Deciding whether to use restricted or unrestricted stacks
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.
