由于希望测试一个DG问题，所以在Vmware上搭建测试环境，primary和standby放在同一台主机上。
搭建过程就不赘述，，但是在最后，遇到了一些问题，这里记录一下，以备后续查阅。
----搭建过程中的一些命令-----
1. backup database format '/tmp/bk_%U';
2. backup current controlfile for standby format '/tmp/stdbyctl.bkp';
3. catalog start with '/tmp/';
4. set controlfile autobackup format for device type disk to '/tmp/%F';
restore standby controlfile from '/tmp/stdbyctl.bkp';
5. RMAN> CONNECT TARGET SYS/oracle@db;
RMAN> CONNECT AUXILIARY SYS/oracle@stddb;
6. 最会std的pfile文件内容
db_file_name_convert= '+data/db/','+reco/stddb/'
log_file_name_convert= '+RECO/db/archivelog/','+RECO/stddb/archivelog_std/'
log_archive_format=%t_%s_%r.arc
standby_file_management=auto
compatible='11.2.0.0.0'
control_files='+RECO/stddb/controlfile/current.260.834947597' 问题一：
在设置listener的过程中，由于设定静态监听，在standby启动之后，同时又会注册一个动态监听，目前有两个监听，其中动态监听状态为blocked。
遇到的问题就是，在duplicate连接的时候，就会发生ORA-12528错误，而不能正常连接到standby。

在执行下面命令之后，直接primary就crash掉，经过查询alert发现，是redo broken导致的
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
查询standby alert，发现如下信息：
（在ALTER DATABASE RECOVER...开始之后，第一件事情就是clear redo log，这样就直接导致primary crash）

在重建几次之后，问题依然。
由于datafile和archivelog都使用convert参数转换了，但是redo是无法转换的，如何解决这个问题呢？
经过分析，发现在duplicate的最后，有一些警告信息：
