Connecting to a DIS Data Source

Overview

ROMA Connect can use the DIS database as a data source for data integration tasks. Before using the DIS data source, you need to connect it to ROMA Connect.

Prerequisites

Each connected data source must belong to an integration application. Before connecting a data source, ensure that an integration application is available. Otherwise, create an integration application in advance.

Procedure

1. Log in to the ROMA Connect console. On the Instances page, click View Console next to a specific instance.
2. In the navigation pane on the left, choose Data Sources. In the upper right corner of the page, click Access Data Source.
3. On the Default tab page, select DIS and click Next.
4. Configure the data source connection information.
