Finding Size of Data in a file (PF or LF)

[AKumar@xxxxxxxx]

Hi All,
     I need to know the exact size of a file (PF or LF) . I am using
DSPOBJD and DSPFD commands. There is difference in size returned by these
two commands.

     Let me explain this to you.

               Result of  DSPOBJD             Result of DSPFD

PF Name :  FILE     size           :682700800                Total of
member sizes : 682659840
               offline size   :681619456

LF Name : FILE1     size      :44077056            Total of member sizes
:44064768
               offline size   :44077056

LF Name : FILE2     size      :28672                    Total of member
sizes :47210496
               offline size   :47239168

LF Name : FILE3     size      :68194304            Total of member sizes
:68182016
               offline size   :67145728

LF Name : FILE4     size      :294912                   Total of member
sizes :262144
               offline size   :294912

File is single membered file. FILE1 , FILE2 , FILE3 and FILE4 are logicals
on FILE.

As I understand, DSPFD.size means cluster size allocated to the file (PF or
LF).  Notice that DSPFD.size is divisible by 8192.
8192 is cluster size.
DSPOBJD. size means size of (Object + Data + Index).
I don't understand DSPOBJD.offline_size.

Questions:
1) Why cluster is allocated to Logical? We know that logical is View or
Access path to Physical.
2) Why the DSPOBJD.size for some logicals are huge? We know that logical
doesn't contain data.
3) For logical FILE2 , there is huge difference in DSPFD.size and
DSPOBJD.size. Why?


Any help is greatly appreciated?
