  • Publication number: 20260010398
    Abstract: A relay system transfers, upon receiving a first request that specifies first identification information of a job to request the start of execution of the job, from a first job management apparatus, the first request to a job execution system, receives returned second identification information, and stores the first identification information and the second identification information in association with each other in a storage unit. The relay system transmits a third request that specifies the second identification information to request status information, to the job execution system, and stores returned status information in association with the first identification information in the storage unit. When the first job management apparatus stops operation, a second job management apparatus takes over, from the first job management apparatus, a monitoring process of transmitting, to the relay system, a request that specifies the first identification information to request the status information.
