this  query makes only one record but two records should come , the records  coming İS "ŞEFTALİ" the other records
which is written in lowercase  "şeftali" do not come

I just couldn't test it myself, since my database character set doesn't support it, but maybe it's Azerbaijani?You are correct :
SQL> select value from nls_database_parameters where parameter = 'NLS_CHARACTERSET';
VALUE
AL32UTF8
SQL>
SQL> SELECT NLS_UPPER('ali', 'NLS_SORT = XAZERBAIJANI') test_upper
  2  FROM DUAL;
TEST_UPPER
ALİXTURKISH works too :
SQL> SELECT NLS_UPPER('ali', 'NLS_SORT = XTURKISH') test_upper
  2  FROM DUAL;
TEST_UPPER
ALİ
