ATTENTION: The controlfile sequence# has now reached 4294967295 (0xffffffff),

根据mos文档20324049.8说明，触发的bug已修复（根据不同数据库版本打补丁即可），需要重建控制文件。因无备份，故手动新建控制文件。

重建控制文件示例：

CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS ARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 8192
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
  GROUP 4 '/home/oracle/app/oracle/oradata/orcl/redo01.log'  SIZE 100M BLOCKSIZE 512,
  GROUP 5 '/home/oracle/app/oracle/oradata/orcl/redo02.log'  SIZE 100M BLOCKSIZE 512,
  GROUP 6 '/home/oracle/app/oracle/oradata/orcl/redo03.log'  SIZE 100M BLOCKSIZE 512,
  GROUP 7 '/home/oracle/app/oracle/oradata/orcl/redo04.log'  SIZE 100M BLOCKSIZE 512
DATAFILE
  '/home/oracle/app/oracle/oradata/orcl/MES_DATA.dbf',
  '/home/oracle/app/oracle/oradata/orcl/sysaux01.dbf',
  '/home/oracle/app/oracle/oradata/orcl/system01.dbf',
  '/home/oracle/app/oracle/oradata/orcl/undotbs01.dbf',
  '/home/oracle/app/oracle/oradata/orcl/users01.dbf',
  '/home/oracle/app/oracle/oradata/orcl/WMS_DATA.dbf'
CHARACTER SET ZHS16GBK
;

启动数据库以后，若报错：

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/home/oracle/app/oracle/oradata/orcl/system01.dbf'

进行恢复，然后继续启动，直至可以正常启动。（仅适用于只有控制文件损坏的情况，日志等皆没问题）

SQL> recover datafile 1 recovery;
ORA-00905: missing keyword


SQL> recover datafile 1;
Media recovery complete.
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01113: file 2 needs media recovery
ORA-01110: data file 2: '/home/oracle/app/oracle/oradata/orcl/sysaux01.dbf'
