ORA-12541: TNS:no listener

3788579Oct 26 2018 — edited Dec 29 2018

Hi,

Environment:

VMware Workstation 12 Pro

VM environment:     RHEL 7.3 (3.10.0-514.21.1.el7.x86_64)

                               Oracle 12c (12.2.0.1.0)

Client:     My local pc

I'm trying to connect to the Oracle 12c(12.2.0.1.0) DB via Toad(installed in my local pc) to test the connection to the database but "ORA-12541: TNS:no listener" error prompts. The listener in the VM is present/started, firewall is off, the VM & my local pc can ping each other & the credentials used to login to Toad are correct.

Thanks a lot!
