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).

Note	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.

The port_range_nodes table has the following structure:

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.
