Up to 16 additional subsystems can be configured for WebFacing. If no other subsystems are configured, by default, WebFacing jobs run in the QINTER subsystem. Assess the need for using additional subsystems based on your knowledge of how many users you have and the capabilities of your hardware. Keep in mind that an interactive job is created for each user logon whether the logon is through a 5250 session or a WebFacing session. Note, when additional subsystems are configured for WebFacing, QINTER is no longer used for WebFacing interactive jobs.
WebFacing interactive jobs are named by using a device name convention QQFn* where n represents which subsystem is being used in a sequence of up to 16. The value for n follows hex numbering conventions. In hex, the first 10 values for n are represented with the numbers 0 through 9 and the next six values (values 10 to 15) are represented with the letters A through F. For example, names for jobs in the first subsystem will begin with QQF0*, names for jobs in the twelfth subsystem will begin with QQFB*. If no additional subsystems are configured, WebFacing interactive jobs can be identified in the QINTER subsystem by names beggining with the string QQF0*.
