Set up a Connection

Prerequisites

The following are the prerequisites to establish a connection:

Whitelisting Ports

Ensure the inbound port “50005” is whitelisted for OvalEdge to connect to the DB2 database.

The default port number for DB2 is 50005. 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 DB2 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 DB2 administrator, as users may not have the required access to assign them independently.

Objects	System Tables	Access Permission
Schema	Syscat.Schemata	Select
Tables	Syscat.Tables	Select
Table Columns	Syscat.Columns	Select
Relationships	Syscat.Keycoluse, Syscat.References	Select
Views	Syscat.Views	Select
Procedures & Functions	Syscat.Routines	Select
Schema Users	Syscat.Schemata, Sysibmadm.Privileges	Select
Table Users	Syscat.Tabauth, Sysibmadm.Privileges	Select

Connection Configuration Steps

Users are required to have the Connector Creator role in order to configure a new connection.

1. Log into OvalEdge, go to Administration > Connectors, click + (New Connector), search for DB2, and complete the required parameters.

Fields marked with an asterisk (*) are mandatory for establishing a connection.

Field Name	Description
Connector Type	By default, "DB2" 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 your selection. Supported Credential Managers: OE Credential Manager AWS Secrets Manager HashiCorp Vault Azure Key Vault
License Add Ons	Auto Lineage Supported Data Quality Supported Data Access Not Supported 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.
Connector Name*	Enter a unique name for the DB2 connection (Example: "DB2_Prod").
Connector Environment	Select the environment (Example: PROD, STG) configured for the connector.
Connector description	Enter a brief description of the connector.
Server*	Enter the DB2 database server name or IP address (Example: xxxx-xxxx.xxxx4ijtzasl.xx-south-1.rds.amazonaws.com or 1xx.xxx.1.x0).
Port*	By default, the port number for the DB2, "50005" is auto-populated. If required, the port number can be modified as per custom port number that is configured for the DB2.
Database*	Enter the database name to which the service account user has access within the DB2.
Driver*	By default, the DB2 driver details are auto-populated.
Username*	Enter the service account username set up to access the DB2 database (Example: "oesauser").
Password*	Enter the password associated with the service account user.
Connection String	Configure the connection string for the DB2 database: 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 database details. {sid} refers to Database Name.
Plugin Server	Enter the server’s 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.

1. After entering all connection details, the following actions can be performed:

   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.

2. The saved connection will appear on the Connectors home page.

Manage Connector Operations

Crawl/Profile

To perform crawl and profile operations, users must be assigned the Integration Admin role.

The Crawl/Profile button allows users to select one or more schemas for crawling and profiling.

1. Navigate to the Connectors page and click Crawl/Profile.

2. Select the schemas you want to crawl.

3. The Crawl option is selected by default. Click the Crawl & Profile radio button to run both operations.

4. Click Run to collect metadata from the connected source and load it into the OvalEdge Data Catalog.

5. 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.

1. Click the Schedule checkbox to enable the Select Period drop-down.

2. Select a time period for the operation from the drop-down menu.

3. Click Schedule to initiate metadata collection from the connected source.

4. 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 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, build lineage, 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.

  • 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.

  • Anomaly Detection Settings: Configure anomaly detection preferences 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.

• Build Lineage: Automatically build data lineage using source code parsing.

• Delete Connector: Remove a connector with confirmation.
