Getting Ready to Establish a Connection 

Prerequisites

The following are the prerequisites required for establishing a connection:  

Whitelisting Ports

Ensure the inbound port “5439” is whitelisted for OvalEdge to connect to the Redshift database.

Service Account User Permissions

Setup a Connection

1. Log into OvalEdge, go to Administration > Connectors, click + (New Connector), search for Redshift, and complete the specific parameters.
   Note: Fields marked with an asterisk (*) are mandatory for establishing a connection.
   

   Field Name	Description
   Connector Type	By default, "Redshift" is displayed as the selected connector type.
   Connector Settings
   Credential Manager*	Select the desired credentials manager from the dropdown list. Relevant parameters will be displayed based on your selection. Supported Credential Managers: OE Credential Manager AWS Secrets Manager HashiCorp Vault Azure Key Vault
   License Add Ons	OvalEdge connectors have a default license add-on for data crawling and profiling. Select the checkbox for Auto Lineage Add-On to build data lineage automatically. Select the checkbox for Data Quality Add-On to identify data quality issues using data quality rules and anomaly detection. Select the checkbox for Data Access Add-On, which will enforce connector access via OvalEdge with the Data Access Management (DAM) feature enabled.
   Connector Name*	Enter a unique name for the Redshift connection               (Example: "Redshift_Prod").
   Connector Environment	Select the environment (Example: PROD, STG) configured for the connector.
   Server*	Enter the Redshift database Server name or IP address (Example: https://abc1.cpgvvwcxxxes.us-xxxt-2.redshift.amazonaws.com/ or 192.168.1.10).
   Port*	By default, the port number for the Redshift database "5439" is auto-populated. If necessary, you can change this to a different port number.
   Database*	Enter the database name to which the service account user has access within the Redshift.
   Driver*	By default, the Redshift driver details (Example: com.amazon.redshift.jdbc.Driver) are auto-populated. OvalEdge artifacts include the required drivers for supported databases.
   Username*	Enter the service account username set up to access the Redshift database (Example: "oesauser").
   Password*	Enter the password associated with the service account user (Example: "password").
   Connection String	Configure the connection string for the Redshift database: Automatic Mode: The system generates a connection string based on the provided credentials. Example (Redshift):  jdbc:redshift://{server}:5439/{sid} Manual Mode: Manually enter a valid connection string. Example (Redshift): jdbc:redshift://{server}:{port}/{sid} Replace placeholders with actual database details. {sid} refers to Database Name

   
   

   Default Governance Roles
   Default Governance Roles*	Select the appropriate users or teams for each governance role from the dropdown list. All users and teams configured in OvalEdge Security are displayed for selection.
   Admin Roles
   Admin Roles*	Select one or more users from the dropdown list for Integration Admin and Security and Governance Admin. All users configured in OvalEdge Security are available for selection.
   No Of Archive Objects*	It indicates the number of recent metadata changes to a dataset at the source. By default, it is off. You can enable it by toggling the Archive button and specifying the number of objects to archive. Example: Setting it to 4 retrieves the last 4 changes, shown in the 'version' column of the 'Metadata Changes' module.
   Bridge
   Select Bridge*	If applicable, select the bridge from the drop-down list. The drop-down list displays all active bridges configured in OvalEdge. These bridges enable communication between data sources and OvalEdge without altering firewall rules.

2. After entering all connection details, you can perform the following actions:
   1. Click Validate to verify the connection.
   2. Click Save to store the connection for future use.
   3. Click Save & Configure to apply additional settings before saving.
3. The saved connection will appear on the Connectors home page.

Manage Connector Operations

Configure Settings for Connector Operations

The Redshift connector offers various settings to customize data crawling, profiling, and access. These include:

• Crawler: Configure data that needs to be extracted.
• Profiler: Customize data profiling rules and methods.
• Query Policies: Define rules for executing queries based on roles. 
• Access Instructions: Specify how data can be accessed as a note.
• Business Glossary Settings: Manage term associations at the connector level.
• Anomaly Detection Settings: Configure anomaly detection preferences at the connector level.
• Others: Configure notification recipients for metadata changes.

Crawl/Profile

Crawl and Profile operations enable you to select one or more schemas from a list of all available schemas within a specific database. This allows you to customize the crawling and profiling operations selection according to your requirements. Furthermore, it provides the option to schedule crawling and profiling and enable anomaly detection to identify any irregularities in the data objects.

Other Operations

The Connectors page in OvalEdge provides a centralized view of all configured connectors, including their health status. You can view, edit, validate, build lineage, and delete connector/Schema using the Nine Dots menu.

Managing connectors includes:

• Connectors Health: Displays performance with a green (active) or red (inactive) icon, helping monitor data flow and address issues early.
• Viewing: Shows connector details (e.g., Databases, Tables, Table Columns, and Codes) via the View icon.

Nine Dots Menu Options:

• Edit Connector: Update and revalidate the data source.
• Validate Connector: Check the connection's integrity.
• Settings: Modify connector settings.
• Build Lineage: Automatically build data lineage using SQL logs and source code parsing.
• Delete Connector: Remove connectors or schemas with confirmation.
