Like many companies, we use a z/OS guest at IBM Dallas for our testing. We also cross-compile our source on Windows, using the Dignus compiler. Obviously, this results in lots of FTPing bits from our systems to Dallas. Moreover, we do tons of automated testing submitting jobs and gathering output directly to and from the JES queue with FILETYPE=JES.
Usually this all works fine. Some days, however, are a disaster, with FTP hanging constantly, both during "traditional" file transfers and when communicating with the SPOOL via FILETYPE=JES. We've been unable to identify any commonality to the bad days. At various times we've suspected shortage of SPOOL space; something latent in not having IPLed recently (we do wind up IPLing fairly frequently, due to running out of reusable address spaces after stopping and restarting our cross-memory STC repeatedly); shortage of initiators; and other things along those lines, but have always been able to disprove those theories. For example, today, with only two of us around (and thus even more control than usual), is a bad day: test jobs keep hanging in FTP. We reIPLed, and SPOOL and initiators are fine, but the hangs continue. We've talked with IBM and our own IT, and nobody seems to have any clue about how to diagnose this. Any ideas? It's not only frustrating, but when we're on a release deathmarch, is particularly disruptive to schedules!
