    Why are timeflow point parameter needed while provisioning? Is Snapshot not enough to give enough information? What is "firstChangePoint" and "latestChangePoint" in Snapshot object returned from API?


    #Virtualization

    Hello Anshul,
                        The database’s history is represented as a collection of snapshots and logs that create the Timeflow.

    You need time-flow point parameters, to provision VDB from any point in time between snapshots.

    From Oracle perspective, FirstChangePoint is a start of RMAN process, lastChangePoint is the last SCN of RMAN backup and Delphix need archive logs between to made backup consistent.

    Hope this explains.

    I want to provision a VDB. Provisioning API requires TimeFlowPointParameters in which I have to give location. To get location, I fetch the dSource List, from dSource List I fetch Snapshots. Now each snapshot in list has 2 timeflow point locations:   FirstChangePoint and lastChangePoint.
    Which one to use for provisioning?

    You can use either, it simply depends on when you want your data to be from.
