警告日志里出现错误：

Errors in file /u01/app/oracle/diag/rdbms/r92cfdb/r92cfdb/trace/r92cfdb_smon_22972.trc (incident=361333):

ORA-01578: ORACLE data block corrupted (file # 11, block # 2186414)

ORA-01110: data file 11: '/u01/app/oracle/oradata/r92cfdb/SEARCH_DATA_1.dbf'

偿试恢复：

SQL> select * from v$database_block_corruption;

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
new 4: and 2186414 between block_id AND block_id + blocks - 1

TABLESPACE_NAME SEGMENT_TYPE OWNER
------------------------------ ------------------ ------------------------------
SEGMENT_NAME

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。
