IBM Software Group | Tivoli software What is an Extended Agent? q An extended agent (x-agent) is a system or application that is dependent on its Fault Tolerant Agent host to receive scheduling instructions q IBM TWS accepts information from the x-agent q The Interface between IBM TWS and an x-agent is called the access method q Extended Agents and Access Methods are fully documented in the “X -Agent Programmer’s Reference” © 2010 IBM Corporation

IBM Software Group | Tivoli software Application Extensions – Configuration Files Whenever an access method is launched, it reads some configuration files which customize its execution. Usually this files are: § options file (method. opts and XACPU_method. opts) § trace properties file (method. properties) § return code mapping configuration files (method-type. rcm and XACPU_method-type. rcm) Some methods could read additional files. Note: Any change to those files will affect any further access method process: a running access method will not be aware of any change made after its execution. © 2010 IBM Corporation
