进行归档恢复的时候数据库报以下错误：
RMAN-08591: WARNING: invalid archived log deletion policy
查看ORA错误解释：
[oracle@021Y-SH-BKAP ~]$ oerr rman 8591 8591, 3, "WARNING: invalid archived log deletion policy" // *Cause: An invalid ARCHIVELOG DELETION POLICY was supplied. The archived // log deletion policy was APPLIED but there was no mandatory // archived log destinations. // *Action: One of the following: // 1) Change archived log deletion policy using CONFIGURE command // 2) Make one or more of standby destination as MANDATORY.
说明这是由于备库是从主库获取的日志归档，而不是归档的传输者，因此该策略部符合该库的角色，进入rman工具：
