Connected synchronization is performed in a connected environment.
For replicas in a connected environment, there is a simple synchronization process. Here you connect to the replica geodatabases directly and choose the replica to synchronize. All the required message exchange to complete a synchronization is executed by the system. You never have to be concerned with message exchange or which replica is the sender or receiver.
Connected synchronization allows you to choose the direction in which the changes will be sent. For example, you can send changes from the parent replica to the child replica or from the child replica to the parent replica or in both directions. If you choose both directions, changes are first sent in one direction and then sent in the opposite direction, all in one operation. For checkout replicas, only the child replica to parent replica option is valid, while for one-way replicas, only the parent replica to child replica option is valid.
If an error occurs during synchronization, the operation is rolled back. Any changes that have been applied are removed and the system is put back as it was before the synchronization.
An exception to this rule can occur when you synchronize in both directions. Here, if an error occurs after the process of applying changes in one direction completes, these changes are committed. However, the system is still in a consistent state and further synchronizations are not affected.
