    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.
