The task of getting files (especially large data) from Linux to MVS is very important to me. FTP, seemed like it would be a obvious option. YMMV but for me it's too unreliable! Was easy to retrieve a member using GET in FTP, however using PUT in FTP…failed!
Thinking it could be a permission problem, I created my own PDS. And then FTP allowed me to copy a local file to it.
226 Transfer complete
700 bytes sent in 0.00 secs (26.7029 MB/s) Success!
Problem solved…right? Wrong! I tried to copy something else and failed. Then I deleted the very thing (on MVS) above I had successfully copied and I failed trying to copy it back, again! WTH? The error message is cryptic "550 SORT.jcl: Not opened 13" and doesn't help.
Also the MVS shutdown didn't complete…It appears FTP needed to be stopped 1st "/stop ftpd".
