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

The Standard tNamedPipeClose component belongs to the File family.

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

Basic settings

Pipe

Select an existing named-pipe from the list to close.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a 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.

Usage

Usage rule

This component is usually used to close a named-pipe at the end of a Job.

Dynamic settings

Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your pipe connection dynamically from multiple connections planned in your Job.

When a dynamic parameter is defined, the Pipe box in the Basic settings view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.

You can install the missing JARs for this particular component by clicking the Install button on the Component tab view. You can also find out and add all missing JARs easily on the Modules tab in the Integration perspective of your studio. For details, see Installing external modules.
