Terminating an Eon Mode database cluster
When you terminate an Eon Mode database's cluster, you free its resources. In a cloud environment, terminating the cluster deletes the instances that ran the database's nodes. In an on-premises database, terminating the cluster usually means repurposing physical hardware for other uses. See Stopping, starting, terminating, and reviving Eon Mode database clusters for more information.
Terminating an Eon Mode database's cluster does not affect the data it stores. The data remains stored in the communal storage location. As long as you do not delete the communal storage location, you can revive the database onto a new Eon Mode cluster. See Reviving an Eon Mode database clusterfor more information.
Important
Vertica persists catalog data in communal storage, updating it every few minutes. Nonetheless, before shutting down your database you should make sure your metadata is up to date on communal storage. To do so, see Synchronizing metadata.Terminating an Eon Mode cluster using Management Console
Management Console provides the easiest way to terminate an Eon Mode cluster. You must follow a two-step process: first stop the database, then terminate the cluster:
-
If you have not yet synchronized the database's catalog, follow the steps in Synchronizing metadata.
-
From the Management Console home page, click View Your Infrastructure.
-
In the row labeled Databases, click the database whose cluster you want to terminate.
-
In the popup, click Stop.
-
Click OK to confirm you want to stop the database.
-
After the database stops, in the row labeled Clusters, click the entry for the cluster you want to terminate.
-
In the popup, click Manage.
-
In the ribbon at the top of the cluster view, click Advanced and then select Terminate Cluster.
-
In the dialog box:
-
Check I understand that terminating a cluster will terminate all instances in the cluster
-
Click Terminate Cluster.
-
Manually terminating an Eon Mode cluster
To manually terminate your Eon Mode cluster:
-
If you have not yet synchronized the database's catalog, follow the steps in Synchronizing metadata.
-
Stop the database using one of the following methods:
-
Use the SHUTDOWN meta-function.
-
Terminate the database node instances. If you are in a cloud environment, see your cloud provider's documentation for instructions on terminating instances. For on-premises database clusters, you can repurpose the systems that were a part of the cluster.
