Viewing lock

Question

I want to use CATBLOCK.SQL in PL/SQL to display locking information.
now, I'm in C:\oraclexe\app\oracle\product\10.2.0\server\BIN
but CATBLOCK.SQL and UTLLOCKT.SQL are in
C:\oraclexe\app\oracle\product\10.2.0\server\RDBMS\ADMIN
I use "HO cd" to change dirctory, it doesn't work.
and when I ran the following command, I got these message. How should i do? Thanks a lot.
SQL> @C:\oraclexe\app\oracle\product\10.2.0\server\RDBMS\ADMIN\UTLLOCKT.SQL

You can use @@.
From SQL*Plus documentation:
Examples
Suppose that you have the following script named PRINTRPT:
SELECT DEPARTMENT_ID, CITY FROM EMP_DETAILS_VIEW WHERE SALARY>12000;@EMPRPT.SQL@@ WKRPT.SQL
When you START PRINTRPT and it reaches the @ command, it looks for the script named EMPRPT in the current working directory and runs it. When PRINTRPT reaches the @@ command, it looks for the script named WKRPT in the same path as PRINTRPT and runs it.
Suppose that the same script PRINTRPT was located on a web server and you ran it with START HTTP://machine_name.domain:port/PRINTRPT. When it reaches the @ command, it looks for the script named EMPRPT in the current working directory and runs it. When PRINTRPT reaches the @@ command, it looks for the script named WKRPT in the same url as PRINTRPT, HTTP://machine_name.domain:port/WKRPT.SQL and runs it.
Also, I am pretty sure those table drop errors are normal.
Can you select from DBA_WAITERS?
