Hi guys,
I have recently started with learning oracle DBA. I am still newbie here.
So i have just some questions which i couldn't find answer on google(actually i got confused).
When i just type sqlplus on terminal
It ask for user name and password. If i give this user name and password then I start an instance and db is not yet up. then give startup command and its mount db,open db.
How does sqlplus come to know which db to startup here, as i didn't gave any db name? is there something like default database?
How i can open up other database from same sqlplus window if they are there.
Also please let me know if i can shutdown a specific db from same sqlplus window.
Can i connect to other db using connect command, if i am already logged into one db. ?
One out of topic question.: DBA use sqlplus command prompt window to mange their task or is there any browser based application that they use to manage with their work.
Many thanks for answering them
