tAmazonAuroraRollback – Docs for ESB 7.x

tAmazonAuroraRollback

Rolls back any changes made in the Amazon Aurora database to prevent partial
transaction commit if an error occurs.

tAmazonAuroraRollback Standard properties

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

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

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

Note: This component is a specific version of a dynamic database
connector. The properties related to database settings vary depending on your database
type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings

Database

Select a type of database from the list and click
Apply.

Component List

Select the tAmazonAuroraConnection component for which you want
the rollback action to be performed.

Close Connection

This check box is selected by default and it allows you to close
the database connection once the rollback is done. Clear this check
box to continue to use the selected connection after the component
has performed its task.

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 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.
