When receiving error: "U0038076 File '../db/oracle/9.00A/uc_ddl_SP2.sql' not found." while loading UC_UPD.TXT, r-w-x (777) privilege is required for all files stored in the DB directory.
Solution
a) change access right to r-w-x / 777. b) check path variables for upper and lowercase (INI / Filesystem) c) check input path, "input=" and set a full qualified path to the DB directory.
