tMDMRollback – Docs for ESB 7.x


Rolls back any changes made in the database rather than definitively committing
them, for example to prevent partial commits if an error occurs.

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

tMDMRollback Standard properties

These properties are used to configure tMDMRollback running in the Standard Job framework.

The Standard
tMDMRollback component belongs to the Talend MDM family.

The component in this framework is available in all Talend

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

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 +
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.
