using exp,SQL DBA need help

Hi,
am not oracle dba and I have to backup oracle 8 db using exp command (exp userid=valid_user/valied_pass full=y )

my questions
1. to run command do have to login directly on server hosting
db or it could be done from station having admin tools?

2. if server hosting more then 1 db ,where in command to specify db name?
3. is it possible to specify location for full backup using exp

Thanks
Alex

1. you can run it from anywhere, but it may be slow on client as file will be written where you run it from.

2. you can set oracle_sid variable or do valid_user/pass@oracle_sid

3. yes, parameter is file=

for other options, run exp -help at command prompt.
