After you start a data synchronization project, you can go to its details page to view its basic information, synchronization details, component monitoring, and synchronization objects.
Access the details page
Log on to the OceanBase Migration Service (OMS) Community Edition console.
In the left-side navigation pane, click Data Synchronization.
Click the name of the data synchronization project whose details you want to view to go to the details page.
On the details page, you can view the basic information, synchronization details, synchronization objects, and component monitoring of the project.
View basic information
The Basic Info section displays the basic information of the current data synchronization project.
Parameter |
Description |
|---|---|
| ID | The unique ID of the data synchronization project. |
| Project Type | The type of the data synchronization project. |
| Synchronization Type | The synchronization type of the data synchronization project. For example, Incremental Data Synchronization DML:UPDATE,DELETE,INSERT indicates incremental data synchronization in which the UPDATE, DELETE, and INSERT DML changes are to be synchronized. |
| Alert level | The alert level of the data synchronization project. OMS Community Edition supports the following alert levels: No Protection , High Protection , Medium Protection , and Low Protection . For more information, see Alert settings. |
| Created By | The user who created the data synchronization project. |
| Created At | The time when the data synchronization project was created. |
| Source and Destination | The source and destination databases of the data synchronization project. |
| Synchronization Start Timestamp | The synchronization start timestamp specified when the data synchronization project was created. |
View synchronization details
In the Synchronization Details section, you can view information about Schema Synchronization, Incremental Synchronization Log Pull, Full Synchronization, and Incremental Synchronization. Schema synchronization creates a topic. After the schema synchronization is completed, you can query the new topic.
The Incremental Synchronization section displays the latency and the current timestamp of the data synchronization project. Based on this information, you can learn the running status and performance of the data synchronization project.
The Incremental Synchronization Performance section displays the latency and traffic of incremental data synchronization in real time. You can view changes in synchronization performance by period or in real time.
Synchronization Latency displays the status and latency of the Store, Writer, and Connector components. Synchronization Traffic displays the TPS and IOPS of the JDBCWriter component. In the upper-right corner of the Incremental Synchronization Performance section, you can filter synchronized incremental data by Last 1 Hour, Last 24 Hours, Last 7 Days, or a custom period of time.
View and modify synchronization objects
On the details page of the data synchronization project, click View Synchronization Objects in the upper-right corner to view synchronization objects of the project.
When you synchronize data from OceanBase Database to a RocketMQ or Kafka instance, you can modify the synchronization objects of a paused data synchronization project.
Pause the data synchronization project.
If the project has been paused, skip this step.
On the details page of the project whose objects you want to modify, click Pause in the upper-right corner.
In the dialog box that appears, click OK.
On the details page of the project, click View Synchronization Objects in the upper-right corner.
In the View Synchronization Objects dialog box, click Modify Synchronization Objects in the lower-right corner.
In the Modify Synchronization Objects dialog box, add or remove the objects as needed.
You can also move the pointer over the object that you want to modify in the Destination Objects list, and change the topic or set ETL options.
Click OK.
View the component monitoring metrics
On the details page of the data synchronization project, click View Component Monitoring in the upper-right corner. You can view the information about the Store and Connector components.
You can view the ID, Earliest Timestamp, Current Timestamp, and Status of the Store component. You can perform the following operations:
Start the component: Click Start in the Actions column of the component that you want to start. In the dialog box that appears, click OK.
Pause the component: Click Pause in the Actions column of the component that you want to pause. In the dialog box that appears, click OK.
Update the component: click Update next to the component you want to update. On the Update Configuration page, modify the configurations and click Update.
Notice
The system restarts after you update the component. Proceed with caution.
View logs: Click the More icon for the component and choose View Logs from the drop-down list. The View Logs page displays the latest logs. Archived logs will not be displayed. You can search for, download, and copy the logs.
Destroy the component: If the component is in the Error or Stopped state, click the More icon for the component and choose Destroy from the drop-down list. In the dialog box that appears, enter delete to confirm the operation and click Delete .
You can view the ID, Current Checkpoint, Latency, and Status of the Connector component. You can perform the following operations:
Start the component: Click Start for the component. In the dialog box that appears, specify Whether to Replay Data and click Start .
Pause the component: Click Pause in the Actions column of the component that you want to pause. In the dialog box that appears, click OK.
Update the component: click Update next to the component you want to update. On the Update Configuration page, modify the configurations and click Update.
Notice
The system restarts after you update the component. Proceed with caution.
View logs: Click the More icon for the component and choose View Logs from the drop-down list. The View Logs page displays the latest logs. Archived logs will not be displayed. You can search for, download, and copy the logs.
Delete the component: Click the More icon for the component and choose Delete from the drop-down list. In the dialog box that appears, enter delete to confirm the operation and click Delete.
View parameters
On the details page of the data synchronization project, click the More icon in the upper-right corner and choose View Parameter Configurations from the drop-down list. On the page that appears, you can view the configuration parameters specified when the data synchronization project was created.
