Consider the following when planning to run one or more Policy Servers in a Solaris 10 environment:
Running a Policy Server in either the global zone or the whole-root non-global zone is supported. Whole-root zones increase configuration flexibility, but increase resource usage because they do not share directories.
Note: The Policy Server is not supported on Sparse-root zones.
Running multiple Policy Server instances, on multiple whole-root zones is supported. However, consider that only one Policy Server instance is supported in each whole-root or global zone.
