ProC Batch Connect To Database Without Password Files

Question

Post Admin
This post relates to ProC. I cannot locate ProC forum, this looks closest. If not please advise.
Question
We have batch ProC program that runs overnight on unix OS. Presently connects to database using userid/password read from file. Security are not happy with existence of file containing userid/password. I am looking for alternatives.
An approach used for sqlplus scripts and export/import is to connect as / as sysdba. This means must be run by OS user who has sysdba power. Are there any other options so ProC can connect without user/password in program or file that is read when run? PS - We do not have time at present to port to plsql inside database and schedule from database for this job.
The equivalent in ProC appears to be
strcpy(uid_pwd.arr,"/ IN SYSDBA MODE");
uid_pwd.len=strlen(uid_pwd.arr);
EXEC SQL CONNECT :uid_pwd;
But I receive
ORA-01017: invalid username/password; logon denied.
Is my syntax okay?
Update
The syntax should be
strcpy(uid_pwd.arr,"/");
uid_pwd.len = strlen(uid_pwd.arr);
EXEC SQL CONNECT :uid_pwd IN SYSDBA MODE;
Apologies for inconvience

The total project is migration database. The application system is Microsoft Dynamic AX system.
We migrate the database from 32 bit system to 64 bit system and the method I used is expdp/impdp
I confirm all the related user have created in new database with same password as the original one.
But now we got one problem. When AX system start, it pop out the error message. In the event view the error is ORACLE error message "invalid username / password" the username is empty.
I have checked with Microsoft engineer for the problem. He give me the suggestion is to use the windows authentication method without using username and password.
So I want to know how to login database from client without username and password.log into DB as which DB user?
