Network Ports Used in Oracle Enterprise Manager 12c

When planning and configuring your Oracle Enterprise Manager 12c implementation, you will have many infrastructure considerations. One of the most often discussed pieces is the network ports that are used and how to configure load balancers, firewalls and ACLs for communication.

This blog post will help identify the typical default port and range for each component, how to identify it and how to modify the port usage.

To modify most ports during installation, select the Advanced Installation and set the appropriate ports on the Port Configuration Details screen.


Once the system is installed, you can use the following EMCTL or OMSVFY commands to validate components and port assignment:

$emctl status oms -details
$omsvfy show opmn
$omsvfy show ports

To verify if a port is free, run the following command:

On Unix:
$netstat -an | grep <port no>

On Microsoft Windows:
>netstat -an|findstr <port_no>

For more information on OMSVFY (part of the EMDIAG toolkit) see MOS Note 421053.1: EMDIAG Troubleshooting Kits Master Index

External Ports

These ports will be used in every Enterprise Manager 12c installation and will require firewall and/or ACL modifications if your network is restricted.  These are also the components that will be added to your load balancer configuration.

Default Port

Component

Usage

4889

4889 – 4898

Enterprise Manager OHS Upload HTTP

Agent Communication to OMS (unsecure). Used in load balancer.

To modify after install follow notes 1381030.1 and 1385776.1. Requires changes on all Agents.

1159

1159, 4899 – 4908

Enterprise Manager OHS Upload HTTP SSL

Agent Communication to OMS (secure). Used in load balancer.

To modify after install follow notes 1381030.1 and 1385776.1. Requires changes on all Agents.

7788

7788 – 7798

Enterprise Manager OHS Central Console HTTP (Apache/UI)

Web browser connecting to Cloud Control Console (unsecure). Used in load balancer and for EM CLI.

To modify after install follow notes 1381030.1.

7799

7799 - 7809

Enterprise Manager OHS Central Console HTTP SSL (Apache/UI)

Web browser connecting to Cloud Control Console (secure). Used in load balancer and for EM CLI.

To modify after install follow note 1381030.1.

7101

7101 - 7200

EM Domain WebLogic Admin Server HTTP SSL Port

Cloud Control Admin Server.

To modify after install follow note 1109638.1.

3872

3872, 1830 – 1849

Cloud Control Agent

Only the OMS will connect to this port, to either report changes in the monitoring, submit jobs, or to request real-time statistics.

Port can be provided during Agent install.

If the agent port needs to be changed at a later date this can be done with the following command on the agent:
emctl setproperty agent -name EMD_URL -value https://hostname.domain:port/emd/main/

This will allow the agent to run on the new port, however the target does not get renamed so continues to show the original port.

1521*

Depends on Listener Configuration

Database Targets -  SQL*Net Listener

For Repository database, only the OMS will connect to store management data from

the agents. For all monitored target databases OMS will retrieve information requested by browser clients.

To modify this port for the repository database:

Change the listener.ora file for the EM repository. Restart the listener. Then for every OMS machine using that repository run the following:

emctl stop oms
emctl config oms -store_repos_details -repos_conndesc <connect descriptor of database> -repos_user sysman
emctl start oms
emctl config emrep -agent <agent name> -conn_desc <connect descriptor of database> 

To modify this port for monitored targets, change the listener configuration on the target, then update Monitoring Configuration in EM.

7101

7101 - 7200

FMW Targets – Admin Console

Outgoing from OMS, used for managing FMW targets.

To modify after install follow note 1109638.1.

NA

NA

ICMP

Outgoing from OMS to host servers if the Agent is unreachable. Validates if server is up or down.

NA

Internal Ports

These ports are required for internal Enterprise Manager communication and typically do not require additional firewall/ACL configuration.

Oracle Notification Server (OPMN) Local

Ports used by OPMN  can be verified from <MW_HOME> /gc_inst/WebTierIH1

/config /OPMN/opmn/opmn.xml:


<debug comp="" rotation-size="1500000"/>
<notification-server interface="any">
<port local="6700" remote="6701"/>

Modify the opmn.xml to use free ports as below:

1. Stop OMS

2. Take a backup of the existing opmn.xml and ports.prop in the <MW_HOME>/ gc_inst/WebTierIH1/ config /OPMN/opmn directory.

3. Edit the opmn.xml file, under the <notification-server> element, modify the local / remote port, as necessary to the free port available and save the file.

4. Edit the ports.prop file and modify the remote / local port parameters as necessary and save the file.

5. Start the OMS

6200 - 6201

Oracle Notification Server (OPMN) Remote

Ports used by OPMN  can be verified from <MW_HOME> /gc_inst/WebTierIH1

/config/OPMN/opmn/opmn.xml:


<debug comp="" rotation-size="1500000"/>
<notification-server interface="any">
<port local="6700" remote="6701"/>

Modify the opmn.xml to use free ports as below:

1. Stop OMS

2. Take a backup of the existing opmn.xml and ports.prop in the <MW_HOME> /gc_inst/WebTierIH1/ config/OPMN/opmn directory.

3. Edit the opmn.xml file, under the <notification-server> element, modify the local / remote port, as necessary to the free port available and save the file.

4. Edit the ports.prop file and modify the remote / local port parameters as necessary and save the file.
