OceanBase Migration Service (OMS) Community Edition allows you to download the settings of migration objects in a data migration task and supports automatic configuration and verification of object settings based on imported CSV files. This allows you to promptly save task settings and configure multiple migration tasks at a time. This feature is suitable for renaming and setting hundreds of objects at a time.
Download object configuration
After you create a data migration task by specifying migration objects, you can download the settings of the objects.
Log in to the OMS Community Edition console.
In the left-side navigation pane, click Data Migration.
On the Data Migration page, click the name of the task whose object settings you want to download.
On the details page of the task, click the More icon in the upper-right corner, and then choose Download Task Configuration from the drop-down list.
Notice
If you set the migration object selection mode to Match Rules for a migration task, you cannot download the object settings of the task.
Import object settings
OMS Community Edition allows you to rename databases and tables and set row filter conditions by importing CSV files. You can download a template CSV file, modify it as needed, and then import it.
Notice
If you edit the object information in an Excel file, separate the columns with commas (,), save the file as a CSV file, and then import the CSV file.
The imported CSV file must contain the following columns: source database name, source table name, target database name, target table name, column mapping, and row filter condition.
Create a data migration task.
Log in to the OMS Community Edition console.
In the left-side navigation pane, click Data Migration.
On the Data Migration page, click New Task in the upper-right corner.
Create a migration task based on your business needs. On the Select Migration Objects page, select Specify Objects. In the right-side list of the Specify Migration Scope section, click Import Objects in the upper-right corner.
Notice
You can import objects only after you select the Specify Objects mode.
The specific procedure of creating a data migration task depends on the source and target nodes you select. For more information, see Create a data migration task.
In the dialog box that appears, click OK.
Click Import CSV File in the lower part of the Import Objects dialog box, and select a local CSV file to import it.
You can also click Download CSV Template in the lower part of the dialog box to download the template. Then, configure the settings in the template as needed and click Import CSV File to import the migration objects.
Edit the CSV file as needed.
Note
You can edit the CSV file manually or by using an SQL script. You can also click Download Task Configuration on the details page of the task to generate a CSV file.
You can enter names of databases or tables in the target database to establish a mapping between the source and target.
Click Validate to check whether the source objects exist and whether the row filter conditions are correct. If the verification succeeds, the number of verified tables and views is displayed.
Click OK to return to the Select Migration Objects step of the data migration task.
Complete subsequent task settings as prompted.
