Transaction management of Workflow Services

Workflow services (TaskService) are not participating in BPEL/client transactions when called as SOAP services. Only the EJB client interfaces of workflow services are able to join the client transaction.
I tried 2 options with BPEL client. Set the element taskService/participateInClientTransaction in wf_client_config.xml to true and set the value of CONNECTION_PROPERTY.TASK_SERVICE_PARTICIPATE_IN_CLIENT_TRANSACTION to java.lang.String "true" in the map argument to WorkflowServiceClientFactory.getWorkflowServiceClient(..) but workflow service does not participate in transaction with BPEL client.
Any idea how to make the workflow participate in transaction with BPEL client?

you can control from BPM.
COMMIT Acknowledgement is needed from the receiving system to control the adapters.

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.

Transaction Management using JDBC service

In Adobe Livecycle 8.2 JDBC service do not provide exception handling.
How to start trasaction from client Java application running on another machine and pass it to customised process having JDBC service
Should transaction be started on client machine using JNDI lookup of Transaction manager of Livecycle application server
How to rollback transaction when Java application get error from EJB end point.

Hello Amit!
It is true that LiveCycle 8.2's JDBC service has on built-in exception handling. This has been remedied in 9.0 as there are now several exception types that can be handled.
If I understand correctly, your trouble comes with the lack of transaction management around the existing JDBC service within LiveCycle. To this I can only recommend that any SQL statements needing to be run with transaction management be done so within an executeScript service. I have, on many, many occasions, utilized this service to write some custom code using the Statement and/or PreparedStatement classes to handle any database interactions.
In addition to the above, it seems as though you would like to leverage the JNDI lookup capability of LiveCycle's JDBC service so you can specify a data source name as opposed to having to establish your own connection. This too can be handled within the executeScript service via custom code. As an example, the following code, when dropped in an executeScript service, will establish a connection to an Oracle database via JNDI lookup:
import oracle.sql.*;
import java.sql.Connection;
import java.sql.PreparedStatement;
import javax.naming.InitialContext;
import org.jboss.resource.adapter.jdbc.WrappedConnection;
import oracle.jdbc.OracleConnection;
InitialContext ctx = new InitialContext();
String sDataSource = "YOUR DATA SOURCE NAME HERE";
Connection conn = ((DataSource)ctx.lookup(sDataSource)).getConnection();
org.jboss.resource.adapter.jdbc.WrappedConnection oWConn = (WrappedConnection) conn;
OracleConnection oConn = oWConn.getUnderlyingConnection();
From that point forward, you can simply leverage the PreparedStatement and/or Statement classes for any statements.
Please do let me know if you have any questions.

How to re-register Workflow Service in workflow manager 1.0?

I am using SharePoint 2013 Management Shell to re-register my Workflow Service due the following error I am having in Sharepoint Designer 2013:
Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors: Cannot set unknown member 'CompositeTask.RelatedContentLinkListItemIntegerId'. HTTP headers received from the server - ActivityId: e8e6d4fe-2a4e-41df-a046-a88e93e89e27.

Problem is that I don't seem to have connection when it comes to indicate the WorkflowUri
Can this error be fixed in any other way?

First you have to clean up
The clean up process is pretty easy, but as always I warn you against making changes to your systems if you are unsure of
the repercussions of doing it incorrectly. Additionally, removing / un-registering Workflow Services can halt, break, etc Workflows in the Farm.
Un-register the Workflow Service for the site
Navigate to Central Administration > Security > Manage Trust
Highlight the row by clicking the anchor link, it doesn’t work like other row selections in SharePoint (rather annoyingly)
Click Delete from the ribbon
Repeat steps 2 and 3 until all the “unfriendly” entries (assuming you’re not already using some)
Enjoy the nice clean Manage Trust pane
Next register it again with below PS command
Register-SPWorkflowService -SPSite 'https://myhost/mysite' -WorkflowHostUri 'https://workflowhost:12990'

Cannot Start Workflow Service from Service Manager

Hello Professionals,
I have a problem with starting Workflow service from Service manager,
I have configured all the settings and connection to database was successful.
However, after closing the settings window and try to start the workflow service, i got "Cannot start Service; configuration is not correct or cannot connect to database"
What may cause this issue?
Thanks and Best Regards,

Hi,
Please check SAP note:

Coherence and EclipseLink - JTA Transaction Manager - slow response times

A colleague and I are updating a transactional web service to use Coherence as an underlying L2 cache. The application has the following characteristics:
Java 1.7
Using Spring Framework 4.0.5
EclipseLink 12.1.2
TopLink grid 12.1.2
Coherence 12.1.2
javax.persistence 12.1.2
The application is split, with a GAR in a WebLogic environment and the actual web service application deployed into IBM WebSphere 8.5.
When we execute a GET from the server for a decently sized piece of data, the response time is roughly 20-25 seconds. From looking into DynaTrace, it appears that we're hitting a brick wall at the "calculateChanges" method within EclipseLink. Looking further, we appear to be having issues with the transaction manager but we're not sure what. If we have a local resource transaction manager, the response time is roughly 500 milliseconds for the exact same request. When the JTA transaction manager is involved, it's 20-25 seconds.
Is there a recommendation on how to configure the transaction manager when incorporating Coherence into a web service application of this type?

Hi Volker/Markus,
Thanks a lot for the response.
Yeah Volker, you are absolutely right. the 10-12 seconds happens when we have not used the transaction for several minutes...Looks like the transactions are moved away from the SAP buffer or something, in a very short time.
and yes, the ABAP WP's are running in Pool 2 (*BASE) and the the JAVA server, I have set up in another memory pool of 7 GB's.
I would say the performance of the JAVA part is much better than the ABAP part.
Should I just remove the ABAP part of the SOLMAN from memory pool 2 and assign the JAVA/ABAP a separate huge memory pool of say like 12-13 GB's.
Will that likely to improve my performance??
No, I have not deactivated RSDB_TDB in TCOLL from daily twice to weekly once on all systems on this box. It is running daily twice right now.
Should I change it to weekly once on all the systems on this box? How is that going to help me?? The only thinng I can think of is that it will save me some CPU utilization, as considerable CPU resources are needed for this program to run.
But my CPU utilization is anyway only like 30 % average. Its a i570 hardware and right now running 5 CPU's.
So you still think I should deactivate this job from daily twice to weekly once on all systems on this box??
Markus, Did you open up any messages with SAP on this issue.?
I remember working on the 3.2 version of soultion manager on change management and the response times very much better than this as compared to 4.0.
Let me know guys and once again..thanks a lot for your help and valuable input.

2013 Workflow Service - Enabled for Other Site Collections

I have setup the 2013 workflow service with our SharePoint environment. This works fine with the site collection originally used to register the workflow service.
The other site collections (in the same web application - we are using host named site collections) cannot see this, and SharePoint designer gives the error: "The option for the SharePoint 2013 Workflow platform is not available because the workflow
service is not configured on the server".
Now as the other site collections are in the same web application, the have the service connection to the "Workflow Service Application Proxy".
I have also seen posts about running a "Enable-SPFeature" command on the other site collections to enable WorkflowService or WorkflowServiceStore but this only returned an error (essentially) saying the futures were already enabled.
Where else can I look to try and diagnose what is wrong or what can I do to allow the other site collections to get access to the 2013 workflow service?
Thanks,
Richard

Hi,
According to your post, my understanding is that the SharePoint 2013 workflow platform not worked in other site collection.
Did you enable the workflow service application proxy? You can enable it as below, then check whether it works.
Whenever a new workflow service application proxy is created in SP2013, by default it will not be associated(service connection) with any web application.
You can go to Central admin site->Manage web applications page -> Select the web app which was registered earlier during configuration and check " workflow service application proxy" and click OK.
Did the workflow platform work in other web application?
If they all not work, I recommend you reconfigure the workflow manager, you can also check the steps with the following articles.

How to run "WCF Workflow Service Application" (C# project) using "WCF Test Client" in VS 2013 ?

I have created a WCF Workflow Service Application of C# project.
How to run the project using WCF Test Client directly from VS 2013 by doing F5 ?
Iam using VS 2013 (.NET 4.5.1). It throws an exception to compile c# expressions.
Can we set any settings in web.config file ?
Please provide the solution.

Bhanu Prakash T,
It surprises me that building a simple WCF Workflow Service Application project in VS 2013 is giving you this problem. That project template should result in a file with an extension of ".xamlx" being generated. With .Net 4.5 and C#, that XAMLX
file will contain CSharp* activities for the expressions that you specified in the workflow definition. By default, those expressions will be compiled when you use "F5" to execute the workflow.
Or are you self-hosting the WorkflowServiceHost and loading the XAMLX file yourself using ActivityXamlServices.Load and then creating and managing the WorkflowServiceHost object instance yourself? You must can do the compilation yourself by following these
examples -
https://connect.microsoft.com/VisualStudio/feedback/details/741537/cannot-self-host-a-workflow-service-using-c-expressions or http://wf.codeplex.com/discussions/444990.

Hi,
If you want to send an email when the status is changed please do the following custominzing:
T.Code SPPFCADM
Select appl. CRM_ORDER and Define Action Profile
Enter into action profile SMIN_STD and copy SMIN_ STD_MAIL to ZMIN_STD_MAIL (Include "Z" into the description to identify later)
Select Schedule Automatically and Partner Dependant (select Reporter, Support Team...based on you requirement)
Check in Processing Type that Method, Class and SmartForm is assigned.
Now you have define the action profile.
Come back to T.Code SPPFCADM
Select appl. CRM_ORDER and Condition configuration
Active Technical Names and go trough SMIN_ STD, you should create here the action profile defined in the previous step. In the right side go to button "create" and select the action profile ZMIN_STD_MAIL.
Into this new step go to Schedule Condition Tab where you should create a new definition, when you want that the action is execute (button Edit Condition) where you should create a condition like:
USER STATUS = E0001SMIN0001 (E0001 is the status and SMIN0001 the status profile assigned to the transaction type)
Now you have schedule your action profile
The last work is to configure the t.code SCOT. It should be done by your basis team.

What's the function of the null transactional manager server?

how to use the null transactional manager server?

If you need to call a service while in a transaction, but that service
does not use a resource manager (database), then it should be in a group
with the null TMS.
If it is a leaf service, you could call it with TPNOTRAN, but if it has
to call other services that are part of the transaction, then it too
must be part of the transaction.
The first service called by a client that initiated a transaction will
become the coordinator, so it needs to have a TMS even if it is not
using a database.

SP2013 Workflow Service Application is not showing up only WF Service App proxy but the WF is working...

I configured Sharepoint Workflow Manager 1.0 in Sharepoint 2013 App Server running under Windows 2012 R2. The Workflow manager is working properly - I tested using Sharepoint Designer and Sharepiont Workflow 2013 is listed. But under Service Applications,
only Workflow Service Application Proxy shows up NO Workflow Service Application.
I followed the troubleshooting steps on this - I have re-registered WF many times but still only proxy is coming up.
http://blogs.msdn.com/b/laleh/archive/2014/09/03/sharepoint-2013-workflow-troublehsooting.aspx
I also run IPConfig /FlushDNS, rebooted App and WFE servers.
Any reason why WF Service Application is not showing up? Any resolution to have WF Service App show up?

Hi John,
I recommend to click Configuration Wizards in the Quick Launch of Central Administration site and then click Launch the Farm Configuration Wizard.
And then make sure that the Workflow Service Application is selected and then click Next. (You can uncheck the other service applications if you do not need them)
After that, the Workflow Service Application will show up.
Best regards.

Workflow service configuration issue

I am having issues setting up workflow service in my SharePoint 2013 environment. My setup is single server farm.
I see the workflow service under the "Manage Service Applications" option in the central administration (as show below), but I do not see this service available under the service for the server under "Manage Services on Server".When
I open Designer and try to create workflow, I do not see the drop down for SharePoint 2013 workflow.
I am also attaching the IIS screenshot.
Register-SPWorkflowService
–SPSite http://sharepointsite –WorkflowHostUri
http://server:12291 –AllowOAuthHttp
Also, when I go to "http://localhost:12291/" it shows me message "
The website declined to show this webpage"

John,
I'd work thru this: https://msdn.microsoft.com/library/azure/jj193529%28v=azure.10%29.aspx
Did you configure the App Mgmt Service Proxy? I got bit by that one - link below.
And my apologies, it's been a while since I installed WFM, but I *think* you need the WF Client on your developer workstation, and on the server. And you'll want to use the Microsoft Platform Mgr to do the installs - be careful, there are different
versions for the WFM Clients. Ah, just checked my OneNote on setups, here are some links that may help:
For workflow mgr setup, follow this pretty much exactly:

Transaction Management with ATMI or SQL

If a system has only single database server, that is, no distribution or heterogeneity,
application servers can use ATMI or SQL manage transations. My question is: which
method is better? In that case, whether it is unnesseary to use the TM service
of Tuxedo? Any comment is welcome.

Brian:
If you use the database's begin, commit, and rollback you must have all the database
work related to that transaction performed in one Tuxedo service. If you use
XA connections to the database and use the tp/tx family of function calls you
can split a transaction across multiple servers/services and it will be tied together
by Tuxedo.
Sometimes this is nice. Let's say your business transaction comprises three distinct
database operations which must be included in the same transaction. If you put
these in different services you can get individual timings for each operation
simply by turning on txrpt.
hope this helps.

The partner transaction manager has disabled its support for remote/network transactions....When inserting during trigger in linked server

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
