Because of what are mainly RDBMS architectural differences, SAP
recommends frequent reorgs, and even offers programs to do so, for their
DB2 implementations. When I was a db2/Oracle database consultant for a
major oil company, the manager of the group read a document by SAP and
IBM recommending frequent reorgs. Because of that fact, to this day, my
comrades at this company spend one full weekend a month reorging the
Oracle implementations of SAP, even though, in fact, the vendor does not
specifically recommend it for Oracle, nor do they measure to determine
if they receive any gains from the exercise.
I think this falls amound the category of "urban legend" - that a Reorg
of all tablespaces will actually help SAP Oracle performance has never
been proved.
