Our data warehouse return this mysterious result: SQL> select *
2 FROM v$sysstat

  3    WHERE  name  = 'physical reads'
  4    or    name    = 'db block gets'
  5    or    name  = 'consistent gets'

6 ;

STATISTIC# NAME CLASS VALUE

---------- ----------------------------------------------------
        38 db block gets         8   6809493346
        39 consistent gets      8   28857032917
        40 physical reads       8   1.84467440704754E19

Look at the parameter "physical reads" - How it can be so large?
