3 Modify the properties for the RMI service ports that you want to change.
4 Save your changes and close the msgserver.properties file.
What to do next
Open the new RMI service port or ports on the vRealize Operations Manager firewall. See “Update the
vRealize Operations Manager Firewall,” on page 9.
Update the vRealize Operations Manager Firewall
If you change the default port for an RMI service, you must open the new port on the
vRealize Operations Manager firewall.
NOTE If the Horizon adapter is running on a remote collector, see the documentation for the firewall on the
remote collector node for information about updating the firewall.
Procedure
1 On the cluster node where the Horizon adapter is running, use a text editor to open the vmware-vcops-
firewall.conf file.
The vmware-vcops-firewall.conf file is in the /opt/vmware/etc/ directory.
2 Update the appropriate ports in the vmware-vcops-firewall.conf file and save the file.
3 Restart the firewall service to make your changes take effect.
service vcopsfirewall restart
RMI Considerations for Remote Collector Use
vRealize Operations Manager can use remote collectors to improve performance and scalability in
environments that have multiple data centers. A remote collector can be installed on Windows or Linux and
can host one or more adapter instances. This configuration enables data collection to be distributed across
multiple datacenters.
The use of remote collectors has several serious security implications.
n
To connect the remote collector to vRealize Operations Manager, you must publically expose the RMI
interface of vRealize Operations Manager. No authentication is performed on connections to this
interface. An attacker can use this interface to retrieve arbitrary data, send rogue data, and potentially
take control of vRealize Operations Manager.
n
The connection between the remote collector and vRealize Operations Manager is not encrypted. An
attacker can sniff the network and gain access to data sent from a View adapter instance to
vRealize Operations Manager.
