Node Agent V5.1 Application Server V5.1 Application Server V5.1 Node V5.1 Figure 3-18 Mixed node versions in a Network Deployment cell 3.2.4 Flexible management Deployment Manager V7.0 Node Agent V6 Application Server V6 Application Server V6 Application Server V7.0 Node V6 Node V7.0 Flexible management is a concept introduced with WebSphere Application Server V7.0. With flexible management components like the administrative agent and the job manager, you can build advanced and large-scale topologies and manage single and multiple application server environments from a single point of control. This reduces management and maintenance complexity. Multiple base profiles The administrative agent component of WebSphere Application Server provides administration services and functions to manage multiple stand-alone (Express and Base) application servers that are all installed in the same system. Figure 3-8 on page 63 shows the administrative agent management model introduced with WebSphere Application Server V7.0. It is possible to manage multiple administrative agents with a job manager. These administrative agents can reside on one or multiple systems. 78 WebSphere Application Server V7.0: Concepts, Planning, and Design Node Agent V7.0 Application Server V7.0 Cell Multiple release levels: You can upgrade a portion of the nodes in a cell, while leaving others at a previous release level. Also, you might be managing servers that are running multiple release levels in the same cell. It is recommended to use this feature only for migration scenarios.
Admin scripts Admin console Admin scripts Integrated Solutions Console Job manager management model and advanced topologies The job manager component of WebSphere Application Server Network Deployment allows you to build advanced management models and topologies for your environment. The job manager can manage multiple administrative agents in different systems and can be the single point of control for these stand-alone server profiles (Figure 3-19). Job Manager Administrative Agent Configurations WebSphere Application Server ND V7.0 Node A Configurations Administrative Agent Application Server WebSphere Application Server V7.0 Node C Configurations Admin scripts Figure 3-19 Job manager management model for multiple administrative agents Application Server WebSphere Application Server – Express V7.0 Node B Integrated Solutions Console In a deployment manager environment, there is a tight coupling between application servers and node agents and also between node agents and the deployment manager. This tight coupling can impact the scalability of the administrative run time if the runtime components are not located together in close proximity using redundant, high capacity, low latency networks.
