the result comes in a XML format. I want the result to be displayed on a JSP page that i created. So that the end user is comfortable to see results. I wanted to know can sensors be used to capture the results from the BPEL console and publish it on the JSP page. If we can do it, which kind of sensors will work. If you could provide me some examples on how i can do it .. It will be really helping . I am new to BPEL and need to complete it urgently. heLp required

BAM Sensor in BPEL

Hi,
I'm new to BAM and am trying to use a BAM sensor in my BPEL process to populate the BAM data objects. I've created a BAM sensor variable and corresponding sensor action. The BPEL process executes as expected but the sensor does not seem to reflect any data.
I'm obviously missing something but not sure what - I'm using SOA 11.1.1.3 and have tried using both activity and variable sensors.
Any help would be much appreciated.
Thanks,
T

Make sure you have the BAM adapter configured.

Hi
I have BAM Sensors in BPEL process at various activities. The data is published to BAM DO. How to check the logs, payload any details related . The sensor tab in the BPEL COnsole...Does that show any details....bcoz I dont see anything there....
What is the sensor tab on the BPEL COnsole for??
Guide where to look the excuted sensors payload and whether it executed succefully or errored out..
The only place where I go and look now is domain.log in BPEL and BAm Server log.

Variable Sensor with Custom Java as Sensor Action.

I am trying to use Variable sensor in BPEL (SOA 11gPS3). I am using Custom Java as the sensor action (Publish target as demo.MyPublisher) .

BPEL vs ESB

Hi,
I want to raise this oft-repeated question and compile all the information in one thread.
The following are the points of comparison between the two that I can think of. Please verify and add to the list:
Use ESB: The payload has everything needed for transforming into the output format
Use ESB: Transformations and invocations are simple, say sequential
Use ESB: Stateless
Use ESB: Memory footprint - smaller for ESB for similar project (say developing a program that reads a DB and writes a file)..can somebody provide any figures
Use ESB: When you want to use DVM (BPEL does support DVMs via lookup-dvm, but its easier to use them in ESB)
Use BPEL:Orchestration required
Use BPEL:Long-lived or chatty application
Use BPEL:Need to send notification
Use BPEL:use business rules
Use BPEL:splitting joining of payloads - maybe this is possible in OSB
Use BPEL:content validation required based on business rules (and not necessarily xsd based)
Use BPEL: when participating apps support only HTTP/XML
Use BPEL: WSDL operations having multipart in messages
Use BPEL: Need to send binary attachments
Use BPEL: Monitoring using BAM etc. BPEL offers sensors
Use BPEL: Require control over error handling. BPEL also supports fault policies (not sure if ESB supports these too)

Use BPEL: WSDL operations having multipart in messages
For this recommendation what is the reasoning behind? And is there a way to get around it in ESB?
I am creating a pass through routing service for an already created client service that has multiple parts for the input and output. I have found a workaround in jdeveloper for being able to create the service by starting jdev using :Start jdeveloper.exe -J"-Dpreview_mode=true" which indicates that you cannot transform any of the values- which is fine for my services for now, but now I am finding that my routing service is only passing through the first part of the input message and I am getting the following error:
The message Returned from the call is returned as HTML as an Error 500-Internal Service Error
Error Message:
oracle.tip.esb.server.common.exceptions.BusinessEventRetriableException: An unhandled exception has been thrown in the ESB system. The exception reported is: "oracle.tip.esb.server.common.exceptions.BusinessEventRetriableException: An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: exception on JaxRpc invoke: serialization error: java.lang.ClassCastException: oracle.xml.parser.v2.XMLElement
I can see the payload that is being passed to the SOAP Service is only the first part of the message.
Any suggestions workarounds?

This is a regression. Sensors should not be visible until the 10.1.2 release. This regression will be addressed in the 2.1.2 patch release. -Edwin

Error:JCA Binding execute of Reference operation 'writetoBAM' failed

Hi All,
I have two different environment, On which BAM server is installed and configured on both. Both servers has same folder structure for Data Objects. I have created "abc" data object on server1. Implemented sensors in bpel. deployed respective composites on server1, bam sensors works fine. I am able to get data in data object.
Now i have manually created similar data object "abc" on server2 having same column as in "abc" data object on server1. Deployed composites on server2. Now found BAM sensors are not working am not able to get data in "abc" data object on server2
Found error in soa-diagnostic.log :

How BAM can use to monitor B2B process?

We have a BPEL process that is using B2B piece for connecting Trading partner and want to monitor whole process from Start of the BPEL to end of the B2B.
Here are the questions.
Q1. We know by using BAM sensor on BPEL process we can monitor the BPEL prcocess but how about B2B piece?
Q2. What are the best practices for capturing and reading transactional data in various phases and functional acknowledgement messages from a B2B server?
Thanks in advance for your reply.

Please send a note to [email protected] for a document on BAM-B2B integration.

Effect of 'In-Memory' persistent store for JMS destinations

All,
We have many BPEL processes running on 1013 and we uses sensors to publish data into JMS-Topic destinations whose persistent store is 'In-Memory'.
when we bounce the oc4j (opmnctl stopall)
it always says one of components failed to stop
Shutting down forcefully...
Now my question is, If stopping oc4j is not graceful, Will my JMS messages be lost ?
regards,
Praveen

We are on soa 10133.
We see lot of problems with JMS In-Memory persistent store.
We have sensors in BPEL which publishes to JMS topics and we have BPEL as consumer which takes and inserts into database.
We see some times data getting inserted into data base and some times we do not see insertion though we dont see any errored bpels in console.
I suspect sensors are failing in publishing messages to topics becaz if consumer BPELs are failing we see them in console.
Anybody has any idea for what reasons sensors fails
and also what is performance impact if we use file-based JMS store?
Regards,
Praveen

KPIs in Oracle BPA Suite 11g

Hi everyone!
Is it possible to define KPIs in BPMN model, so that those KPIs are translated to BPEL sensors upon BPEL translation?
It seems that checking the Calculate activity processing time on BPMN activity does not work.
Thx,
Sonny

hi Paul,
Thanks for the link..I have one doubt in this..Can you tell me where the xsd location of xref will be there ?
In the document he has given the
For custom database tables, two additional attributes, namely mode and dbtable, are added to the schema definition mentioned in Section 46.3.2, "What Happens When You Create a Cross Reference." They are added for the table element in the following way:
<attribute name="mode" type="string" default="generic" />
<attribute name="dbtable" type="string" default="xref_data"/>
Need to add this attributes in the xsd..Can you tell me where the xsd location resides ?
Example 43-1 Cross Reference XSD File

Oracle BPEL Process Manager 10.1.3.x sensors and Oracle BAM Server 11g TP4

In Oracle Fusion Middleware Developers Guide for Oracle SOA Suite in section 42.5 there is the next:
"You can also use Oracle BPEL Process Manager 10.1.3.1 sensor actions to publish sensor data as data objects on Oracle BAM Server 11g"
Is it really possible?

Hi, Please post this in BPEL forum, not here.
