Impact on the system
This alert affects the real-time performance in incremental data migration and reverse data migration. If this alert is left unhandled for a long time, the migration task cannot be recovered.
Possible causes
The source or destination database is not properly configured.
Privileges are not properly assigned.
The network is disconnected.
Other special circumstances have occurred.
Solution
Go to the details page of the data migration project, and choose View Component Monitoring in the upper-right corner to view the timestamp information of the Store and JDBCWriter components.
If the Store component has a large delay, check its logs to check whether an error or exception has occurred.
If the timestamp information of the Store component is basically in real time but the JDBCWriter component has a large delay, check the logs of the JDBCWriter component to check whether an error or exception has occurred.
If no specific error message is found, feed back the phenomenon and component logs to technical support engineers of OMS.
