Trying to build retry logic for FTP Upload..

[Anonymous]

Hi,
I'm trying to build a job(let) that performs an FTPPut of a designated file to a server with retry logic added.
The joblet needs to be able to re-try the connection/upload a set number of time before giving up and failing.
I'm using TIS 4.1.2(r53616).
What we have tried so far is to use a tLoop to iterate and tRunJob that does the FTP. When we 'simulate' a failed connection (using wrong password) the FTP fails with an exception, however the tRunJob does not trigger the 'error' link..
Any advice on this?

Hi
The expression of If2(error link) is as follow.

((Integer)globalMap.get("tRunJob_1_CHILD_RETURN_CODE"))==1

Regards,
Pedro

I made the change and get the following result..

The job does not loop..

Can you change your IFs to onSubjobOK and onSubjobError?

[Anonymous]

Change the ifs to OnSubJobOK and OnSubJobError, allows the loop to iterates and clams it a success but the FTP fails.
