异构平台之间的配置DataGuard的情况说明

2024-11-12 21:44:39   202人阅读

在部署DataGuard时，最简单的情况是主/备节点配置完全相同的。但是，有时会碰巧会有在异构操作系统上进行部署的情况，以便于从异构平台之间进行数据迁移能有最小的停机时间或风险。为用户通过配置异构的处理能力或硬件成本较低的备用系统，以减少在灾备上的投资，这也是全理的方案。使用提供这种配置的说明信息，以确定哪些平台组合能进行Data Guard的配置，以及任何额外的要求或限制是否在可能适用的范围。

如果考虑使用一个异构的主/备DataGuard配置，Oracle建议用户进行充分的测试，并确保DataGuard能够实现switchover 或 failover的正常切换。

1.确定主备库的 Platform ID

SQL>  select platform_id, platform_name from v$database;

PLATFORM_ID PLATFORM_NAME
----------- --------------------------------------------------------------------------------
         13 Linux x86 64-bit
         

只要在被认证的每个服务器上能运行Oracle的平台上，安装了Oracle软件是相同的，并且是相同的Oracle数据库版本和补丁集，主服务器和备用服务器之间的差异总是支持。
所支持的这种差异的例子包括以下内容：

  • Hardware manufacturer (e.g. Dell and Sun or Hitachi and EMC)
  • Hardware configuration (e.g. number of CPUs, amount of RAM, storage configuration, etc)
  • Processor (e.g. x86-64 AMD64 and x86-64 Intel 64; POWER4 and POWER5) 
  • Operating system distribution (e.g. Red Hat Linux, SUSE Linux or Oracle Enterprise Linux)
  • Operating system version (e.g. Windows 2000 and Windows XP)

上面的差别能被认为是相同的平台（PLATFORM_ID）


2. 如果主\备库的平台（PLATFORM_ID）不同，能通过下面的表检查两个台之间是否能支持配置物理 DataGuard


除了支持相同的平台配置DataGuard以外，通过下表也可以看到，一些不同的平台之间也能配置 物理 DataGuard，如Linux x86-64和Microsoft Windows (x86-64)。

总结：

也可以看到，从Oracle 11g开始， Oracle能支持某些异构平台之间的 DataGuard 部署了。
