    The Connection Pool Manager controls telnet connection pools between QXI and your QAD Enterprise Applications and other application sessions. Each connection pool is identified by the type of user it serves—UI API, JITSAPI, SIAPI, or FinAPI—and by a pool name, the host machine and port, and a system user.
    Each connection pool consists of a minimum and maximum number of connections, and supports several timeout checkpoints. When QXI starts, the active connection pools are started automatically. A pool with a minimum of five and a maximum of fifteen connections automatically creates the first five connections and keeps them idle awaiting connection requests from the identified user.
    When a request arrives, one of the five connections is handed to the requester. That connection moves from the idle state to allocated and then to busy. The Connection Pool Manager then initializes another connection so that, as long as possible within the maximum, there are always five open connections available to incoming requests.
    Each incoming QXI request specifies a receiver—a specific QAD Enterprise Applications instance. You define one API connection pool for each receiver—the pool name is the same as the receiver name. As requests arrive, the receiver is matched with the appropriate connection pool, and a connection is assigned for the transmission of a QDoc.
    Use the Connection Pool Manager to:
    Add and configure a new QXI connection pool.
    View, close, restart, modify, or delete a connection pool.
    View and manage current connections by state.
    View and manage current user sessions.
