The replication has been in eXo JCR since 1.6.
The replication feature can be enabled at repository level in the repository configuration :
The parameters are :
A sample configuration of JGroups for 8 participants of the cluster:
<repository name="repository" system-workspace="production" default-workspace="production"> <security-domain>exo-domain</security-domain> <access-control>optional</access-control> <replication enabled="true" mode="persistent" bind-ip-address="192.168.0.15" channel-config="TCP_NIO(use_send_queues=false; ........."> </replication>
| Parameter | Description | values |
|---|---|---|
| enabled | enable/disable replication | true or false |
| mode | type of replication | persistent or proxy |
| bind-ip-address | IP address of the local network interface to use for replication | IP address |
| channel-config | JGroups configuration | See the JGroups Docs |
