[midPoint] How to Configure Midpoint in Cluster Mode

[Ivan Noris]

Hi Gus,

you have to specify the option via command line parameters for midpoint
process or in config.xml

E.g. -Dmidpoint.nodeId=Node1


in config.xml it seems the <nodeId>Node1</nodeId> must be in <midpoint>
section of the file.

<configuration>
    <midpoint>
    <nodeId>MyNode1</nodeId>
    <taskManager>
       
<clustered>true</clustered>                                                                                                          
 
    </taskManager>

...

It works for my case with midpoint 4.2-support (I have only one node,
but it starts as clustered and I can see the node name in Server tasks -
All nodes)

In case of two nodes, they must have different names of course.

Best regards,

Ivan
