Embodiment Construction

[0021] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0022] figure 1 It is a schematic structural diagram of an embodiment of the dual-machine system of the present invention, such as figure 1 As shown, the two-machine system includes an upgrade module, a switching module, a main machine and a backup machine. In this embodiment, machine No. 0 is the current main machine, machine No. 1 is the standby machine, and machine No. 0 and machine No. 1 are two configurations same machine. Among them, No. 0 machine is the main machine, and its database can initiate data changes, and synchronize the changed data to the database of No. 1 machine as the backup machine through the data synchronization mechanism; and No. 0 and No. 1 machines can use the application synchronization mechanism Synchronize the changed applications to each other. The databases of No. 0 machine an...

Abstract

The invention embodiment discloses a dual system and the dual on-line upgrading method. The dual system consists of an upgrading module, a switching module, a host machine and a standby machine. The dual on-line upgrading method includes: the upgrading for the host machine and the standby table corresponding to the main use table in the standby machine database; the upgrading for the application program of the standby machine; the switching for the application program and the database of the host machine and the standby machine; the switching for the main use table and the standby table in the standby machine; and the upgrading for the application program of the host machine. The dual system and the dual on-line upgrading method aim at stopping the outward service providing when switchingthe host machine and the standby machine as well as switching the main use table and the standby table in the standby machine, the stopping time for the outward service providing is reduced, and the influence for the service normal operation is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the dual-computer technology, and in particular to a dual-computer system and a method for online upgrade of the dual-computer. Background technique [0002] With the development of telecommunication technology, dual-computer technology is used in telecommunication application system as a reliability technology. For the servers that store important data, dual-computer backup must be adopted to ensure the safe operation of the entire telecommunication application system. In the telecom application system, two machines with the same configuration form a dual-machine system. The machine that provides external services is called the main machine, and the other machine in the backup state is called the standby machine. When the main machine fails to provide external services due to an abnormality, The standby machine automatically determines that the host is abnormal, and performs a dual-machine switch, and...
