Oracle 19.3 - cannot add service because of ora-44303

Hi,

we have got an serious issue with creating additional services to our new 19.3 db (single instance).

Yesterday I created a service named "ORCL", started it and found it working. There was also service "ORCL.domain.com" which comes from default installation but we wanted to have service without "domain.com" suffix so decided to create a new one "ORCL" :)

Today morning we've restarted this DB, and couldn't connect via "ORCL" service. So we started our investigation. And we found:

  1. No rows with "ORCL" name in dba_services table.
  2. Creating Service "ORCL" through DBMS_SERVICE.create_service gives us ora-44303 "service name already exists".

Howdy, Stranger!
