DX Unified Infrastructure Management (Nimsoft / UIM)


After configuring multiple UMP nodes per - but changes on one node are not synced to the other.

For example, after adding a new Site or a set of pages on one node, the same Site or pages are not present in the Control Panel on the other node.

A multi-cast test as described in the KB article at fails.

Multicast may not be allowed on your network - check with your network administrator.

It's also possible that Multicast may not be allowed on the traditional 239.x network multicast address.

The UMP requires multicast by default in order to maintain sychronization, so this must be allowed.



If multicast cannot be used, it is possible to use Unicast instead.  Please follow the instructions in this article:


if you find that it is enabled on a different IP range (for example, 224.x), you can make the following changes to the file \wasp\webapps\WEB-INF\classes\, adding the following lines at the bottom of the file:["cluster-link-control"]=["cluster-link-control"]=23311["cluster-link-udp"]=["cluster-link-udp"]=23312["cluster-link-mping"]=["cluster-link-mping"]=23313["hibernate"]=["hibernate"]=23314["multi-vm"]=["multi-vm"]=23315


For "", put the address of your UIM database server.  In the above example port 1433 was used as this reflects the standard port for a Microsoft SQL server, but your environment may differ depending on your database platform.


This does not necessarily have to be the database server, but it has to be the address of a machine that both UMP nodes can freely communicate with, so the database server makes sense.
