On occasion you will need to perform some tasks using SQL*Plus and/or the operating system command line. In Practice 2, you will start an SQL*Plus session. Continue to keep the SQL*Plus session open to accomplish those tasks done in SQL*Plus. When performing tasks that require the operating system command line, an [ ! ] will be used from the SQL*Plus command line to get you out of SQL*Plus and into the operating system command line mode. Once you have completed your work on the operating system command line you can return to the SQL*Plus command line.
