This topic describes the parameter template feature of OceanBase Migration Service (OMS) and user permissions of different roles on a parameter template.
Background
Components of a project in OMS are affected by factors such as hardware devices and the business of source and destination databases. You often need to adjust project parameters to meet business requirements. However, OMS supports parameter configuration only at the project level. If you need to create multiple projects to meet business requirements, you must repeatedly adjust parameters of those projects.
To simplify the parameter configuration, OMS provides the parameter template feature. This way, you can define parameter configuration requirements in a parameter template, and directly use the parameter template when you create a project. The feature allows you to quickly optimize parameters and ensures stable project operation.
Features
Project templates
On the Project Template tab, you can create, edit, copy, export, and delete a project template. For more information, see Create a project template.
After you define project parameters in a new project template, you can use the template when you create a data migration project.
Component templates
On the Component Template tab, you can create, edit, copy, export, and delete a component template. For more information, see Create a component template.
After you define component parameters in a new component template, you can use the template when you create a data migration project.
Permissions
Permissions on a parameter template depend on the creator rather than the last modifier of the template.
If your role is USER, you can view, manage, and use only templates created by you.
If your role is ADMIN of a department, you can view, manage, and use only templates created by users belonging to the department.
If your role is ADMIN-VIEWER of a department, you can view only the templates created by users belonging to the department.
If your role is ROOT, you can view, manage, and use templates created by all OMS users.
If your role is ROOT-VIEWER of a department, you can view only the templates created by all OMS users.
