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
On Microsoft Windows:
>netstat -an|findstr
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.|

|
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. |
|

|
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 omsemctl config oms -store_repos_details -repos_conndesc emctl start oms emctl config emrep -agent
To modify this port for monitored
targets, change the listener configuration on the target, then update
Monitoring Configuration in EM.
