Activation agent trouble

When i am deploying bpel process which connect to SybaseDb i have
An error occured while initializing an activation agent for process "Test", revision "1.0".
Please ensure that the activation agents are configured correctly in the bpel deployment descriptor (bpel.xml).
Once this problem was solved editing adpter.wsdl
mcf.PlatformClassName="oracle.toplink.platform.database.DatabasePlatform"
changed to
mcf.PlatformClassName="oracle.toplink.platform.database.SybasePlatform"
Everything works well, but now i have the same problem and this trick doesn't help
Any ideas
Best regards

I would turn on logging to a higher level:
Configuration->Logging-->domain.collaxa.cube.activation
and see the domain.log for the cause of the error.
You should see a line - shutting off Activation Agent or something like that. It will give you a direction, or at least some more information to log an SR.
Thanks

Activation Agent in SOA Suite 11g

Hi,
The 10g SOA Suite has the activation agents for the BPEL PM - that can start process instances from the reception of an Email for example.
So far, I have not been able to find something like this in the documentation. I am wondering whether there is or will be a mechanism in the 11g SOA infrastructure to have the reception for example of email messages or IM (Chat) messages be processed potentially leading to new service instances. Or would I need to create a custom 'polling' solution for this.
thanks.

Hi,
I have placed my transformations in shared folder inside MDS & pass the transformation file to the Oracle SOA transformation function as oramds:/apps/<transformation file name>, i.e in my case I have put the transformation_example.xsl in /apps/testing folder, so I passed oramds:/apps/testing/transformation_example.xsl. I don't deploy shared transformation with composite but put it in shared location.
Your case should also work, look like to me the path issue, jdev ide by default creates all transformation file inside xsl folder, but in the path does not have xsl folder. Check the MDS repository & verify oramds:/deployed-composites/default/DB_Event_rev1.8/Transformation_2.xsl is right.

Problem calling a EJB Java Client from Java Activity Agent

Hi,
We have a wrapper java class that calls to an EJB through a JNDI lookup. The wrapper class is called from a workflow. The problem is that the call fail with the following message error:
Error : getRemoteHome Lugar: ServiceLocator NamingException Mensaje Error: Receive timed out
Mon Jan 09 15:32:13 EST 2006 Enqueuing VIC/97513 com.tallion.tax.workflow.assessment.Update

The wrapper class has in their classpath a jndi.properties as follows:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=69.0.137.120:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
The call just works fine when we restart the Java Activity Agent and then, after a while it fails again with the same error.
Any ideas/workaround?
Thanks.

I have a situation that is a bit similar. I have successfully used beans for storing methods used in JSPs and used by other methods in the same class as was suggested above. Now I would like to break some methods into another (utility) class since they are lower level and can be used by lots of things. They are for database operations (given a String query and String dbname, it queries and returns ResultSet for example). I want to have them in a separate class for reusability and OOP.
I am having problems calling those public static methods in the public class from my bean that communicates with the JSP. I can't compile the class that calls the method in the database ops class. I get an error like :
loginHelper.java:45: cannot find symbol
symbol : variable sqlHelper
location: class dbHelperBean.loginHelper
and when I include the package name in the call I get
loginHelper.java:45: cannot find symbol
symbol : class sqlHelper
location: package dbHelperBean
That's strange since the package of both classes is dbHelperBean and the class is indeed called sqlHelper. I tried to compile it in the same directory as sqlHelper as well. What am I doing wrong?
Thanks for any help.

TimestampOffset in FTP Adapter activation agent properties

Hi all,
I am having an issue using the "timestampOffset" FTP Adapter activation agent property on an SOA Suite 10.1.3.4/MLR#9 (Linux) system.
I have a BPEL process that is being launched via the FTP Adapter when a particular file appears on a remote SFTP server. I am polling for this file every 5 mins, and don't want to retrieve it unless it is at least 15 minutes old. The SFTP server from which I am retrieving this file is configured with a different timezone than the SOA Suite server on which the BPEL process is running; the SOA Suite server has a timezone of MST (GMT-7) and the SFTP server has a timezone of GMT. Here is the relevant section from the WSDL for this PartnerLink:
<jca:operation
FileType="binary"
LogicalDirectory="TriggerDirectory"
ActivationSpec="oracle.tip.adapter.ftp.inbound.FTPActivationSpec"
DeleteFile="true"
IncludeFiles="external_ids_trigger\.txt"
PollingFrequency="300"
MinimumAge="900"
ModificationTimeFormatOld="43,54,MMM dd yyyy"
FileModificationTime="DirListing"
ModificationTimeFormat="43,54,MMM dd HH:mm"
OpaqueSchema="true" >
</jca:operation>
I attempted to compensate for this by adding the "timestampOffset" property to the activation agent in bpel.xml (also included in the jdev_files.zip attachment); this is detailed in the document "Oracle Application Server Adapters for Files, FTP, Databases, and Enterprise Messaging User’s Guide 10g Release 3 (10.1.3.1.0) B28994-01". Here is the activationAgents section from the bpel.xml file:
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" partnerLink="PollForTriggerFile">
<property name="TriggerDirectory" type="LogicalDirectory">/uazsa/uazsaprd/integration/output</property>
<property name="portType">Get_ptt</property>
<property name="timestampOffset">25200000</property>
</activationAgent>
</activationAgents>
When deploying this BPEL project to the server, it shows the "timestampOffset" property for the JCA adapter in the log, as follows:
<2010-01-17 11:23:39,619> <INFO> <default.collaxa.cube.activation> <AdapterFramework::Inbound> JCAActivationAgent::initiateInboundJcaEndpoint - Creating and initializing inbound JCA endpoint for:
process='bpel://localhost/default/External_System_ID_Sync~1.0/'
domain='default'
WSDL location='PollForTriggerFile.wsdl'
portType='Get_ptt'
operation='Get'
activation properties={TriggerDirectory=/uazsa/uazsaprd/integration/output, timestampOffset=25200000, portType=Get_ptt}
However, this setting appears to have no effect, as when the adapter polls for the file, it finds it, but does not process it. I have turned up logging on default.collaxa.cube.activation to DEBUG, and I see the following when it polls for the file:
<2010-01-17 12:18:40,342> <DEBUG> <default.collaxa.cube.activation> <FTP Adapter::Inbound> Opening sftp channel

What needs to be done to have the timestampOffset property in bpel.xml honored by the activation agent? Any help is greatly appreciated! I have opened up an SR with Oracle on this as well, but sometimes the forums prove to be a quicker path to problem resolution. :)
Thanks,
--Gary

Thanks for the reply, Anirudh.
Can you elaborate? The last part of section A.3.3. in the URL you posted is exactly what I did...I specified the "timestampOffset" property to the activation agent properties in bpel.xml. I specified the offset as the time difference (in milliseconds): 7 hrs = 7*60*60*1000 = 25200000. The value they provide in that example is puzzling: 2592000000 would be an offset of 720 hours! Maybe I'm misunderstanding something about this property?
Thanks,
--Gary

Manual enabling and disabling of activation agent in active-active topology

For Active-Active Topology for Adapters we can deploy and run Oracle BPEL Process Manager and business processes on all nodes but only one adapter service is running at any given time. In case of failover we need to manually disable the Activation Agent on the failed node & enable the activation agent on another node.
One customer has the below queries. Could anyone help.
a)Is there any way to automate the process of enabling and disabling of activation agent in active active topology ie failover is auto-detected and enabling & disabling happens automatically?
b)What is the suggested clustering topology for BPEL from oracle
Regards,
Senthil

Customer tried the configuration given in the doc http://download-west.oracle.com/docs/cd/B31017_01/integrate.1013/b31005/life_cycle.htm#CIABHCFE
But after applying the changes they are getting the following error message: "Invalid activation parameter.Activation parameter Physical/Logical Directory has invalid value. Check the error stack and fix the cause of the error."
1. Why this error coming?
2. Also the doc said If the BPEL PM servers (JVMs) in the cluster are located across TCP/IP subnet boundaries, then it is necessary to add the attribute clusterAcrossSubnet=true. Can I have more details on parameter "clusterAcrossSubnet=true" (with an example preferred)

ORABPEL-09903: Could not initialize activation agent

Hi,
I have installed SOA suite 10.1.3.1.0
I am trying to deploy a BPEL process which does a Dequeue operation using Oracle AQ adapter. The deployment is giving me following error.
BUILD FAILED
C:\SampleWS\BPELApplication\SubscribeOrderForOracle\build.xml:79: A problem occured while connecting to server "10.48.233.135" using port "8888": bpel_SubscribeOrderForOracle_1.0.jar failed to deploy. Exception message is: ORABPEL-09903

An error occured while initializing an activation agent for process "SubscribeOrderForOracle", revision "1.0".
Has any one came across this error. I tried reading through few topics in this forum related to this error but could not get any resolution.
Any help is appreciated.
Thanks & Regards,

Hi And thanks for your reply.
Well I have recently installed SOA suite 10.1.3.1 release-3. Earlier I was working on 10.1.2.1.0 PM server and looks like there are lots of changes that have happened in the new release.
On the newly installed SOA suite I created a BPEL process (EnqueueOrder) and instructed in the Reference guide and I was able to queue a message to Oracle AQ on Oracle 9i database.
For dequeing I created another empty BPEL process (DequeueOrder) and instantiated the process with a Receive activity which inturn dequeus message from the above said queue and writes the message to a file using File Adapter.
I was trying to deploy DequeueOrder process and few a times it got deployed successfully but on testing it from the BPEL Console the receive activity was not responding with any message. It only showed a message saying "Received "Receive_1_Dequeue_InputVariable" call from partner "SiebelOrderSubscriber"" on the BPEL console.
Now again it has started giving the same error while deployment, saying ORABPEL-09903: Could not initialize activation agent. Anu clues.....?
I have one more question....Do I need to create a seperate jndi and DataSource in oc4j to point to my local 9i database and refer it in the AQ Adapter configuration wizard?
Thanks & Regards.

Adapter activation agent documentation

Where can I find documentation on configuring file adapter activation agents and the configurable parameters for the activation agents.
Thanks

Hi Clemens,
To take a step back, the overall goal is to process a large number of files and not have any one file dominate the processing activity. I would also like to look at the best practices to achieve this goal.
The current mechanism this is achieved is as follows:
Files are read from multiple directories. There is a program called the directory listener that batches the records in units of 100 reads these and places on a central queue. Then 100 are read from the second file, etc. and placed on a queue.
Once this is done there is a dequeue listener to dequeue and process records.
In terms of performance, if the files were read with multiple threads, having multiple files open and in batches of 100 (but not necessarily sequentially) do you think this might be more performant as opposed to reading them sequentially?
I am interested in looking at the best practice and the most performant mechanism to achieve the overall goal of reading a large number of files from different directories, processing them in batches and not having any one file dominate the processing.
Thanks for all your help. It is greatly appreciated.

Error while initializing activation agent for DBAdapter MasterDetail Demo.

God day,
following precisely the steps in Master Detail -Database Adapter sample.
- configured adapter and deployed project and everything looked fine.
- when start the Process Manager, always get:
( Error while initializing an activation agent for process "DB_MaterDetail"
PLease ensure that the activation agents are configured correctly in bpel depolyment descripto bpel.xml. oracle.tip.adapter.fw.agent.jca.JCAActivationAgent: java.lang.reflect.InvocationTargetException.

but it did not help.

Mail activation agent in 11g

Hi,
I used to implement mail activation agent in 10.1.3.4...
But I couldn't find a section of it in 11g. Anyone has pointers on this?
Thanks.
Sri

Thats nice,
The User Messaging Service could then be used to configure incoming actionable mails. But I need to listen to multiple email servers. Is this possible to achieve this using UMS ?
To put it simply, I need to instantiate a composite after the emails are being polled from the email server.

Jca Activation Agent error

Hi,
I am trying to deploy a process to the BPEL server which uses a FTPAdapter to get a file from a server, and bring it into the BPEL process. I have defined my "eis" entry in the oc4j-ra.xml file in the application-deployments/default/FtpAdapter folder. I have restarted the server after this configuration change. The process deploys from Designer without giving any errors in Designer, but when I view the deployed process in PM, it is flagged with an error. The error message it gives is:
The following exception occured while loading this Process:
Exception Name:
Could not initialize activation agent
Exception Description:
BPEL container could not initialize activation agent class "oracle.tip.adapter.fw.agent.jca.JCAActivationAgent". The reason is Unable to obtain Locator handle. The Adapter Framework Message Listener was unable to obtain BPEL Process Locator handle: Authentication failed. Failed to authenticate credentials. Please examine the log file to determine the problem. .
Suggested Fix:
Please ensure that the activation class "oracle.tip.adapter.fw.agent.jca.JCAActivationAgent" is configured correctly in the bpel deployment descriptor (bpel.xml).
Context:
Stack Trace: Does anyone have any ideas as to why this is happening?
Thanks

Could you please send me [[email protected]] your bpel.xml and oc4j-ra.xml for investigation.
It seems to me that there are some mismatch between them.
Thanks,
Rakesh
