Resolution

There are two solutions.

If you do not require clustering support you can disable the default clustering implementation:

1. Shutdown the server.
2. Set the System Property com.redwood.scheduler.boot.cluster.type=Standalone.
3. Start up the server.
4. Create a new Registry Entry as the administrator - /configuration/boot/cluster/type with a value of Standalone.
5. Shutdown the server.
6. Remove the System Property com.redwood.scheduler.boot.cluster.type=Standalone.
7. Start the server.

If you require clustering support:

1. Shutdown the server.
2. Set the System Property com.redwood.scheduler.boot.cluster.type=Standalone.
3. Start up the server.
4. Create a new Registry Entry as the administrator - /configuration/boot/cluster/<hostname>/<instance number>/<node number>/port with the value being the available port number.
5. Where.
6. hostname - is the name of the host - this will be the same as the host defined in your license.
7. instance number - is the instance number of the node. This will be 0 for Redwood Platform, unless overwritten by the System property com.redwood.scheduler.cluster.rwm.InstanceId.
8. node number - is the number of the cluster node on this server. By default this is mapped from the installation directory, correlating to the number at the end of the directory j2ee/cluster/server<N>.
9. For example the default path will be /configuration/boot/cluster/tomcathost/0/1/port.
10. Shutdown the server.
11. Remove the System Property com.redwood.scheduler.boot.cluster.type=Standalone.
12. Start the server - note the restart can take up to three minutes to start if the shutdown is not completed cleanly. This is due to the failover mechanisms in place.
