SiteMinder's Dynamic HCO functionality allows HCO updates to Dynamic Policy Server Clusters to be picked up dynamically by R12 SP3 and above Web Agents that have the enableDynamicHCO setting set to "Yes" in the SmHost.conf file.
In previous versions of SiteMinder, Web Agents did not automatically discover when Policy Servers were added or removed from a cluster. The Web Agents recognized the changes only after their respective web servers were restarted.
SiteMinder r12.0 SP3 supports dynamic Policy Server clusters. When dynamic Policy Server Clusters are enabled, Web Agents automatically discover any additions or removals of individual Policy Servers from an existing cluster.
Do the R12 SP2 Application Server Agents for WebSphere and WebLogic support the Dynamic Policy Server Cluster functionality?
R12 SP3 and above SiteMinder Policy Server
R12 SP2 Application Server Agent for WebLogic or WebSphere
No the R12 SP2 Application Server Agents for WebLogic and WebSphere do not utilize the Dynamic Policy Server Cluster functionality since these Agents are based on the R12 SP2 code base. Dynamic Policy Server Clusters was not introduced until R12 SP3.
