sun cluster3.0下的oracle从ha方式改为rac方式需要重装os和cluster软件么？

可以不重装 os 及 cluster, 但是你要冒风险，而且花的时间精力可能比\r\n一切重来还要大。下面是一个粗略的步骤：\r\n\r\n1. backup oracle\r\n2. disable and offline all resources and resources groups\r\n3. remove all  resources and resources groups\r\n4. deport all disk groups if share groups were made by raw devices\r\n5. remove oracle software\r\n6. remove volume manager software\r\n7. install cluster volume manager\r\n8. install ORCLudlm\r\n9. import all disk group with share mode\r\n10. install oracle RAC\r\n11. config RAC in cluster
