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 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

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.
