Many installations will find it easier to run a single unrestricted
stack on each z/OS® system.
The following situations might require you to run one or more restricted
stacks on a given system:
- Your installation has administrative requirements that prohibit
the use of stacks that allow sockets with different security labels.
- You must allow applications to communicate with applications on
a multilevel secure system that is not a z/OS system.
- You must allow applications to communicate with applications on
a z/OS multilevel secure system
that is not z/OS V1R5 or later.
- Your stacks are not on the same system and are not members of
the same sysplex.
