Which tool is used during the Database Migration Option (DMO) procedure to monitor table splitting?

The Log viewer is the correct tool utilized during the Database Migration Option (DMO) procedure for monitoring table splitting. It provides essential information and insights into the migration process, including the status and progress of various operations, such as table splitting. This capability is crucial for administrators, as it allows them to keep track of how the migration procedure is unfolding and to identify any potential issues that may arise during the process.

Access to detailed logs helps ensure that the migration can be managed effectively, allowing for quick responses to any complications that might occur. The Log viewer specifically records and displays logs generated throughout the process, making it the most relevant tool for monitoring these operations during the DMO.

While tools like the Data Viewer, Query Monitor, and Observer Monitor serve valuable purposes in different contexts, they do not provide the targeted functionality required for monitoring table splitting within the DMO procedure. The Data Viewer focuses on validating data after migration, the Query Monitor tracks query performance, and the Observer Monitor is used primarily for overall system performance and health monitoring. None of these tools are specifically designed to handle the logging and monitoring of table splitting during database migration.
