A Namespace is a logical group of resources that consists of datastores, networks (application network), and external storage (local and cloud storage) created by a Provider Administrator in VMware Data Services Manager. It is a logical grouping or subset of the resources in an environment that can be used for provisioning a database.
Namespaces View
As a Provider Administrator, you can see the following columns:
| Column Name | Description |
|---|---|
| Namespace Name | The name of the Namespace. |
| Environment | The environment with which the Namespace is associated. |
| Status | The status or current state of the Namespace. Status can be Init, Online, or Warning. |
| Associated Organizations | The number of organizations associated with the Namespace. |
| Number of Databases | The number of databases created by using the Namespace. |
| Last Modified | The time and date of last modification of the Namespace. |
If you click a Namespace in the Namespaces view, you can get more information about the Namespace through the following tabs:
- The Details tab, which provides information about the various resources of a Namespace and allows you to edit the resources.
- The Alerts tab, which provides information about the health of the Namespace and enables you to filter alerts on the basis of Datastore, Cloud Storage, and Local Storage. If any storage has reached 90% of it capacity or is not reachable by the Agent VM, the Namespace Health Status turns to Critical.
- The Database Metrics tab, which provides information about the top 10 databases that use the Namespace, in the order of CPU and memory consumption . You can also filter the metrics on the basis of a selected organization, database, or the customised range of time configured by you for the metrics.
- The Datastore Metrics tab, which provides information about the Datastore Usage By Database Instances and Datastore Free Space of the Namespace. You can also filter the metrics on the basis of a Datastore or the customised range of time configured by you for the metrics.
- The Organizations tab, which provides information about organizations and databases associated with the Namespace, and enables you to filter on the basis of organization name, status of the organization with respect to the Namespace, and number of databases associated with the Namespace. This tab also allows you to add or remove association of organizations to the Namespace and edit resources of the Namespace.
Databases and Namespace
Apart from provisioning Replica databases, all other database operations, such as backup, restore, recover, PITR, and so on, use the same Namespace as the database VM on which these operations are performed.
While creating Replica databases in an organization, you can select from the list of Namespaces associated with the organization and vCenter that have the Primary database node. Therefore, Replica databases and the Primary database of a database cluster can be associated with different Namespaces that are associated with different environments. Thus, you can create Zone Redundant Database High Availability Clusters.
If you navigate to Databases in the left navigation pane, you can see the Namespace associated with a particular database in the Namespace column of the Databases view.
If you navigate to Namespaces in the left navigation pane, you can see the number of databases created using a particular Namespace in the Number of Databases column of the Namespaces view.
Limitations of a Provider Admin on Database Operations
If the Namespace with which a database is created is not shared with the Provider organization, only the following operations can be performed on the database by the Provider Administrator:
