configure cluster database - pluggable database - FAILED: ORA-20500
hello
I want to promote a cluster database (container with its pluggables) via the auto discovery page.
In the configuration screen I see both instances but one in upper case and with the domain and one in lower case without domain name.
As a result, the pluggables are double in the list, if I don't change anything here I get an error when saving the targets:
ora-20500 target with matching attributes already exists.
Anyone have an idea where these instance names come from ? (v$database and v$instances checked, I can't find it) How can I avoid this ?
Thanks
