What's a few GB among friends?
SELECT sum(ODOBSZ)

SUM ( ODOBSZ )

Anyone referring to the above should keep in mind that use of ODOBSZ
has been deprecated for many years and OS releases. The ODOBSZ column
text has long suggested that for "Object size: 9,999,999,999=Use
ODSIZU*ODBPUN"; the general recommendation is to use that expression
irrespective of the value of ODOBSZ. Using ODOBSZ is especially
undesirable for the object type *JRNRCV, like for the database *FILE,
both being object types which can match or exceed 10GB; i.e. SUM(ODOBSZ)
may provide undesirable results if objects of those types are included
in the aggregate. Thus more appropriately:
select sum(odsizu*odbpun) from qtemp/qadspobj
Or perhaps:
with
szgb (ss) as ( select dec( dec( sum( odsizu*odbpun ), 13 )
/ (1024**3), 9, 3 )
from qtemp/qadspobj )
select char( repeat(' ', 12-length(strip(ss,b)) )
concat ss concat 'GB', 14) as "Total Size"
from szgb
