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' <<<<<<在恢复control之前，先设定为control_files='+RECO'恢复之后，根据实际位置更改 db_block_size=8192 processes=150 remote_login_passwordfile='EXCLUSIVE' undo_tablespace='UNDOTBS1' undo_management=auto log_archive_cOnfig='dg_cOnfig=(primdb,stbdb)' log_archive_dest_1='location=+RECO/stddb/archivelog_std/ valid_for=(all_logfiles,all_roles) db_unique_name=stbdb'

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。

通过设置tnsnames.ora，可以解决这个问题。

问题二：

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）

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # tail -f alert_stddb.log Clearing online redo logfile 1 complete Clearing online redo logfile 2 +DATA/db/redo02.log Clearing online log 2 of thread 1 sequence number 5 Clearing online redo logfile 2 complete Clearing online redo logfile 3 +DATA/db/redo03.log Clearing online log 3 of thread 1 sequence number 3 Tue Dec 24 14:32:49 2013 Clearing online redo logfile 3 complete Tue Dec 24 14:32:49 2013 Media Recovery Waiting for thread 1 sequence 4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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：
