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

The Standard tVerticaConnection component belongs to the Databases family.

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

Basic settings

Property type

Either Built-in or Repository.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

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.

DB Version

Select the version of Vertica you are using from the list.

Host

Database server IP address

Port

Listening port number of DB server.

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 JDBC parameters for the database connection being created.

Use or register a shared DB Connection

Select this check box to share your connection or fetch a connection shared by a parent or child Job. This allows you to share one single DB connection among several DB connection components from different Job levels that can be either parent or child.

Warning:

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.

Shared DB Connection Name: set or type in the shared connection name.

Advanced settings

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 tVertica* components, especially with the tVerticaCommit and tVerticaRollback components.

Used together, Talend Studio and the Vertica database create very fast and affordable data warehouse and data mart applications. For more information about how to configure Talend Studio to connect to Vertica, see Talend and HP Vertica Tips and Techniques.

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.
