Data Replication monitors replication tasks that are running to prevent simultaneous execution of conflicting replication tasks for a particular configuration. Data Replication stores information about active replication tasks in the
DataReplication_installation
/lockDB.db3 SQLite database.
To help you prevent conflicts, the Data Replication Console provides the following restrictions:
You cannot start a replication task in the Data Replication Console or from the command line if it conflicts with one or more other active tasks that use the same configuration.
You cannot start a schedule if any running task that uses the same configuration conflicts with the scheduled tasks.
The following table describes, for each type of active replication task that uses a configuration, the types of simultaneous tasks that are conflicting and that are not conflicting:
