목적 ▣ Host Naming과 Local Naming의 차이점 ▣ Oracle Net Configuration Assistant의 사용 ▣ 간단한 연결 문제 해결 방법 -2 -
Naming Method란? ▣ Oracle Net이 제공하는 Naming Method ◈ Host Naming ◈ Local Naming ◈ Directory Naming ◈ Oracle Names ◈ External Naming -3 -
Network 관련 파일 복사 ▣ 접속 ◈ 203. 252. 164. 200 ◈ dba번호/dba번호 ▣ 생성 테스트 ◈ sqlplus “/ as sysdba” ◈ Select 이용한 검색 ▣ cd network/admin ▣ cp /ocp/network/*. / -4 -
Host Naming : Client Side -6 -
Host Naming : Server Side -7 -
Host Naming 예제 ▣ listener. ora 파일 ◈ SID_LISTENER = ◈ (SID_LIST = ◈ (SID_DESC = ◈ (GLOBAL_DBNAME = ORCL. konkuk. ac. kr) ◈ (ORACLE_HOME = C: oracleora 92) ◈ (SID_NAME = ORCL) ◈ ) ▣ 클라이언트 ◈ sqlplus scott/tiger@ORCL. konkuk. ac. kr ▣ 개인 컴퓨터에서 테스트 할 경우에는 WINDOWSSystem 32driversetchosts 파일을 수정해야 함 -8 -

Oracle Shared Server의 사용 및 설정 김동오 -17 -
목적 ▣ Oracle Shared Server의 구조 ▣ Oracle Shared Server의 설정 ▣ 관련된 Data Dictionary -18 -
서버의 설정 ▣ Dedicated Server Process ▣ Shared Server Process -19 -
Dedicated Server Processes -20 -
Oracle Shared Server -21 -
Request 수행 절차 -25 -
SGA와 PGA ▣ Dedicated Server: User Session 데이터는 PGA에 저장 ▣ Shared Server : User Session 데이터가 SGA에 저장 -26 -
Oracle Shared Server의 구성 ▣ 초기화 파라미터 ◈ DISPATCHERS ◈ SHARED_SERVERS ▣ 부가적인 초기화 파라미터 ◈ MAX_DISPATCHERS ◈ MAX_SHARED_SERVERS ◈ CIRCUITS ◈ SHARED_SERVER_SESSIONS -27 -
MAX_DISPATCHERS ▣ 동시에 실행되는 최대 디스패쳐의 수를 입력 ▣ 초기에 실행된 디스패쳐의 수를 늘이려면 ALTER SYSTEM 명령을 이용 ▣ 최대 디스패쳐의 개수 = CEIL(Maximun number of concurrent sessions/Connections per dispatcher) ▣ V$CIRCUIT, V$DISPATCHER ▣ ALTER SYSTEM SET DISPATCHER=‘(PROTOCOL=TCP)(DISPATCHER=3)’; -29 -
