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
Access the details page of the migration task, click the More icon in the upper-right corner, and then choose View Component Monitoring to view the timestamp information about the store used for pulling logs and the JDBCWriter used for real-time synchronization.
If the store has a high latency, check for information about errors or exceptions in its logs.
If the timestamp information of the store is basically in real time but the JDBCWriter has a high latency, check the logs of the JDBCWriter for error or exception information.
If no specific error message is found, provide the symptoms and component logs to Technical Support of OMS Community Edition.
