目标:
将现有的oracle 11.2.0.1 rac升级至11.2.0.3。使用out-of-space方式来升级。使用rolling upgrade方式升级。

rolling upgrade的好处就是:确保至少有一个node是能够对外提供服务的。

If you are upgrading from previous version to 11.2.0.3, notice that upgrade process to 11.2.0.3 has been improved that CVU is used to verify the Oracle prerequisite patches before starting the upgrade.
