How to run wrap utility

Question

Hi All,
I tried to use wrap utility from my command promt from c:/oracle9i/bin to encrypt the package code. But found that I am not having any wrap coomand in bin dir, so when I run wrap command from c:/oracle9i/bin, it gave me below error:
C:\oracle9i\bin>wrap
'wrap' is not recognized as an internal or external command,
operable program or batch file.
Can anybody help me in running wrap command. I am not able to understand if this is version issue, or complete pacakage has not been installed on my machine.
Or there is some other way to run wrap utility, and I am running it in wrong manner.
Thanks and Regards,
Nidhi

The wrap utility is a command line utility that obfuscates the contents of a PL/SQL source file. The syntax for the wrap utility is shown below.
wrap iname=input_file [oname=output_file]
The iname parameter specifies the source file, while the oname parameter specifies the destination file. If the destination file is not specified it defaults to the source file name with a ".pld" extension.
Running the Wrap Utility
Wrapping a package is amazingly simple, although there is one pitfall to avoid. Among the 500 plus files in the ORACLE_HOME/bin directory you will see wrap or WRAP depending on your operating system (a lot of the more common files and directories on Windows are upper-cased for ease of readability and identification).
Using wrap is as simple as this:
c:\ora9i\bin wrap iname=input_file_name
You can specify an output file as a second argument by using this format:
c:\ora9i\bin wrap iname=input_file_name oname=output_file_name
Once wrapped, a package cannot be unwrapped. With that in mind, and just like what you would do with a real package, do not wrap the package until it is time to ship it. This implies keeping a source code repository of the original code. If a customer or user reports a bug against a wrapped package, there is no unwrapping it at the customer's site. You are going to have to ship another wrapped package with the fix in it. You will be making the bug fix or enhancement with the repository file and wrapping the new file.
An Example of Using Wrap
In a previous article, I used the DBMS_RANDOM package. A slightly modified bit of code from that produces the following:
SQL> CREATE or REPLACE PROCEDURE wrap_it (seed_in NUMBER)
  2  IS
  3    v_rand INTEGER;
  4  BEGIN
  5    DBMS_RANDOM.INITIALIZE (seed_in);
  6    FOR i IN 1..5 LOOP
  7     v_rand := mod(abs(DBMS_RANDOM.RANDOM),45);
  8     dbms_output.put_line(i||': '||v_rand);
  9    END LOOP;
10  END;
11  /
Procedure created.
SQL> exec wrap_it(123456);
1: 37
2: 36
3: 18
4: 8
5: 32
PL/SQL procedure successfully completed.HTH.
