tMDMConnection – Docs for ESB 5.x

Component family

Talend MDM

Function

tMDMConnection opens an MDM server connection
for convenient reuse in the current transaction.

Purpose

This component is used to open a connection to an MDM server that can then be
reused in the subsequent subjob or subjobs, to avoid having to specify the
connection details in each component.

Basic settings

URL

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, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.

Version (deprecated)

Type in the name of the Version of master data you want to connect to.

Leave this field empty if you want to display the default Version of master
data.

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.

Note that the auto commit function commits each SQL statement as a single transaction
immediately after the statement is executed while the commit component does not commit only
until all of the statements are executed. For this reason, if you need more room to manage
your transactions in a Job, it is recommended to use the commit component.

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.
