ORA-01578: 处理一例。

警告日志里出现错误：

看看是什么对象损坏了吧：

SQL> SELECT tablespace_name, segment_type, owner, segment_name
  2      FROM dba_extents
  3    WHERE file_id = &fileid
  and &blockid between block_id AND block_id + blocks - 1;  4  
Enter value for fileid: 11
old   3:   WHERE file_id = &fileid
new   3:   WHERE file_id = 11
Enter value for blockid: 2186414
old   4:   and &blockid between block_id AND block_id + blocks - 1

SEARCH_DATA                    INDEX              SEARCHSYS
DR$EQ$DOC_PATH_IDX$X

还是是索引，

既然不能恢复，删除重新建立吧：

set long 9999

 select dbms_metadata.get_ddl('INDEX','DR$EQ$DOC_PATH_IDX$X','SEARCHSYS') from dual；

  CREATE INDEX "SEARCHSYS"."DR$EQ$DOC_PATH_IDX$X" ON "SEARCHSYS"."DR$EQ$DOC_PATH
_IDX$I" ("TOKEN_TEXT", "TOKEN_TYPE", "TOKEN_FIRST", "TOKEN_LAST", "TOKEN_COUNT")

问题解决。
