# Cluster_Discover

> This sample demonstrates the use of function `mco_cluster_discover()` to determine the list of active nodes.

### How to Run

> To run this sample open three console windows and set the eXtremeDB installation root directory as the current working directory. Then within 5 seconds:

> In one console window run:

>         cluster_demo -n 300000 2 0

> and in a second console window run:

>         cluster_demo -n 300000 2 1

> This starts the cluster for a significant amount of execution time (option “`-n 300000`” forces the two cluster nodes to perform 300,000 transactions each). Then within 10 seconds run:

>         cluster_discover localhost:20000

> Now sample `cluster_discover` will list the two cluster nodes created by `cluster_demo`.

> But it is more instructive to run one instance in your development environment debugger, stepping through the code.
