Component family

Talend MDM



tMDMRollback returns a database to its original state before a Job was run, instead of committing any changes.


This component is used as part of an overall MDM transaction to roll back any changes made in the database rather than definitively committing them, for example to prevent partial commits if an error occurs.

Basic settings

Component List

Select the tMDMConnection component for which you want the rollback action to be performed.


Close Connection

Select this check box to close the session for this connection to the MDM Server after rolling back the changes. Note that even if you do not select this check box, the connection can still not be used in a subsequent subjob unless the Autocommit mode has been enabled.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the processing metadata at the Job level as well as at each component level.

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.


This component is to be used along with the tMDMConnection, tMDMCommit, tMDMSP, tMDMViewSearch, tMDMInput, tMDMDelete, tMDMRouteRecord, tMDMOutput, and tMDMClose components.


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
