catch runtime exceptions in Talend DI - tLogCatcher, tDie, "die on error"

Hello everyone,


I am seeking clarification on error handling in Talend DI (version 6.4).


If I use tLogCatcher to catch all exceptions in my Talend DI job then it appears that I must also use "On Error" flow to a tDie component (or to tWarn).

If this correct? If there a way to make it catch all errors without explicit tDie/tWarn on-error flows ?


I have tLogCatcher -> tFileOutput (or tLogCatcher ->tMap -> tFileOutput) to catch all errors.


This did not work until I explicitly added tDie to my sub-job "on Error" flow. Now it works.


If I check the "die on error" for a given component - is this same as flow to tDie on error i.e. will the error be caught by tLogCatcher  or do I still need explicit on-error tDie ?


Not all components have a "die on error".

Hi ,


I'm just using tLogCatcher --- tFileOutputDelimited to log my error and it's work fine.

Personnaly I use tDie or tWarning if i want to take care about special case.

But if you have something like : Job father calling Child Job , you have to put your tLogCatcher --- tFileOutputDelimited in two jobs otherwise, child job's error is not catched.
