Ramasekhar,

Please find the answer in the article https://pdn.pega.com/about-pega-7-case-locking

Default locking stops two users working on the same case or two child cases of a Parent parallel by two users or  a Parent and child case by two users parallel at the same time.

Optimistic locking will allow two users to work on the same case or two child cases of a Parent parallel by two users in perform mode. But the recent updates commited to the case by the first user notifies the second user while he is submitting or commiting his changes to the case and ask him to refresh the case.

But in this two options we have the option to choose whether to lock the parent or not lock the parent while performing on the child case.

Default locking: When a case/work object opened by an operator, next operator want to open same, then the second operator has to wait untill first operator completes his work.

Opthmistic lock: When a case/work object opened by an operator, next operator want to open same, then the second operator no need to wait for first operator he can open the work object and work as well, when first operator completes his work on the work object then second operator will get a dialogue to refresh his work.

Hi Rama

Default Locking: Supports only one operator.

Optimistic Locking : Greater than one operator.

In default locking case when you run an activity on that particular workobject it fails even though the code is correct.

What about in the case of Optimistic Locking, where two users simultaneously submit on the same workobject/case - what will happen in that scenario?

Thanks.
