oracle12c - How to start Oracle DB and how to connect to it? -

-

i have downloaded latest database app development virtual machine oracle linux 7 , oracle database 12c release 1 enterprise edition (12.1.0.2 in-memory option) , oracle sql developer.

how start database or verify running? how connect it?

i checked , db running. open xterm window , type sqlplus system/oracle , you'll logged db. it's set go. firefox - apex working. sqldeveloper setup connection system, password "oracle".

and, if go applications > system tools > system monitor , click on processes , scroll down you'll see many "ora_" processes - these oracle server background processes running. if connected database, 1 represent forground, connected process.

please note. lab environment meant people learn developing apps on oracle. consider this one more "dba" type learning , more info on startup/shut down.
