Transaction in DFS doesn't work

rpdiaz

I have tried to implement a test transactional custom service (it creates 2 simple folders) but it doesn't work .

I attach the code (I think it is correct)

1) I invoke the DFS core services locally

2) I have configured the context to apply transactionallity

But the folders ALWAYS ARE CREATED!!! It does not do the rollback!!

anyone knows why it does not work??? Any idea would be appreciated.

Thank you!!

It seems your code is incomplete.

As far as I know, DFS does support transactional custom service. If the DFS version you used is 6.5 SP2 later, you can set the property IServiceContext.USER_TRANSACTION_HINT to IServiceContext.TRANSACTION_REQUIRED in the service context or operationOptions. Else you must set it in the service context.

The 2 folders should be added to the same DataPackage, then transaction will work. Any transaction on DFS side should happen in a single DFS service invocation. Such as creating 2 folders in a single service call. Transaction is actually implemented in DFC.

Hello all

thanks for your responses.

The fact is that we need to implement a service to do the following:

1) Create a folder with documents

2) Iniciate a workflow

if this is true (the transaction in DFS applies just to a service call) is not possible to implement transactions in a custom service which uses two different core Documentum services (object and bpm services in this case...???). There is no way to do that instead of using DFC???

Thanks

Raul,

It seems I am wrong. DFS can support different calls in a single transaction, but make sure using LOCAL service call.

Transactions in a custom service

DFS supports transactional service operations within the context of a single DFC instance. If your

custom services invokes other DFS services remotely, the remote services will execute in separate

DFC instances. If your custom service is transactional, these remote operations will not be included in

the transaction. However, if you invoke other DFS services locally, they will be executed within the

same DFC instance as your service, so they will be included in the transaction.

I call these services locally. The first operation that I do in my custom service is to set the context

(in the test the remoteMode flag is false):

privatetry{if(remoteMode){//objectService = serviceFactory.getRemoteService(IObjectService.class,serviceContext);objectService = serviceFactory.getRemoteService(IObjectService.class, serviceContext,"core","http://localhost:8888/services");workflowService = serviceFactory.getRemoteService(IWorkflowService.class, serviceContext, "bpm", "http://localhost:8888/services");}else{objectService = serviceFactory.getLocalService(IObjectService.class,serviceContext);workflowService = serviceFactory.getLocalService(IWorkflowService.class, serviceContext);}}catch (ServiceInvocationException e){e.printStackTrace();throw new RuntimeException(e);}}So this is why I do not understand the reason because this does not work...Thank you! void setService(){ServiceFactory serviceFactory = ServiceFactory.getInstance();

Raul,

May you send me your sample code to me? Let me have a try.

rpdiaz

Hello Jingzhi

I have attached the test code (you must set the repository, username and password as well as your own workflow name)...

When I force the error by an operation 1/0 the folder is always created and the transaction does not rollback.

Thank you for your help

Hi Raul,

Curious try throwing the ServiceExcpetion out instead of returning -1.

public int customService() throws ServiceException {

try {

.....

     } catch (ServiceException e) {
   // TODO Auto-generated catch block
        e.printStackTrace();

throw e;
// return -1;
}

Hi,

I have tried but it happens the same... any other ideas??

Thank you

Then it maybe a a bug or a feature request. I would suggest you open a Support case on this issue.

I have the same problem. Do you have any news?
