Problem with PLSQL dbms job in apex

Question

Hi,
I am completely new to apex, and am facing a issue which i feel is strange.
There is a button on the apex page and a process is associated with that button. Some tables are being updated in the code written in that process and a db procedure is called which creates some files on the unix box(utl_file). The type of that process is PLSQL DBMS job.
Now its been observed that the code written on that button is executed at odd times i.e no one made any action on the button.
So my questions are,
Is this PLSQL DBMS job same as that of the database dbms_job?? but the logs have no entry.
Is there a case when the button might be pressed earlier but the job executed late because of resources not being available?
Any logs created by apex so that i can track the job??
Any idea if i can replace this plsql dbms job with any other process type??
Secondly, there are 4 files being generated out of which 3 are generated with 644 permission and 1 file is generated with 600. Why does this happen?
Apex version :3.1
db version: 10.2.0.4

Looks like it's still a database bug. In 10.1.0.4, I get the correct results in sqlplus from the query but I get incorrect results in sqlplus if I do it like this:set serveroutput on
declare
    l_cursor    integer := DBMS_SQL.OPEN_CURSOR;
    l_desc_tbl  DBMS_SQL.DESC_TAB2;
    l_ignore    number;
    l_col_cnt   integer;
    l_col_val   varchar2(32767);
BEGIN
    DBMS_SQL.PARSE(l_cursor,
'select connect_by_isleaf LEAF,DESCRIPTION,PLACE from test_tab start with id = 1 connect by prior id = id_master',
        DBMS_SQL.NATIVE);
    l_ignore := DBMS_SQL.EXECUTE(l_cursor);   
    DBMS_SQL.DESCRIBE_COLUMNS2(l_cursor, l_col_cnt, l_desc_tbl );
    for i in 1 .. l_col_cnt loop              
        DBMS_SQL.DEFINE_COLUMN(l_cursor, i, l_col_val, 32767 );
    end loop;
    while (DBMS_SQL.FETCH_ROWS(l_cursor) > 0)
    loop
        for i in 1 .. l_col_cnt loop
            DBMS_SQL.COLUMN_VALUE(l_cursor, i, l_col_val);           
            -- print the column value
            dbms_output.put_line(l_col_val);
        end loop;
        dbms_output.put_line(chr(10));      
    END LOOP;
    if DBMS_SQL.IS_OPEN(l_cursor) then
        DBMS_SQL.CLOSE_CURSOR(l_cursor);
    end if;
END;
