WLM using corbaloc URL

--------------------------------

Hi All,

I am using the corbaloc URL in my application as below. I understand that the entire request will go to node1 and only in failover scenario request will be routed to node2.

I would like to understand how workload management can be done here. If I configure weight as 2 for all below nodes, will it able to route the request to all the nodes.

corbaloc node1 port1, node2 port2,node3 port3

Routing is done based off the weight set on the cluster memebers. Take a look at this doc.

WLM Routing
Routing is based on weights associated with cluster
members
Round Robin routing when weights are equal
Weights can be modified to send more requests to a
particular cluster member or members
More Information about WLM routing from the v6.1
Information Center
publib.boulder.ibm.com/infocenter/wasinf...
ultiplatform.doc/info/ae/ae/crun_srvgrp.html
If the client is on the same physical box as the cluster, the
“Prefer Local” setting will ensure that all requests from the
client go to the local cluster member

I agree that routing can be done based on the weights. However, that is only for http request. Here I am passing the iiop port number. So, I would need loadbalancing for iiop instead of http.

Thanks,

The whole presentation is about EJB WLM (check page 3).

Also check the infocenter

publib.boulder.ibm.com/infocenter/wasinf...

Workload management for EJB containers can be performed by configuring the Web container and EJB containers on separate application servers. Multiple application servers can be clustered with the EJB containers, enabling the distribution of enterprise bean requests between EJB containers on different application servers.
In this configuration, EJB client requests are routed to available EJB containers in a round robin fashion based on assigned server weights. The EJB clients can be servlets operating within a Web container, stand-alone Java programs using RMI/IIOP, or other EJBs.
