#### <> <> <000000> ORA-01110: data file 9: '/home/oracle/OraBase/oradata/QAWEB/datafile/o1_mf_wbxobj_l_5tk3oxx2_.dbf'

java.lang.Throwable: ORA-01578: ORACLE data block corrupted (file # 9, block # 130902)
ORA-01110: data file 9: '/home/oracle/OraBase/oradata/QAWEB/datafile/o1_mf_wbxobj_l_5tk3oxx2_.dbf'

Root Cause: The QA DB shutdown abnormally, it causes to oracle data block corrupted.

Solution:
1.    Check the invalid and broken object

ORA-01578: ORACLE data block corrupted (file # 7, block # ;)
ORA-01110: data file ;: '/oracle1/oradata/V920/oradata/V816/users01.dbf’
其中，＜AFN＞代表坏块所在数据文件的绝对文件号，;代表坏块是数据文件上的第几个数据块
出现这种情况时，应该首先检查是否是硬件及操作系统上的故障导致Oracle数据库出现坏块。在排除了数据库以外的原因后，再对发生坏块的数据库对象进行处理。

SELECT *
FROM dba_extents
where file_id = 9 and 130902 between block_id and block_id+blocks-1

2.    Drop the Index and rebuild it.

###drop the PK of tables

ALTER TABLE TEST.WBXCUSTOMERENROLLFIELDSVALUE
 DROP PRIMARY KEY CASCADE;

###drop the index 

DROP INDEX TEST.PK_WBXCUSTENROLLFLDVALUE;

###create the PK of tables and the index will be built automatically.

ALTER TABLE TEST.WBXCUSTOMERENROLLFIELDSVALUE ADD (
  CONSTRAINT PK_WBXCUSTENROLLFLDVALUE
 PRIMARY KEY
 (FIELDID, ATTENDEEID, SITEID)
    USING INDEX
    TABLESPACE WBXOBJ_LARGE_IDX
    PCTFREE    10
    INITRANS   2
    MAXTRANS   255
    STORAGE    (
                INITIAL          10M
                MINEXTENTS       1
                MAXEXTENTS       UNLIMITED
                PCTINCREASE      0
               ));
