通过询问知道由于file#=17最初由于裸设备权限异常,导致无法访问,执行了delete from file$ where file#=17,然后遭遇异常又人工插入了一条file#=17的记录到file$中,但是由于不知道具体值,可能是由于部分值插入错误引起现在问题.

通过分析file$表定义

create table file$                                             /* file table */
( file#         number not null,                   /* file identifier number */
  status$       number not null,                      /* status (see KTS.H): */
                                               /* 1 = INVALID, 2 = AVAILABLE */
  blocks        number not null,                   /* size of file in blocks */
                                           /* zero for bitmapped tablespaces */
  ts#           number,                         /* tablespace that owns file */
  relfile#      number,                              /* relative file number */
  maxextend     number,                                 /* maximum file size */
  inc           number,                                  /* increment amount */
  crscnwrp      number,                                 /* creation SCN wrap */
  crscnbas      number,                                 /* creation SCN base */
  ownerinstance varchar("M_IDEN"),                    /* Owner instance name */
  spare1        number,      /* tablespace-relative DBA of space file header */
                                   /* NULL for dictionary-mapped tablespaces */
  spare2        number,
  spare3        varchar2(1000),
  spare4        date
)

通过dump文件头(文件创建大小/SCN等),结合一些计算和经验值,获取到相关值重新插入正确值,一切恢复正常

delete from file$ where file#=17 and ts#=384;
insert into sys.file$ (FILE#, STATUS$, BLOCKS, TS#, RELFILE#, MAXEXTEND, INC,
 CRSCNWRP, CRSCNBAS, OWNERINSTANCE, SPARE1, SPARE2, SPARE3, SPARE4)
values (17,2,256000,384,17,0,0,3087,1631091037,null,71303170, null, null, null);
commit;

再次提醒,file$中记录请勿人工修改,以前写过相关casefile$ 删除记录恢复(delete file$ recovery)
