Dear gurus,

mohon pencerahannya, di alert log database saya muncul error :
Corrupt block relative dba: 0x00c10f3d (file 3, block 69437)
Fractured block found during buffer read
Data in bad block:
 type: 6 format: 2 rdba: 0x00c10f3d

Reread of rdba: 0x00c10f3d (file 3, block 69437) found same corrupted data

Corrupt Block Found
         TSN = 2, TSNAME = SYSAUX
         RFN = 3, BLK = 69437, RDBA = 12652349
         OBJN = 49871, OBJD = 49871, OBJECT = MGMT_METRICS_RAW_PK, SUBOBJECT
=
         SEGMENT OWNER = SYSMAN, SEGMENT TYPE = Index Segment

saya coba rebuild, tapi ternyata object ini adalah IOT objek,
SQL> ALTER INDEX MGMT_METRICS_RAW_PK REBUILD;
ALTER INDEX MGMT_METRICS_RAW_PK REBUILD
*
ERROR at line 1:
ORA-28650: Primary index on an IOT cannot be rebuilt

so bagaimana cara saya untuk mengatasi corrupted block / index ini ? apakah
dengan re-create IOT ini ? bila memang iya, bagaimana cara nya ?

Many Thanks,
Andes
