Component family

Databases/DB2

 

Basic settings

Component list

Select the tDB2Connection component in the list if more than one connection are planned for the current Job.

 

Close Connection

This check box is selected by default. It allows you to close the database connection once the commit is done. Clear this check box to continue to use the selected connection once the component has performed its task.

Warning

If you want to use a Row > Main connection to link tDB2Commit to your Job, your data will be committed row by row. In this case, do not select the Close connection check box or your connection will be closed before the end of your first row commit.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the component level.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio.

Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario 3: Reading data from MySQL databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.

Usage

This component is more commonly used with other tDB2* components, especially with the tDB2Connection and tDB2Rollback components.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.

Limitation

Note that the DB2 10.5 driver doesn't support JDK 8. To use this component with DB2 10.5, you need to install JDK 7 or an earlier version.
