tMemSQLConnection – Docs for ESB 6.x

tMemSQLConnection

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

tMemSQLConnection Standard properties

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

The Standard
tMemSQLConnection component belongs to the Big Data and the Databases families.

The component in this framework is available when you are using one of the Talend solutions with Big Data.

Basic settings

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.

Host

Enter the location of the database server to be used.

Port

Enter the listening port number of the database server to be
used.

Database

Enter the name of the database to be used.

Username and Password

DB user authentication data.

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

Additional JDBC parameters

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

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.
