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

The Standard tMDMConnection component belongs to the Talend MDM family.

The component in this framework is available in all Talend products.

Basic settings

MDM version

By default, Server 6.0 is selected.

Although it is recommended to migrate existing Jobs for this new version, the Server 5.6 option is available to ease the process of the migration of your Jobs so as to keep them working without modification with a 6.0 server. To do so, an option on the server must be enabled to accept and translate requests from such Jobs.


Type in the URL required to access the MDM server.

Username and Password

Type in the user authentication data for the MDM server.

To enter the password, click the [...] button next to the password field, enter the password in double quotes in the pop-up dialog box, and click OK to save the settings.

Auto Commit

Select this check box to commit any changes to the database automatically upon the transaction.

With this check box selected, you cannot use the corresponding commit component to commit changes to the database; likewise, when using the corresponding commit component, this check box has to be cleared. By default, the auto commit function is disabled and changes must be committed explicitly using the corresponding commit component.

In the MDM context,

  • with this check box cleared, queries sent to the Talend MDM Server will be committed and the trigger, if any, will be executed only if the transaction is successfully committed.
  • with this check box selected, queries sent to the Talend MDM Server will be committed once they are successfully executed, and the trigger, if any, will be executed. For this reason, if you need more precision in managing your transactions in a Job, it is recommended to use the tMDMCommit component.
Warning: The trigger event will not occur if the Talend MDM Server goes down when the transaction is committed.

You can consult the mdm.log file to verify the execution results of the trigger. For more information, see Testing Triggers in the Studio of the Talend Studio User Guide.

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 + Space to access the variable list and choose the variable to use from it.

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