tIngresCDC

Extracts source system data that has changed since the last extraction and
transports it to another/other system(s).

tIngresCDC addresses data extraction and transportation
needs, it only extracts the changes made to the source operational data and makes them
available to the target system(s) using database CDC views.

tIngresCDC Standard properties

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

The Standard
tIngresCDC component belongs to the Databases family.

The component in this framework is available in any
subscription-based Talend
solution.

Advanced settings

Encoding	Select an encoding type to be used from this list.
Keep data in CDC table	Select this check box to keep the changes made available to one or more target systems, even after they have been consulted.
Trim all the String/Char columns	Select this check box to remove leading and trailing whitespace from all the String/Char columns.
Trim column	Remove leading and trailing whitespace from defined columns. Note: Clear Trim all the String/Char columns to enable Trim columns in this field.
tStatCatcher Statistics	Select this check box to collect log data at a component level.
Enable parallel execution	Select this check box to perform high-speed data processing, by treating multiple data flows simultaneously. Note that this feature depends on the database or the application ability to handle multiple inserts in parallel as well as the number of CPU affected. In the Number of parallel executions field, either: Enter the number of parallel executions desired. Press Ctrl + Space and select the appropriate context variable from the list. For further information, see Talend Studio User Guide. Note that when parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subjob. The Action on table field is not available with the parallelization function. Therefore, you must use a tCreateTable component if you want to create a table. When parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subjob.

Global Variables

Global Variables	NB_LINE: the number of rows processed. This is an After variable and it returns an integer. 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.
