Stand-alone PolicyCenter servers

If you enable external server configuration on a stand-alone PolicyCenter server, PolicyCenter performs a series of steps in working with placeholders:

1. Initially, at server start, PolicyCenter reads the affected configuration files, once, during one of the various phases of server start-up.
2. The PolicyCenter Substitutor process then performs an in-place substitution step on all affected configuration files.
3. Finally, PolicyCenter parses the contents of the modified configuration files and stores the results in memory.
