For instructions on installing and starting the TIBCO Hawk Event Service, see TIBCO Hawk Installation, Configuration, and Administration Guide.The microagent COM.TIBCO.hawk.microagent.HawkEventService exposes the following asynchronous methods:
•
• For more information on these methods, see the TIBCO Hawk Microagent Reference.
• HawkAgentInfo. The events onAgentAlive, onAgentExpired, onMicroAgentAdded, onMicroAgentRemoved, onRulebaseAdded and onRulebaseRemoved add rows to this table.
• For TIBCO Rendezvous transport, the Fault tolerance is implemented using TIBCO Rendezvous Fault Tolerance (TRFT). Each instance of a TIBCO Hawk Event Service process joins a fault tolerant group named HawkEventService:hawkdomain, where hawkdomain is the value of the -hawk_domain command line option.To rank the members of a group, fault tolerance software sorts the members by weight. Weight is assigned using the -ft command line option. The member with the highest weight receives rank 1 (so it outranks all other members). When an instance fails, the next-highest instance is activated and the member with the next highest weight receives rank 2; and so on. When two or more members have the same weight, fault tolerance software ranks them in a way that is opaque to programs.
