Create ODB Network and ODB Subnets

This page describes how to create an ODB Network and ODB Subnets in Google Cloud.

An ODB Network provides connectivity between Oracle Database@Google Cloud resources in the Oracle Cloud Infrastructure (OCI) child site and your Google Cloud VPC network. The ODB Network maps OCI network resources, such as Virtual Cloud Networks (VCNs), and their related subnets back to Google Cloud.

When you create an ODB Network, Oracle Database@Google Cloud automatically provisions all of the underlying components that are required to establish this connectivity. This includes the VCN, subnets, DNS zones, and the other objects that maintain the private connection between Google Cloud and the OCI child site.

Oracle Database@Google Cloud also lets you create up to five ODB Subnets within an ODB Network for the ease of network management.

Before you begin

Create an ODB Network

An ODB Network must be created in the Google Cloud project that is associated to the billing account that you used for your marketplace order. In the case of a Shared VPC deployment, this project is also your host project and contains the Shared VPC network as well.

You must create the ODB Network in the same region and zone where you plan to create your Exadata Infrastructure, Exadata VM Cluster, or DB system. This ensures optimal performance and seamless communication.

To create an ODB Network, do the following:

Console

  1. Go to the ODB Network page.

    Go to ODB Network

  2. Click Create.

  3. From the Associated network list, select a VPC network which you want to associate with the ODB Network.

  4. Select a Region and a GCP Oracle zone.

    The region and zone choice is permanent and can't be changed later. If you aren't sure about which zone to select, you can select Any and Google Cloud automatically chooses a zone for you.

  5. Enter a name for the ODB network.

  6. Click Create.

gcloud

Use the gcloud oracle-database odb-networks create command to create an ODB Network.

gcloud oracle-database odb-networks create ODB_NETWORK_ID \
    --project=PROJECT_ID \
    --location=REGION \
    --network=projects/PROJECT_ID/global/networks/VPC_NETWORK

Replace the following:

  • ODB_NETWORK_ID: a unique identifier for your ODB Network.
  • PROJECT_ID: the ID of your Google Cloud project in which to create the ODB Network. If you're using a Shared VPC, then this is the ID of your host project.
  • REGION: the region in which to create the ODB Network.
  • VPC_NETWORK: the ID of the VPC network which you want to associate with the ODB Network.

API

To create an ODB Network, run the following curl command:

curl -X POST \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://oracledatabase.googleapis.com/v1/projects/PROJECT_ID/locations/REGION/odbNetworks/ODB_NETWORK_ID"
-d \
'{
  "network": "projects/PROJECT_ID/global/networks/VPC_NETWORK",
  "gcp_oracle_zone": "GCP_ORACLE_ZONE"
}'

Replace the following:

  • PROJECT_ID: the ID of your Google Cloud project in which to create the ODB Network. If you're using a Shared VPC, then this is the ID of your host project.
  • REGION: the region in which to create the ODB Network.
  • ODB_NETWORK_ID: a unique identifier for your ODB Network.
  • VPC_NETWORK: the ID of the VPC network which you want to associate with the ODB Network.
  • GCP_ORACLE_ZONE: the GCP Oracle zone in which to create the ODB Network.

After the ODB Network is created, you can create ODB Subnets.

Create an ODB Subnet

You can create two types of ODB Subnets:

  • Client ODB Subnets to connect to applications.
  • Backup ODB Subnets to back up database services.

For an ODB Network, you can create up to five ODB Subnets. A single Client ODB Subnet can be used by both Autonomous Databases and Exadata VM Clusters.

The number of ODB Subnets required depends on which service you want to use:

  • A Exadata VM Cluster requires one client subnet and one backup subnet.
  • An Autonomous Database requires one client subnet.

To create a subnet, do the following:

Console

  1. Go to the ODB Network page.

    Go to ODB Network

  2. Click the ODB Network for which you want to create the subnet.

  3. On the ODB Network details page, go to the Subnets section, and click Create.

  4. On Create ODB Subnet page, do the following:

    1. Enter a name for the subnet.

    2. Enter a range for the subnet in CIDR notation.

    3. Select the Subnet type.

    4. Click Create.

gcloud

Use the gcloud oracle-database odb-networks odb-subnets create command to create an ODB Subnet.

gcloud oracle-database odb-networks odb-subnets create ODB_SUBNET_ID \
    --project=PROJECT_ID \
    --location=REGION \
    --odb-network=ODB_NETWORK_ID \
    --cidr-range=CIDR_RANGE \
    --purpose=PURPOSE

Replace the following:

  • ODB_SUBNET_ID: a unique identifier for your ODB Subnet.
  • PROJECT_ID: the ID of your Google Cloud project in which to create the ODB Network. If you're using a Shared VPC, then this is the ID of your host project.
  • REGION: the region in which to create the ODB Subnet.
  • ODB_NETWORK_ID: the ID of your ODB Network for which you're creating the ODB Subnet.

  • CIDR_RANGE: To create a client subnet, provide the IPv4 address or address range that can access your cluster. If you're creating a backup subnet, then provide the IPv4 address or address range that serves as backup to access your cluster.

    Address ranges must use a valid CIDR notation (for example, 10.10.10.0/24).

  • PURPOSE: the type of the ODB Subnet that you want to create. The accepted values are client_subnet or backup_subnet.

API

To create an ODB Subnet, run the following curl command:

curl -X POST \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://oracledatabase.googleapis.com/v1/projects/PROJECT_ID/locations/REGION/odbNetworks/ODB_NETWORK_ID/odbSubnets/ODB_SUBNET_ID"
-d \
'{
  "cidr_range": "CIDR_RANGE",
  "purpose": "PURPOSE"
}'

Replace the following:

  • PROJECT_ID: the ID of your Google Cloud project that contains your ODB Network for which you want to create an ODB Subnet. If you're using a Shared VPC, then this is the ID of your host project.
  • REGION: the region of your ODB Network.
  • ODB_NETWORK_ID: the ID of your ODB Network for which you're creating the ODB Subnet.
  • ODB_SUBNET_ID: a unique identifier for your ODB Subnet.

  • CIDR_RANGE: To create a client subnet, provide the IPv4 address or address range that can access your cluster. If you're creating a backup subnet, then provide the IPv4 address or address range that serves as backup to access your cluster.

    Address ranges must use a valid CIDR notation (for example, 10.10.10.0/24).

  • PURPOSE: the type of the ODB Subnet that you want to create. The accepted values are client_subnet or backup_subnet.
