These properties are used to configure tDB2Connection running in the Standard Job framework.

The Standard tDB2Connection component belongs to the Databases and the ELT families.

The component in this framework is available in all Talend products.

Note: This component is a specific version of a dynamic database connector. The properties related to database settings vary depending on your database type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings

Database

Select a type of database from the list and click Apply.

Property type

Either Built-in or Repository.

 

Built-in: No property data stored centrally.

 

Repository: Select the repository file in which the properties are stored. The fields that follow are completed automatically using the data retrieved.

Host name

Database server IP address.

Port

Listening port number of DB server.

Database

Name of the database.

Table Schema

Name of the schema.

Username and Password

DB user authentication data.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Encoding

Select the encoding from the list or select Custom and define it manually. This field is compulsory for DB data handling.

Use or register a shared DB Connection

Select this check box to share your database connection or fetch a database connection shared by a parent or child Job, and in the Shared DB Connection Name field displayed, enter the name for the shared database connection. This allows you to share one single database connection (except the database schema setting) among several database connection components from different Job levels that can be either parent or child.

This option is incompatible with the Use dynamic job and Use an independent process to run subjob options of the tRunJob component. Using a shared connection together with a tRunJob component with either of these two options enabled will cause your Job to fail.

This check box is not available when the Specify a data source alias check box is selected.

Specify a data source alias

Select this check box and specify the alias of a data source created on the Talend Runtime side to use the shared connection pool defined in the data source configuration. This option works only when you deploy and run your Job in Talend Runtime . For a related use case, see Deploying your Job on Talend Runtime to retrieve data from a MySQL database.

This check box is not visible when the Use or register a shared DB Connection check box is selected.

Data source alias

Enter the alias of the data source created on the Talend Runtime side.

This field is available only when the Specify a data source alias check box is selected.

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the DB connection you are creating.

Note:

You can set the encoding parameters through this field.

Auto Commit

Select this check box to commit any changes to the database automatically upon the transaction.

With this check box selected, you cannot use the corresponding commit component to commit changes to the database; likewise, when using the corresponding commit component, this check box has to be cleared. By default, the auto commit function is disabled and changes must be committed explicitly using the corresponding commit component.

Note that the auto commit function commits each SQL statement as a single transaction immediately after the statement is executed while the commit component does not commit only until all of the statements are executed. For this reason, if you need more room to manage your transactions in a Job, it is recommended to use the commit component.

tStatCatcher Statistics

Select this check box to gather the job processing metadata at a Job level as well as at each component level.

Usage

Usage rule

This component is more commonly used with other tDB2* components, especially with the tDB2Commit and tDB2Rollback components.
