Set up a Connection
Prerequisites
The prerequisites to establish a connection:
Whitelisting Ports
Whitelist the inbound port to allow OvalEdge to connect to the Teradata Server database.
When a port is configured, specify the required port number during connection setup, whitelist the port, and establish proper communication between the system and the Teradata Server.
Service Account User Permissions
Use a dedicated service account to establish the connection to the data source, configured with the following minimum set of permissions.

Connection Configuration Steps
Users must have the Connector Creator role to configure a new connection.
Log in to OvalEdge, go to Administration > Connectors, click + (New Connector), search for Teradata, and complete the required parameters.
Connector Type
By default, "Teradata" is displayed as the selected connector type.
Credential Manager*
Select the desired credentials manager from the drop-down list. Relevant parameters will be displayed based on the selection.
Supported Credential Managers:
Database
HashiCorp
AWS Secrets Manager
Azure Key Vault
License Add-On
Auto Lineage
Supported
Data Quality
Not Supported
Data Access
Not Supported
Select the Auto Lineage Add-On checkbox to build data lineage automatically.
Connector Name*
Enter a unique name for the Teradata connection
(Example: "Teradata_Prod").
Connector Environment
Select the environment (Example: PROD, STG) configured for the connector.
Connector Description
Enter the description related to the connector.
Server*
Enter the IP address of the server where Teradata is hosted.
Port*
Enter the required Teradata port number.
Database*
The ‘Database’ field specifies the default schema to connect to within the Teradata server.
Example: If the target database is sales_db, enter sales_db to connect directly instead of the default schema.
Driver*
By default, Teradata uses ‘com.teradata.jdbc.TeraDriver.’ This field is not editable.
Username*
Enter the Username for the Teradata server.
Password*
Enter the Password associated with the Teradata Username.
Connection String
Configure the connection string for the Teradata server:
Automatic Mode: The system generates a connection string based on the provided credentials.
Manual Mode: Enter a valid connection string manually.
Replace placeholders with actual server details:
{server} refers to the Teradata host or IP address.
{sid} refers to the database name (schema).
Authentication Plugins: jdbc:teradata://{server}/DBS_PORT={port},database={sid}
This is the default authentication string used for connecting to the Teradata database.
Plugin Server
Enter the server name when running as a plugin server.
Plugin Port
Enter the port number on which the plugin is running.
Default Governance Roles
Default Governance Roles*
Select the appropriate users or teams for each governance role from the drop-down 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 & Governance Admin. All users configured in OvalEdge Security are available for selection.
No of Archive Objects
No Of Archive Objects*
This shows the number of recent metadata changes to a dataset at the source. By default, it is off. To enable it, toggle the Archive button and specify the number of objects to archive.
Example: Setting it to 4 retrieves the last four changes, displayed 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.
After entering all connection details, the following actions can be performed:
Click Validate to verify the connection.
Click Save to store the connection for future use.
Click Save & Configure to apply additional settings before saving.
The saved connection will appear on the Connectors home page.
Manage Connector Operations
Crawl/Profile
The Crawl/Profile button allows users to select one or more schemas for crawling and profiling.
Navigate to the Connectors page and click Crawl/Profile.
Select the schemas to crawl.
The Crawl option is selected by default. Click the Crawl & Profile radio button to enable both operations.
Click Run to collect metadata from the connected source and load it into the Data Catalog.
After a successful crawl, the information appears in the Data Catalog > Databases tab.
The Schedule checkbox allows automated crawling and profiling at defined intervals, from a minute to a year.
Click the Schedule checkbox to enable the Select Period drop-down.
Select a time period for the operation from the drop-down menu.
Click Schedule to initiate metadata collection from the connected source.
The system will automatically execute the selected operation (Crawl or Crawl & Profile) at the scheduled time.
Other Operations
The Connectors page in OvalEdge provides a centralized view of all configured connectors, including their health status.
Managing connectors includes:
Connectors Health: Displays the current status of each connector, with a green icon for active connections and a red icon for inactive connections, helping monitor connectivity to data sources.
Viewing: Click the Eye icon next to the connector name to view connector details, including Tables, Views, and Columns.
Nine Dots Menu Options:
To view, edit, validate, configure, build lineage, or delete connectors, click on the Nine Dots menu.
Edit Connector: Update and revalidate the data source.
Validate Connector: Check the integrity of the connection.
Settings: Modify connector settings.
Crawler: Configure data extraction.
Profiler: Customize data profiling rules and methods.
Query Policies: Define query execution rules based on roles.
Access Instructions: Add notes on how data can be accessed.
Business Glossary Settings: Manage term associations at the connector level.
Connection Pooling: Allows configuring parameters such as maximum pool size, idle time, and timeouts directly within the application.
Others: Configure notification recipients for metadata changes.
