    String URL="jdbc:oracle:thin@charie";
    String user ="MCH1";
    String password ="MCH1";

Enter the password for your 'SYSTEM' ORACLE schema:
...Unable to connect.
AutoPatch error:
The following ORACLE error:
ORA-01017: invalid username/password; logon denied

CONNECT SYSTEM/*****
AutoPatch error:
Unable to connect to 'SYSTEM'; password may be invalid.
