ORA-12518, TNS:listener could not hand off client connection

User_D1N1ONov 24 2022

Hi, I am first using the Oracle database and the first time that I'm going to connect with the database, I've encountered this problem:
An error was encountered performing the requested operation:

Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
(CONNECTION_ID=oSwOePB1Roa6rvGvbfhqcA==)

Vendor code 12518
May I know what problem is it? And is there any solution on it?
