Using shared Data Sources with DB components in Jobs with tRouteInput
Last updated: 9/1/2025
This scenario describes the usage of Data Sources with DB components in Jobs
containing tRouteInput, which can be started only from a Route using the cTalendJob
component.
The following procedure shows how to use shared Data Sources with the tJDBC* components as
an example. The same rules are valid for all DB components that support Data Sources.
Procedure
Use the tPrejob to initialize the DB connection with
tJDBCConnection.
Configure the tJDBCConnection for the Data Source by specifying the
Data Source alias created on the Talend Runtime side.
Use the tPostjob to close the Data Source connection with
tJDBCClose.
This is not valid for Data Service operation Jobs that contain the tESBProvider*
or tRESTRequest component. In these kind of Jobs it’s not recommended to use the
close connection components like tJDBCClose, because closing Data Source connection
is implemented in the tESBProvider* or tRESTRequest component directly.
In the main part of the Job use commit or rollback components to
control the transaction to the connected DB.
Use the existing connection configuration for all DB components in
the Job.
