a. Change directories (cd) to the student files directory for this chapter.  Use pwd to find the full path.

   pwd

   For this example, we'll assume this path is /home/student/o10advpl/ch10.

b. Open the directory for read and write access to everyone:

   ls -ld .
   chmod 777 . 

c. For each parent directory, make sure the oracle user will be able to access it.  On many Linux systems, user account
   home directories have permission mode 700.  Change this to 755:

   cd
   ls -ld .
   chmod 755 .

d. In SQL*Plus, create the DIRECTORY object:

   CREATE DIRECTORY xmldocdir AS '/home/student/o10advpl/ch10';
