Test 000-253: IBM WebSphere Application Server Network Deployment V6.1, Core Administration


The test consists of seven sections containing a total of approximately 54 multiple-choice questions. The percentages after each section title reflect the approximate distribution of the total question set across the sections.

Section 1 - Architecture (17%)

  • Discuss the relationships between IBM WebSphere Application Server, V6.1 and the application components (e.g., browser, HTTP server, plug-in, firewall, database servers, WebSphere MQ, load balancing, and ip spraying.)
  • Evaluate the design considerations of IBM WebSphere Application Server, V6.1 packaging and installation in an enterprise environment (e.g., LDAP, database servers, Service Integration Bus Technology (SIB), etc.)
  • Articulate the various components of IBM WebSphere Application Server Network Deployment, V6.1 runtime architecture.
  • Describe workload management and failover strategies using IBM WebSphere Application Server, V6.1.
  • Articulate the usage of Session Initiation Protocol (SIP) in WebSphere.
  • Articulate support for portlet containers.
  • Describe WebSphere dynamic caching features.

Section 2 - Installation/Configuration of Application Server (13%)

  • Identify installation options and determine the desired configuration (e.g., silent install, required/desired plug-ins etc.) 
  • Install WebSphere Application Server and verify the installation (e.g., IVT, verification using sample (snoop and/or hitcount.))
  • Create profiles.
  • Utilize installation factory to create custom install packages.
  • Troubleshoot the installation (e.g., identify and analyze log files.)

Section 3 - Application Assembly and Deployment (17%)

  • Describe the name service management of WebSphere Application Server (JNDI).
  • Package J2EE applications, including Enhanced Ear Files using the Application Server Toolkit (AST).
  • Define and map security roles (e.g., J2EE security). 
  • Define JDBC providers and data sources (e.g., resource scoping). 
  • Configure J2C resource adapters, connection factories (resource scoping) and Message Driven Bean Activation Spec. 
  • Configure WebSphere JMS providers.
  • Automate deployment tasks with scripting.

Section 4 - WebSphere Security (11%)

  • Implement security policies (e.g., authentication and authorization (using different security registries), etc.) 
  • Protect WebSphere resources. 
  • Define and implement WebSphere administrative security roles. 
  • Configure WebSphere plug-in to use SSL.
  • Describe Federated Repositories using Virtual Member Manager (VMM).
  • Implement federated repositories.

Section 5 - Workload Management, Scalability, Failover (11%)

  • Federate nodes (including custom profiles). 
  • Create clusters and cluster members. 
  • Evaluate session state failover options (memory-to-memory, database persistence). 
  • Create and configure Data Replication Service (DRS) replication domains. 
  • Manage Web Servers in a managed and unmanaged node.

Section 6 - Maintenance and Performance Tuning (18%)

  • Manage application configurations (e.g., application bindings, tune HTTP session configuration parameters such as timeout value, persistence, etc.). 
  • Perform WebSphere backup, restore and configuration tasks. 
  • Monitor size of log files and backup/purge as needed. 
  • Manage the plug-in configuration file (e.g., regenerate, edit, propagate, etc.). 
  • Tune performance of WebSphere Application Server (e.g., configure caching, queuing and thread pooling parameters, tune JVM heap size, etc.). 
  • Use Integrated Tivoli Performance Viewer/Runtime Advisor to gather information about resources and analyze results. 
  • Tune data source configuration (e.g., connection pooling, timeouts, etc.). 
  • Configure class loader parameters. 

Section 7 - Problem Determination (13%)

  • Configure, review and analyze logs (e.g., Web server, IBM WebSphere Application Server). 
  • Use Log Analyzer from the Application Server Toolkit to analyze logs. 
  • Use trace facility (e.g., enabling, selecting components, and log configuration). 
  • Use First Failure Data Capture (FFDC) Tool. 
  • Use the JNDI dumpNameSpace utility. 
  • Perform JVM troubleshooting tasks (e.g., thread dump, JVM core dump, and heap dump). 
  • Use IBM Support Assistant.
