Property value substitution
In an environment with multiple PingGateway servers, use property value substitution for similar but different configurations across the servers.
Property value substitution enables you to:
-
Define a configuration specific to a single instance; for example, setting the location of the keystore on a particular host.
-
Define a configuration whose parameters vary between different environments; for example, the URLs and passwords for test, development, and production environments.
-
Disable certain capabilities on specific nodes.
Property value substitution uses configuration tokens for variables in the server configuration. The substitution follows a process of token resolution, JSON evaluation, and data transformation. The following pages describe this in detail.
