IBM DB2 ZOS

This article outlines the integration with the IBM DB2 ZOS connector, enabling streamlined metadata management through features such as crawling, profiling, querying, data preview, and lineage building (both automatic and manual). The connector discovers schemas, tables, views, columns, relationships, indexes, functions, and stored procedures, and imports the collected metadata into OvalEdge.

The connector uses a JDBC Driver to establish connectivity with IBM DB2 ZOS. It authenticates using a dedicated IBM DB2 ZOS service account with the required permissions to access metadata and perform the configured connector operations.

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 IBM DB2 ZOS.

External Supporting Files

The required external JAR files are included as part of the OvalEdge installation artifacts. For driver installation and configuration details, refer to the Connector Drivers Setup Guide. Please contact the OvalEdge Team for assistance related to the driver files and configuration setup.

Service Account User Permissions

👨‍💻 Who can provide these permissions? These permissions are typically granted by the IBM DB2 ZOS administrator, as users may not have the required access to assign them independently.

  • Schema discovery combines metadata from SYSIBM.SYSTABLES, SYSIBM.SYSDATATYPES, SYSIBM.SYSROUTINES, and SYSIBM.SYSTRIGGERS.

  • Trigger metadata is used only for schema discovery. Trigger definitions are not crawled as separate metadata objects or included in lineage generation.

  • Row count profiling uses the catalog cardinality (CARDF) from SYSIBM.SYSTABLES instead of executing live COUNT(*) queries.

  • Index metadata is retrieved only when index crawling is enabled. This option may not be available in the connector configuration for IBM DB2 ZOS.

Connection Configuration Steps

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

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

Field Name
Description

Connector Type

By default, "IBM DB2 ZOS" 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:

  • OE Credential Manager

  • AWS Secrets Manager

  • HashiCorp Vault

  • Azure Key Vault

For more details, click here.

License Add Ons

Select the checkbox for Auto Lineage Add-On to build data lineage automatically.

For more details, click here.

Connector Name*

Enter a unique name for the IBM DB2 ZOS connection

(Example: "IBM DB2 ZOS_Prod").

Connector Environment

Select the environment (Example: PROD, STG) configured for the connector.

For more details, click here.

Connector description

Enter a brief description of the connector.

Server*

Enter the fully qualified host name or IP address of the IBM DB2 ZOS server that hosts the Distributed Data Facility (DDF) listener (Example: xxxx-sqlserver.xxxx4ijtzasl.xx-south-1.rds.amazonaws.com or 1xx.xxx.1.x0).

Port*

Enter the port number configured for the IBM DB2 ZOS DDF listener. The default value is 50005. Update this value if your environment uses a different DDF port

Database*

Enter the IBM DB2 ZOS Location Name configured for the target database. The value is case-sensitive and must be specified in uppercase as required by the IBM Db2 JDBC Type 4 driver.

Driver*

Displays the JDBC driver class used to establish the connection. The default value is com.ibm.db2.jcc.DB2Driver and cannot be modified. Ensure that the required db2jcc4.jar driver is available in the configured JDBC driver location before validating the connection.

Username*

Enter the username of the IBM DB2 ZOS service account used by the connector. Ensure that the account has the required permissions to access metadata and perform the configured connector operations.

Password*

Enter the password associated with the specified IBM DB2 ZOS service account. This password is used to authenticate the connection to the database.

Connection String

Configure the connection string for the IBM DB2 ZOS:

  • 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*

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*

Select one or more users from the drop-down list for Integration Admin and Security & Governance Admin. All users configured in OvalEdge Security are available for selection.

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.

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.
