XA Transaction Support In OC4J 10.1.2

Does OC4J support XA transactions using non emulated data sources? Or does 10.1.2 support XA transactions at all (across datasources-db or jms)?

The reason is that the commit coordinator lives in Oracle database for 10.1.2.x case. (you have to confiture the db link to do so)
In OC4J 10.1.3, the transaction manager has been re-implemented and the transaction coordination functionality is now located in OC4J, replacing in-database coordination, which is now deprecated. Also, the middle-tier coordinator is now "heterogeneous", meaning that it supports all XA-compatible resources, not just those from Oracle.
The middle tier coordinator provides the following features:
- Supports any XA compliant resource
- Supports interpositioning and transaction inflow
- Last Resource Commit Optimization
- Recovery Logging
-Frances

Local transaction support when BPEL invokes JCA adapter

Hi all,
I've implemented a BPEL process consisting of multiple invoke activities to my (custom) JCA Resource Adapter which connects to an EIS.
My concern is to support local transactions. Here are some code snippets describing what I've done so far.
Declare the transaction support at deployment time (ra.xml)
<transaction-support>LocalTransaction</transaction-support>Implementer class of ManagedConnection interface
public class MyManagedConnection implements ManagedConnection {
 public XAResource getXAResource() throws ResourceException {
 throw new NotSupportedException("XA Transactions not supported");
 public LocalTransaction getLocalTransaction() throws ResourceException {
 return new MyLocalTransaction(this);
 public void sendTheEvent(int eventType, Object connectionHandle) {
 ConnectionEvent event = new ConnectionEvent(this, eventType);
 if (connectionHandle != null) {
 event.setConnectionHandle(connectionHandle);
 ConnectionEventListener listener = getEventListener();
 switch (eventType) {
 case ConnectionEvent.CONNECTION_CLOSED:
 listener.connectionClosed(event); break;
 case ConnectionEvent.LOCAL_TRANSACTION_STARTED:
 listener.localTransactionStarted(event); break;
 case ConnectionEvent.LOCAL_TRANSACTION_COMMITTED:
 listener.localTransactionCommitted(event); break;
 case ConnectionEvent.LOCAL_TRANSACTION_ROLLEDBACK:
 listener.localTransactionRolledback(event); break;
 case ConnectionEvent.CONNECTION_ERROR_OCCURRED:
 listener.connectionErrorOccurred(event); break;
 default: break;
}Implementer class of LocalTransaction interface
public class MyLocalTransaction implements javax.resource.spi.LocalTransaction {
 private MyManagedConnection mc = null;
 public MyLocalTransaction(MyManagedConnection mc) {
 this.mc = mc;
 @Overide
 public void begin() throws ResourceException {
 mc.sendTheEvent(ConnectionEvent.LOCAL_TRANSACTION_STARTED, mc);
 @Override
 public void commit() throws ResourceException {
 eis.commit(); //eis specific method
 mc.sendTheEvent(ConnectionEvent.LOCAL_TRANSACTION_COMMITTED, mc);
 @Override
 public void rollback() throws ResourceException {
 eis.rollback(); //eis specific method
 mc.sendTheEvent(ConnectionEvent.LOCAL_TRANSACTION_ROLLEDBACK, mc);
}Uppon BPEL process completion, MyLocalTransaction.commit() is called. However, localTransactionCommitted(event) fails and I get the following error:
Error committing transaction:; nested exception is: weblogic.transaction.nonxa.NonXAException: java.lang.IllegalStateException:
[Connector:199175]This ManagedConnection is managed by container for its transactional behavior and has been enlisted to JTA transaction by container;
application/adapter must not call the local transaction begin/commit/rollback API. Reject event LOCAL_TRANSACTION_COMMITTED from adapter.Could someone give me some directions to proceed ?
My current installation consists of:
1. Oracle SOA Suite / JDeveoper 11g (11.1.1.4.0),
2. WebLogic Server 10.3.4
Thank you for your time,
George

Hi Vlad, thank you again for your immediate response.
With regards to your first comment. I already have been using logs, so I confirm that neither javax.resource.spi.LocalTransaction#begin() nor javax.resource.spi.LocalTransaction#commit()
is called in the 2nd run.
I think it might be helpful for our discussion if I give you the call trace for a successful (the first one) run.
After I deploy my custom JCA Resource Adapter, I create a javax.resource.cci.ConnectionFactory through Oracle EM web application and the following methods are called:
-- MyManagedConnectionFactory()
(Constructor of the implementer class of the javax.resource.spi.ManagedConnectionFactory interface)
-- javax.resource.spi.ManagedConnectionFactory#createManagedConnection(javax.security.auth.Subject, javax.resource.spi.ConnectionRequestInfo)
-- MyManagedConnection()
(Constructor of the implementer class of the javax.resource.spi.ManagedConnection interface)
-- javax.resource.spi.ManagedConnection#addConnectionEventListener(javax.resource.spi.ConnectionEventListener)
-- javax.resource.spi.ManagedConnection#getLocalTransaction()
-- MySpiLocalTransaction(MyManagedConnection)
(Constructor of the implementer class of the javax.resource.spi.LocalTransaction interface)
-- javax.resource.spi.ManagedConnectionFactory#createConnectionFactory(javax.resource.spi.ConnectionManager)
-- MyConnectionFactory(javax.resource.spi.ManagedConnectionFactory, javax.resource.spi.ConnectionManager)
(Constructor of the implementer class of the javax.resource.cci.ConnectionFactory interface)BPEL process consists of multiple invoke activities to my (custom) JCA Resource Adapter which connects to an EIS. Client tester invokes BPEL process, and execution starts.
Here is the method call trace for the last invoke (after which, commit is executed). The logs for all the rest invocations are identical:
-- javax.resource.cci.ConnectionFactory#getConnection()
-- javax.resource.spi.ManagedConnection#getConnection(javax.security.auth.Subject, javax.resource.spi.ConnectionRequestInfo)
-- MyConnection(MyManagedConnection)
(Constructor of the implementer class of the javax.resource.cci.Connection interface)
-- javax.resource.cci.Connection#close()
(I don't understand why close() is called here, any idea ?)
-- javax.resource.cci.ConnectionFactory#getConnection()
-- javax.resource.spi.ManagedConnection#getConnection(javax.security.auth.Subject, javax.resource.spi.ConnectionRequestInfo)
-- MyConnection(MyManagedConnection)
(Constructor of the implementer class of the javax.resource.cci.Connection interface)
-- javax.resource.cci.Connection#createInteraction()
-- MyInteraction(javax.resource.cci.Connection)
(Constructor of the implementer class of the javax.resource.cci.Interaction interface)
-- javax.resource.cci.Interaction#execute(javax.resource.cci.InteractionSpec, javax.resource.cci.Record, javax.resource.cci.Record)
-- javax.resource.spi.LocalTransaction#commit()I would expect that after the last commit() - meaning that BPEL process is done, and its state is "Completed" - Weblogic server would call the following:
javax.resource.cci.Connection#close()However it doesn't. Do I miss something ?

Is XA transactions supported for the SOA Suite 10.1.3.4 on weblogic platfor

There are 2 weblogic domains 1 & 2. Domain 1 hosts the JMS queue and domain 2 hosts the BPEL process. The BPEL process in domain 2 uses JMS adapter to get messages from domain 1. With queues on Weblogic domain 1, is XA transactions supported for the SOA suite 10.1.3.4 BPEL process JMS Adapter on weblogic domain 2?

CAF entity proxies provide Transactional support???

Hi All,
We have created entity services, generated proxies so that we can use them in our webdynpro component's. Question here is, does the Generated Proxies of entity services provide Transaction support? or do we need to move all the business logic from webdynpro to CAF Application service?
Appreciate your time
Som

Hi Aliksei,
Thank you for the reply back.
Here is the situation:
We are generating proxy classes for CAF entity objects and using them in WebDynpro for all our custom CRUD operations.
Is this a good design or move all the CRUD operations to App Service and call it in the webdynpro. What is the exact difference in Updating the CAF Database from WebDynpro (Component controller) and from App Service.
In what scenario's you use App Service and WebDynpro Component controller with respect to Updating CAF Database.
Thank you for your time.
Thanks

Just wanted to update with what I found out incase anyone else needs this information:
The SRE 505 eGate JMS Reference PDF file, indicates that SRE JMS is compliant with JMS version 1.0.2. In ICAN 505, the JMS server is compliant with JMS version 1.0.2b.
Also OC4j 10.1.2 adaptor is compliant iwth JMS version1.0.2b.

Enable Oracle XA Transaction Support

Hi everybody. First of all, sorry for my terrible English.
I've been some problems using COM+ with Personal Oracle 8i (8.1.7.0.0) and SQL Server 2000 and Windows 2000 for development only.
I have one method that inserts the same data both SQL Server and Oracle (the tables and procedures definitions are identical) and I'm utilizing GetObjectContext method to commit or abort the transactions (the COM component were made in VB). Out of COM+ environment the method works 5x5. The error message is: "-2147168229 - Cannot connect to the transaction manager or the transaction manager is unavailable."
Checking Microsoft documentation I found an article (http://support.microsoft.com/support/complus/mtsandoracle.asp) telling me to "Enable Oracle XA Transaction Support" so I could have transactional work with Oracle and COM+. OK, just fine.
Does anyone knows how could I manage it? I am not a DBA nor I know one (an Oracle DBA), but I shall explain to my team how program 2 phase commit between Oracle and SQL Server.
Thanks in advance, and forgive me the size of this "book". I should be shorter next time...

Vivek, thanks for the help.
I am utilizing these versions of Oracle Products:
Personal Oracle8i Release 8.1.7.0.0 - Production
With the Partitioning option
JServer Release 8.1.7.0.0 - Production
Net8 Client 8.1.7.0.0
Oracle Services for MTS 8.1.7.0.0
Oracle Provider for OLE DB 8.1.7.2.0
The provider I first tried was MSDAORA with no success and then ORAOLEDB with no success too.
But those entries in registry that you sent me were all with Microsoft dll`s. I will try again tomorrow and send you the results
Thank you again
<BLOCKQUOTE>quote:<HR>Originally posted by Vivek Raja:
Renato, firstly what is the interface you use to access Oracle from your COM+ components? If it is OLEDB which provider is in use - MSDAORA or ORAOLEDB? What are the versions in use 8.1.6 or 8.1.7? If you are using MSDAORA as the provider then you will need to add the following key to your registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI.
Under this key add the following registry string values:
OracleOCILib - oraclient8.dll
OracleXALib - oraclient8.dll
OracleSQLLib - orasql8.dll
If you are using ORAOLEDB as the provider install Oracle Services For MTS 8.1.7. The error you receive seems to point to the fact that the "Distributed Transaction Coordinator" Windows2000 Service is not running.<HR></BLOCKQUOTE>

Transaction propagation between OC4J to non-OC4J J2EE container

I have a OC4J instance 10.1.3.1 containing a stateless session EJB 2.1. This bean call another session EJB in Websphere EJB container. The call goes through but the transaction is not distributed, meaning I cannot roll the transaction back from the OC4J container.
I have tried all kinds of context factories but it doesen't work. I use a XA datasource to an Oracle DB from the Websphere container.
Does anyone know how to propagate transactions from an OC4J container to another J2EE container:
Thanks
regards
A Bastell

You can specify the JNDI properties in your JSP/Java Client to lookup the EJB if it's in a different EJB container than the one provided by the JSP container.

Transaction support for OracleAQQueue

How is it possible to provide transaction support on OracleAQQueue enqueue and dequeue?
As far as i can tell, the queue operations are implicitly committed - or maybe im overlooking something fundamental?!

You may set OracleAQEnqueueOptions.VisibilityMode and/or OracleAQDequeueOptions.VisibilityMode to "OracleAQVisibilityMode.OnCommit" and wrap Enqueue and/or Dequeue operation in a local transaction to get the desired behavior.

EJB testing out of container - Ejb3Unit + transaction support?

I want to use JUnit for some EJB testing and have been looking at EJB3Unit for this. But then I heard that transactions are supported, it this true? If not, good. If true, how do you solve this?

Hi Debu,
I searched OTN. I could not find the example you have mentioned. Every time I got the example for a very previous release of OC4J.
Please help me locate the example you are referring to.
Thanks

JSF 1.2 supported in OC4J (JDev 11g)

Override EJB 3 transaction interceptor in OC4J 10.1.3 possible?

Hi
I'm using OC4J 10.1.3 with EJB 3 container managed transactions. I need to override the default transaction interceptor to add some additionnal logic that needs to be aware that a transaction will be commited, and I don't see any other way to do this since normal interceptors are not aware that a transaction is about to be commited when the method exits. Is there a way to do that?
TIA
Eric

Anybody? Since I'm using Bean Managed Transactions, should the transaction context be propagated through each call? When I do the same kind of test with Container Managed Transactions I can see that the transaction propagation is working... I thought it is supposed to work in both cases, the only difference being that with BMT the bean itself is managing the transaction...
Please, any help would be greatly appreciated...
Eric

JCA: Sample Adapter Transaction Support

Hi guys,
Could anyone tell me the transaction level supported by Sample Adapter.In the code they are using SAPResourceAdapter to access the J2EE Thread Manager.But in the code it has given that it won't support Local Transaction or XA Resource.
So what is the Transaction level supported by Sample Adapter.
regards,
siva.

You have to distinguish between 1) the Transaction level support of the J2EE Connector Architecture (JCA) and 2) the internal usage of the J2EE transaction manager.
Ad 1) the XI docu says JCA resource adapters can provide all kinds of JCA transactions. The Adapter Framework does not use them. That's why the sample adapter uses NoTransaction.
Ad 2): The transaction manager has to be used for asynchronous processing (QoS Exactly Once). This is used for transaction management inside the adapter. For details see the sample adapter code or the Adapter Development docu http://help.sap.com/saphelp_nw04/helpdata/en/59/59d6409ff68631e10000000a1550b0/content.htm
