Hi All,

We have a problem with file output nodes.

We get a huge file through file input node. We do computing on that file and generate severaly small files. Now as these files have to be transferred to another FTP server.

Since the number of output files generally are too many and while in the process of transfer of these files if there is a network error, the tranfer of files stops, an exception in the broker is generated for the input file.

Now my problem is while reprocessing. Few number of files have already recahed the destination FTP server and has got processed. Is there any way we can ensure that all the outputs get generated locally and they get transferred and if there is any network error, I can reprocess them again.

How about splitting the operation into two flows.

The first reads the message and splits it up and puts them onto a queue

The (new) second one reads each message as a transaction in its own right and is coded to handle errors. Multiple instances would stop blocking in the event of one doing a retry.

Just an idea to start with.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

You could untick the remote transfer box so your flow creates all the files locally and doesn't automatically do the transfer. Then when the flow finishes successfully, ftp the files to their destinations.
