Set up a Connection
Prerequisites
The following are the prerequisites to establish a connection:
Whitelisting Ports
Ensure the inbound port “9001” is whitelisted for OvalEdge to connect to the HSQLDB Server database.
The default port number for HSQLDB Server is 9001. If a different port is used, ensure that the updated port number is specified during connection setup, the port is whitelisted, and communication between the system and HSQLDB is properly established.
Service Account User Permissions
It is recommended to use a separate service account to establish the connection to the data source, configured with the following minimum set of permissions.
👨💻 Who can provide these permissions? These permissions are typically granted by the HSQLDB administrator, as users may not have the required access to assign them independently.

Port*
By default, the port number for the HSQLDB, "9001" is auto-populated. If required, the port number can be modified as per the custom port number that is configured for your HSQLDB.
Database*
Enter the database name to which the service account user has access within the HSQLDB.
Username*
Enter the service account username set up to access the HSQLDB database
(Example: "oesauser").
Password*

To perform crawl operations, users must be assigned the Integration Admin role.
The Crawl/Profile button allows users to select one or more schemas for crawling.
Navigate to the Connectors page and click Crawl/Profile.
Select the schemas to crawl.
The Crawl option is selected by default.
Click Run to collect metadata from the connected source and load it into the OvalEdge Data Catalog.
After a successful crawl, the information appears in the Data Catalog > Databases/Tables/Table Columns tab.
The Schedule checkbox allows automated crawling 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 crawl operation at the scheduled time.
Other Operations

Managing connectors includes:
Connectors Health: Displays the current status of each connector using a green icon for active connections and a red icon for inactive connections, helping to monitor the connectivity with data sources.
Viewing: Click the Eye icon next to the connector name to view connector details, including databases, tables, columns, and codes.
Nine Dots Menu Options:
To view, edit, validate, configure, or delete connectors, click on the Nine Dots menu.
Edit Connector: Update and revalidate the data source.
Validate Connector: Check the connection's integrity.
Settings: Modify connector settings.
Crawler: Configure data extraction.
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.
Delete Connector: Remove a connector with confirmation.
Connectivity Troubleshooting
If incorrect parameters are entered, error messages may appear. Ensure all inputs are accurate to resolve these issues. If issues persist, contact the assigned support team.
1
Connection failed: (message from driver/server)
Error Description:
The connection or validation query failed due to incorrect host, port, database, credentials, or network issues.
Resolution:
Verify network connectivity to the HSQLDB server, check host, port, and database name, validate username and password, review JDBC driver settings, and retry.
2
Failed to get fields: (message from driver/server)
Error Description:
The system failed to retrieve metadata such as tables, views, columns, and other database objects.
Resolution:
Ensure the service account has access to required database objects, verify permissions on schemas and system tables, and retry the crawl or refresh fields.
3
Invalid connection config.
Error Description:
The connection configuration is missing or incomplete.
Resolution:
Open the connector settings, fill in all mandatory fields, and validate the connection again.
