Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0036] In the present invention, the storage device is mounted on the host, and the methods used for mounting the storage device include iscsi, FC, FCoE or IB. In this embodiment, the iscsi storage technology is taken as an example to illustrate, and the oracle database is built in the storage device iscsi volume, which can reduce the dependence on the host, realize data security and integrity, create instances and table spaces, and configure oracle to archive mode, and then install the snapshot agent for database monitoring.

[0037] like figure 1 As shown, the storage device 2 is ...

Abstract

The invention relates to a snapshot-based Oracle database protection method. The method includes the steps: a host mounts a storage device and mounts an Oracle database in the storage device; a client transmits a snapshot request to the storage device according to a snapshot task; on receiving the snapshot request, the storage device transmits a corresponding file path to a snapshot agent; the snapshot agent converts the received file path into a VOLID corresponding to a storage volume according to a registration file; on receiving the VOLID, the storage device acquires a corresponding VOLNAME and transmits a Confirm request to the snapshot agent; the snapshot agent judges whether or not a current database instance can be backuped; if yes, a state of the database instance being uniform is retained, after a snapshot operation is executed, the storage device transmits a Remove request to the snapshot agent to remove the state of the database instance being uniform. Compared with the prior art, the method has the advantages of low dependence on the host, high data safety, high reliability and the like.

Description

technical field [0001] The invention relates to the interdisciplinary technical field combining computer storage technology and data management technology, in particular to a snapshot-based oracle database protection method. Background technique [0002] Data protection has always been an important research field of computer storage technology and data management technology. Since early humans used stone carvings, bamboo sticks and parchment scrolls to record information, data storage has been passed down as a means of knowledge acquisition and communication. [0003] Data storage has been continuously developed from papermaking technology, printing technology, laser printing, and then paper tape, floppy disk, hard disk, and optical disk. With the advent of the information age, people have more and more requirements for data security and reliability. come higher. As one of the current mainstream client / server or B / S architecture databases, oracle database has become an urg...
