# tAssertCatcher Standard properties These properties are used to configure tAssertCatcher running in the Standard Job framework. The Standard tAssertCatcher component belongs to the Logs & Errors family. The component in this framework is available in all Talend products. ## Basic settings | Schema and Edit
schema | A schema is a row description, it defines the fields to be
processed and passed on to the next component. In this particular
case, the schema is read-only, as this component gathers standard
log information including: | | --- | --- | | | Moment: Processing time and
date. | | | Pid: Process ID. | | | Project: Project which the job
belongs to. | | | Job: Job name. | | | Language: Language used by the
Job (Java) | | | Origin: Status evaluation origin.
The origin may be different tAssert
components. | | | Status: Evaluation fetched
from tAssert. They may
be

- Ok: if the assertive statement
of tAssert is evaluated as true at
runtime.

- Failed: if the assertive
statement of tAssert is evaluated
as false or an execution error occurs at runtime. The tested Job's
result does not match the expectation or an execution error occured
at runtime. | | | Substatus: Detailed explanation
for failed execution. The explanation can be:

- Test logically failed: the
investigated Job does not produce the expected result.

- Execution error: an execution
error occurred at runtime. | | | Description: Descriptive message
typed in Basic settings of
tAssert (when Catch tAssert is selected) and/or the
message of the exception captured (when Catch
Java Exception is selected). | | | Exception: The Exception object
thrown by the Job, namely the original exception.

Available when Get original
exception is selected. | | Catch Java Exception | This check box allows to capture Java exception errors and show
the message in the Description
column (Get original exception not
selected) or in the Exception
column (Get original exception
selected) column, once checked. | | Get original exception | This check box allows to show the original exception object in the
Exception column, once
checked.

Available when Catch Java
Exception is selected. | | Catch tAssert | This check box allows to capture the evaluations of tAssert. | ## 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 the start component of a secondary Job which
fetches the execution status information from several sources. It
generates a data flow to transfer the information to the component
which proceeds. | | --- | --- | | Limitation | This component must be used with tAssert together. |
