View the details of a data synchronization task

Go to the details page

1. Log on to the OceanBase console .

2. In the navigation pane on the left, click Data Transmission Service > Data Synchronization.

3. Click the name of the data synchronization task to open the details page and view the Basic Information and Synchronization Details.

   

   On the Data Synchronization page, you can search for data synchronization tasks by tag, status, type, and keyword. The task statuses include the following:

   • Not Configured: The task is not configured. In the Actions column, click Configure.

   • Upgrading/Downgrading: The instance type of the task is being upgraded or downgraded.

     If the current instance type cannot meet your needs, you can upgrade it. For more information, see Data Transmission Service specifications.

   • Not Started: The task has not started. In the Actions column, click Start.

   • Running: The task is running. You can view its progress and perform other operations in the Actions column.

   • Modifying: The synchronization objects of the task are being modified.

   • Merging: The modifications to the synchronization objects are being merged into the task.

   • Paused: The task has been manually paused. In the Actions column, click Resume to continue the synchronization.

   • Failed: The task has failed. The step at which the task failed is displayed next to the status. You can click the task name to view the error details on the details page.

   • Completed: The task has been successfully executed. Data Transmission Service has synchronized the specified data to the destination database based on the configured synchronous mode.

   • Ending: The task is being stopped. You cannot perform any operations on the task during this process.

   • Ended: The task has been stopped.

   You can modify the name of a task that is in the Not Started, Running, Paused, or Failed status. For more information, see Modify the name of a data synchronization task.

View basic information

The Basic Information section displays basic information about the data synchronization task.

You can perform the following operations:

• View and modify synchronization objects

  In the upper-right corner of the page, click View Objects to view the list of synchronization objects for the task. You can also modify the synchronization objects while the task is running. For more information, see View and modify synchronization objects and their filter conditions.

• View parameter settings

  In the upper-right corner of the page, click ... > View Parameter Settings to view the parameters that were configured when the task was created.

• View or modify parameter settings

  You can view the parameter settings of a task that is in the Upgrading/Downgrading, Running, Modifying, Merging, Completed, Ending, or Ended status. You can modify the parameter settings of a task that is in the Not Started, Paused, or Failed status. For more information, see View and modify synchronization parameter settings.

  The specific parameters that you can modify depend on the task type and its current stage.

• Download object configuration information

  In the upper-right corner of the page, click ... > Download Object Configuration to download the configuration information for the current task. The information is downloaded in a format that can be used for batch import. For more information, see Download and import synchronization object configurations.

View synchronization details

In the Synchronization Details area, you can view details for Structure Synchronization, Full Synchronization, and Incremental Synchronization. Structure synchronization is the process of creating a Topic. After the structure synchronization is complete, you can query the newly created Topic.

The Incremental Synchronization area displays information about the task, such as its status, latency, and current offset time. You can use this information to monitor task performance.

When you create a data synchronization task, you can enable monitoring and alerting to stay informed of the task status. For more information, see Set alerts. If monitoring and alerting is not enabled, the status of the incremental synchronization step switches from Running to Monitoring when the incremental synchronization latency is 10 minutes or less. If monitoring and alerting is enabled:

• If the incremental synchronization latency of the task is greater than the configured alert time, the incremental synchronization step remains in the Running status, and the system does not trigger an alert.

• If the incremental synchronization latency of the task is less than or equal to the configured alert time, the status of the incremental synchronization step switches from Running to Monitoring. After the status switches to Monitoring, it does not switch back to Running, even if the latency later exceeds the configured alert time.

The Incremental Synchronization Performance area displays real-time information about incremental synchronization. In the upper-right corner of the Incremental Synchronization Monitoring area, you can filter incremental synchronization data by Last 1 Hour, Last 24 Hours, Last 7 Days, or a custom time range. This lets you view real-time and segmented changes in replication performance.
