  • An existing source database.
  • An existing on-premises or Marketplace Oracle GoldenGate deployment

Task 1: Create OCI GoldenGate resources

  1. Create an OCI GoldenGate deployment.
  2. Create connections to your source and target databases.
  3. Assign connections to the deployment.

Task 2: Create a trusted connection between Oracle GoldenGate and OCI GoldenGate

Take care in distinguishing the Oracle GoldenGate Service Manager from the OCI GoldenGate deployment console while you complete this task.
  1. Download the root certificate for the OCI GoldenGate Deployment Console.

    Note:

    You can download the root certificate from any browser. The following steps describe how to download the root certificate from a Chrome browser.
    1. In your Chrome browser address bar, click the padlock icon, and then click Connection is secure.
    2. Click Certificate is valid. A Certificate window opens.

    6. Click Browse to save the file to your local drive.
    7. Click Next, and then click Finish.
  2. Upload the certificate to the on-premises or Marketplace Oracle GoldenGate Service Manager:
    1. Open the on-premises or Marketplace Oracle GoldenGate Service Manager in a browser window.
    2. In the navigation menu (hamburger icon), click Certificate Management.
    3. On the Certificate Management page, click Add CA Certificates (plus icon).
    4. In the Add CA Certificate dialog, enter a Unique Name.
    5. For Certificate PEM, copy and paste the contents of the certificate file you downloaded from Chrome, and then click Add.
  3. Add a user with which Oracle GoldenGate can use to connect to OCI GoldenGate.
    1. Launch the OCI GoldenGate deployment console from the deployment Details page.
    2. In the navigation menu, click User Administration.
    3. Click Add New User (plus icon), complete the fields as follows, and then click Submit:
      • For Authenticated By, select Password from the dropdown.
      • For Role, select Operator from the dropdown.
      • For Username, enter a name.
      • For Password, enter the password associated with this user. Verify the password.
    4. Open the on-premises or Marketplace Oracle GoldenGate Adminstration Service, and then navigate to the Path Connections page.
    5. Click Add Path Connection (plus icon), complete the fields as follows, and then click Submit:
      • Credential Alias: Enter an alias.
      • User ID: Enter the name of the user created in the previous step.
      • Password and Verify Password: Enter the password associated with this user.
    6. Click Submit.

Task 3: Send data from OCI GoldenGate to Oracle GoldenGate

This task instructs you on how to create and run a Target-initiated Path to pull Trail files from OCI GoldenGate to Oracle GoldenGate.
  1. In the OCI GoldenGate deployment console Oracle GoldenGate, add and run an Extract.
  2. On the on-premises or Marketplace Oracle GoldenGate, add a Target-initiated Path with the following values, and then click Create and Run:
    1. On the Source Options page:
      • For Source Host: Enter the OCI GoldenGate hostname in the following format, <domain>.deployment.goldengate.<region>.oci.oraclecloud.com:443.
      • For Trail Name: Enter a two-character name for the trail when it's received by OCI GoldenGate.
      • For Port Number: Enter the port number of the target deployment.
      • For Alias, enter the Credential Alias created in Task 2.
    2. On the Target Options page:
      • For Trail Name: Enter a two-character name for the trail when it's received by Oracle GoldenGate.
      • For Target Authentication Method (wss Target Protocol only):
        • If using GoldenGate credential store, then select UserID Alias.
        • If using IAM credential store, then use OAuth.
  3. On the on-premises or Marketplace Oracle GoldenGate, add a Replicat.
