Re: Ending TCP/IP, FTP jobs in QSYSWRK

If you have your jobd logging level turned up to max, and this volume of
transactions,
you will get huge job logs that take a long time to complete.
You could do the OUTPUT idea in previous post
(and then deal with huge files, and a write a purge routine)
and reduce log level to minimum (if your ftp has been stable),
or cancel QTFTP jobs with option for minimal job log
example:ENDJOB JOB(123456/USER/XXX) OPTION(*IMMED) LOGLMT(1)
You could even write a clp to find all the qtftp jobs & do this.
I personally like the file output so it gets backed to tape, and is easy to
scan for problems.
