port_range_active

The port_range_active table lists what port/RPC numbers are being actively used to provide RPC services by iProcess Engine processes.

Note	The table only lists processes that provide RPC services. These processes are RPC_TCP_LI, RPC_UDP_LI, RPC_POOL, RPC_SWIP, WQS and WIS.

Structure

The port_range_active table has the following structure:

TABLE port_range_active (
	logical_machine_id		INTEGER		NOT NULL,
	logical_process_name		VARCHAR(10)	NOT NULL,
	logical_process_instance	INTEGER		NOT NULL,
	process_id			INTEGER		NOT NULL,
	port_number			INTEGER		NOT NULL,
	rpc_number			INTEGER		NOT NULL)

Column	Description
logical_machine_id	ID of the server where this process instance runs, as defined in the node_cluster table.
logical_process_name	Logical name of this process instance. Note: See "Administering iProcess Engine Server Processes" in TIBCO iProcess Engine Administrator's Guide for a list of logical process names.
logical_process_instance	Unique ID for this process instance.
process_id	Operating system process ID of this process instance.
port_number	Port number being used by this process instance.
rpc_number	RPC number being used by this process instance.

Primary Key

The following primary key is defined for this table.

Key Name	Column(s)

Table Activity

The port_range_active table contains one row per port/RPC number that is being actively used by the iProcess Engine.

Rows are added, updated and deleted in the following situations.

A row is...	When...
added	an iProcess Engine process allocates itself a port/RPC number from either the port_range table or the operating system.
updated	never.
deleted	an iProcess Engine process stops using its assigned port/RPC number, that is, is shut down.
