tAmazonAuroraClose – Docs for ESB 6.x

tAmazonAuroraClose

Closes an active connection to an Amazon Aurora database instance to release the
occupied resources.

tAmazonAuroraClose Standard properties

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

The Standard
tAmazonAuroraClose component belongs to the Cloud and the Databases families.

The component in this framework is generally available.

Basic settings

Component List

Select the tAmazonAuroraConnection component that opens the
connection you need to close from the list.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job 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.

Usage

Usage rule

This component is more commonly used with other Amazon Aurora
components, especially with the tAmazonAuroraConnection and tAmazonAuroraCommit components.

Dynamic settings

Click the [+] button to add a
row in the table and fill the Code field
with a context variable to choose your database connection dynamically from
multiple connections planned in your Job. This feature is useful when you
need to access database tables having the same data structure but in
different databases, especially when you are working in an environment where
you cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of
Talend Studio
.

Once a dynamic parameter is defined, the Component List box in the Basic
settings
view becomes unusable.

For examples on using dynamic parameters, see Scenario: Reading data from databases through context-based dynamic connections and Scenario: 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
.
