从oracle官方的角度讲，这种方案是不可以的。如果从野路子出发，不排除可以部署的情况，但是中间碰到一些奇奇怪怪的问题或者bug，可能就解决不了。既然要修复漏洞，建议还是找窗口打补丁吧。

Oracle Patch Assurance - Data Guard Standby-First Patch Apply ( Doc ID 1265700.1 )

However, differences in database home software were limited to rolling upgrade scenarios supported only by logical standby databases. In order to apply a later database home patch (e.g. Exadata bundle patch, or database PSU) to a Data Guard environment with physical standby, you had to perform one of the following actions:

Shutdown both the primary and standby databases and apply the update to both systems before restarting, or
Convert the physical standby database to a logical standby database and apply the update using the rolling upgrade process, then convert the standby database back to a physical standby (a feature known as transient logical standby).

跨版本做不了DG，备库只能到mount 状态。

adg要求同平台同版本

2、如果想达到这个目的，其实可以有多种方案。
