问题描述：
主库可以借助TNS连接进入，但备库连接不上

问题原因：
备库未安装实例，只借助修改主库pfile中的参数后启动到nomount状态，动态监听识别不到Oracle服务

解决：
修改动态监听为静态监听

ERROR:
ORA-12537: TNS:connection closed

问题描述：
主库修改动态监听为静态监听后借助tns服务连接数据库连接不上，查看监听发现静态监听存在，tnsnames.ora文件未做修改

问题原因：
静态监听配置文件中的ORACLE_HOME有误：1. 路径有误 2. 路径最后多出一个’/’

解决：
修改路径后删除最后的’/'即可

RMAN-05535: warning: All redo log files were not defined properly.

Oracle error from auxiliary database: ORA-01275: Operation RENAME is not

RMAN-05535: warning: All redo log files were not defined properly.

问题描述：
构建备库时建立备库的redo日志报错重命名错误

问题原因：
standby_file_management设置为AUTO
DG模式下文件有两种管理方式（show parameter standby可以查），自动和手动管理，如果是自动管理，是没法做增加和重命名操作的。

解决：
关闭已mount的数据库
重新启动到nomount状态
修改管理方式为MAMUAL
删除备库上相关的文件后重新执行rman语句

shutdown immediate;
startup nomount;
alter system set standby_file_management=MANUAL;
