컴포넌트	설명	기본 포트 번호	포트 범위	프로토콜	Used Only On Interconnect
Cluster Manager	The port number is assigned automatically during installation. You cannot view or modify it afterward.	Dynamic	Dynamic	UDP	Yes
Cluster Synchronization Service daemon (CSSD)	The Cluster Synchronization Service (CSS) daemon uses a fixed port for node restart advisory messages. This port is used on all interfaces that have broadcast capability. Broadcast occurs only when a node eviction restart is imminent.	42424	Dynamic	UDP	Yes
Grid Plug and Play (GPNPD)	GPNPD provides access to the Grid Plug and Play profile, and coordinates updates to the profile among the nodes of the cluster to ensure that all of the nodes have the most recent profile.	Dynamic	Dynamic	TCP	No
Multicast Domain Name Service (mDNS)	The mDNS process is a background process on Linux and UNIX, and a service on Window, and is necessary for Grid Plug and Play and GNS.	5353	Dynamic	UDP/TCP	No
Oracle Cluster Registry	The port number is assigned automatically during installation. You cannot view or modify it afterward.	Dynamic	Dynamic	UDP	Yes
Oracle Clusterware Daemon (CRSD)	Oracle Clusterware daemon internode connection. The port number is assigned automatically during installation. You cannot view or modify it afterward.	Dynamic	Dynamic	UDP	Yes
Oracle Connection Manager	Listening port for Oracle client connections to Oracle Connection Manager. You can configure Oracle Connection Manager after installation using NETCA.	1630	1630	TCP	No
Quality of Management Service (QOMS) Server	The CRS Agent uses port 8888 locally to manage the lifecycle of the container.	8888	8888	TCP	Not applicable
Quality of Management Service (QOMS) Server	Port for the Quality of Management Service server.	8895	8895	RMI	No

Oracle Fleet Patching and Provisioning Server	Port for the Oracle Fleet Patching and Provisioning server.	8896	8896	RMI	No
Oracle Data Guard	Shares the Oracle Net Listener port and is configured during installation. To reconfigure this port, use Oracle Net Configuration Assistant (NETCA) to reconfigure the listener.	1521 (same value as the listener)	modifiable manually to any available port	TCP	No
Oracle Event Manager (EVM)	Generates events for Oracle Clusterware. The port number is assigned automatically during installation. You cannot view or modify it afterward.	Dynamic	Dynamic	UDP	Yes
Oracle Grid Interprocess Communication (GIPCD)	A support daemon that enables Redundant Interconnect Usage.	42424	Dynamic	UDP	Yes
Oracle Grid Naming Service (GNSD)	The Oracle Grid Naming Service daemon performs name resolution for the cluster.	53	53	UDP	No
Oracle Grid Naming Service (GNSD)	The Oracle Grid Naming Service daemon performs name resolution for the cluster.	Dynamic	Dynamic	TCP	No
Oracle HA Services daemon (OHASD)	The Oracle High Availability Services (OHAS) daemon starts the Oracle Clusterware stack.	42424	Dynamic	UDP	Yes
Oracle Net Listener	Allows Oracle client connections to the database by using Oracle Net Services. You can configure this port during installation. To reconfigure this port, use NETCA.	1521	Port number changes to the next available port. Modifiable manually to any available port.	TCP	No
Oracle Notification Services (ONS)	Port for ONS, used to publish and subscribe service for communicating information about Fast Application Notification (FAN) events. The FAN notification process uses system events that Oracle Database publishes when cluster servers become unreachable or if network interfaces fail. Use srvctl to modify ONS ports.	6100 (local) 6200 (remote)	Configured manually	TCP	No
Oracle Real Application Clusters	The port number is assigned automatically during installation. You cannot view or modify it afterward.	Dynamic	Dynamic	UDP	Yes
Oracle XML DB (FTP)	The Oracle XML DB FTP port is used when applications need to access an Oracle database from an FTP listener.
