Oracle Database Discussions

hello,

i want to import a dump file into my database named orcl, and i come accross the same error after executing the import command. my import command is:
*************************
SQL> imp mvdemo/mvdemo file=mvdemo.dmp full=y ignore=y
*************************

i use oracle 10g enterprise edition.
i created the user mvdemo/mvdemo.

the error i see in my screen is:
*************************
SP2-0734: unknown command beginning "imp mvde..." - rest of line ignored.
*************************

for a long period of time, i havent used oracle dbms. before, i remember that i used enterprise manager in import/export processes. however, i am not able to find the enterprise manager in 10g options now. do i have to install the enterprise manager seperately in oracle 10g enterprise edition? may this problem be relational with this matter?

if someone could answer, i would be greatful.

best regards
