Connecting to a MySQL Data Source

Overview

ROMA Connect can use the MySQL database as a data source for data integration tasks or data API creation. Before using the MySQL 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 first.

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 MySQL and click Next.
4. Configure the data source connection information.

   Table 1 Data source connection information

   Parameter	Description
   Name	Enter a data source name. It is recommended that you enter a name based on naming rules to facilitate search.
   Integration Application	Select the integration application to which the MySQL data source belongs.
   Description	Enter the descriptive information.
   Connection Mode	Select a database connection mode. Default: The system automatically concatenates data source connection character strings based on configured data. Professional: You need to specify the data source connection string manually. If the time zone of data written to a service is different from the default time zone of the MySQL database, you need to use the JDBC mode to connect to the database and specify the time zone in the JDBC connection string. For example, jdbc:mysql://10.10.10.1:3306/testfdi?serverTimezone=GMT%2B8. If the encoding character set of data written by a service is different from the default encoding character set in the MySQL database, you need to use the JDBC mode to connect to the database and specify the encoding character set in the JDBC connection string. For example, jdbc:mysql://10.10.10.1:3306/testfdi?characterEncoding=utf8.
   Connection Address	This parameter is mandatory only if Connection Mode is set to Default. Enter the IP address and port number for connecting the database.
   Database Name	This parameter is mandatory only if Connection Mode is set to Default. Enter the name of the database to be connected.
   Encoding Format	This parameter is mandatory only if Connection Mode is set to Default. Enter the encoding format used by the database.
   Timeout Interval	This parameter is mandatory only if Connection Mode is set to Default. Enter the timeout interval for connecting to the database, in seconds.
   Connection String	This parameter is mandatory only if Connection Mode is set to Professional. Enter the JDBC connection string of the MySQL database, for example, jdbc:mysql://{hostname}:{port}/{dbname}. {hostname} indicates the IP address for connecting to the database. {port} indicates the port of the database. {dbname} indicates the name of the database to be connected.
   Username	Enter the username used to connect to the database.
   Password	Enter the password used to connect to the database.

   • The following is an example of the database connection configuration in default mode:

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.
