Understanding the Configuration File
This command results in a display similar to the following example:
In this NonStop S-series server display, the maximum pool size (Max Pool Size) for
both processor 00 and processor 01 is less than 128 MB, so moving the QIO memory
to Kseg2 is possible.
The default pool size is 16 MB.
For more information on the memory pool, see Subsystem Architecture on page 1-3.
Understanding the Configuration File
Before you begin to take steps to resolve the memory problems, you need to
understand the configuration file.
You can change the specifications of the QIO memory segment by using a
configuration file. This section describes the configuration file and its attributes.
The configuration file is an EDIT file (file code 101). It contains attributes that define the
QIO environment. If no configuration file is configured, the default values of the
configuration attributes are used.
