# HA_Mcast

> This sample demonstrates the eXtremeDB High Availability multicast mode. The master application creates and populates the database, then enters a loop creating and deleting objects as it waits for connection requests from replicas. Replica applications create duplicates of the master database, synchronize them with the master database, then receive commit data from the master and perform replication in multicast mode.

> (Note that the eXtremeDB `mcoha` library must be configured with `MCO_CFG_HA_MULTICAST_SUPPORT` in order to run this sample.)

### How to Run

> See instructions here on how to build this and other samples on your development platform. Once built, the sample can be run from the `\target\bin` directory.

> In a console window run:

>         hamcast_master

> Then in a second console window run:

>         hamcast_replica

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