Other Ways to Manage Memory Space Without Moving QIO
QIO provides three methods of solving memory-conflict problems that do not involve
running QIO in system data space:

You can configure QIO to create its memory segment space with a different starting
base address. This allows more room for the process heap to grow.

You can change the size of the QIO shared memory segment to allow more room
for the process heap and flat segment memory space to grow.

You can change individual processors to different configurations independently of
one another to tailor processor configuration to program requirements.
Before You Begin
Before you begin to configure QIO, ensure that you are taking the correct approach for
your system. For guidelines on memory management, see Memory Management on
page 2-5. In evaluating memory management situations, you must first know the
maximum memory that QIO is using. The information is available in the Max Pool Size
field displayed by the STATUS SEGMENT, DETAIL command.
Determining the Maximum Pool Size
To find the maximum size of the pool space you need in QIO shared memory, use the
STATUS SEGMENT, DETAIL command as follows:
-> status segment $zm**, detail
