Managing a Tag

Scenarios

Tag Management Service (TMS) enables you to use tags on the management console to manage resources. TMS works with other cloud services to manage tags. TMS manages tags globally, and other cloud services manage their own tags.

• You are advised to configure predefined tags on the TMS console.
• A tag consists of a key and value. You can add only one value for each key.
• Each DB instance can have up to 10 tags.
• You can add tags when creating an evaluation project or a migration project, or add tags after the project is created.

Adding a Tag

1. Log in to the UGO console.
2. In the navigation pane on the left, choose Schema Migration > DB Evaluation or Schema Migration > Object Migration.
3. Click the project name.
4. On the Tags page, click Add Tag. In the displayed dialog box, enter a tag key and value, and click Add.
5. After all tags are added, click OK in the lower part of the dialog box. You can view and manage your tags of the current page.
