Available in all packages. Distributed server environment Multiple processes managed from a single deployment manager Only available with Network Deployment Managed processes Deployment manager Node agents Application servers Web servers,System Administration,6,Stand-alone Server : System Administration,System Administration,7,Administrative Clients,Network Deployment: System Administration,ND allows you to manage the entire cell (all processes) from a central Deployment Manager Administrative clients connect to Deployment Manager Changes made by the administrative clients are saved in the master configuration The configuration is then synchronized with the Nodes,Master Configuration for the Entire Cell,V6 Deployment Manager,WEB Container,Embedded HTTP Server,Administrative Services,Administrative Console Application,9060,Internet or Intranet,Soap/HTTP or RMI-IIOP,Custom Java Administrative Clients,Scripting Client (wsadmin),Web Browser,System Administration,8,Node Group: Concept,Logical boundary for separating out servers in a cell Defines boundary for Server cluster Enables mixing nodes with different capabilities within the same cell z/OS NodeGroup and Distributed NodeGroup WBI nodes and Base Nodes Useful for partitioning a cell for licensing purposes. Eg. Only 3 nodes in CellA will connect to a licensed resource like MQ. Define MQ NodeGroup Default node group contains all the nodes,System Administration,9,Node Group Administration,A node must be a member of one or more Node Groups Functions Create New Node Group Delete Node Group It must not have any nodes in its membership Add nodes to the Node Groups Remove nodes from Node Groups,System Administration,10,Topology Example,System Administration,11,Agenda,System Administration Overview System Administration Tools Integrated Web Server Administration Summary,System Administration,12,System Administration Tools,WebSphere administrative console Browser-based interface Command-line operation tools Available in the bin directory wsadmin scripting Interactive and batch modes Ant Java based build and automation tool Java-based JMX APIs Programming interface for custom Java applications,System Administration,13,A Tour of the Administrative Console,System Administration,14,Administrative Console Welcome,Banner,Navigation Tree,Work Area,System Administration,15,Administrative Console Cell Topology,System Administration,16,Administrative Console Guided Activities,System Administration,17,Administrative Console Guided Activities,System Administration,18,Command line tools,WebSphere Application Server V6 supplies command line tools that perform various administrative tasks Start/stop servers, addNode, backupConfig, etc. Most of the commands are in the product install or the profiles “bin” directory Commands run from the /bin directory apply to the default profile, when no profile option is specified Commands run from the /bin directory apply only to that specific profile no need to provide the profile option here - RECOMMENDED,System Administration,19,Command Line Scripting Tool: wsadmin,wsadmin is a non-graphical command interpreter environment enabling you to run administrative operations on a server in a scripting language Introduced in V5 and based on Bean Scripting Framework (BSF) Robust scripting features and programming model Supports JACL and Jython languages With the Version 6.1 release of WebSphere Application Server, we are announcing the start of the deprecation process for the Jacl syntax associated with wsadmin The Jython syntax for wsadmin is the strategic direction for WebSphere administrative automation Jython administrative functions and tooling for automation WebSphere Automation Tools Administrative Console Command Assist IBM Jacl to Jython Conversion Assistant,System Administration,20,wsadmin Command Assistance in Console,Command assist feature in the Administrative Console displays the corresponding wsadmin commands for the last action run in the console Pop-up window shows the wsadmin scripting command in Jython language Preferences include logging the scripts and sending JMX notifications Notifications can be sent to the new Jython editor in the Application Server Toolkit for easy integration into scripts Not all console actions supported by command assistance,System Administration,21,Using Ant To Automate Tasks,Apache Ant is a Java-based build tool Ant has become a very popular tool among Java programmers WebSphere Application Server V6 provides a copy of the Ant tool and a set of Ant tasks that extend the capabilities of Ant to include product-specific functions. Install and uninstall applications Start and stop servers in a base configuration Run administrative scripts or commands Run the EJB deployment tool Run the JSP pre-compilation tool ws_ant is WebSpheres customized ant interface Extended using Java classes Uses XML configuration files,System Administration,22,Configuration Archives,A complete set or subset of WebSphere configuration archive The configuration information is virtualized to make it portable removes any install specific information, like the host name Used to import/export configurations into or from WebSphere Allows declarative way to modify WebSphere configurations,System Administration,23,Agenda,System Administration Overview System Administration Tools Integrated Web Server Administration Summary,System Administration,24,Integrated Web Server Administration,Integrated Web Server administration in V6 Create, Delete, Start and Stop web servers from the admin console Generate unique plug-in configuration files for individual web servers,System Administration,25,Agenda,System Administration Overview System Administ
