Configuration
Shared Configuration (Windows)

Introduction

Generally, Mindbreeze supports centralized configuration of services for multiple nodes in one master node. All configuration changes are performed on one master node. All other nodes periodically fetch their configurations directly from master. In some network infrastructures the direct communication between master and nodes is not always guaranteed. In such network infrastructures the services on one node may not to be able to start if the master node is not reachable. The solution to this problem is that each node has its own local master which is always available. The configuration master node persists the configuration on a Windows file share and the local masters synchronizes their configuration from there.

Setup

In order to enable the configuration synchronization over Windows File Share the SharedConfigDirectory Windows Registry Key should be configured in all nodes.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MESMaster\SharedConfigDirectory

The value of this registry key should be the path of the Windows File Share. The node ID of the supposed configuration master should be provided in a file naming masternodeid inside this Windows File Share. All configuration changes performed on configuration master will be persisted in this directory. The local masters synchronize their configurations from this directory.
