  • Patent number: 11785112
    Abstract: It is made possible to realize bidirectional communication safely on the cloud side, and on-premises side in a job execution system. It is checked whether or not there is an agent with the same logical name at time of agent registration. In a case that there is the same logical name, transfer performance required of each agent is checked, and communication is performed by rewriting a logical name during transfer by using an existing logical name for an agent required of the highest transfer performance, and using a logical name which is a new unique alias for the other agent.
