Bug 36326543
On Oracle Linux 9.2, the listener fails to start due to issues with
getaddrinfo()
if the /etc/hosts
has an entry in
the order IPv4 and IPv6 addresses when the same host name and listener are configured
with IPv6 address and ip=v6_only.
Workaround
Change the order of the address in the /etc/hosts
entry
with IPv6 first and then IPv4.
