Instance "orcl", status UNKNOWN, has 1 handler(s) for this service...,필요한 친구가 있으면 참고하세요.
오늘 서버의 감청 프로그램을 다시 시작했습니다. 다시 시작한 후에 성공했지만 데이터베이스가 사활적으로 등록되지 않아 클라이언트가 데이터베이스에 연결할 수 없습니다.

이 힌트는 일반적으로 매우 정상적으로 여겨지는데, 실례가 감청 서비스에 등록되지 않았기 때문에, 실례를 등록하는 것이다

감청 파일에는 문제가 없는 것 같습니다. 왜냐하면 저는 이전에 문제가 없었기 때문입니다. 앞에서 감청한 로그를 보십시오.
[oracle@localhost admin]$ tail -30 /u01/app/diag/tnslsnr/localhost/listener/alert/log.xml

감청이 시작되었을 때 호스트 이름을 읽었습니다.
localhost.localdomain
, 개인적으로는 호스트 이름 해석에 문제가 있을 것 같아서hosts 파일을 보십시오
[root@localhost oracle]# hostname
localhost.localdomain

[root@localhost oracle]# more /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.3.100 localhost.localdomain

세 개의 IP가 모두 기계 이름인localhost에 대응하는 것을 발견하였다.localdomain, 이 경우 감청이 해석되지 않아 데이터베이스가 감청 프로그램에 등록되지 못할 수 있습니다
[root@localhost oracle]# more /etc/hosts
#127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
172.0.0.1   localhost
192.168.3.100 localhost.localdomain
#::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

그리고 감청 프로그램을 다시 시작합니다.
