OceanBase Migration Service (OMS) Community Edition allows you to view and update the configurations of a specified Incr-Sync component. When you update the configurations, the current configurations of the Incr-Sync component are automatically displayed. You can view or modify the configurations of the Incr-Sync component.
Limitations
OMS Community Edition allows you to update the configurations of an Incr-Sync component in the Running, Stopped, or Exception state.
After you update the configurations of an Incr-Sync component, the system will restart the Incr-Sync component for the update to take effect. Proceed with caution.
When a data migration or synchronization task fails, check the configurations of the task first, such as the basic information and user privileges of the source and target databases.
