File Interface Question

[Robert Milfajt]

We have an inbound fileset/ftp interface which files are received via FTP, and processed through to the appropriate destination.  Every so often Cloverleaf wants to read the file, while it is being FTP’d in and a file busy error causes the interface to drop into an error status.  Is there anyway to ignore the file busy and let Cloverleaf ignore the file on this iteration and pick it up the next time it scans the directory?

Thanks,

Bob

There are many ways of handling the problem. My suggestion is to write a Directory Parse proc that checks the file modification time of the file and makes sure that it hasn’t been modified for a few minutes before passing the filename back so that it gets picked up by Cloverleaf.  

Ideally, the sender of the file should FTP the file in with an alternate name and send a rename command after the upload is complete.  Then you don’t have to worry about the file being incomplete.

The second idea is excellent.  Now I am off to do battle with the vendor.  Wish me luck!   😈

We write our file procs to leave files alone that are not at least x minutes old. The interface keeps checking  for files every so often.

Hi,

Sorry to ressurect an old thread, but I was wondering if there is a simple way of achiving the reverse of this situation using Cloverleaf. We are interfacing with an external system where they have requested that we rename files upon successful population, or move them to the desired location after transfer to avoid any problems with incomplete files etc, but I cant see a way of achieving this without going outside of using the inbuilt Fileset-FTP protocol.

We have to turn these messages around really fast, so time based processing, or static filesize checks or whatever arent really an option.

If anyone has any ideas it would be much appreciated.

Mark,

In the FTP-fileset protocol, there is the ‘Temporary File’ field in the protocol configuration that is used for this purpose; i.e. write the data to a temp file and rename upon completion.  You may want to test it out using this option.  I’m not sure what CL version your on, but this option exists in 5.6.

Hope this helps.

Thanks Jim,

unfortunately it looks like a new feature inbetween 5.3 (our live version) and 5.6, which possibly answers if there is an easy way to achive this with Cloverleaf with keep software up to date!
