Problems solved by technology

The DB2 database in the dual machine can realize data synchronization on the main and standby two machines by configuring HADR to ensure data consistency; but when the main server fails, a corresponding mechanism is required to switch the application to the standby server, so that the standby server Become the main server to take over all services, but the DB2 database does not have a corresponding mechanism to switch between the main and standby servers, although the standby machine can use

Embodiment 1

[0032] A kind of fault detection and switching method of DB2 database based on Itanium platform of the present invention adopts the method that BCP software and DB2 database are combined in the dual machine hot backup based on Itanium platform, realizes fault detection and switching; Through DB2 The HADR feature of the database realizes the consistency of the data in the two machines; the related software and hardware resources are created through the BCP software, and the fault detection and switching of the software and hardware environment are realized.

[0033] Through log synchronization, HADR synchronizes the log files generated by the master node to the standby node, and the standby node synchronizes the received log files to achieve data synchronization with the master node, realizing the data on the two dual-machine hot standby servers. consistency.

[0034] The BCP software creates a resource group, which contains resources, and monitors the content contained in the ...

Embodiment 2

[0038] A kind of fault detection and switching method of DB2 database based on Itanium platform of the present invention, detailed steps comprise:

[0039] (1) Install the DB2 database and BCP software on the KUX system of the two nodes in the dual-machine hot standby of the Itanium platform;

[0040] (2) Configure IP addresses of two different network segments for the two nodes, which are used as public network IP addresses and private network IP addresses. The two nodes are divided into master nodes and standby nodes;

[0041] (3) Create a DB2 database, configure HADR, and start the BCP software service;

[0042] (4) Unzip the BCP software installation package under the Windows operating system environment, open the ClusterManager.jar file of the management client of the BCP software, log in to any node, and create clusters, resource groups and resources in resource groups;

[0043] (5) Upload the cluster created by the management client of the BCP software to two hot standby...

Abstract

The invention discloses a fault detection and switching method of a DB2 database based on an Itanium platform, belonging to the technical field of fault detection of a database. The method of combination realizes fault detection and switching; through the HADR feature of DB2 database, the consistency of data in the two machines is realized; through BCP software, related software and hardware resources are created to realize fault detection and switching of the software and hardware environment. The present invention realizes the monitoring of the DB2 database by using the Inspur BCP software to monitor the relevant process of the DB2 database, so as to ensure the normal operation of the database and the continuous and reliable business.

Description

technical field [0001] The invention relates to the technical field of fault detection of a database, in particular to a fault detection and switching method of a DB2 database based on an Itanium platform. Background technique [0002] The Itanium platform is a platform based on the Itanium processor hardware architecture. The Itanium processor is Intel's first 64-bit product, with 64-bit addressing capabilities and 64-bit wide registers, so we call it a 64-bit CPU. Due to its 64-bit addressing capability, it can use an address space of 1 million terabytes, which is sufficient for computing enterprise-level or very large-scale database tasks; 64-bit wide registers can enable CPU floating-point operations to achieve very high precision. In fact, the IA-64 processor also has features such as explicit parallelism, branch prediction, and speculative loading. These technologies are designed for top-level and enterprise-level servers and workstations. Instruction-level parallelis...
