I think it is better to follow the modern ways of APEX installation without all those hassles. The containerization will provide you with the whole needed stack to run APEX in an automated manner.
I hope that helps
but i did not find the way to install apex 18 in your link
also there is no one tell me is my steps in previous for install apex is true or false and why
the display interface to insert xdb user and password even if i insert the xdb user insert it display
again and i can not launch to apex home interface?
