1. Установим из rpm пакетов:

apt-get install -y libaio1 alien
# Change version based on https://www.oracle.com/de/database/technologies/instant-client/linux-x86-64-downloads.html
# Example alternative: http://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/getPackage/oracle-instantclient19.5-basiclite-19.5.0.0.0-1.x86_64.rpm
wget http://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/getPackage/oracle-instantclient19.6-basic-19.6.0.0.0-1.x86_64.rpm
sudo alien -i --scripts oracle-instantclient*.rpm
rm -f oracle-instantclient*.rpm  

# Optionally install SQLPlus
wget http://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/getPackage/oracle-instantclient19.6-sqlplus-19.6.0.0.0-1.x86_64.rpm
sudo alien -i --scripts oracle-instantclient*.rpm
rm -f oracle-instantclient*.rpm  

2. Создадим файл /usr/lib/oracle/19.6/client64/lib/network/admin.tnsnames.ora

BILLING =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = bill.xxx.local)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SID = billing)
    )
  )

3. Проверим:

sqlplus user@billing

1. dpkg --add-architecture i386

2. apt update

3. apt install libc6-i386
