oms_migration_delay

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.
