Oracle Fleet Patching and Provisioning Communication Ports

Configure communication ports for Oracle Fleet Patching and Provisioning (Oracle FPP) Server, clients, and rhpclient-less targets.

The Oracle Fleet Patching and Provisioning Server communicates with Oracle Fleet Patching and Provisioning Clients and rhpclient-less targets using the following ports, several of which you can configure, as described in the below tables. Additionally, differences in ports used when communicating with Oracle Fleet Patching and Provisioning Clients versus rhpclient-less targets are noted.

Table 2-2 Ports Open on Oracle FPP Server to Communicate with Oracle FPP Client

Protocol	Port	Modifiable	Purpose	Description
UDP	53	No	GNS	The Oracle FPP clients use GNS to locate the Oracle FPP Server.
TCP	8896	Yes. Use the `srvctl modify rhpserver -port port_number` command to modify this port. It requires a restart.	JMX Server	The Oracle FPP Server uses this port to communicate with the Oracle FPP clients.
TCP	Ephemeral range or a custom port	Yes. Use the `srvctl modify rhpserver -pl_port port_number` or `srvctl modify rhpserver -clport port_number` command to modify this port.	Command Progress Listener	The Oracle FPP Server opens a random port from an ephemeral range to monitor progress on the client or `rhpclient`-less target. The Oracle FPP Server can also use a fixed port you specify using `srvctl modify rhpserver -pl_port port_number`, `srvctl modify rhpserver -clport port_number`, and multiplex the fixed port across clients or `rhpclient`-less targets.

Table 2-3 Ports Open on Oracle FPP Client to Communicate with Oracle FPP Server

Protocol	Port	Modifiable	Purpose	Description
TCP	22	Yes	SSH	The Oracle FPP Client requires an SSH port open during initial deployment of Oracle Grid Infrastructure. After you add the cluster as an Oracle FPP Client, Oracle FPP uses the JMX port for communication between Oracle FPP Client and Oracle FPP Server. The default JMX port is 8896. Note: Use the following command to change the SSH port:`./crsctl modify res ora.rhpserver -attr "USR_ORA_ENV='SSH_PORT=new_port'" -unsupported`
TCP	8896	Yes. Use the `srvctl modify rhpclient -port port_number` command to modify this port. It requires a restart.	JMX Server	The Oracle FPP Client uses this port to communicate with the Oracle FPP Server.
TCP	Ephemeral range or a custom range	Yes. Use the `srvctl modify rhpserver -port_range port_number_range` command to modify this port.	Image Transfer	The Oracle FPP Server uses six ports chosen from an ephemeral range, or six ports from the range you define to transfer gold images to the Oracle FPP clients.

Table 2-4 Ports Open on Oracle FPP Server to Communicate with rhpclient-Less Targets

Protocol	Port	Modifiable	Purpose	Description
TCP	Ephemeral range or a custom range	Yes. Use the `srvctl modify rhpserver -pl_port port_number` or `srvctl modify rhpserver -clport port_number` command to modify this port.	Command Progress Listener	The Oracle FPP Server opens a random port from an ephemeral range to monitor progress on the client or `rhpclient`-less target. The Oracle FPP Server can also use a fixed port you specify using `srvctl modify rhpserver -pl_port port_number`, `srvctl modify rhpserver -clport port_number`, and multiplex the fixed port across clients or `rhpclient`-less targets.

Table 2-5 Ports Open on rhpclient-Less Targets to Communicate with Oracle FPP Server

Protocol	Port	Modifiable	Purpose	Description
TCP	22	Yes	SSH	The Oracle FPP Client requires an SSH port open during initial deployment of Oracle Grid Infrastructure. After you add the cluster as an Oracle FPP Client, Oracle FPP uses the JMX port for communication between Oracle FPP Client and Oracle FPP Server. The default JMX port is 8896. Note: Use the following command to change the SSH port:`./crsctl modify res ora.rhpserver -attr "USR_ORA_ENV='SSH_PORT=new_port'" -unsupported`
TCP	Ephemeral range or a custom range	Yes. Use the `srvctl modify rhpserver -port_range port_number_range` command to modify this port.	Image Transfer	The Oracle FPP Server uses a range of six ports, from an ephemeral range or six ports from the range you define, to transfer gold images to the Oracle FPP clients.

Table 2-6 Ports Open on Main Oracle FPP Server to Communicate with Peer Servers

Protocol	Port	Modifiable	Purpose	Description
UDP	53	No	GNS	The Oracle FPP clients and peer servers use GNS to locate the main Oracle FPP Server.
TCP	8896	Yes. Use the `srvctl modify rhpserver -port port_number` command to modify this port. It requires a restart.	JMX Server	The Oracle FPP Server uses this port to communicate with the Oracle FPP clients and peer servers.
TCP	Ephemeral range or a custom range	Yes. Use the `srvctl modify rhpserver -port_range port_number_range` command to modify this port.	Image Transfer	The Oracle FPP Server uses a range of six ports, from an ephemeral range or six ports from the range you define, to transfer gold images to the Oracle FPP clients.
