The QueryEnabler component communicates with DB2 Query Patroller through the DB2 Query Patroller control tables. The command line interface, agent component, and some parts of the server component communicate with the DB2 Query Patroller request server through sockets. To reduce the number of TCP/IP socket connections required, DB2 Query Patroller has a process called iwm_net that runs on the server and agent nodes. The iwm_net process allows communication between components on a single node to communicate with each other using TCP/IP sockets and concentrates all communication between nodes to a single outgoing socket connection reducing the number of TCP/IP socket connections required.
