  • Memory-mirroring control apparatus and memory-mirroring control method
    Patent number: 9612928
    Abstract: When an update instruction for updating task data stored in a memory is transmitted through a transaction process performed by an application server, an active node apparatus generates, based on the update instruction, an update log indicating update contents of the task data stored in the memory, and then distributes, in a multicast manner, the generated update log to other standby node apparatuses each with a memory. With this, mirroring among the plurality of memories is controlled.

  • APPLICATION LINKAGE CONTROL APPARATUS AND APPLICATION LINKAGE CONTROL METHOD
    Publication number: 20090282420
    Abstract: When a message is transmitted from a storing application of a process requesting server, a message queuing server stores the message in a queue. When storing the message in the queue, the message queuing server transmits information regarding this message to an extracting application of a process performing server, thereby controlling a linkage operation between the storing application of the process requesting server and the extracting application of the process performing server.
