異構平臺之間的配置DataGuard的情況說明

在部署DataGuard時，最簡單的情況是主/備節點配置完全相同的。但是，有時會碰巧會有在異構操作系統上進行部署的情況，以便于從異構平臺之間進行數據遷移能有最小的停機時間或風險。為用戶通過配置異構的處理能力或硬件本錢較低的備用系統，以減少在災備上的投資，這也是全理的方案。使用提供這類配置的說明信息，以肯定哪些平臺組合能進行Data Guard的配置，和任何額外的要求或限制是不是在可能適用的范圍。

如果斟酌使用1個異構的主/備DataGuard配置，Oracle建議用戶進行充分的測試，并確保DataGuard能夠實現switchover 或 failover的正常切換。

1.肯定主備庫的 Platform ID

SQL>  select platform_id, platform_name from v$database;

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

只要在被認證的每一個服務器上能運行Oracle的平臺上，安裝了Oracle軟件是相同的，并且是相同的Oracle數據庫版本和補釘集，主服務器和備用服務器之間的差異總是支持。
所支持的這類差異的例子包括以下內容：

• 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. x86⑹4 AMD64 and x86⑹4 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)

上面的差別能被認為是相同的平臺（PLATFORM_ID）


2. 如果主備庫的平臺（PLATFORM_ID）不同，能通過下面的表檢查兩個臺之間是不是能支持配置物理 DataGuard


除支持相同的平臺配置DataGuard之外，通過下表也能夠看到，1些不同的平臺之間也能配置 物理 DataGuard，如Linux x86⑹4和Microsoft Windows (x86⑹4)。

總結：

也能夠看到，從Oracle 11g開始， Oracle能支持某些異構平臺之間的 DataGuard 部署了。
