Problems solved by technology

This innate defect of network resource competition can easily lead to the actual performance of the Oracle RAC cluster deployed on the public cloud is not high, and even the cluster crash occurs. For example, a well-known domestic public cloud service provider has not officially launched the Oracle database. Cloud service products

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as figure 1 and 2 As shown, the method for deploying a high-performance Oracle RAC cluster on the public cloud of the present invention includes:

[0019] 1. Establish 2 or more virtual servers on the public cloud as Oracle RAC cluster nodes, among which 2-node RAC needs to build another virtual server as the arbitration node.

[0020] 2. Create 3 or 5 storage disks of the same size and mount them to 3 or 5 virtual servers respectively as grid (GRID) disks for storing Oracle RAC-related cluster information;

[0021] 3. Establish 2 or more storage disks of the same size, preferably using high-speed SSD disks or NVMe disks, and mount them to 2 or more Oracle RAC cluster node virtual servers respectively to store database data;

[0022] 4. Configure Storage IP, Pub IP, and Priv IP on the virtual server as an Oracle RAC node, and configure Storage IP on the virtu...

Abstract

The invention discloses a method of deploying a high performance Oracle RAC cluster on a public cloud. The method comprises the following steps of first, creating two or more than two virtual serverson the public cloud and using the virtual servers as Oracle RAC cluster nodes; second, configuring an odd number of storage disks of the same size and mounting the storage disks on the multiple virtual servers separately, and using the storage disks as GRID disks to store Oracle RAC related cluster information; third, configuring multiple storage disks of the same size and mounting the storage disks on two or more than two virtual servers as the Oracle RAC cluster nodes so as to store data of a database; fourth, configuring a Storage IP, a Pub IP, and a Priv IP on the virtual server as the Oracle RAC cluster node; and fifth, mounting all storage disks on other servers with database instances in the Oracle Rac cluster nodes through Storage IP by using an iSCSI protocol.

Description

technical field [0001] The invention belongs to the field of databases, in particular to a method for deploying a high-performance Oracle RAC cluster on a public cloud. Background technique [0002] At present, the internal network resources of public cloud virtual machines cannot be configured exclusively, and are shared by all cloud servers. The internal bandwidth and delay used by the Oracle RAC cluster deployed on the public cloud are very easily affected by the overall network resource shortage. Whether it is the communication synchronization between Oracle Rac nodes or the IO access of high-performance cloud storage, it is highly dependent on stable large network bandwidth (above 1000Mb / s) and low latency of data transmission. This inherent defect of network resource competition can easily lead to the actual performance of the Oracle RAC cluster deployed on the actual public cloud is not high, and even the cluster crash occurs. For example, a well-known domestic public...
