做实验时，在bcpserver虚拟机的以下目录建选黑的文件：
Screenshot.png

文件内容：
  1. 192.168.0.11  192.168.0.4 192.168.0.8 192.168.0.10  192.168.0.87
复制代码
对自己的环境执行实验破坏，命令是：
  1. [root@station90 ~]# bcl --O11g05 6b
复制代码

删除表空间的恢复，如果不把控制文件restore，只是做了时间点恢复，必然出现uname000X的错误：
  1. RMAN> run {
  2. 2> sql "alter session set nls_Date_format=''YYYY-MM-DD:HH24:MI:SS''";
  3. 3> set until time '2018-05-19:19:44:46';
  4. 4> restore database;
  5. 5> recover database;
  6. 6> }

  8. using target database control file instead of recovery catalog
  9. sql statement: alter session set nls_Date_format=''YYYY-MM-DD:HH24:MI:SS''

  11. executing command: SET until clause

  1. select  * from v$flashback_database_stat;

  3. select  * from v$restore_point;

  5. create restore point rsp1;
