ECC-6.0 supports XA(Distributed Transactions)&WS-AT(Web Services u0096 Atomic)

Hi
1- Does SAP ECC-6.0 support XA transactions?
XA Transactions stand for (Distributed Transactions).
2- Does SAP ECC-6.0 Web services allow participation in WS-AT?
WS-AT Stands for is Web Services Atomic Transaction specification.
If so please provide the referral point where I can get the Documentation regarding this.
Any earlier reply will be rewarded.

Hi
1. What is meant by XA ?? Please clarify.. I guess, ECC should support..
2. Yes...
SAP supports ATS... Atomic Transaction specification defines protocols that is recognized by SAP. This failure atomicity property is supported by atomic transactions, which have the following familiar ACID properties.

Database transaction management in Web services

Hi,
I am using Oracle8i and firing some database queries from my web services. I want to do the transaction management for the same i.e. When one of the queries fail, i want to rollback. But when i write my own transaction management, it gives me an error :
java.sql.SQLException: Cannot call Connection.commit in distributed transaction.Transaction Manager will commit the resource manager when the distributed transaction is committed.
Can anyone please help me out as to how to perform the database transaction management in web services.
Thanking in advance.
Prashant

Unfortunately to manage transactions over web services there is no viable solution available in market. All implementations come with restrictions e.g. Metro works with only EJBs on Glassfish, JBossTS works on JBoss but not with JAX-WS, Atomikos supports only Axis as of now.
1. See explanation above.
2. Yes, it can be but conditions mentioned above are applied :-)
3. [www.oasis-open.org/committees/ws-tx/|www.oasis-open.org/committees/ws-tx/]
4. Unfortunately as of now I do not see an easy way to this problem.

Adding transaction layer to Web service API

Our company, an ISP, recently invested in the BroadHop Enterprise Service Manager platform. The platform enables us to provision Internet services via the Web. We were able to write, largely from scratch, a "registration process" by which our users subscribe to service, and then sign-in to use their Internet access.
To create the data representing these new customers, the registration process utilizes several Web service APIs provided by BroadHop. There is one Web service to create the customer's account, another to provision his/her services, and another to facilitate the authentication process.
What I am interested in is a means of creating a transaction for these Web service calls, with the intention of "rolling back" in the middle of the process. The Web services are consumed thusly:
1. User enters data into session beans via a JSP-driven, multi-page, collection phase.
2. The data stored in those beans is disseminated into a special "bean" used to represent the customer's account information. This bean object is then submitted through the Web service API to create the account.
3. The data stored in the session is further disseminated into a product subscription object, which is then submitted through its own Web service.
4. Upon success returned by both Web service calls (the absence of an exception), the user is taken to the sign-in page.
If an error is thrown between steps 2 and 3, our present handler dumps all session data into an XML file and forwards the user to an error page. Although we could eventually automate the process, the data in the XML dump is then manually inserted into the system. Until this is done, however, the data stored in BroadHop is somewhat corrupt, because an account exists but is an orphan (without product subscription information).
What I am looking for is a generic means of representing the entire transaction as it is to take place, and programmatically "resuming" or "rolling back" the transaction so that orphan data does not hang around in our system.

My mistake...

void createPropertiesFileOnVirtualMachine(java.util.Properties props, VirtualMachine vm, java.lang.String propFileName)seems to do what I need...
Now, because my test environment only allow PV Guests, I'd like to know if that also work for HW Guests?

Support for xs:date types in web services generated from EJB components

I need to generate a Web Service from an EJB session bean based upon EJB entities generated from the Oracle 11g database that contain DATE type columns.
JDeveloper creates java.sql.Timestamp types in the EJB Session bean and this results in an exception error when I try to generate a web service from this bean via webservice annotations:
java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
java.sql.Timestamp does not have a no-arg default constructor
I expected the web service wizard to generate argument types xs:dateTime or xs:date so this was an unwelcomed surprise.
I tried manually adding a method to the session bean with java.util.date arguments and had no problems with the web service wizard that correctly created xs:dateTime arguments. Is there any particular reason why the EJB wizard does not generate java.util.date arguments or handle java.sql.Timestamp without failing with an exception?
Since I begin with database tables and generate EJB entity classes and then web services with the Jdeveloper wizards it seems to me that there is a problem here in JDeveloper. Would you agree?
There are several possible more or less appealing workarounds, such as doing manually adding methods to the EJB facade with java.util.date arguments and doing the conversion from/to java.sql.timestamp manually. Is this a reasonable approach or does JDeveloper support date/time for Date columns in some other way that I have missed?
Very Grateful for any comments or suggestions.

ADF- Jdev11.1.1.6 Business Components supports distributed transaction ?

Hi ,
I'm using Jdeveloper 11.1.1.6 release 1 . How to implement distributed transaction in ADF business component level.
In my scenario i need to perform A Single transaction with two different database . I do need to role back both if either one fails (Distributed Transactions) . How could i achieve this in ADF business component. Does ADF has any built-in support for Distributed transactions.
Could anybody advice me .
Thanks in Advanced .

Thanks for your response !!! What is the best alternative i can choose to achieve Distributed Transaction in ADF Application , if there is no inbuilt support for it in BC?

Can oracle temporary tables be used with distributed transactions?

Hello,
Does anybody know if temporary tables are supported with distributed transactions?
We use a temporary table to store query results and see no problems when the JDBC driver (Type 2 or Type 4) is used with local transactions. The temporary tables are set for transaction-level data persistence (delete rows on commit).
When we switch to JDBC/XA driver we occasionally get ORA-14450 error (java.sql.SQLException: ORA-14450: attempt to access a transactional temp table already in use).
Many thanks...

I have been able to use temporary tables on remote databases, so I don't think that it is forbidden. Of course, I'm not using JDBC so that might be a problem.
The other thing that occurs to me is that you are doing something other than DML with the table e.g. trying to drop it. If that is the case you should re-read the documentation and remind yourself of the purpose of temporary tables.
Cheers, APC

Does BPEL Server have support "Web Services Transactions specifications"?

The Web Services Transactions specifications define mechanisms for transactional interoperability between Web services domains and provide a means to compose transactional qualities of service into Web services applications.
Have anyone can explain oracle process manager have any support about "Web Services Transactions specifications" ?
or oracle BPEL process manager how to coordinate the actions of distributed applications. Such coordination protocols are used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed activities.
appreciate any idea for this issue, thanks a lot.

You have a number of options. You can use the built in Screen Sharing application, you can purchase Apple Remote Desktop for each user, you could look at 3rd party tools like GoToMyPC or if you are looking to replace Terminal Services look at AquaConnect.
The tool you use will be determined by what the users have at home. If they are also using Macs, they can use all the native tools. If they are on PC, they can use either a VNC client or many of the 3rd paty tools.

Distributed Transactions HA and DR

We have a few SQL Server environments besides Biztalk and its speciall HA and DR configuration(SQL Server failover cluster and Biztalk Log Shipping) that use distributed transactions. Is there a HA or DR solution that supports distributed transactions
other than failover clustering? I am aware that database mirroring is not supported for distributed transactions. How about log shipping or replication? Is there any official documentation on this?
Thank you in advance

Hello,
As Shanky post, there is limitation of distributed transactions when using database mirroring or log shipping. When using Microsoft Distributed Transaction Coordinator (MSDTC) transactions, the local transaction coordinator has a resource ID that identifies
the server on which it is running. When a mirroring or log shipping failover occurs, the principal database becomes hosted on a different server (the mirroring partner or secondary server), and so the resource ID of the transaction coordinator is different.

SAP provided web services in ECC 6.0

Hi all,
I need to consume some web services provided in <a href="http://erptest.esworkplace.sap.com/sap/bc/gui/sap/its/webgui">web services from workplace</a> (workplace user id needed to get access) from my ECC 6.0. I want to install these web services into my system.
1. How do I get these readymade web services into my system?
2. Do I need to install something for this?
3. If yes, where can I get the installable from?
Regards,
Ankit

Hi Ankit,
to add some more info to this:
- The services are coming in the form of an ERP 2005 Add-On
- Once you installed the add-on, you need to activate the services you wish to use in transaction WSCONFIG
- You can then test the services from transaction WSADMIN and start making use of them; in WSADMIN, you will only retrieve the services you have previously activated
Further tip:
- If you are not sure about which service you need, is always good to check the ES Workplace for getting information on each existing service
- In case you want to use the services in Visual Composer (always nice for quickly creating applications consuming services) you can refer to the following link:

This isn't a straight FORM Post as in the http binding support in WSDL. It posts
a soap message.
It's apparent that Workshop supports form-post and form-get.
But I dont see how it is done with straight WebLogic webservices. Does WebLogic
server read the web-services.xml or the WSDL file? I dont see a way to put in
http-post binding in the former and in the latter it seems to be ignored.
Can someone clarify.
Thanks.

How to control transactions (WS-AT) between two web services in OSB?

Could someone tell me if the OSB can have 2 diferents web services controlled by an unique transaction?
For instance: in the OSB there are two wsdl, each one with its own Business Service and ProxyService respectively. In my vb.net aplication I started a transaction, called the first web service succefully and from the second web service I got an exception. I expected the first web service undo its work because the vb.net aplication excute a rollback command. Is this possible? How can I do? Any sample or tip will be helpfull.
If I was developing without OSB, I would rely on WS-AT as shown in http://www.codeproject.com/Articles/38793/6-Steps-to-Enable-Transactions-in-WCF for two web services dot net, or for one web service dot net and other java, http://www.ibm.com/developerworks/websphere/library/techarticles/0707_lo/0707_lo.html.
My question is basically: Is still possible to keep a single transaction between multiple web services when they are mediated by OSB? If so, is there a example showing how?

Hi,
When you create the proxy server, you have to check "Transaction required" box on Message Handling page...

Disabling transactions from WLI Workshop Web Service application?

I need to disable the transactions from a Workshop generated Web Service for WLI (Workshop 8.1.6).
I can accomplish this by changing and repackaging the builded EAR-package by altering the ejb-jar.xml:s in the .workshop directory and setting the transactions from Required to NotSupported. It would be much more convenient, if I could do that change from the Workshop.
Actual question: is there a way to disable transactions from a Web Service in Workshop? I have not found any place to change this property.

Hi
You have 2 options.
As you mentioned you can modify the generated ejb descriptors. Unfortunately this attribute is not exposed as a property in the workshop, so you cannot change there.
Other option is to suspend the transaction created by workshop so that your webservice functionality or any control called within that won't be part of the workshop transaction.

Support Web Service structures

Hi,
A half year ago I got the following answer on a OSS message! The question was due to the missing support of Web Dynpro for a Web Service structure. The answer was this:
<i>Currently we do not support this feature.
A new Web Service Model implementation is planned to be released.
As design for this implementation is currently ongoing it is not
possible to make a final statement about the WSDL and XML schema
constructs which will be supported.</i>
My question is. Does anyone know more about this new implementation. When will it be released? Which schema constructs are supported? Any information is welcome.
Thanks
