Continue job execution after a connection fail

Anonymous — Sat, 16 Nov 2024 07:41:19 GMT

Hi all,
I have to build a job with the following scenario:
Connect in 15 different MYSQL databases, with different IP's, after connect on each one, it will retrive some informations from MySQL and store in a table inside an oracle database. The problem is sometimes the origin (mysql database) can be offline and if this situation happens I need that the kob continues the execution with te other databases but I don't know how to do that. If the connection is successfull retrieve data from mysql and store in oracle table but if the connection failled, go to the next myql database and continue the job. And i have to add this exception for every mysql connection attempt. How can I do that? Using a run if? But I don't know how to implement that in the job. A picture of the job is attached.

Ps: Im using talend open studio (free version).

please, can someone help me with this? Thanks in advance.

first of all take a closer look on the documentation and :
1 - OnComponentError and Ok

2 - OnSubJobError and Ok

Next use tMySQL<input> right mouse: based on 1 or 2 (mentioned above) you could start a different branch in your current job flow. look at the pictures.
And finally what @fdenis suggest also use a tlogCatcher (only need it once), this one you use to process and check wether you need re-run your job.
