After creating the ODR, it is capable of routing work to application servers. More advanced properties can also be set on the ODR to determine how it handles failure scenarios and to tune work requests. <br/><br/> <strong>Tip:</strong> When creating an ODR, select a node to run the ODR that does not run any dynamic clusters. <br/><br/> For more information: <br/> <IMG SRC="../com.ibm.ws.console.guidedactivity/images/topic.gif" border="0" alt="Online task documentation" align="absmiddle"/> <a target="help" href="http://www14.software.ibm.com/webapp/wsbroker/redirect?version=phil&product=was-nd-dist&topic=twve_odoecreateodr">Creating and configuring the ODR</a> <br/> <IMG SRC="../com.ibm.ws.console.guidedactivity/images/command_prompt.gif" border="0" alt="Online task documentation" align="absmiddle"/> <a target="help" href="http://www14.software.ibm.com/webapp/wsbroker/redirect?version=phil&product=was-nd-dist&topic=rwve_odrscript">Creating and deleting on demand routers with scripts</a> A dynamic cluster is a group of servers that function as a deployment target. Only servers that are the same type can be members of the same dynamic cluster. Dynamic cluster membership can be controlled by defining a list of specific servers or by defining membership policies which describe the capabilities each dynamic cluster member must have.
