可以在新平台的机器上建立standby数据库,通过归档文件保证2边数据库的同步,割接的晚上把standby库改成正式库就可以了
呵呵 不好意思 自己纠正一下错误,经过阅读9i的手册Data Guard Concepts and Administration,有下列描述:
1.8 Operational Requirements
The hardware and operating system architecture on the primary and standby
locations must be the same. For example, this means a Data Guard
configuration with a primary database on a 32-bit Sun system must have a
standby database that is configured on a 32-bit Sun system. Similarly, a primary
database on a 64-bit HP-UX system must be configured with a standby database
on a 64-bit HP-UX system, a primary database on a 32-bit Linux on Intel system
must be configured with a standby database on a 32-bit Linux on Intel system,
and so forth.
确认了异构平台是不行的;
不过还有一个思路,把新的数据库存储挂接到楼主的linux机器上,然后逐步做每个lvm卷同步,不过好像每次同步要宕库,而且对源主机cpu占用有影响; |
