3 Managing the QIO Subsystem
This section describes several tools provided to verify that your QIO environment is
properly configured. These tools are also useful for troubleshooting your environment.
Managing the QIO subsystem includes the following tasks:

Configuring and starting the QIOMON process.

Observing and controlling the shared memory segment while the subsystem is
running.

Determining how much of the segment is actually used, so the segment size can
be adjusted for optimal system performance.

Limiting how much of the segment each client process can consume. (This task is
performed through the management interfaces for the client processes.)

Starting and stopping tracing of the QIO subsystem to facilitate the investigation
and resolution of shared memory problems.

Displaying statistics for the shared memory segment.
Verifying the Configuration
The SCF INFO MON command with the DETAIL option displays the CPU and
configuration, program, and library file names that were specified when the QIOMON
process was started.
Note. QIO subsystem tracing is not a substitute for protocol tracing, which must be performed by the
client processes.
