01 / Why FlexNet
Led by a practitioner from the console, not a presenter with slides
Every course is led by an engineer who works on enterprise clients' production environments that same week. We don't cover textbook theory — we show configuration, logs, failures, rollback and post-deployment change validation.
- 60%Hands-on work on a prepared Linux environment, not a slideshow.
- L2/L3Program built for operational roles, application support and deployment teams.
- RealFailure scenarios, root-cause diagnostics and maintenance procedures.
- OutcomeFewer escalations, faster diagnostics and a more self-sufficient team.

Administration JMS
4 740 PLN
Outline and details
Configuring and programming Java Message Service on IBM WebSphere Application Server 7: service integration bus, queues, topics, transactions and integrations. Hands-on lab environment.
Course outline
- 1. Introduction to JMS — what JMS is and why it matters; point-to-point (queue) and publish/subscribe (topic) models; core concepts and terminology.
- 2. Service integration bus — what the SIBus is; bus members and messaging engines; message store (file store vs data store); bus topologies in an ND cell.
- 3. JMS provider configuration — default messaging provider; queue and topic connection factories; bus destinations and their JMS mappings; JNDI.
- 4. WebSphere MQ integration — MQ link and MQ client as a JMS provider; when to use the bus and when MQ; interoperability pitfalls.
- 5. Programming JMS applications — sending and receiving messages; transactions and acknowledge modes; message driven beans and activation specifications.
- 6. Reliability and delivery — reliability levels; persistent and non-persistent messages; exception destinations; retry and poison messages.
- 7. Administration and diagnostics — monitoring queues and messaging engines; wsadmin (Jacl/Jython), konsola administracyjna; browsing and deleting messages; common failures in the logs.
- 8. Performance and tuning — listener pool and thread sizing; batching; message store tuning; scaling the bus and its throughput impact.
Requirements
A machine with 4 GB RAM / 10 GB disk (Windows, macOS or Linux). Basic application server terminology and terminal skills are a plus.

Diagnostics and troubleshooting
4 740 PLN
Outline and details
Diagnosing and troubleshooting IBM WebSphere Application Server 7: logs and FFDC through JVM, JDBC, clusters and security. Hands-on work on real failure scenarios.
Course outline
- 1. Problem determination method — isolating the layer (network, plug-in, container, application, database); collecting evidence before restarting; assembling a MustGather for IBM support.
- 2. Logs and traces — SystemOut.log, SystemErr.log i trace.log (HPEL dopiero od 8.0); trace levels and groups; enabling trace without a restart; rotation and retention.
- 3. FFDC — first failure data capture: where it lives, how to read it, what a repeating incident means; correlating FFDC with application exceptions.
- 4. JVM diagnostics — javacore and thread dumps: reading thread states and deadlocks; heapdumps and memory leak analysis; GC logs and pause interpretation.
- 5. Server and profile problems — server will not start: port conflicts, permissions, corrupted config repository; node agent synchronisation with the deployment manager.
- 6. Application problems — deployment and class loader issues (order, isolation, library conflicts); hung requests; ClassNotFound and NoClassDefFound in practice.
- 7. JDBC and transaction problems — connection pool exhaustion; StaleConnectionException; timeouts and XA transactions; heuristics and transaction logs.
- 8. ND environment problems — clustering and session replication; plug-in and request routing; Web server plug-in i IHS jako front; failover and asymmetric node symptoms.
- 9. Security problems — LTPA and expired tokens; SSL certificates, keystores and truststores; LDAP integration and common authentication failures.

Monitoring and tuning
4 740 PLN
Outline and details
Monitoring and performance tuning for IBM WebSphere Application Server 7: PMI, thread pools, JVM, JDBC and the HTTP layer. Built on measurement, not guesswork.
Course outline
- 1. Tuning method — measure before changing; one variable at a time; baselines and acceptance criteria; why copying someone else settings backfires.
- 2. PMI — performance monitoring infrastructure: collection levels, the cost of enabling them, choosing counters that match the problem.
- 3. Tivoli Performance Viewer — reading counters live; recording sessions for offline analysis; spotting bottlenecks.
- 4. Request metrics — tracing a request across layers; identifying the component responsible for latency; filtering the traffic you measure.
- 5. JVM tuning — heap sizing and GC policy; GC log analysis; the pause versus throughput trade-off; production load settings.
- 6. Thread pools — web container, ORB and default pools; minimum and maximum sizes; symptoms of over- and under-sizing.
- 7. JDBC connection pools — pool size relative to thread pools; connection, unused and aged timeouts; prepared statement cache.
- 8. Sessions and caching — session management and its cost; session replication in a cluster; DynaCache and response caching.
- 9. HTTP layer — web server plug-in and IHS: keep-alive, connection counts, load balancing; Web server plug-in i IHS jako front.
- 10. Load testing — designing the scenario; interpreting results; telling an application problem from a server problem.
