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. |
Host |
Enter the location of the database server to be used. |
Port |

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. |
