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

The Standard tTeradataConnection 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

Database server IP address.

Database

Name of the database.

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.

Additional JDBC parameters

Specify additional connection properties in the existing DB connection, to allow specific character set support. E.G.: CHARSET=KANJISJIS_OS to get support of Japanese characters.

Note:

You can set the encoding parameters through this field.

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.

Advanced settings

Query band

Select this check box to use the Teradata Query Banding feature to add metadata to the query to be processed, such as the user running the query. This can help you, for example, identify the origin of this query.

Once selecting the check box, the Query Band parameters table is displayed, in which you need to enter the metadata information to be added. This information takes the form of key/value pairs, for example, DpID in the Key column and Finance in the Value column.

This check box actually generates the SET QUERY_BAND FOR SESSION statement with the key/value pairs declared in the Query Band parameters table. For further information about this statement, see https://docs.teradata.com/search/all?query=End+logging+syntax.

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 collect log data at the component level.

Usage

Usage rule

This component is more commonly used with other tTeradata* components, especially with the tTeradataCommit and tTeradataRollback components.

Limitation

Due to license incompatibility, one or more JARs required to use this component are not provided. You can install the missing JARs for this particular component by clicking the Install button on the Component tab view. You can also find out and add all missing JARs easily on the Modules tab in the Integration perspective of your studio. For details, see Installing external modules. .
