port_range_nodes

The port_range_nodes table lists which port range configurations (as defined in the port_range_conf table) are being used by which machines in the iProcess Engine node (as defined in the node_cluster table).

It is not mandatory for each machine in an iProcess Engine node to have to sit behind the same firewall. Different machines may use different firewalls, or no firewall.

Structure

The port_range_nodes table has the following structure:

TABLE port_range_nodes (
port_range_id INTEGER NOT NULL,
logical_machine_id INTEGER NOT NULL)

Column	Description
port_range_id	ID of a particular port range configuration, as defined in the port_range_conf table.
logical_machine_id	ID of the server using this port range configuration, as defined in the node_cluster table.

Primary Key

The following primary key is defined for this table.

Key Name	Column(s)
pk_port_range_nodes	port_range_id, logical_machine_id

Foreign Keys

The following foreign key is defined for this table.

Key Name	Column(s)	Referenced in Table...
fk_port_range_nodes	port_range_id	port_range_conf

Indexes

None.

Table Activity

The port_range_nodes table contains one row per server that sits behind a firewall (port range configuration) defined in the port_range table.

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

A row is...	When...
added	a user adds a machine to the list of servers that sit behind a particular port range configuration, using the SWDIR\util\swadm utility.
updated	a user moves a machine from sitting behind one particular port range configuration to another, using the SWDIR\util\swadm utility.
deleted	a user removes a machine from the list of servers that sit behind a particular port range configuration, using the SWDIR\util\swadm utility.
