which version of oracle u r running?Just see following output
SVRMGR> connect internal;
Connected.
SVRMGR> select sum(value) from v$sga;
SUM(VALUE)
----------
1033101472
1 row selected.
SVRMGR> select sum(bytes) from v$sgastat;
SUM(BYTES)
----------
1033044248
1 row selected.
SVRMGR> show sga
Total System Global Area 1033101472 bytes
Fixed Size 73888 bytes
Variable Size 537395200 bytes
Database Buffers 491520000 bytes
Redo Buffers 4112384 bytes
If u see all three output you can see the diffrence.The correct view to
check size of sga is v$sga.
Hope this will help u.
Thanks
