ServerDeclaration

public class ServerDeclarationStruct
extends java.lang.Object

A ServerDeclaration represents a logical environment where a SAND node can run. Nodes running on separate servers are non-local and must communicate via secure channel using gateways. When running a distributed application, the server declarations describe what servers the system will be running on.

serverID

protected java.lang.String serverID

A unique identifier for this server. When determining which nodes out of a configuration should be loaded for a particular machine, the SAND environment checks the ID of the machine it is running on against this value.

If the SAND_SERVERID environment variable is set, then its value is compared with this value. If the SAND_SERVERID is not set, then the current IP Address is compared with this value. If the direct IP address comparison fails, an attempt is made to convert this value to an IP address through DNS lookup and the comparison is retried.
