Listener registration fails.
Hi to all,
we have installed a new OracleDatabase 19c 19.3 SE2 named "CDB2" on a Centos 8.5 and also a listener named "LISTENER_19CSE2" on port 1522.
On the same machine is installed an OracleDatabase 19c 19.14 EE with a database called "TRIBE" and a listener with default name "listener" on port 1521.
The purpose of this is export the 19cEE database "TRIBE", import into new database 19cSE2 "CDB2" and uninstall Oracle19 EE keeping Oracle19c SE2.
Because port 1522 was closed in the firewall, we decided to turn off the old 19cEE listener "listener", and change the port of the new listener "LISTENER_19CSE2" to 1521 :
