Based on my own research, google results and ansible's answer, I was able to come up with complete solution for Oracle Linux 7. Everytime you read Kitet - this is my Oracle Instance SID.
To start or stop database, dbstart and dbshut scripts are used respectively. They are located in $ORACLE_HOME/bin. Both of them need a parameter, which is $ORACLE_HOME. If there's no $ORACLE_HOME environment variable, first there's a need to set it (and some more) by running
. /usr/local/bin/oraenv
(note the preceding period, and it's not $ORACLE_HOME/bin/oraenv). Oraenv script will ask for a SID, which is needed to set correct $ORACLE_BASE. With this, using simply
dbstart $ORACLE_HOME
or
dbshut $ORACLE_HOME
will start and stop the listener and database.
To start listener using lsnrctl or start SQL*Plus using sqlplus / as sysdba, running . oraenv beforehand is also required, unless user wants to set manually some environment variables. If our linux box has only one instance, there's a possibility of automating running of . oraenv by editing user's bash profile. Enter
nano ~/.bash_profile
and type following lines (there's probably already umask 022 entry in this file, as per Oracle Database Installation Guide 12c Release 1 for Linux E41491-10):
export ORACLE_SID=Kitet
export ORAENV_ASK=NO
. /usr/local/bin/oraenv
export NLS_LANG=POLISH_POLAND.AL32UTF8
unicode_start
Line one and three are self explanatory. Line two will make oraenv not ask for database SID and use exported variable. Line four is optional and will set your language preference for client connections (e.g. SQL*Plus or lsnrctl will speak in your native language, if available). Line five is needed for console to display accented characters, and is also optional.
Automating startup and shutdown of Listener and Database
1) Once the instance is created, edit the /etc/oratab file setting the restart flag for each instance to 'Y'. My line is as follows:
Kitet:/home/oracle/app/oracle/product/12.1.0/dbhome_1:Y
2) Next, create a file called /etc/init.d/dbora as the root user, containing the following:
#!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
# path to oracle home (needed only to check if dbstart exists)
ORA_HOME=/home/oracle/app/oracle/product/12.1.0/dbhome_1
# this is the user who installed oracle
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle database and listener:
# Remove "&" if you don't want startup as a background process.
export ORACLE_SID=Kitet
export ORAENV_ASK=NO
. /usr/local/bin/oraenv
# at this point we have $ORACLE_HOME env variable set
su $ORA_OWNER -c "dbstart $ORACLE_HOME" &
touch /var/lock/subsys/dbora
;;
'stop')
# Stop the Oracle database and listener:
export ORACLE_SID=Kitet
export ORAENV_ASK=NO
. /usr/local/bin/oraenv
su $ORA_OWNER -c "dbshut $ORACLE_HOME"
rm -f /var/lock/subsys/dbora
;;
esac
3) Use the chmod command to set the privileges to 750:
chmod 750 /etc/init.d/dbora
4) Associate the dbora service with the appropriate run levels and set it to auto-start using the following command:
chkconfig --add dbora
That's all. dbstart and dbshut should write to their respective logs at $ORACLE_HOME/startup.log and $ORACLE_HOME/shutdown.log. There also is $ORACLE_HOME/listener.log. There we can verify if and how instance and listener started and stopped. We could also use ps -ax | grep ora or ps -ax | grep lsnr to see if listener / oracle are running.

Table
personis situated in schema assigned to your apex workspace. You can go to APEX IDE to the sectionSQL Workshop->Object Browser, schema name will be displayed in the top right part of the page. Or you can execute query:You will get names of all users that have table with such name. After that you need to use this name in your query:
