# Cluster_Binev

> This sample demonstrates using the Binary Schema Evolution feature of eXtremeDB to open different versions of the database `cldb` on different cluster nodes. Note that schema files `schema1.mco`, `schema2.mco` and `schema3.mco` have slightly different field types and the metadictionary functions `mco_metadict_init()` and `mco_metadict_register()` are used to initialize the metadictionary prior to calling `mco_cluster_db_open()`.

### How to Run

> In a console window run:

>         cluster_binev 2 0

> Then in a second console window run:

>         cluster_binev 2 1

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