    • Establish a zero copy connection to an external Oracle database in Workflow Data Fabric Hub.

    Before you begin

    You can optimize queries to Oracle by enabling table statistics. Consult your data source admin to confirm whether table statistics are enabled in Oracle before enabling this option in Workflow Data Fabric Hub.

    Role required: df_connection_admin

    About this task

    Work with your data source admin to create a connection to Oracle. For additional information about connecting to Oracle, refer to the Oracle documentation.

    Procedure

    1. Navigate to the available primary connectors in Workflow Data Fabric Hub in one of the following ways:
      • Navigate to All > Workflow Data Fabric Hub > Available connectors > Primary connectors.
      • Navigate to Admin > Workflow Data Fabric Hub > Available connectors > Primary connectors.
    2. Find the Oracle connector and select Connect.
    3. On the form, fill in the fields.
      Table 1. New Oracle Connection form
      Field Description
      Name and description
      Connection label Unique name for this connection. This helps in identifying the connection within your system.
      Connection name System-generated name based on the Connection label. This field cannot be modified once the connection is established.
      Short description Description of the connection explaining what it is about.
      Connection attributes
      Connection URL JDBC URL from the tnsnames.ora file in the wallet to establish the connection. For example:

      jdbc:oracle:thin:@(description=(address=(protocol=tcps)(port=<port>)(host=<host>))(connect_data=(service_name=<service-name>)))
      Enable table statistics Option to enable table statistics.

      Optimize SQL queries using table statistics by selecting this option. Enabling table statistics allows the system to use estimates of stored data such as row count, distinct values, and data size for enhanced query processing.

      Note:
      You must ensure that gathering table statistics is enabled in the data source before selecting this option.
    4. Configure the authentication method that you want to use with Oracle.
      OptionDescription
      KeyStore - PEM (secure)
      1. Attach the wallet PEM file from the wallet folder using one of the following options:
        • Upload the wallet PEM file by selecting Attach PEM file and selecting the file.
        • Copy and paste the contents of the PEM file, ensuring the content contains one private key beginning with: 
          -----BEGIN ENCRYPTED PRIVATE KEY-----
          and ending with: 
          -----END ENCRYPTED PRIVATE KEY-----
          and two certificates, each beginning with: 
          -----BEGIN CERTIFICATE-----
          and ending with: 
          -----END CERTIFICATE-----
      2. Enter the database username associated with the source.
      3. Enter the database password associated with the username.
      4. Enter the PEM file password associated with the wallet.
      KeyStore - JKS (secure)
      1. Attach the Base64-encoded truststore.crt file from the wallet folder using one of the following options:
        • Upload the truststore file by selecting Attach TrustStore file and selecting the file.
        • Copy and paste the contents of the truststore file, ensuring the content begins with: 
          -----BEGIN CERTIFICATE-----
          and ends with: 
          -----END CERTIFICATE-----
      2. Attach the Base64-encoded keystore.crt file from the wallet folder using one of the following options:
        • Upload the keystore file by selecting Attach KeyStore file and selecting the file.
        • Copy and paste the contents of the keystore file.
      3. Enter the database username associated with the source.
      4. Enter the database password associated with the username.
      5. Enter the truststore password associated with the wallet.
      6. Enter the keystore password associated with the wallet.
      Username / Password
      1. Enter the database username associated with the source.
      2. Enter the database password associated with the username.
    5. Select Connect.

    Result

    A test connection is made to the external data source, verifying that the connection details are correct and the data source is accessible.

    What to do next

    If the connection succeeds, configure data steward access on the Access Control tab. See Manage access to an established connection using roles.

    If the connection fails, verify the connection details with your data source administrator and try again.
