    p1 = 1509 is the temporary tablespace data file.

    1509 = (value in db_files parameter in init.ora)+abs.file_number from v$tempfile.

    What is the current value you set for db_files?

    Example:
    show parameter db_files

    NAME TYPE VALUE
    -------------------- ----------- ------------------------------
    db_files integer 900

    grep "direct path write" test_ora_1405102.trc
    WAIT #1: nam='direct path write' ela= 2236 p1=901 p2=98628 p3=10
    WAIT #1: nam='direct path write' ela= 2 p1=901 p2=98638 p3=2
