Skills acquired during recommended training

Architecture

  • Illustrate the relationships between IBM WebSphere Application Server, Network Deployment, V7.0 and the application components (e.g., browser, HTTP server, proxy server, plug-in, firewall, database servers, WebSphere MQ, load balancing, ip spraying, and Tivoli Performance Viewer.)
  • Apply design considerations of IBM WebSphere Application Server, V7.0 when installing an enterprise environment (e.g., LDAP, database servers, WebSphere messaging, etc.)
  • Relate the various components of the IBM WebSphere Application Server Network Deployment V7.0 runtime architecture.
  • Illustrate workload management and failover strategies using IBM WebSphere Application Server Network Deployment V7.0.
  • Describe WebSphere dynamic caching features.
  • Compare the Network Deployment (ND) cell model with the flexible management model.

Installation/Configuration of WebSphere Application Server

  • Identify installation options and determine the desired configuration (e.g., silent install, etc.)
  • Install WebSphere Application Server Network Deployment V7.0 and verify the installation (e.g., Installation Verification Tool (IVT), default application (i.e., snoop and/or hitcount.))
  • Create profiles.
  • Troubleshoot the installation (e.g., identify and analyze log files.)
  • Utilize installation factory and Centralized Installation Manager (CIM).

Application Assembly/Deployment and Cell Configuration/Resource Allocation

  • Describe the name service management of WebSphere Application Server Network Deployment V7.0 (JNDI).
  • Package Java enterprise applications, including enhanced ear files using the Rational Assembly and Deployment Tool.
  • Define and map security roles (e.g., Java enterprise security).
  • Configure application resources (e.g., JCA resource adapters, connection factories, resource scoping, MDB activation specification, JDBC providers, data sources)
  • Configure WebSphere messaging (e.g., SIBus bus members and destinations).
  • Automate deployment tasks with scripting.
  • Manage the plug-in configuration file (e.g., regenerate, edit, propagate, etc.).
  • Configure class loader parameters.

WebSphere Application Server Security

  • Implement security policies (e.g., authentication and authorization (using different security registries), global security, etc.) $Protect WebSphere Application Server Network Deployment V7.0 resources (e.g., Java 2 security, Java EE security roles).
  • Configure SIBus security.
  • Define and implement administrative security roles.
  • Configure SSL clients and servers.
  • Implement federated repositories.
  • Configure WebSphere Application Server Network Deployment V7.0 with multiple security domains.
  • Configure auditing.

Workload Management, Scalability, High Availability Failover

  • Federate nodes (including custom profiles).
  • Create clusters and cluster members.
  • Configure session management (memory-to-memory, database persistence).
  • Create and configure Data Replication Service (DRS) replication domains.
  • Manage Web servers in a managed and unmanaged node.
  • Manage WebSphere messaging in a clustered environment.
  • Configure workload management via the web server plug-in

Maintenance, Performance Monitoring and Tuning

  • Manage application configurations (e.g., application bindings, HTTP session tuning, etc.).
  • Perform WebSphere Application Server Network Deployment V7.0 backup, restore and configuration tasks.
  • Tune performance of WebSphere Application Server Network Deployment V7.0 (e.g., JDBC data source, configure caching, queuing and thread pooling parameters, tune JVM heap size, etc.).
  • Use Tivoli Performance Viewer (TPV) / Request Metrics to gather information about resources and analyze results.
  • Develop and implement a maintenance application strategy using Update Installer and/or Centralized Installation Manager (CIM) (e.g., FixPacks, cumulative fixes and interim fixes.)

Problem Determination

  • Configure, review and analyze logs (e.g., Web server, IBM WebSphere Application Server Network Deployment V7.0, first failure data capture (FFDC)).
  • Use trace facility (e.g., enabling, selecting components, and log configuration).
  • Analyze the content of the JNDI namespace using dumpNameSpace.
  • Perform JVM troubleshooting tasks (e.g., thread dump, JVM core dump, and heap dump, verbose Garbage Collection (GC) ).
  • Have insight to IBM Support Assistant.
