By default, you can log on to the OceanBase Migration Service (OMS) console as the admin user. Letters in the username are not case-sensitive. OMS allows you to assign different roles to users. This topic describes how to manage users.

Background information

Notice:

You can perform the following operations only as the admin user.

The left-side navigation pane of the OMS console provides the following tabs: Overview, Data Migration, Data Synchronization, Data Source Management, O&M and Monitoring, and System Management. The supported roles are Admin and User. The following sections describe role privileges:

  • Admin

    OMS supports the admin account of the Admin role and non-admin accounts of the Admin role.

    • The admin account of the Admin role

      The admin account is created in OMS by default, and has the following privileges:

      • Creates users of the Admin role.

      • Accesses all tabs in the left-side navigation pane of the OMS console.

      • Edits users, changes the password of each user, views tasks, and performs O&M and monitoring operations.

      • Deletes all other users.

    • Non-admin accounts of the Admin role

      A non-admin account has the Admin role but its username is not admin. A non-admin account has the following features:

      • Has the privilege to edit the user information for the account.

      • Has the privilege to view the information of other users.

      • Has the privilege to create accounts of the User role, but not the Admin role.

      • Has no privilege to delete users.

  • User

    • Has the privilege to access the Overview, Data Migration, Data Synchronization, and Data Source Management pages.

    • Has the privilege to view the projects created by the logged-on user on the Data Migration and Data Synchronization pages.

    • Has the privilege to view the data sources added by the logged-on user on the Data Source Management page.

    • Has the privilege to create projects and New Data Sources.

Create a user

  1. Log on to the OMS console.

  2. In the left-side navigation pane, choose System Management > User Management.

  3. On the User Management page, click Create User in the upper-right corner.

  4. In the Create User panel, specify the following parameters.

    Parameter Description
