Warning

Replace the <PLEASE_CHANGE> placeholder with appropriate values for your environment.

To configure the JDBC socket timeout, update the following property in Privacera Manager:

  1. SSH to the instance where Privacera Manager is installed.

  2. Run the following command to open the .yml file to be edited:

    If you have multiple connectors, then replace instance1 with the appropriate connector instance name.

    Bash
    1
    vi ~/privacera/privacera-manager/config/custom-vars/connectors/databricks-sql-analytics/instance1/vars.connector.databricks.sql.analytics.yml

  3. Set the following property to configure the JDBC socket timeout:

    YAML
    1
2
    # The maximum time to wait for data on a socket after connection establishment (default: 18000 seconds)
CONNECTOR_DATABRICKS_SQL_ANALYTICS_JDBC_SOCKET_TIMEOUT_IN_SECONDS: "<PLEASE_CHANGE>"

  4. Once the property is configured, run the following commands to update your Privacera Manager platform instance:

    Step 1 - Setup which generates the helm charts. This step usually takes few minutes.

    Bash
    1
2
    cd ~/privacera/privacera-manager
./privacera-manager.sh setup
    Step 2 - Apply the Privacera Manager helm charts.
    Bash
    1
2
    cd ~/privacera/privacera-manager
./pm_with_helm.sh upgrade
    Step 3 - Post-installation step which generates Plugin tar ball, updates Route 53 DNS and so on.

    Bash
    1
2
    cd ~/privacera/privacera-manager
./privacera-manager.sh post-install
