Rules and guidelines for running a
replication
task

Use the following guidelines when you run a
replication
task:
  • You cannot run multiple instances of a
    replication
    task simultaneously. If you run a
    replication
    task that is already running, the
    replication
    task fails with the following error:
    Data replication task failed to run. Another instance of task <Data Replication task name> is currently replicating the same objects.
    If you configured the
    replication
    task to run on a schedule, increase the time interval between the scheduled jobs to prevent multiple instances of the
    replication
    task from running simultaneously. If you run the
    replication
    task manually, wait for the currently running instance of the
    replication
    task to complete before starting it again.
  • If you run a
    replication
    task that excludes fields and that writes to a database target, the
    replication
    task drops any indexes defined on the excluded fields in the target table.
  • If you replicate timestamp data, the
    replication
    task truncates the millisecond portion of the timestamp data.
