and collations settings database is:

 database territory                                      =  database code page                                      = 1208  database code set                                       = utf-8  database country/region code                            = 1  database collating sequence                             = system_1252  alternate collating sequence              (alt_collate) =  number compatibility                                    = off  varchar2 compatibility                                  = off  date compatibility                                      = off  database page size                                      = 4096 

i suppose db2 uses specific algorithms make ordering.

the question how test such ordering using java? there libraries can such string comparisons?

ps: tried collator jdk 6 , icu4j different settings , didn't help.

have looked @ set option srtseq (and possibly langid) in sql reference edition of db2? (luw, z/os, or ibm i)
