tAmazonMysqlConnection – Docs for ESB 7.x

tAmazonMysqlConnection

Opens a connection to the specified database that can then be reused in the
subsequent subjob or subjobs.

tAmazonMysqlConnection opens a
connection to the database for a current transaction.

tAmazonMysqlConnection Standard properties

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

The Standard
tAmazonMysqlConnection 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.

Property type

Either Built-in or
Repository.

 

Built-in: No property data stored
centrally.

 

Repository: Select the repository file in
which the properties are stored. The fields that follow are completed
automatically using the data retrieved.

DB Version

MySQL 5 is available.

Host

Database server IP address.

Port

Listening port number of DB server.

Database

Name of the database.

Additional JDBC parameters

Specify additional connection properties for the DB connection
you are creating.

Username and Password

DB user authentication data.

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.

Use or register a shared DB Connection

Select this check box to share your
database connection or fetch a database connection shared by a parent or child Job,
and in the Shared DB Connection Name field displayed, enter the
name for the shared database connection. This allows you to share one single database
connection (except the database schema setting) among several database connection
components from different Job levels that can be either parent or child.

This option is
incompatible with the Use dynamic job and Use an
independent process to run subjob
options of the
tRunJob component. Using a shared connection together with a
tRunJob component with either of these two options enabled
will cause your Job to fail.

Advanced settings

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.

tStatCatcher Statistics

Select this check box to collect log data at the 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 tAmazonMysql*
components, especially with the tAmazonMysqlCommit and tAmazonMysqlRollback components.
