Add SQL for Oracle at section USERS and revise ACL

I feel very painful when using SQL script for Oracle database. I set datatype, number(18), number(38) is too big, all character is uppercase (because Oracle database is case-insensitive). ACL's SQL script has script for Oracle database, but section USERS, AUTHORITIES has not SQL scrip for Oracle database, therefore I add more.
