ORA-00331: log version 11.2.0.0.0 incompatible with ORACLE version 10.2.0.3.0

今天做了一个数据库迁移的工作，从 oracle 10g （单实例）迁移到 oracle 11g（ADG），在备库开启应用日志的进程后，告警日志出现了以下错误：

Managed Standby Recovery not using Real Time Apply

日志的版本不兼容，回想起来好像pfile中 有个  compatible 参数，是不是两边设置不同导致.

查了之后发现主库  compatible  ：11.2.0.0.0

备库： compatible  ：10.2.0.3.0

将备库改成和主库一样，重启备库，问题解决。
