Oracle SchemaDiff

I tried to run your utility with following config but not
getting output except following header.

Comparing : TSMARS1.SIEBEL75 vs PRMARS.MARS7

The config file I used was like this.
database_user_1=SIEBEL75
database_user_2=MARS7
database_pwd_1=SIEBEL75
database_pwd_2=MAR71TABLES
database_1=TSMARS1
database_2=PRMARS
map SIEBEL75=MARS7
makescripts=db1
retain_columns=N
parse_sql=Y
ignore_col_pos=Y
tablespace=N
storage=N
output_type=ASCII
output_dir=/opt/ORACLE/home/perl/schema_diff

What am I doing Wrong???
