dataguard环境下使用alter user sys identified by 语句修改主库的sys用户密码时,不会自动更新备库的密码文件。而Oracle Dataguard环境的日志传输安全机制依赖于密码文件,因为备库也需要做相应的修改才可以正常的进行日志恢复。而备库随时有可能成为主库,

dataguard环境下使用alter user sys identified by 语句修改主库的sys用户密码时,不会自动更新备库的密码文件。而Oracle Dataguard环境的日志传输安全机制依赖于密码文件,因为备库也需要做相应的修改才可以正常的进行日志恢复。而备库随时有可能成为主库,因此修改密码后应该将主库的密码文件同步到备库。

首先,停止备库

SQL> shutdown immediate

然后,将主库密码文件覆盖备库的密码文件
最后,启动备库,打开日志实时恢复

SQL> startup mount
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;
