*********************************************************************
WARNING: The following temporary tablespaces contain no files.
         This condition can occur when a backup controlfile has
         been restored.  It may be necessary to add files to these
         tablespaces.  That can be done using the SQL statement:
 
         ALTER TABLESPACE <tablespace_name> ADD TEMPFILE
 
         Alternatively, if these temporary tablespaces are no longer
         needed, then they can be dropped.

客户的自行恢复到此为止,没有成功,这里客户的恢复没有犯原则性错误(破坏文件的resetlogs 信息),同时也没有解决两个ORA-600错误
1. 在offline部分文件的情况下,打开数据库(没有使用resetlogs,避免了进一步破坏offline文件的resetlogs 信息),但是数据库报ORA-600 4193错误没有打开库成功
2. 后面强制拉库之前重建了ctl文件,避免了offline数据文件在resetlogs之后导致文件头resetlogs 信息和其他文件不一致的可能(因为重建ctl,offline的文件自动onlinne)
3. 最初offline数据文件,启动库报ORA-600 4193故障没有解决,这个故障一般是undo异常导致,这个故障大概率在后面强制拉库open过程中还可能遇到
4. 强制拉库过程中遭遇ORA-600 2662问题,需要修改scn,如果这个问题不解决,数据库无法open成功
