tMDMCommit properties

Component family

Talend MDM

 

Function

tMDMCommit explicitly commits all changes to the database made within the scope of a transaction in MDM.

Purpose

This component is used to control the point in an MDM Job at which any changes made to the database within the scope of an MDM transaction are committed, for example to prevent partial commits if an error occurs.

Note that if you need to commit each statement as an individual transaction, you have to use the Auto Commit function available in the connection component.

Basic settings

Component List

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

 

Close Connection

Select this check box to close the session for this connection to the MDM Server after committing 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.

Usage

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

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.
