This component is closely related to tInformixCommit and tInformixConnection. They are generally used together to execute transactions.

Famille de composant

Databases/Informix

 

Function

tInformixRollback cancels transactions in connected databases.

Purpose

This component prevents involuntary transaction commits.

Basic settings

Component list

Select the tInformixConnection component from the list if you plan to add more than one connection to the Job.

 

Close Connection

Clear this check box if you want to continue to use the connection once the component has completed its task.

Advanced settings

tStatCatcher Statistics

Select this check box to collect the log data at a 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 must be used with other Informix components, particularly tInformixConnection and tInformixCommit.

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.
