If there is more than one connection in the Job, select tInformixConnection from the list.
This check box is selected by default. It means that the database conenction will be closed once the commit has been made. Clear the check box to continue using the connection once the component has completed its task.
If you are using a Row > Main type connection to link tInformixCommit to your Job, your data will be committed row by row. If this is the case, do not select this check bx otherwise the conenction will be closed before the commit of your first row is finalized.
Select this check box to collect the log data at a component level.
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.
This component is generally used along with Informix components, particularly tInformixConnection and tInformixRollback.
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.
