Test 806: IBM WebSphere Application Server Network Deployment V6.1, Advanced Administration


Overview Objectives Test Preparation

The test consists of seven sections containing a total of approximately 52 multiple-choice questions. The percentages after each section title reflect the approximate distribution of the total question set across the sections.

Section 1 - Architecture (15%)

  1. Assess the relationships between WebSphere Application Server and related components (e.g. browser, HTTP server, plug-in, firewall, database servers, WebSphere MQ, load balancing and IP spraying).
  2. Evaluate the design considerations of WebSphere Application Server installations in an enterprise application environment (e.g. LDAP, database servers and JMS).
  3. Evaluate the architecture of the federated topology relative to the base install, including effects of adding nodes to cells (e.g. application and configuration synchronization issues).
  4. Develop workload management and failover strategies using WebSphere Application Server.
  5. Assess usage of WebSphere Application Server dynamic caching features.

Section 2 - Installation/Configuration of Application Server (8%)

  1. Develop installation strategies (e.g. silent install, required/desired plug-ins and profiles).
  2. Define WebSphere Application Server installation verification strategies.
  3. Define custom installation packages using Installation Factory.
  4. Validate the installation.

Section 3 - Application and Server Resource Configuration (12%)

  1. Define name space management strategies (JNDI).
  2. Configure advanced options in Ear files using Application Server Toolkit (AST).
  3. Determine and specify access strategies to enterprise information (e.g. JDBC, JMS and J2C).
  4. Design and implement automated administrative strategies and tasks through scripting.

Section 4 – WebSphere Security (15%)

  1. Design and specify cell level security policies.
  2. Evaluate advanced J2EE, Java 2 and other WebSphere Application Server security scenarios.
  3. Design and specify SSL usage with WebSphere Application Server.
  4. Design, specify and configure Federated Repositories using Virtual Member Manager (VMM).

Section 5 - Workload Management, Scalability and High Availability (19%)

  1. Define and implement highly available WebSphere Application Server enterprise solutions.
  2. Evaluate data failover options (e.g. session data, Data Replication Service (DRS) configuration and Dynacache).
  3. Design and specify WebSphere Application Server workload management strategies (e.g. plug-in, load balancers, core groups and clustering).
  4. Design and specify WebSphere Application Server scalability strategies (e.g. plug-in, load balancers, core groups and clustering).
  5. Design and evaluate highly available and scalable WebSphere Platform Messaging configurations.
  6. Determine the impact of Web server farms on workload management in WebSphere Application Servers.

Section 6 - Maintenance and Performance Tuning (19%)

  1. Provide guidance on application and server configurations (e.g. application bindings, tune HTTP session configuration parameters such as timeout value and persistence).
  2. Establish guidelines for WebSphere Application Server backup, restore and disaster recovery.
  3. Establish guidelines for monitoring the size of log files and archive/purge policies.
  4. Evaluate and manage the plug-in configuration file generation and propagation strategies.
  5. Evaluate and tune performance of WebSphere Application Server and formulate recommendations (e.g. configure caching, queuing, thread pooling parameters and plug-in).
  6. Tune WebSphere Application Server JVM configuration (e.g. JVM heap size and garbage collection).
  7. Define and tune data source configuration (e.g. Container Management Transactions (CMT), Container Managed Relationships (CMR), connection pooling and timeouts).
  8. Analyze Tivoli Performance Viewer/Runtime Advisor results and make recommendations.
  9. Evaluate and implement class loading scenarios (e.g. parent first, parent last, JNI and shared libraries).
  10. Develop and implement a maintenance application strategy (e.g. FixPacks, cumulative fixes and interim fixes).

Section 7 - Problem Determination (12%)

  1. Analyze logs and initiate corrective activity (e.g. Web server and WebSphere Application Server).
  2. Analyze the content of the JNDI namespace to resolve problems.
  3. Analyze JVM troubleshooting data (e.g. thread dump, JVM core dump, heap dump, and Class Loader Viewer).
  4. Analyze the role that networks and firewalls play in resolving WebSphere Application Server issues.
