My OnComponentError would never be fired?

[Anonymous]

Please see the design above:
I want to unzip all .gz files into a "temp" folder. In case if it fails when unzipping one .gz file, I want the filename and error message printed out.

But I also don't want the job to fail when that happens -- so I have "Die on Error" unchecked in tFileUnarchive step.

I used a fake .gz file (I renamed a regular text file as .gz file) with several real .gz files for testing.
I don't get the error message at all. I did have something show up in the print out area, but not from my code:



Is it because I unchecked "Die on Error" so the OnComponentError would never be fired?
Does anyone have a good idea to catch the filename and error message when there is a problem unzipping the file, but still let the job continue?

Thanks!

Hi,

as a variant which is definitely working - put Unzip and error logic into SubJob (tRunJob)

Uncheck DieOnChildError, but in the child job use Die On Error for component

another variant, use tSystem and If triggers:

Thank you so much for your quick response!

But I have problem understanding what you wrote, especially when I'm looking at your design screenshot --
could you please help create a more understandable job if you have time?

BTW, if I want to use tSystem to unzip a group of .gz files, what should the command be?

Thanks!

Hi,

I've provided 2 variants:

• using tRunJob - where all similar to your current design, you just need to relocate 2 components into subjob
• using tSystem, tSystem could run any command or program installed on machine

as an example - http://kb.winzip.com/kb/entry/124/ or https://stackoverflow.com/questions/41902600/how-would-i-extract-a-gz-file-from-cmd-using-only-comma... 

if the execution was successful, error code will be 0, if any error - not 0, and variables will display to you what happens

cheers,

I hope I understand you now.

I created a stand alone job ("unzip_file")  with tFileList --Iterate--> tFileUnarchive --OnComponentError -> tJava (Print out error message) . I checked " Die on Error" within tFileUnarchive.

In my original job, I replaced above subjob with a tRunJob component and it calls job "unzip file".
Leave "Die on child error" unchecked.

I launched the job -- this time, I saw my error message print out my code. BUT, there is one problem: the child job didn't unzip ALL of the files. I believe when it encountered the bad file, it failed and it stopped unzipping the rest of the files.

Please let me know if I did it correctly. Thank you!

you need to run subjob for each file (filename as parameter from parent)

Thanks! It's working now.
