Create a deployment

Deployments let you create and organize Oracle Cloud Infrastructure GoldenGate resources, and enables the OCI GoldenGate deployment console, where you can add and manage data replication processes. You can create deployments for Oracle Database, Big Data, Db2 for z/OS, Microsoft SQL Server, MySQL, and PostgreSQL sources or targets.

Before you begin

Before you create a deployment, review the following requirements:

  • If you enable public deployment console access in Step 15, OCI GoldenGate creates a load balancer in your tenancy VCN on your behalf. To ensure successful creation of the deployment and load balancer, you must have the appropriate policies, quotas, and limits in place.
  • In Oracle Cloud Infrastructure Identity and Access Management (OCI IAM) enabled tenancies, Step 16 requires you to select the credential store you'll use to log in to the deployment console.
  • Depending on your source and target technology types, you may need more than one deployment. If you're not sure how many deployments you need for your solution, see Example topologies for details.

To create a deployment:

  1. In the Console navigation menu, click Oracle Database, and then select GoldenGate.
  2. On the Deployments page, click Create deployment.
  3. In the Create deployment panel, enter a name and optionally, a description.
  4. From the Compartment dropdown, select a compartment in which to create the deployment.
  5. For Choose a deployment type, select Data replication.
  6. From the Select a technology dropdown, select one of the following technology types:
    • Oracle Database
    • Big Data
    • MySQL
    • PostgreSQL
    • Microsoft SQL Server
    • IBM Db2 for z/OS

    See what's supported to learn which databases and technologies you can use as OCI GoldenGate sources and targets.

  7. For Version, the latest version is automatically selected. Click Change version to select a different version.

    Note:

    Learn more about versions.
  8. Select one of the following options:
    • Development or testing: Sets up a deployment with recommended defaults for a development or testing environment. The minimum number of OCPUs is 1.
    • Production: Sets up a deployment with recommended default of 4 OCPUs with auto-scaling enabled for a production environment. The minimum number of OCPUs needed is 3, with auto-scaling enabled.
  9. For Select OCPU enter the number or click Change shape to use the slider to choose the number of Oracle Compute units (OCPUs) to use.

    Note:

    One OCPU is equivalent to 16gb of memory. For more information, see OCPU management and billing.
  10. (Optional) Select Auto scaling.

    Note:

    Auto scaling enables OCI GoldenGate to scale up to three times the number of OCPUs you specify for OCPU Count, up to 24 OCPUs. For example, if you specify your OCPU Count as 2 and enable Auto Scaling, then your deployment can scale up to 6 OCPUs. If you specify your OCPU Count as 20 and enable Auto Scaling, OCI GoldenGate can only scale up to 24 OCPUs.
  11. From the Subnet in <Compartment> dropdown, select the subnet to which a private endpoint is created from the OCI GoldenGate service tenancy. This ensures that the deployment is always available over this subnet, as long as the policies for this subnet allow access.

    To select a subnet in a different compartment, click Change compartment.

    Note:

    You can only select a private subnet when creating or updating a deployment.
  12. Select a license type.
  13. For GoldenGate instance name, enter the name that the deployment will assign to the GoldenGate deployment instance upon creation.
  14. For Credential store, select one of the following:
    • OCI Identity and Access Management (OCI IAM), to enable users to log in to the the deployment console using their Oracle Cloud account (single sign on) in IAM (Identity and Access Management) enabled tenancies.

      Note:

      Once you select IAM, you won't be able to switch to GoldenGate when you edit the deployment settings at a later time.
      1. (Optional - applies only to Data Replication deployments) Select Customize group to role mappings to map user groups to specific GoldenGate roles. At minimum, you must assign the Security role group to a user group. Learn more about Oracle GoldenGate user roles and privileges.
    • GoldenGate, for GoldenGate to manage users.
      1. Enter the Administrator username
      2. Select a password secret in your compartment or click Change compartment to select one in a different compartment. You can also create a new password secret.

        To create a new password secret:

        1. Click Create password secret.
        2. In the Create secret panel, enter a name for the secret, and optionally, a description.
        3. Select a compartment from the Compartment dropdown in which to save your secret.
        4. Select a vault in the current compartment, or click Change compartment to select a vault in a different compartment.
        5. Select an Encryption key.

          Note:

          Only AES keys, Software protected keys, and HSM keys are supported. RSA and ECDSA keys are not supported for GoldenGate password secret keys.
        6. Enter a password 8 to 30 characters in length, containing at least 1 uppercase, 1 lowercase, 1 numeric and 1 special character. The special characters must not be '$', '^' or '?'.
        7. Confirm the password.
        8. Click Create.

      Note:

      You can manage GoldenGate users in the deployment console. Learn more.
  15. (Optional) Click Show advanced options for network options and to add tags.
    1. In the Network tab,
      1. Select Enable GoldenGate console public access to include a public endpoint in addition to a private endpoint, and allow public access to the deployment console for users. If selected, OCI GoldenGate creates a load balancer in your tenancy to create a public IP. Select a public subnet in the same VCN as this deployment in which to create the load balancer.

        Note:

        The load balancer is a resource that comes with an additional cost. You can manage this resource, but ensure that you don't delete the load balancer while your deployment is still in use. Learn more about load balancer pricing.

      2. Select Customize endpoint to provide a private fully qualified domain name (FQDN) prefix that you'll use to access the private service console URL. You can also optionally upload an SSL/TLS certificate (.pem) and its corresponding private key, however, password protected certificates are not supported.

        • It's your responsibility to ensure that the FQDN resolves to the deployment's private IP address in the subnet you previously selected.
        • If the deployment is public, it's your responsibility to ensure that the FQDN publicly resolves to the deployment's public IP address.

        The services uses its own certificate, if you don't provide one, and you may encounter security warning when launching the deployment console.

        Note:

        Your SSL certificate must meet the following requirements:
        • It's common name should match the deployment's FQDN. If it doesn't, you'll encounter warnings when you access the deployment console.
        • It must be signed using a strong hashing algorithm. arcfour, arcfour128, arcfour256, none algorithm types are not permitted.
        • It must not be expired.
        • It's maximum validity should not exceed 13 months.
        • It must not be a self-signed certificate.
        If you encounter "Invalid Private Key" errors, you can check the correctness of the key using the following OpenSSL commands. Run this command against the certificate:
        openssl x509 --noout --modulus --in <cert>.pem |openssl md5

        Then run this command on the private key:

        openssl rsa --noout --modulus --in <key>.pem |openssl md5

        The output of the two commands should return the same md5 value. If it doesn't, then the certificate and private key don't match.

    2. In the Maintenance tab:
      1. Select Customize maintenance window to define the start of the maintenance window to upgrade the deployment.
      2. (Optional) For Major release auto-upgrade period in days, enter the number of days, between 0 and 365.
      3. (Optional) For Bundle release auto-upgrade period in days, enter the number of days, between 0 and 180 days.
      4. (Optional) For Security patch auto-upgrade period in days, enter the number of days, between 0 and 14 days.
      5. Select Enable minor release auto-upgrade, and, optionally, enter the number of days.

      Note:

      Learn more about scheduling upgrades.
    3. In the Tags tab, add tags to help track the resources within your tenancy. Click + Additional tag to add more tags. Learn more about tagging.
  16. Click Create to create the deployment, or click Save as Stack to save this configuration to Resource Manager.

    If you select Save as stack, then the Save as stack panel opens, where you can optionally provide a name and description for the stack and select the compartment to save it in. Learn more about Resource Manager.

After the deployment is created and becomes Active, it starts automatically. You can then select Launch console in the deployment's Actions (three dots) menu on the Deployments page, or click Launch console on the deployment details page to access the OCI GoldenGate deployment console.

Ensure that you create and assign connections to use with your deployment.

Assign a connection to a deployment

Ensure that you have connections created for your source and target technologies.
To assign a connection to a deployment:
  1. On the deployment details page, under Resources, click Assigned connections.
  2. Click Assign connection.
  3. In the Assign connection dialog, select a connection from the dropdown. If you want to select a connection from a different compartment, click Change Compartment.
  4. Click Assign connection.
The selected connection appears in the Assigned connections list. You can also view and manage this relationship from the Connection details page under Assigned deployments.

When you assign a connection to a deployment, GoldenGate removes disallowed characters from the name you entered and trims it to 30 characters in length. The name must only contain alphanumeric characters, and follow the alias pattern: ^[a-zA-Z][a-zA-Z0-9_#$]*$. If a connection with the same alias is already assigned, a number is automatically added to the new alias name.

Access the deployment

After you create the Data replication deployment and assign connections, you can access the OCI GoldenGate deployment console from the deployment details page.

To access the OCI GoldenGate deployment:
  1. On the OCI GoldenGate Deployments page, select the Data replication deployment.
  2. On the deployment details page, click Launch console.
    Alternatively, you can copy the Console url and paste it into your browser.
  3. For an IAM-enabled deployment, you're prompted to give the application access to get_groups. Click Allow to continue.
  4. For a non-IAM enabled deployment, on the log in page, enter the Administrator username and Administrator password provided when you created the deployment.
You can now explore the deployment console or start adding Extracts, Replicats, and Paths to build your data replication solution.
