Scale UP the shape of an existing DBCS System

In this use case, an existing OCI DBCS system deployed earlier is scaled up for its shape using Oracle DB Operator DBCS controller. Its a 2 Step operation.

In order to scale up an existing DBCS system, the steps will be:

  1. Bind the existing DBCS System to DBCS Controller.
  2. Apply the change to scale up its shape.

NOTE: We are assuming that before this step, you have followed the prerequisite steps to create the configmap and the secrets required during the deployment.

This example uses scale_up_dbcs_system_shape.yaml to scale up a Single Instance DBCS VMDB using Oracle DB Operator DBCS Controller with:

  • OCID of existing VMDB as ocid1.dbsystem.oc1.phx.anyhqljrabf7htyanr3lnp6wtu5ld7qwszohiteodvwahonr2yymrftarkqa
  • OCI Configmap as oci-cred
  • OCI Secret as oci-privatekey
  • Availability Domain for the DBCS VMDB as OLou:PHX-AD-1
  • Compartment OCID as ocid1.compartment.oc1..aaaaaaaa4hecw2shffuuc4fcatpin4x3rdkesmmf4he67osupo7g6f7i6eya
  • Database Admin Credential as admin-password
  • Database Hostname Prefix as host0130
  • Oracle VMDB Shape as VM.Standard2.2
  • SSH Public key for the DBCS system being deployed as oci-publickey
  • OCID of the Subnet as ocid1.subnet.oc1.phx.aaaaaaaauso243tymnzeh6zbz5vkejgyu4ugujul5okpa5xbaq3275izbc7a

NOTE: For the details of the parameters to be used in the .yaml file, please refer here.

Use the file: scale_up_dbcs_system_shape.yaml for this use case as below:

  1. Deploy the .yaml file:
[root@docker-test-server DBCS]# kubectl apply -f scale_up_dbcs_system_shape.yaml
dbcssystem.database.oracle.com/dbcssystem-existing configured
  1. Monitor the Oracle DB Operator Pod pod/oracle-database-operator-controller-manager-665874bd57-g2cgw for the progress of the DBCS VMDB Scale up.

NOTE: Check the DB Operator Pod name in your environment.

[root@docker-test-server DBCS]# kubectl logs -f pod/oracle-database-operator-controller-manager-665874bd57-g2cgw -n  oracle-database-operator-system

Sample Output

Here is the sample output for scaling up the shape of an existing DBCS System deployed in OCI using Oracle DB Operator DBCS Controller.
