Server dependencies

To ensure optimal performance, you must consider several dependencies when you configure your server.

Dependencies include:

• There must be at least one instance of the policy server.
• There must be at least one policy server defined. You can have a single policy server and create as many domains as you want. When a domain is created, a separate policy database is also created for each domain. The single policy server can access any of the distinct policy databases.
• The policy server manages the policy database.
• There must be only one policy database (master authorization database) in a domain.
• The policy database must be on a highly available policy server with a robust file system.
• Each policy database is subject to a regular backup procedure. The administrator can specify the location for the backup files.
• The policy servers provide authorization database replication services to all other Verify Identity Access servers in the domain that run in local cache mode.
• Each resource manager, such as Verify Identity Access WebSEAL, applies security policy based on information from either the policy database or from a replicated authorization database.
