DFS ObjectService.create(dataPackage, operationOptions)

Hello,

After adding multiple DataObjects to a DataPackage and invoking a create on the ObjectService, if atleast 1 of the objects failed ceration, then there is an exception, but the outcome is a creation of a partial set of DataObjects.

This behavior of ObjectService.create where it does not rollback the partial cerate is causing problems and forcing us to add additional code to catch the exception and spin through all the DataObjects to see which ones were created ... and so on.

Please let us know if there is an effective solution for this.

This is DFS 6.5 SP1

Thanks,

Ashwin

It seems that currently there is no better solution for this.

If the nubmer of the objects to create is not so big, creating the objects one by one can be considered.

Hi Ashwin,

You can use the java code to enable transaction when doing a number of object creation.

serviceContext.setRuntimeProperty(IServiceContext.USER_TRANSACTION_HINT, IServiceContext.TRANSACTION_REQUIRED);

Please don't set any of PAYLOAD_PROCESSING_POLICY in context property when use above setting.

Btw could you paste your code?

thanks

Hi Ashwin,

While creating objects using ObjsectService.create you can :-

1) FailOnException

2) ContinueOnException

If you want to FailOnException, then please add the following to the service context before service call

serviceContext.setRuntimeProperty(IServiceContext.PAYLOAD_PROCESSING_POLICY, "PAYLOAD_FAIL_ON_EXCEPTION");

Also if you don't set anything explicity, it should fail on exception.

Note that, FailOnException and ContinueOnException are for the unprocessed objects i.e., if there are 3 objects obj1, obj2, obj3 and obj2 creation fails and the payload processing policy is Fail On Exception , then obj3 will not be processed but obj1 will get created.But if policy is Continue On Exception then obj3 will get created (alongwith obj1) even if obj2 creation fails.

Thanks Abhijit.

But my requirement is that on a partial creation, the service should completely rollback. So, there are no confusions.

Thanks,

Ashwin,did you try my approach to enable transaction to address your problem?

Hi Ashwin,

I dont think it is possible to completely roll back. The already processed objects will get created eve if it is FailOnException.

Thanks
