Oracle DB does not start

Sometimes people wonder why Oracle DB (both 10g and 11g) will not start after installation on Linux/Unix. In many cases the simple reason is the content of /etc/oratab. For each database it contains a line in the format $ORACLE_SID:$ORACLE_HOME:START_DB_FLAG:The last column is set to “N” by default. Just change it to “Y” and run $ORACLE_HOME/bin/dbstart again. Your database should come up now.
