Distributed Server Manager

Manage distributed clustered architecture

Java class: com.orientechnologies.orient.server.handler.distributed.ODistributedServerManager

Introduction

Configure a distributed clustered architecture. This task is configured as a Server handler. The task can be configured in easy way by changing parameters:

• enabled: Enabled the plugin: true to enable, false to disable it
• name: Cluster name. Default value is "default". Multiple clusters can coexist in the same network but using different names
• security.algorithm: Name of the algorithm used to encrypt data sent over the network. Default is "Blowfish"
• network.multicast.address: Multicast IP address. Default is "235.1.1.1"
• network.multicast.port: Multicast IP port. Default is "2424"
• network.multicast.heartbeat: Time in seconds between the sending of multicast heartbeat message to check if server nodes are alive. Default is "10" seconds.
• server.update.delay: Delay time in ms the server is updated in asynchronous way. Default is "5000" ms
• server.electedForLeadership: Tells if the current Server node is eligible for Leadership. Default is "true"
• security.key: Security key used to encrypt data sent over the network. It's auto generated by default the first time the server starts

Default configuration in orientdb-server-config.xml
