Oracle数据库云服务

Oracle数据库云服务使您能够在云中快速部署Oracle数据库,每个数据库部署包含一个Oracle数据库或由Primary Oracle数据库和Standby Oracle数据库组成的Oracle Data Guard配置。创建数据库部署时,Database Cloud Service使用各种Oracle Cloud基础结构服务提供的计算,存储和网络资源创建计算节点以托管数据库,以简化日常数据库维护和管理操作您可以完全访问Oracle数据库提供的功能和操作。


数据库部署完成后,会启动数据库。可以设置数据库自动备份。具有root权限和对Oracle数据库的完全管理权限,可以对自动维护设置进行任何更改。


与许多Oracle云平台服务一样,数据库云服务依赖于名为Platform Service Manager(PSM)的Oracle云的底层组件来提供其服务控制台及REST API。Oracle Cloud的Platform Service Manager(PSM)组件使用SSH访问组成数据库部署的计算节点,以便执行预定义的Platform Service操作,如备份和修补等。您可以从Web控制台或REST API启动这些Platform Service操作。每个数据库部署使用单独的SSH密钥对来执行此内部通信。密钥仅在程序控制下使用,Oracle员工无法直接访问。由计算节点上的Platform Service Manager(PSM)组件执行的所有SSH操作都将被记录并可以进行审计。除非您明确提供对密钥的访问以进行故障排除,否则Oracle云操作团队无法访问驻留在您的计算节点上的任何SSH密钥,也无法访问您的计算节点。


数据库云服务的云工具
除了基于Web的Oracle数据库云服务控制台的功能外,数据库云服务还提供了以下工具:
    简单的自动备份:使用bkup_api实用程序(使用Oracle Real Application Clusters的部署中的raccli)执行按需备份并更改自动备份的配置方式。
    简单的自动恢复:使用dbaascli实用程序的orec子命令(使用Oracle Real Application Clusters的部署上的raccli)从备份进行恢复。
    简单的自动修补:使用dbaascli实用程序的patch子命令(在使用Oracle Real Application Clusters的部署上使用raccli)来应用修补程序。

    SQL Developer Web:使用基于Oracle SQL Developer Web浏览器的应用程序来监视Oracle数据库和计算资源。

Oracle数据库云操作系统用户

用户名 描述

opc

The system administrator account you use to connect to the compute node using SSH. This user can use thesudocommand to perform operations that require root-user access.

oracle

The Oracle Database administrator account you use to access the system and perform non-root database administration tasks. A home directory,/home/oracle, is created for this user. This user cannot use thesudocommand to perform operations that require root-user access. Additionally, by default you cannot connect as this user to the compute node using SSH. You can add the public key to the user’s$HOME/.ssh/authorized_keysfile to grant persistent SSH access, or you can connect as theopcuser and then use thesudo -scommand to start a root-user command shell, followed by ansu - oraclecommand to switch to theoracleuser.

grid

The Oracle Grid Infrastructure administrator account you use to perform ASM, ACFS, and clusterware administration tasks. A home directory,/home/grid, is created for this user. This user cannot use thesudocommand to perform operations that require root-user access. Additionally, by default you cannot connect as this user to the compute node using SSH. You can add the public key to the user’s$HOME/.ssh/authorized_keysfile to grant persistent SSH access, or you can connect as theopcuser and then use thesudo -scommand to start a root-user command shell, followed by ansu - gridcommand to switch to thegriduser.

root

The root administrator for the system. You do not have direct access to this account. To perform operations that require root-user access, use thesudocommand as theopcuser.

云上Oracle数据库监控工具

截至2018年5月,Oracle DBaaS Monitor已退役,开始使用Oracle SQL Developer Web。 从2018年5月开始,单实例数据库的新Oracle数据库云服务数据库部署包括SQL Developer Web而不是DBaaS Monitor。 如果您有较旧的数据库部署,则应尽快将DBaaS Monitor替换为SQL Developer Web。

Features of SQL Developer Web

通过本地数据库管理工具oracle-dbcs-cli管理云上数据库
您可以在本地Linux计算机上使用oracle-dbcs-cli实用程序连接到Oracle Cloud,并在Oracle Database Cloud Service部署上执行各种生命周期和管理操作。当前这个工具不支持Oracle Real Application Clusters的数据库部署。要运行oracle-dbcs-cli实用程序,请首先导航到安装该实用程序的目录。 然后运行以下形式的命令

./oracle-dbcs-cli -help | -ver | subcommand subcommmand-options


注意:请勿使用halt,shutdown或shutdown -h命令关闭计算节点。 这样做将无限期地停止计算节点,并且需要Oracle Cloud系统管理员手动干预才能重新启动计算节点。
