Exascale VM Cluster
To modify an existing Exascale VM Cluster, follow these steps.
Enable an Identity Connector on an Existing Exascale VM Cluster
-
From the Oracle AI Database@Google Cloud Console, expand the Exadata Database Service section, and then select Exascale Infrastructure.
-
Select the VM Clusters tab, and then select the Exascale VM Cluster that you are using.
-
On the Exascale VM Cluster details page, scroll down to the Identity Connector section.

-
Select Manage to access the Identity Connector management settings.
-
In the Manage Identity Connector page, configure the following setting:
-
Identity Connector enabled: Turn on the toggle to enable the Identity Connector, allowing the VM cluster to connect to Google Cloud services, such as Cloud KMS for Customer-Managed Encryption Keys (CMEK).
Note
Note:
-
The Identity Connector is required for Customer-Managed Encryption Keys (CMEK).
-
Automatic setup of Identity Connector may trigger alerts.
-
Identity Connector may be blocked if VPC-SC is enabled. To ensure OCI can access the Identity Connector, verify service account status and Cloud audit logs after setup. For more information, see Configure VPC Service Controls.

Select the Save button to apply the configuration changes.
Disable an Identity Connector on an Existing Exascale VM Cluster
-
From the Oracle AI Database@Google Cloud Console, expand the Exadata Database Service section, and then select Exascale Infrastructure.
-
Select the VM Clusters tab, and then select the Exascale VM Cluster that you are using.
-
On the Exascale VM Cluster details page, scroll down to the Identity Connector section.

-
Select Manage to access the Identity Connector management settings.
-
In the Manage Identity Connector page, configure the following setting:
-
Identity Connector enabled: Turn off the toggle to disable the Identity Connector.
Note
Note:
- The Identity Connector is required for Customer-Managed Encryption Keys (CMEK).
- You cannot disable the Identity Connector if your VM Cluster has a GCP Customer Managed Encryption Key enabled.

-
-
Select the Save button to apply the configuration changes.
Perform Management Operation
-
From the Oracle AI Database@Google Cloud Console, expand the Exadata Database Service section, and then select Exascale Infrastructure.
-
Select the VM Clusters tab, and then select the Exascale VM Cluster that you are using.
-
Select the Manage in OCI link.

-
Subsequent steps are performed through the OCI Console.
-
Modify Storage Vault
-
From the Oracle AI Database@Google Cloud dashboard, select Exadata Database Service > Exascale infrastructure from the left-menu.
-
Select the Storage Vault tab, and then select the Storage Vault you need to modify.
-
Select the Manage in OCI link.
-
This page allows you to Scale storage vault. For more information, see Manage Exascale Database Vaults on Exadata Database Service on Exascale Infrastructure.

-
You can select the Actions menu and Add Tags. For more information, see Overview of Tagging.

You can modify an Exascale VM Cluster in Google Cloud using OCI Terraform provider.
Prerequisites
-
Terraform or OpenTofu installed
-
HashiCorp OCI provider version >= 7.0
-
Exascale VM Cluster is created using Terraform
To modify an Exascale VM Cluster, perform the following steps:
-
Create a Modify configuration file and add the import block with the Exascale VM Cluster id. The id value can be found at the Create Exascale VM Cluster output block.
Sample Terraform Configuration using OCI Terraform Provider
# Set OCI Provider source and version terraform { required_providers { # OCI Provider oci = { source = "oracle/oci" version = "8.12.0" } } } # Configure the OCI Provider provider "oci" { tenancy_ocid = "ocid1.tenancy.oc1..aaaaaaaa2pg53mzroh6r2ub72r5mxxxxxxxxxxxxxpylciiqdihofe3dq" user_ocid = "ocid1.user.oc1..aaaaaaaaa6wyl3kzbgogsqpsixxxxxxxxxxxxxxxxuwzkemcrgue5q" private_key_path = "C:\OCI-Terraform\private-key.pem" # This example is for Windows OS fingerprint = "6c:c7:a7:60:f2:99:62:b9:8e:01:fc:e8:9b:eb:61:61" region = "us-desmoines-1" } # Import Exascale VM Cluster Configuration import { to = oci_database_exadb_vm_cluster.oci_exascale_vm_cluster id = "ocid1.exadbvmcluster.oc1.xxx.anuwcljtou6knayanpsxxxxxxxxxxxxxxxj74msrv4t53fkgrrspyxm3ona" # Replace the OCID value } -
Run the following commands in the Terminal window:
terraform initterraform validateterraform plan -generate-config-out="C:\GoogleCloud-Terraform\Working-Directory\generated_exascale_vm_cluster.tf" # An example on Windows OS -
Open the
generated_exascale_vm_cluster.tffile in a text editor and copy the content. -
Append the
generated_exascale_vm_cluster.tfcontent in the Modify configuration file. Remove the import block. -
Run the following command in the Terminal window:
terraform import oci_database_exadb_vm_cluster.oci_exascale_vm_cluster "ocid1.exadbvmcluster.oc1.xxx.anuwcljtou6knayanpsxxxxxxxxxxxxxxxj74msrv4t53fkgrrspyxm3ona" # Replace the OCID value -
Run the following command in the Terminal window to confirm the imported state file and the generated configuration file resources are in sync:
terraform plan -
Update the properties/values in the Modify configuration file as required.
Note
Note:
Modifying the configuration of Exascale VM Cluster using OCI Terraform provider will make the Create configuration file out of sync. To avoid out of sync Force replacement / Destroy issue, add the following lifecycle block in the Create configuration file.
lifecycle { ignore_changes = [ properties[0].enabled_ecpu_count_per_node, properties[0].additional_ecpu_count_per_node, properties[0].vm_file_system_storage[0].size_in_gbs_per_node ] }Sample Terraform Configuration using OCI Terraform Provider
