Configure Oracle Exadata Database Service on Cloud@Customer with Exascale for Databases

Introduction

Exascale technology is now available with Oracle Exadata Database Service on Cloud@Customer. Users can configure Exascale storage on their new and existing Oracle Exadata Database Service on Cloud@Customer infrastructure and provision Exascale VM clusters using the configured Exascale storage.

Note: The following are the minimum requirements for configuring Exascale on Oracle Exadata Database Service on Cloud@Customer:

• Oracle Exadata X8M-2 System Model and later.
• Exadata Infrastructure System Software release 24.1.x and later.
• Oracle Grid Infrastructure 23ai and later.
• Oracle Database 23ai and later.

Objectives

• Configure Exascale storage on Oracle Exadata Database Service on Cloud@Customer infrastructure.

• Configure an Exascale storage vault.

• Create an Exascale VM cluster on Oracle Exadata Database Service on Cloud@Customer.

• Provision an Oracle Database 23ai container database.

• Scale an existing Exascale storage vault.

• Create Thin clone of a pluggable database.

Prerequisites

• Oracle Exadata Database Service on Cloud@Customer infrastructure available to host the VM cluster.

• A validated VM cluster network available for the VM cluster to use.

Task 1: Configure Exascale Storage on Oracle Exadata Database Service on Cloud@Customer Infrastructure

1. Log in to the OCI Console, navigate to Oracle Database and click Exadata Database Service on Cloud@Customer.

   

2. Select Region and Compartment where the Oracle Exadata infrastructure you want to edit is located and click Exadata Infrastructure.

   

3. Click the name of the Oracle Exadata infrastructure where you want to configure Exascale storage.

   

   In the Infrastructure Details page, click on the More Actions drop-down menu and select Configure Exascale storage.

   

4. Enter the Storage capacity for Exascale (TB) you want to allocate and click Submit.

   

   After the successful configuration of Exascale storage, the Exascale storage (TB) value is updated with the reserved storage capacity in the Exadata Infrastructure Details page.

   

Task 2: (Optional) Scale Up or Down the Exascale Storage Capacity

Note: If sufficient Exadata storage is unavailable to expand the Exascale storage, add additional storage servers using elastic storage expansion or reduce the storage allocated to existing VM clusters to make the desired Exadata storage capacity available for Exascale use.

To reduce the storage allocated to an existing VM cluster, follow the steps:

1. Navigate to the other VM cluster you want to reduce the storage allocated. In the VM Cluster Details page, click Scale VM Cluster.

   

2. In the Configure the Exadata storage section, specify the new value of the usable Exadata Storage in (TB) and click Save Changes.

   

   Users can scale up or scale down the allocated Exascale storage capacity. Users can expand the Exascale storage capacity up to the maximum Exadata storage available on the Exadata infrastructure, and reduce the capacity to 2 TB or total Exascale storage consumed by all Exascale storage vaults on the infrastructure, whichever is higher. Exascale storage can be scaled up or scaled down online at anytime.

3. In the Configure Exascale storage panel, the current capacity displays the currently allocated Exascale storage capacity. The minimum and maximum values display the minimum and maximum limits for the storage scale-up and down operations, respectively. Enter the value for the new allocated storage capacity for Exascale storage and click Submit.

   

Task 3: Configure an Exascale Storage Vault

An Exascale vault is a logical storage container that uses the physical resources provided by Exascale storage pools. Each vault is associated with at least one storage pool.

1. In the Exadata Infrastructure Details page, under Resources, click Exascale Storage Vaults.

   

2. Click Create Exascale storage vault.

   

3. In the Create Exascale storage vault page, enter the following information.

   • Compartment: Select a compartment where you want the Exascale storage vault to be created.

   • Storage capacity for the databases: Enter the storage capacity.

   Note: The minimum configurable or resizable size for an Exascale storage vault is 2 TB.

   

4. Click Create Exascale storage vault.

   

   While the creation process is running, the lifecycle state of the Exascale storage vault shows PROVISIONING.

   

   When the Exascale storage vault creation process completes, the state of the VM cluster changes to AVAILABLE.

   

   The Exascale Storage Vault details page displays information about the allocated storage and a list of VM clusters associated with the vault.

   

   Note: Alternatively, you can create a new vault on the fly using the Create new storage vault option while provisioning the Exascale VM cluster.

Task 4: Create an Exascale VM Cluster on Oracle Exadata Database Service on Cloud@Customer
