Route FTP and SMTP Workloads to Their Own Subsystem

Way back in V5R1, IBM introduced the ability to route FTP and SMTP workloads to their own subsystems. By default, FTP and SMTP server jobs run in the QSYSWRK subsystem, along with a lot of other IBM i server jobs. The Server Table in the IBM i Knowledge Center documents all the IBM i server jobs along with the default subsystem in which they run. The server table does state the subsystem is configurable for these servers, but it doesn’t give you any more information.

Subsystem Configuration Documentation

Some of you may have read the subsystem configuration experience reports that were written way back in 2004, which was about when V5R3 became available. The experience reports were under the related information section of the Work Management topic. The subsystem configuration experience reports were covered in three sections:

  • Why multiple subsystems are important, along with how to configure subsystems for server jobs
  • How to configure interactive subsystems
  • How to manage server jobs

In the past, you could not copy a spooled file when it was still open; if you attempted the copy, it would fail with CPF3482, “Copy request failed. Spool file &1 is open.” The spooled file had to be completed before the copy would be allowed.

With IBM i 7.3, you can now copy an open spooled file.

Displaying Open Files with Work Job
