20.14.7. Configuring the HornetQ Servers for Replication
To configure the live and backup servers to be a replicating pair, configure the
standalone-full-ha.xml files on each server to have the following settings:
<shared-store>false</shared-store>
<backup-group-name>NameOfLiveBackupPair</backup-group-name>
<check-for-live-server>true</check-for-live-server>
.
.
.
<cluster-connections>
<cluster-connection name="my-cluster">
...
</cluster-connection>
</cluster-connections>Table 20.15. HornetQ Replicating Setup Attributes
| Attribute | Description |
|---|---|
| shared-store |
Whether this server is using shared store or not. Default is false.
|
| backup-group-name |
This is the unique name which identifies a live/backup pair that should replicate with each other
|
| check-for-live-server |
If a replicated live server should check the current cluster to see if there is already a live server with the same node id. Default is false.
|
| failover-on-shutdown |
Whether this backup server (if it is a backup server) becomes the live server on a normal server shutdown. Default is false.
|
The backup server must also be flagged explicitly as a backup.
<backup>true</backup>
Table 20.16. HornetQ Backup Server Setup Attributes
| Attribute | Description |
|---|---|
| allow-failback |
Whether this server will automatically shutdown if the original live server comes back up. Default is true.
|
| max-saved-replicated-journal-size |
The maximum number of backup journals to keep after failback occurs. Specifying this attribute is only necessary if allow-failback is true. Default value is 2, which means that after 2 failbacks the backup server must be restarted in order to be able to replicate journal from live server and become backup again.
