Event Callback for JTS managed transaction.

Dear all,
We would like to implement some logic at the pre/postCommitTransaction callback method. However, we worry if the transaction is managed by JTS, this event will not be raised when JTS commits the transaction.
Thanks and regards,
William

Dear Ailitche,
Thanks for your suggestion. I am looking at the source for Oracle9iJTSExternalTransactionController and Oracle9iJTSSynchronizationListener.
// at Oracle9iJTSSynchronizationListener
public void beforeCompletion() {
unitOfWork.issueSQLbeforeCompletion();
unitOfWork.setPendingMerge();
getSession().incrementMergesPending();
Will these three lines of code trigger the preCommit event for UnitOfWork?
Similarly,
// at AbstractSynchronizationListener
public void afterCompletion(int status) {
if (wasTransactionCommitted(status)) {
unitOfWork.afterTransaction(true, true);
} else {
unitOfWork.afterTransaction(false, true);
Will unitOfWork.afterTransaction() trigger the postCommit event for UnitOfWork?
Thanks and regards,
William

Is there any event callback for "pre/post-register/unregister" object?

Dear all,
We noticed that there are rich set of event callback provided by TopLink, including "pre/post-Refresh/Build/Clone/Merge". However, we cannot found any callback method for "pre/post-register/unregister" events. They will be very useful, if we to manage the internal status of register/unregister to indicate whether it is still under the control of TopLink.
Thanks and regards,
William

William,
Those specific events do not exist. The postClone event is called after an object is registered. This is frequently used to copy non-persistent values from the cached original into the working copy.
There is also the ability to customize the clone/copy policy used by TopLink in creating the working copies in the UnitOfWork.

Bean-managed transaction with EJB 3.0

Hi,
I try to get a bean-managed transaction example running with EJB 3.0 under GlassFish v2ur2.
In order to demarcate the scenario I have to get me the UserTransaction which I get from the SessionContext. I would like to use it then like: UserTransaction ut = context.getUserTransaction();
I tried to get the SessionContext with the help of the EJB method setSessionContext which should be called by the container after instance creation.
However, setting a log output into that method does not show any call of this method.
So, how can I get this method called or is there another way to get the SessionContext for the UserTransaction to work ?
Are there any good and fully implemented examples for bean-managed transactions ?
Thanks for your help.
Regards

I found the solution for that my SessionContext was NULL and I could not use the UserTransaction.
The reason for it is that I injected the EJB with @EJB into my servlet and did a MyBean mybean = new MyBean();
That leads to a SessionContext which is NULL within my EJB.
If I use it without instantiating it it works fine.
Again, thanks for your help. At least it pointed me into the right direction.
Regards

Basic Transaction Codes for RailCAr Management

Hi,
I am looking for some basic Transaction Codes for Rail Car Management especially loads and unloads.
Anyone please?
Regards

Hello Shirley,
I assume that you are using either Event Management to collect the load/unload events OR your manually entering this data onto the Freight Unit?
If the answer to the above information is correct, then it would depend where you are storing this data. Are you adding the data to the Freight Orders or to the Freight Units? If you are using FOs then some of the fields might be present on the FO work list and you could create a query/view there to view this data. There is also a work list on the FWO side but it would only contain a summary of the FUs. That is due to the one to many relationship between FWOs and FUs.
You might be better off building an ALV report to gather the fields that you need. Alternatively this could be done in SQVI but it is more limited.
An alternative to all of this if your using Event Management, is that you could produce a report in EM to give you this information. This however would only be possible if you are sharing all of the info that you need in the report with EM.
Hope that helps
Devin

The stack trace is given below. This exception is occured at "em.flush()" method. I even tried removing em.flush() method. Even then I got the same exception.
I tried a different way of overcome this problem. Used UserTransaction instance say "ut" before create / modify the entity bean and later comitted. In that case I am not getting any exceptions. However, commit is happening only when new instance is created, commit works, but modification of an existing instance, commit is not working. Looks like there is some serious problem with EJB 3.0 in OC4J. Basic functionality is not working.

Hi All,
I am getting below error while inserting into Linked Server (sql2012) thru trigger from sql2008 ....However if i insert the same thru Store Procedure it is inserting successfully....MSDTC service is started on both sql server machines....also both machines
rebooted....but still i am facing this error.
OLE DB provider "SQLNCLI" for linked server "XXX.XXX.XXX.XX" returned message "The partner transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Procedure ins_test, Line 11
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "XXX.XXX.XXX.XX" was unable to begin a distributed transaction.
Could assist to resolve.

Shehzad

Hi SHzKhan,
According to your error message, we need to verify if you configure the MSDTC correctly, When you have more than one SQL Server involved in a Distributed Transaction, you need to make some changes to the default configuration of MSDTC for these distributed
transactions to succeed. There is a detail about recommending MSDTC settings for using Distributed Transactions in SQL Server, you can review the following article.
http://support.microsoft.com/kb/2027550/en-us

ViInstallHandler for event callbacks issue

My app register callbacks for two events IO_COMPLETION and SERVICE_REQ (two viInstallHandler calls one after other). This perfectly works with the old version GPIB version 1. and VISA 2.1 but do not work with VISA 2.6.1 and GPIB driver NI488 2.2.1.
However, if my application only registers for IO_COMPLETION, the call back function is triggered after viWrite for command "*IDN?\n".
What needs to be done if both of the events to trigger the callbacks in a session?

Please verify which NI-488 version you have - do you mean that you have NI-488.2 2.1? (I don't think that 2.2.1 exists.) If my guess is correct, you should upgrade to NI-488.2 2.2 at www.ni.com/downloads. There were some fixes related specifically to this bug.
While you're at it, I suggest upgrading to NI-VISA 3.1. There have been a handful of GPIB-related bug fixes in that upgrade as well.

Event handler for BTOrder Save

Hi,
At the moment I'm building a new component for the BTOrderHeader. For the creation of this method I followed the wiki page: [Extend BOL Model BT with custom table type relationship|http://wiki.sdn.sap.com/wiki/display/CRM/ExtendBOLModelBTwithcustomtabletyperelationship].
I personally have some problems with the Event Callback events, why can't the save handling be done in the GenIL RUN_BTIL class itself?
As reference for my question:
When I enhanced the Business Partner, I used the CL_BUIL_ABSTR class as superclass. Then in the maintenance method, I can call the REGISTER_SAVE_HANDLER, so the method EXECUTE_WITH_SAVE is called. For a Business Transaction, this process is totally awkward when you know this nice manner of the extending the BP. Or am I missing something in the possibilities of the CL_CRM_RUNTIME_BTIL?
Hope some guys can tell me a nicer solution for new custom BT GenIL components.
Thanks!
Best,
Sander

The use of the callback events does enable you to extend the functionality of your new BOL-entity very easily.
That might already be a reason to use this way of working.
Kind regards,
Ruben

Event handler for STDIN input?

Hi,
This question will probably require a bit of context - I'm attempting to re-implement in java an application that's currently written in perl. The application is a server helper app that rewriters urls; it receives a request ID and a URL on stdin, does the necessary munging (which can require an external SOAP query), then returns the resulting rewritten URL.
Since the results can be asynchronous due to the need for external queries to build the result, this is currently a multithreaded perl app implemented using perl's POE framework to register an event handler for stdin. That handler fires each time a line of input is received, then feeds the query to a thread pool manager (POE::Component::Pool::Thread, which is conceptually similar to the Executor frameworks). The thread returns the result as a callback registered to another function in the main thread, which then populates the query/result to a cache then outputs the result (with the original query ID) on stdout. Since stdin input and the result callbacks are event-driven, there's no while(true) main loop or other blocking mechanism in the main thread. Unfortunately, it's perl-ness is causing problems due to perl's threading implementation (three words: "copy on init"), so we need to reimplement in a language with a more robust threading implementation (preferably one with copy-on-write for shared objects). So, Java it is.
So far everything's been good - Executor, Callables, and Futures work as I hoped they would for proper thread management, and the internal worker thread logic (XML processing, SOAP, regular expressions, etc) is proving rather simple to adapt. However, the main roadblock I'm hitting is that so far, I have not found a way to register any sort of event handler for STDIN input (or more specifically, InputStreamReader/BufferedStreamReader events). This could be due to search engine pollution - everything I see when I search for documentation on event listeners appears to be GUI-specific (buttons, menus, text areas/forms, etc). I'm just looking for a way to handle a line of STDIN, not a text area on a form.
Any pointers in the right direction will be much appreciated!

rekoil wrote:
Maybe I need to rethink the design here...
The main reason I used a callback in the original perl is that there's a large cache structure that gets checked before the thread dispatch, and only cache misses get pushed to a thread for processing. Callbacks from the threads will then add its results to the cache. Thanks to perl's thread model, when I attempted to make the cache a shared structure - in perl, you have to explicitly mark as "shared" variables that you want visible to all threads - the structure wound up getting copied to every thread, and this gave the app an unacceptable memory footprint. So the solution was to use a callback in the main thread to update the cache.
I'm now thinking that if Java's thread model is a bit saner (i.e. a shared object doesn't get copied into every thread), then I could just have each thread update the cache, print its output to STDOUT directly, and avoid the need for the callback. I can then make my input loop simply a while() loop, waiting for the next input to dispatch. Sound sane?Yes I think so.
There is some of this I still don't entirely understand. Your loop sounds better now but it sounds to me like the process is this.
1) read from in
2) call some stuff on the basis of what came in
3) do work
4) workers produce things
5) things written back out
6) read back in??
If you're just going in/out then great. If you are going in/out/in then maybe some sort of PipedInput/Output Streams? It may well be that I got lost in your explanation in which case never mind.

Event creation with status management

Hello esteemed gurus ... it's your friendly workflow noob again
It seems once people get a sniff that there is a someone who knows a bit about workflow in the company, everyone wants a piece of you!
So... I have been asked to setup a workflow that will trigger when a user changes a user status on an SD contract. I've done some reading and I believe I'm nearly there but need a little help ...
I have setup event creation with transaction BSVZ for object category VBK, specified my status profile, and business object BUS2034 and I'm using the event "CHANGED", within this I have set a status restriction to particular status of my user status profile.
In my workflow definition I have specified the start event "CHANGED" for my business object BUS2034.
The thing is, the workflow starts for every change to the contract, whereas I was expecting it to only start when the particular status I defined in my status management was set in the contract header.
Are there any additional settings I need to make in order to restrict the starting conditions of the this workflow?
Many thanks once again.
Neil

Hi Neil,
There is two options to restrict the workflow.
First one is start condition. You can check the workflow log. If your required field is populated in the Workflow container you can use start condition to restrict the workflow. In the Basic data of workflow template, Start condition is there. You can use the condition editor to set the condition.
If your field is not populated by default, then you can use check function module for this. You need to create one FM, and in transaction swe2, the FM needs to be Configured. The concept is, based on the Sales document number you can get the required field and check the condition inside the FM. If the condition satisfied just leave it. The workflow will be triggered. If the condition is not satisfied raise a Exception. So that the Workflow will not be triggered.
Thanks,
Viji.

Executing SQL statements in container managed transactions

I have a problem when using TopLink 9.0.3 with WebSphere 4, Oracle 9i and J2EE container managed transactions.
The data changing SQL statements are executed at the end of the (container managed) transaction, not at the time of the calls to UnitOfWork.registerNewObjekt(),
UnitOfWork.validate...() or UnitOfWork.commit...().
UnitOfWork(2035008996)--validate object space.
UnitOfWork(2035008996)--validate cache.
UnitOfWork(2035008996)--JTS#beforeCompletion()
UnitOfWork(2035008996)--Connection(398132708)--INSERT INTO SVM_PERSONEN (FAX, NAME, ID, [...]) VALUES ([...])
UnitOfWork(2035008996)--JTS#afterCompletion(org.omg.CosTransactions.Status._StatusRolledBack=4)
UnitOfWork(2035008996)--release unit of work
But the end of the transaction is out of the application server code. The transaction ends after the invoke of the applixcation server method, as the stack trace of an occurring exception shows:
remote exception
javax.transaction.TransactionRolledbackException: CORBA TRANSACTION_ROLLEDBACK 0 No; nested exception is:

So the application server code has no possiblity for special reaction to this error condition.
How can I use TopLink to execute my SQL statement immidately, not at the the end of the transaction (which is out of the area of my code)? Only the transaction should end at the usual time, managed by the container.

I don't think there is anyway to currently do this in a JTS managed environment, to handle the exceptions you could,
- Make use of TopLink session ExceptionHandlers to handle the database errors during the JTS commit.
i.e.
uow.setExceptionHandler(yourExceptionHandler);
or,
- Let TopLink control the transactions instead of JTS.
