System Resources

Oracle 12c Multitenant整合数据库 多租户架构简化整合操作,提高整合密度

Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |

Oracle 使用多租户数据库架构的目的

•降低成本 •数据以及代码更容易且更快捷地移动 •更容易管理和监控 •数据和代码分离 •更少的修补程序和升级

Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |

DB12c多租户架构简化数据库升级及补丁维护 只需一次更改,所有可插拔数据库均会更新

$$$

更快的OLTP混合工作负载

透明: 无需改变应用

更合理的成本效益

Oracle Database In-Memory Goals 目标

100倍

9

$ 2-10倍 简单

实时分析获得几个数量级的性能

提升

Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |

在此之前,客户需要选择适合存储格在此之前, 客户必须选择行或列其中的一种,牺牲另一方面的性能

Oracle 12c:两种数据存储格式并存

10

行式

在行格式下事务处理运行快 – 快速处理少量行,多个列 – 例如:插入或者查询一个销售订单

列式

在列格式下分析的更快 – 快速处理少量列、大量行

– 举例:基于于销售汇总的报表

ORDER

SALES

特性三:分片技术

11

Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |

• 每个分片具有独立的cpu,内存和硬盘

• 使用分片key进行分片 (i.e. account_id)

• 对应用来说,逻辑上就是一个数据库

12

Oracle Sharding – 一种数据库架构模式

只有单一物理数据库,无法进行表的分片

Server

可以在不同的数据库之间对表进行水平分片

Server A Server B Server C

不带sharding技术的数据库 带sharding技术的数据库

Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |

Oracle Database 12c Release 2 提供分片选择
