A$$uming you mean 'traditional' is FTP of DSN/file to other DSN/file? Ie, just a file/dsn copy from one machine to other? Are you also having issues with jobs submitted via FILETYPE=JES? I mean, jobs are running at good speed or not? Are you also having trouble reading the job results back in FTP session? Are you having problem with ONE FTP session at a stage or only when you have many running at one stage? Some possible guesses: Don Poitras : packet trace. Gord Tomlin : MTU size? Chris Webster : PASV and firewalls. (I would also try that out first, especially that firewalls!!!) Others may chime in? Myself: Check your priority of the STC address spaces (FTP sessions as well as TCPIP stack + FTP server + JES2) used in FTP (if inbound from other to your JES2). For JES2: Check that you have enough initiators, Local Buffers, JOBCLASS priority. Perhaps serious JES2 tuning is needed? Are you having problems from what side? I mean, inbound, outbound, where is the FTP session originally started? ENQ problems? RACF violations? What do you see in JES2MON? What delays do you see in RMF? Are you having problem with that JES2 only or with other JES2 too? Do you have any TCP/IP Policy rules (IBM product 5694-A01)? > We reIPLed, and SPOOL and initiators are fine, but the hangs continue. What messages do you see in TCP/IP stack(s) and FTP server and SYSLOG? >Any ideas? It's not only frustrating, but when we're on a release deathmarch, >is particularly disruptive to schedules! Please post sample problematic FTP JCLs and scripts here on IBM-MAIN. Of course I may missed something obvious to help you. Note: Try using automation to submit jobs as an alternative to get your scheduling up to date. HTH and good luck!
