endpoints_listener.ora
A client of mine has Oracle RAC 11.2.0.4 on MS Windows 2008. The endpoints_listener.ora file was modified manually and a mistake was made. The person who modified the file has put in VIP twice, instead of the VIP and the public IP address. I modified it back to the correct public address and restarted the listener using
srvctl stop scan_listener -i 1, followed by srvctl start scan_listener -i 1. Both commands were successful, but the scan listener is still not listening on the public IP address, which can be verified by "lsnrctl status".
