# Generated by Oracle configuration tools.

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

- NAMES.DIRECTORY_PATH : 오라클 클라이언트가 데이터베이스 접속시 별칭(Alias)의 확인 순서를 결정

  NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

  1. Hostname : 호스트네임서버 

 2. TnsNames : 로컬네임서버(tnsnames.ora)

2. 통신환경 설정: /home/oracle/app/oracle/product/19.3.0.0/dbhome_1/network/admin/listener.ora

- 프로토콜 및 포트 정의

- 리스너 설정

LISTENER       : 리스너 이름 SID_LIST_리스너이름, SID_LIST_리스너이름과 같아야함

ADDRESS_LIST    : ADDRESS들의 모임이며 여러 개의 ADDRESS를 동시에 설정 가능

ADDRESS        : 데이터베이스 서버의 주소와 프로토콜, Host명,포트번호 지정

- SID LIST

SID_LIST_LISTENER : SID_LIST_리스너이름 리스너 서비스 이름 지정

SID_LIST      : 해당 리스너 프로세스가 하나 이상의 데이터베이스를 서비스 할 경우에 해당 부분에 여러개의 SID_DESC를 등록한다.

SID_NAME      : 리스너의 접속을 허용하는 데이터베이스의 SID 명을 지정한다.

- 리스너 상태 확인 : lsnrctl status
