Transaction Context Propagation

Can transaction context be propagated from one WebLogic Server to another? If yes, what is then the relationship between the two Transaction Managers in each server?

Zhenxin,
          Transaction can be propagated between multiple instances of the server.
          In releases 5.1 and below, all databse access in this case was delegated to 1 jdbc connection in 1 pool on 1 server, and the database transaction manager was used.
          In 6.0 and above, the transaction is co-ordinated by the TM in one instance of the server, which calls on the remote instances during the pre-commit and commit phases.
          I believe that currently the 1st server to be invoked in the transaction is the one who gets the commit responsibility, but this is an implementation detail that may
          change in future.
          I hope that helps.
          Regards,
          Peter.

Transactional Context Propagation

Hi,
          Suppose that I a statefull session bean that uses a helper class to delegate
          its business methods. If the transactions are demarcated from the container
          will the transactional context of the caller (of the helper class) method be
          propagated to the helper class?
          Thank you in advance


          Hi,
          Is this true also for BMT? I have a problem where the UserTransaction
          object seems not to propagate from one BMT bean to another BMT bean.
          At least the status of the transaction
          (as retrieved by this.sessionContext.getUserTransaction().getStatus())
          is Status.STATUS_NO_TRANSACTION when checked in the method of th called bean.
          regards - Johan

Send message in a non-transactional context

I've coded a simple Log4j appender to send error messages to a queue (JMSAppender provided by Log4J is not good for me because it use a publish/subscrive model and use topics instead of queues); the appender has to work in a non transactional context, so the appender has to send always the message to queue although the global transaction rollbacks; I've create queue session settings transacted parameter to false and acknowledgeMode to AUTO_ACKNOWLEDGE , but message is not delivered to queue if the global transaction, started by an EJB Stateless Session Bean, rollbacks; in my environment (IBM WebSphere and IBM MQ), queue connection factory is configured no-XA resource.
Any suggestions?
Below the source code.
Thanks in advance
context = new InitialContext();
queueFactory = (QueueConnectionFactory) context.lookup(getQueueConnectionFactoryBindingName());
queueConnection = queueFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false,Session.AUTO_ACKNOWLEDGE);
queue = (Queue) context.lookup(getQueueBindingName());
queueSender = queueSession.createSender(queue);

Transactional Context

hi guys
Have a quick question on transactional context
Question:
Will the transactional context be passed on from a LSB mediator to other java
components (simple java classes).
The LSB is delgating control to managers which are simple java classes. These
managers are inturn executing sql queries. We need that the LSB and the simple
java class execute within the same transactional context. i.e if the manager throws
an exception, the LSB should roll back all the previous sql statements. The manager
doesnt do any transaction management (by retrieving UserTransaction) and simply
executes the sql calls.
Do you think that these calls will be covered by the same transaction context.
thanks for your time

Using oracle's connection pools and transactional context

Hi!
I have an implementations of existing interfaces ( let's call this layer as
data access layer) which abstracts the connection and transactional session
from the calling application. This implementaion makes use of Oracles JVM
inside the oracle database (8.1.7) to create and maintain the connection
pools and the transactional session (transactional context). I would like
to create differenent implementation, if the calling application is a
session bean running inside the weblogic application server. is there way I
can still use the connection pools and transactinal context that I got from
the oralce if the calling application is a session bean running inside the
weblogic app.. server?
do I have to change any configuration settings in weblogic?. there might
be two scenarios..
the data access layer (the classes which deal with the connection pools and
transactions) might be running inside the oracle's JVM..
the data access layer might be running inside weblogic application server...
thanks...

XA datasource autocommit is false when no transaction context

WLS 8.1SP4
I am usign MS SQL Serevr JDBC driver.
I use the XA driver: com.microsoft.jdbcx.sqlserver.SQLServerDataSource
I have an MDB, transaction not supported.
The MDB gets a connection from an xa datasource which maps to that SQL Server XA driver.
Even thogh the txn is not supported, autocommit is set to TRUE in the connection. I want it false. I know that I can use a non-txnal DS, but why is autocommut false when I have transaction context?
Kind Regards,
Graham.

How to execute a commit and wait via bol transaction context?

Hi All,
Currently a service contract is created via bol objects.
Once all the objects are created, the modify() method is called bol_core instance.
After that, the bol transaction context is assigned and the save() and commit() methods are called.
This works fine, but the commit does not wait for the database to be updated before moving to the next steps.
How can i get something like the 'commit work and wait' statement via the bol transaction context?
would a commit work and wait statement work the same?
regards,
Leng

Hi,
It is a CRM specific issue.
so the code sniplet is:
go_bol_core = cl_crm_bol_core=>get_instance( ).
go_bol_core->load_component_set( 'BT' ).
create factory for BTorder
go_bol_factory = go_bol_core->get_entity_factory( 'BTOrder' ).
gs_param-name = 'PROCESS_TYPE'.
gs_param-value = 'ZSC1'.
APPEND gs_param TO gt_param.
go_btorder ?= go_bol_factory->create( gt_param ).
send changes
go_bol_core->modify( ).
go_transaction_context = go_btorder->get_transaction( ).
    lv_success = go_transaction_context->save( ).
    IF lv_success EQ abap_true.
      go_transaction_context->commit( ).
so after the commit, it does not commit to the db straight away.
i asked a collegue, and i got this:
Using the BOL commit should perform the commit in one of two ways u2013 depending on the how the application (i.e. the GENIL layer has been implemented). It will either do a commit work and wait, or use a local update task and commit work statement. So based on this the update should be synchronous i.e. it should wait for the update to finish. In the case of the one order transaction it basically runs the update in local task.
Basically i don't understand why it is behaving as it is.

Passing transaction context to weblogic container

I am developing a java application which is doing some database
updates. It invokes a few EJBs deployed on weblogic server 4.5. Those
beans also do some database updates. I want all the database
operations in a single transaction. The beans are configured to be
bean managed transactions and use weblogic connection pool (weblogic
pool driver)
I want to create a transaction context in the java application and
also want to make EJBs participate in the same context.
Is this really possible to achieve?
Thanks
Jagdish

Hi Bob,
In TestStand 3.0 and later you can pass the sequence context as a CAObjHandle in CVI. The easiest way to get an example of this is to create a blank sequence and insert an Action step. Right-click on the step and select specify module. On the module tab specify a name for the function. Next on the Source Code tab click Create Code... This will prompt you for a location and name for a project file and a c file. It will then create code for you that demonstrates how to pass the sequence context and use it.
If you're using an older version of TestStand then the parameters you can pass are fixed. I would suggest looking at one of the shipping examples. The Register step in the following example demonstates how to pass the sequence context and use it: C:
\Program Files\National Instruments\TestStand 3.1\Examples\Demo\C\cpu.seq
(This path will be different depending on your version of TestStand.)
I hope this helps!!

IllegalStateException - SSB loosing transaction context

I have a following scenario
1. MDB1(txn not supported) calls SSB1 (txn att = required)
2. SSB1 calls some other SSBs and Enity beans with txn attt = required.
3. SSB1 catches checked exception and calls rollback
catch ( MyCheckedException e){
this.getSessionContext().setRollbackOnly();
throw e;
Note that setRollbackOnly() is called from SSB1 which is in transaction but still
I get following error on weblogic console that setRollbackOnly() is called from
a bean which is not participating in transaction. This behavior is not consistent
it happens some time. I re-started the server and weblogic started executing txns
properly.
My question is when a pair of MDB and SSB is used does SSB LOOSES it's transaction
CONTEXT in some situation?
I would really appreciate and early help as it is critical for the project
thanks

BContext.setRollbackOnly() from an EJB that was not participating in a transaction

Deyan,
I assumed that Saurabh's statement that SSB1 has Required attribute is true.
The Spec says:
"17.6.2.8 Handling of setRollbackOnly() method
The Container must handle the EJBContext.setRollbackOnly() method
invoked from a business method executing with the Required, RequiresNew,
or Mandatory transaction attribute as follows:
- The Container must ensure that the transaction will never commit.
Typically, the Container instructs the transaction manager to mark the
transaction for rollback.
I'd guess that TX gets rolled back as soon as control returned
to the container from dispatched method called setRollbackOnly().
As you can see, the Spec allows it and it does make sence
taking in account cost of holding TX.

"Deyan D. Bektchiev" <[email protected]> wrote in message

Slava,
According to the EJB spec the transaction should not end just because at
some point it was marked for rollback, only that it should never commit.
The EJB should still be able to call setRollbackOnly without any problems.
It look more like the transaction context is either never created or
lost somehow.
And if there is no transactional context
SessionContext.getRollbackOnly() will throw the same exception (EJB 2.0
Section 7.6.1 for stateful and Section 7.8.2 for stateless session EJBs).
So I'd start by making sure that the EJB is not marked with BMT and
"Required" TX attribute -- in that case the EJB will use BMT and the TX
attribute is ignored.
Another way to see that there is a transaction is to use
System.out.println(weblogic.transaction.TxHelper.getTransaction); to
print the current transaction and verify that there is actually one.
Regards,
Dejan

Hi Saurabh,
It could happen because by the time SSB1 received the exception the TX

been rolled back already.
The code in the catch block should look like the following:

this.getSessionContext().setRollbackOnly();

OSB Transaction context (QoS exactly once)

Hi all,
First of all, excuse me my poor english...
I need to understand how develope transactional services with OSB.
My unit test are 2 proxy services : first with JMS/XA transport (with response requiered) with 2 Service Callout to transactional EJB with exactly once; second proxy routes the first with HTTP transport with exactly once.
When services ends ok, or i reply with error in error pipeline, commit is executed; but if services failed, services no reply nothing until timeout proxy....then rollback is executed....
In conclusion, i don't know how i develope transactional proxy services....i choose bad transports?, i don't understand pipelines?...i'm very confused...
Thank you all

Hi,
i tested it without test console with no different results...and test console show me :
Response Data :
<con:metadata xmlns:con="http://www.bea.com/wli/sb/test/config">

</tran:headers>
<tran:response-code xmlns:tran="http://www.bea.com/wli/sb/transports">1</tran:response-code>
</con:metadata>

</con:fault>
Always i try to route (tunneling http) with exactly once to proxies JMS/XA, if proxy throws exceptions, in http proxy i see this : "JmsAsyncMessageTable timed out message"....
I'm disoriented...
Thx you very much.

Security Context Propagation between Managed Servers

          I'm using WLS 8.1 SP2. I have one domain, two managed servers, each on a separate
          hardware server. Each managed server hosts a different web application. I want
          to authenticate to Web App "A" and be able to invoke Web App "B" (from "A") without
          having to re-authenticate. Is this possible via configuration and, if so, how?
          Thanks.


Frank,
You do not have to do anything to propagate identity between the two
containers. As long as the user is authenticating first..
There have been a number of issues with the propagation, so be sure to stay up
on the service packs.
HTH.

How do you propagate security context information from Servlet to
EJBs? I have an web app that uses the container's FORM based authentication.
The servlet resource then calls a session EJB (w/ security contraints
setup). The webapp and the ejbs are bundled into one EAR.
Thanks!--

Using TxDataSource outside a transaction context

I have two questions about using TxDataSource:
- Can I use a TxDataSource outside a transaction? i.e. can I get a connection
from a TxDataSource if there is no active transaction?
- If the answer to the above question is true, do I have to close the connection
after I'm done using it? The data source is defined on a regular connection pool.
Thanks

.As far as the closing the connection goes, what do I do if I have multiple ejbs participating in
a transaction, and each one uses the connection from the database (the same connection, as they
are all participating in the same transaction)? Does each ejb method (assuming a session ejb with
REQUIRED transactional method) have to do a connection.close() before the method exits? Or in this
case, will the container automatically release the connection back to the pool when the
transaction commits or rollsback?We have you covered. Any time your code gets a connection from a TxDataSource in the context of
a transactional EJB, or in a servlet with an ongoing UserTransaction, we will cheerfully ignore if
your
code calls commit() or close(), because our Tx coordinator is the only one who knows when to commit.
Closing the connection is irrelevant to the flow either, because even though several EJBs in a given
transaction
all ask for a connection, and all get their own Connection object, these objects are wrappers around
a single
real pool connection, and if you close one wrapper, we know not to do anything with the underlying
pool
connection.
In summary, if you always stick to the basic standard of clean safe JDBC code, it will always
work,
and it is important to do so in a non-transactional state:
myJdbcMethodsLookLike()
Connection c = null;
try {
c = getConnection();
do all the JDBC
c.close();
c = null;
catch (Exception e) {
do whatever
finally {
if (c != null) try {c.close();} catch (Exception ignore){}
