tAccessCommit

Commits in one go a global transaction instead of doing that on every row or
every batch, and provides gain in performance, using a unique connection.

tAccessCommit validates the data processed through the Job into the
connected database.

tAccessCommit Standard properties

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

The Standard
tAccessCommit component belongs to the Databases family.

The component in this framework is generally available.

Basic settings

Component list	Select the tAccessConnection component in the list if more than one connection are planned for the current Job.
Close Connection	This check box is selected by default. It allows you to close the database connection once the commit is done. Clear this check box to continue to use the selected connection once the component has performed its task. Warning: If you want to use a Row > Main connection to link tAccessCommit to your Job, your data will be committed row by row. In this case, do not select the Close connection check box or your connection will be closed before the end of your first row commit.

Component list

Select the tAccessConnection
component in the list if more than one connection are planned for
the current Job.

Close Connection

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

Warning:

If you want to use a Row > Main connection to link tAccessCommit to your Job, your
data will be committed row by row. In this case, do not
select the Close connection
check box or your connection will be closed before the end
of your first row commit.

Advanced settings

tStat Catcher Statistics	Select this check box to collect log data at the component level.

Usage

Usage rule	This component is more commonly used with other tAccess* components, especially with the tAccessConnection and tAccessRollback 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.
Limitation	If you are using an ODBC driver, you need to work with Java 7, and make sure that your JVM and ODBC versions match up: both 64-bit or 32-bit.
