Oracle Database Discussions

Hi,
in 10g R2 , I have this in alertlog :

ORA-01578:datablock altered(file # 3, bloc # 30029)
ORA-01110: file 3 : 'D:\BASE\RPRMAN\SYSAUX01.DBF'

Then I try to find the corrupted table :

SQL> SELECT tablespace_name, segment_type, owner, segment_name
  2         FROM dba_extents
  3          WHERE file_id = 3
  4   AND 30029 BETWEEN block_id AND block_id + blocks - 1;
 
TABLESPACE_NAME                SEGMENT_TYPE       OWNER
------------------------------ ------------------ ---------------
SEGMENT_NAME
-----------------------------------------------------------------
SYSAUX                         TABLE              SYSMAN
MGMT_SYSTEM_PERFORMANCE_LOG

Then it is MGMT_SYSTEM_PERFORMANCE_LOG table.
But when I query that table :

SQL> select count (*) from sysman.MGMT_SYSTEM_PERFORMANCE_LOG;

  COUNT(*)
----------
      3342

Is ithe table realy corrupted ?
Thank.
