HI I am trying to Connect Oracle 18c XE using DOA 4.1.2.0 from Delphi 2009. Unfortunately I am getting ORA-12170 error. Connecting with SQLPLUS is working fine, TNSPING is working fine. Anybody with a godd idea ?
In the mean time i deinstalled the client completely and did a reinstall, but the error still raises. SQLPlus is workig correctly, TNSPING works, but still get the message timeout
