OceanBase Migration Service (OMS) allows you to download the settings of migration objects in a data migration project and supports automatic configuration and verification of object settings based on imported CSV files. This allows you to save project settings and configure multiple migration projects at a time in a quick manner. This feature is suitable for renaming and setting hundreds of objects at a time.
Download object configuration
After you create a data migration project by specifying migration objects, you can download the settings of the objects.
Log on to the OMS console.
In the left-side navigation pane, click Data Migration.
On the Data Migration page, click the name of the project whose object settings you want to download.
On the details page of the project, click the More Actions icon in the upper-right corner, and then choose Download Project Configuration from the drop-down list.
Notice
If you set the migration object selection mode to Match Rules for a migration project, you cannot download the object settings of the project.
Import object settings
OMS 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, destination database name, destination table name, column mapping, and row filter condition.
Create a data migration project.
Log on to the OMS console.
In the left-side navigation pane, click Data Migration.
On the Data Migration page, click Create Migration Project in the upper-right corner.
Create a migration project based on your business needs. On the Select Objects page, select the Specify Objects mode. 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 if you select the Specify Objects mode.
The specific procedure of creating a data migration project depends on the source and destination nodes you select. For more information, see Create a data migration project.
In the dialog box that appears, click OK.
In the Import Objects dialog box, click Import CSV in the message and select a local CSV file to import it.
You can also click CSV Template in the message to download the template. Then, configure the settings in the template as needed and click Import CSV to import the migration objects.
Edit the CSV file as needed.
Description
You can edit the CSV file manually or by using an SQL script. You can also click Download Project Configuration on the details page of the project to generate a CSV file.
You can enter names of databases or tables in the destination database to establish a mapping between the source and destination.
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 project.
Complete subsequent project settings as prompted.
