Improving FTP server performance with configurable subsystem support

 

The default subsystem (QSYS/QSYSWRK) is used for many IBM-supplied server jobs. Using a different subsystem than the default subsystem can result in improved File Transfer Protocol (FTP) performance because the need to share resources is eliminated.

To configure a subsystem for the FTP server, follow these steps:

  1. In iSeries™ Navigator, expand your system > Network > Servers > TCP/IP.

  2. Right-click FTP and select Properties.

  3. On the FTP Properties page, select Subsystem description.

  4. Specify a subsystem description and a predefined library.

If the specified subsystem does not exist, then FTP will create it along with routing table entries and job descriptions. When the startup job for the FTP server is started, it will specify the parameters for the newly created subsystem and then submit the server jobs for batch startup in that subsystem.
