错误一
SQL> alter database recover managed standby database disconnect from session; alter database recover managed standby database disconnect from session * ERROR at line 1: ORA-01665: control file is not a standby control file SQL> select controlfile_type from v$database; CONTROL ------- BACKUP 原来使用 restore controlfile from '/u02/rman/fyl_1_8.ctl'; 解决：使用如下命令 restore standby controlfile from '/u02/rman/fyl_1_8.ctl';错误二
Check that the primary and standby are using a password file
and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
and that the SYS password is same in the password files.
returning error ORA-16191
解决：copy密码文件 9备忘脚本
