Connecting to a HANA Data Source

Overview

ROMA Connect can use the HANA data source for creating data integration tasks or data APIs. Before using the HANA data source, you need to connect it to ROMA Connect.

Prerequisites

Each connected data source must belong to an integration application. Ensure that an integration application is available before connecting a data source, or create one first.

Procedure

1. Log in to the ROMA Connect console. On the Instances page, click View Console of an 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 HANA and click Next.
4. Configure the data source connection information.

   Table 1 Data source connection information

   Parameter	Description
   Name	Enter a data source name. Using naming rules facilitates future search.
   Encoding Format	Default: utf-8
   Integration Application	Select the integration application to which the data source belongs.
   Description	Enter a brief description of the data source.
   Connection Mode	Select a connection mode for the database. Default Professional: JDBC is used for database connection.
   Connection Address	Mandatory only when Connection Mode is set to Default. Enter the IP address and port number for connecting the database.
   Database Name	Mandatory only when Connection Mode is set to Default. Enter the name of the database to be connected.
   Connection String	Mandatory only when Connection Mode is set to Professional. Enter the JDBC connection string of the HANA database, for example, jdbc:sap://{hostname}:{port}?databaseName={dbname}. {hostname} indicates the connection address of the database. {port} indicates the port number for connecting to the database. {dbname} indicates the name of the database to be connected.
   Username	Enter the username for connecting to the database.
   Password	Enter the password for connecting to the database.

   The connection configuration of the HANA data source is similar to that of the DB2 data source. For details, see Connecting to a DB2 Data Source.

5. Click Check Connectivity to check the connectivity between ROMA Connect and the data source.
   • If the test result is Data source connected successfully, go to the next step.
   • If the test result is Failed to connect to the data source, check the data source status and connection parameters, and click Recheck until the connection is successful.
6. Click Create.
