===== 設定 =====

  sudo apt-get install alien

  alien -i oracle-instantclientXX.X-basiclite-XX.X.0.0.0-1.x86_64.rpm
  alien -i oracle-instantclientXX.X-sqlplus-XX.X.0.0.0-1.x86_64.rpm

  sudo ldconfig

  sudo sudo vi /etc/profile.d/oracle.sh && sudo chmod o+r /etc/profile.d/oracle.sh


/etc/profile.d/oracle.sh
  export ORACLE_HOME=/usr/lib/oracle/12.1/client64
  export PATH=$PATH:$ORACLE_HOME/bin
  export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib/${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
  export NLS_LANG=Japanese_Japan.UTF8

ここまでくればSQLPLUSが動くはず。
