Internal Process Handling

• Find destination Server and Node is the process of finding a matching entry for the destination RPC server in the server port specification file.
• Regular RPC Lookup is the process of querying the endpoint mapper on the destination system.

Some of the decisions made in the flow chart above are implemented by evaluating opcinfo variables on managed nodes or registry keys on the management server:

• Port file configured? Controlled with OPC_COMM_RPC_PORT_FILE
• Endpoint mapper lookup enabled? Controlled with OPC_COMM_LOOKUP_RPC_SRV
• On managed node? Will be answered with yes by all RPC clients running on the managed node. These are opcmsga, opcdista and opcagt.
• Opcinfo variable set? Will be answered with yes if the RPC clients want to connect to either of the following RPC servers (then, if set, the value of the according variable will be used by the RPC client as port of the destination RPC server):

  RPC Server	Key
  Message receiver interface of the message action server	OPC_COMM_PORT_MSGR
  Distribution manager interface of the message action server	OPC_COMM_PORT_DISTM
  Local Control agent (opcctla)	To access the local control agent, the client reads the setting used by the local RPC server, the control agent opcctla: (OPC_RESTRICT_TO_PROCS opcctla) OPC_COMM_PORT_RANGE …
