Impact on the system

Solution

Impact on the system

This alert affects the real-time performance of data synchronization. If this alert is left unhandled for a long time, the migration project cannot be recovered.

Possible causes

  • The source and destination databases are 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 synchronization project, and click View Component Monitoring in the upper-right corner to view the timestamp information of the store and connector components.

  • 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 connector has a high latency, check the logs of the connector 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.
