9 Manual Scaling : 9.3 Manually Changing the Server Class

Use the Scale Machine Type dialog to copy the cluster into a larger server class.
When you use the Scale Machine Type dialog to move your cluster into a larger server class, you must provide a new name for the upgraded cluster. You can also use the dialog to specify that EDB Ark should re-assign the IP address of the cluster, so the upgrade will be transparent to connecting clients.
Use the pg_dump and pg_restore utilities to move the cluster into a larger server class.
To move to a larger server class, use the pg_dump utility to make a backup of the cluster. After backing up the cluster, create a new instance with the larger server class, and use pg_restore to restore the cluster on the new instance. For more information about using pg_dump and pg_restore, see Section 13.2 Moving an Existing Database into a New Cluster.
When you vertically scale your cluster with the Scale Machine 유형 dialog, EDB Ark will copy the existing cluster into a new cluster of a different server class, and optionally re-assign the IP address of the existing cluster to the new cluster.

Figure 9.5 - The Scale Machine Type dialog.
Use the fields on the Scale Machine 유형 dialog (shown in Figure 9.5) to specify details about the new cluster:
Check the box next to Perform OS and Software update to instruct EDB Ark to perform a yum update whenever the cluster is provisioned. Please note: this option is disabled if the database engine used to provision the cluster is statically provisioned.
Use the 서버 Class drop-down listbox to specify the size of the new cluster.
Please note that if you are a Template Only user, the types listed in the 서버 Class drop-down listbox will be limited to those types that are included in template definitions for the current tenant.
When you click the Scale button to start scaling the cluster, EDB Ark will confirm that the scaling is in progress.
Before creating the new cluster, EDB Ark will perform a backup of the original cluster. During the process, status indicators in the PENDING column of the Clusters tab will keep you informed as EDB Ark backs up the original cluster, and initializes the new cluster.
