[resolved] Cannot execute multiple tRunJob at the same time

Anonymous — Fri, 02 May 2014 10:00:55 GMT

hi ,
I want to execute multiple jobs at the same time . Therefore i created a job with 3 tRunJob , i tried to check one process for each subjob , and without the option , but it doesn't work .
I don't know if the problem is in my jobs , because all of them use the tWaitForFile component, maybe it's the problem ,
please can you help ?
Thank you

Could you please share a screenshot of your job?
To run multiple things at the same time, you can either use the tParallelize or you can place three tRunJob components and configure your job to run multithread...

Here is my job :
- tParallelize don't exist natively in the palette
- I tried using multiple threads for each tRunJob , but it didn't work

largouwalid - Running as independent process simply spawns independent jvms for each subjob... But does not assure parallelism...

More info on the 2 options... http://www.talendforge.org/forum/viewtopic.php?pid=102860#p102860
tParallelize is an Enterprise version component, not the free Open Studio...
