Create a static cluster of ODRs

Create a static cluster of on demand routers (ODRs). A static cluster is a group of application servers in a WebSphere Application Server Network Deployment environment that participates in workload management.

When an ODR is a member of a cluster, routing rules and other configuration settings that are set at the ODR level are ignored. Configuration settings at the cluster level take precedence over any configuration settings at the server level.

Create a static ODR cluster when we are integrating the SIP ODR with Load Balancer for IBM WAS.

Create a static cluster of HTTP ODRs to administer all ODRs at one time. If we do not create a static cluster, we must administer each ODR individually.

Create a static ODR cluster and add members to it...

./wsadmin.sh -lang jython -f manageODR.py convertToCluster <ODR_node>:<ODR_name><cluster_name>

Create the specified ODR, and add it to the cluster...

./wsadmin.sh -lang jython -f manageODR.py addToCluster <ODR_node>:<ODR_name><cluster_name>

Remove the static ODR cluster and its members:

$AdminTask deleteCluster {-clusterName <cluster_name>}

The SIP ODR is stabilized, and is currently not recommended. Use the SIP proxy server instead.

Tasks

1. Create an ODR to use as a template when we create the cluster.

   We can create the ODR in the administrative console or with the createodr.jacl script.

2. Create a static cluster.
   $AdminTask createCluster {-clusterConfig {-clusterName odr_cluster_name -clusterType ONDEMAND_ROUTER} -convertServer {-serverNode node -serverName my_odr}}

   For the my_odr value, specify the name of the ODR created as a template.

3. Add ODRs to the static cluster. Run the following command for each ODR cluster member:
   $AdminTask createClusterMember {-clusterName odr_cluster_name -memberConfig {-memberNode node -memberName odr_cluster_member_name}}

4. Save changes. Run the following command:
   $AdminConfig save

What to do next

To modify the settings of an ODR static cluster, such as the action type and rule expression, use wsadmin.sh to complete administrative tasks at the cluster level. For more information, read about rules for ODR routing policy administrative tasks and rules for ODR service policy administrative tasks.
