15 years maintaining WAS clusters for banks, telcos and insurers. We take over the cluster — from installation to Liberty migration — and your team gets back to projects. IBM Certified System Administrator, audit quote in 24 h.
From first profile installation to Liberty migration. We work like production engineers — not presentation consultants. Certified team, 15 years with WAS.
WAS 7 → 8.5 → 9 in-place or side-by-side. Plus WAS Classic → Liberty Profile with binary scanner, server.xml refactor, feature manager. Rollback plan, smoke tests, 30-day post-migration monitoring.
Profiles (Application Server, Deployment Manager, Custom, Cell), node federation, security domain, SSL keystores, JDBC providers, JMS modules.
ND Cell with Deployment Manager, app server clusters, session replication (memory-to-memory or DB), failover, IBM HTTP Server + plugin-cfg.xml.
JVM (-Xms/-Xmx, GC IBM Generational/balanced/Z), thread pools (Web, ORB), JDBC connection pools, EJB pool sizes, session timeout, HTTP plugin tuning. PMI metrics + Tivoli Monitoring.
IBM MQ (WebSphere MQ) integration, queue managers, channels, JMS bus, Message Broker / Integration Bus, foreign bus, distributed JMS destinations.
LTPA tokens cross-cell, federated repositories (LDAP + Active Directory), SAML SSO, OAuth, J2C aliases, role-based access, IBM Fix Pack security patches.
PMI (Performance Monitoring Infrastructure), IBM Tivoli, Health Center, Verbose GC analysis. Integration with Prometheus/Grafana/Splunk for modern teams.
Body leasing of a WebSphere administrator or full ND cluster maintenance outsourcing. Fixed rates, monthly reports, SLA and penalties agreed in the contract.
Describe the problem — an engineer replies within 24 h, not a salesperson.
Write to an engineerAll WAS versions currently maintained for clients. We can help you stay on Classic or migrate to lightweight Liberty Profile — depending on your needs.
Latest Classic version. Java EE 8 support, MicroProfile, K8s integration, OpenJ9 JVM. Continuous Delivery (CD) — fix packs every quarter.
Most common version in Polish banking and telco clusters. Network Deployment, intelligent management, SCA. IBM support with no announced end date.
Still running in older administrative systems and some banks. We support maintenance + migration to 8.5/9 or Liberty without downtime.
Lightweight, modular alternative to Classic. Feature manager, server.xml configuration, Docker-friendly, K8s operator. Ideal for microservices.
Three answers — a preliminary risk rating and target based on IBM's support lifecycle. The final one comes from an application assessment, not from a promise that nothing in the code will change.

binaryAppScanner to detect features required by the application, (2) refactor server.xml with appropriate feature managers (e.g. jpa-2.2, servlet-4.0, ejbLite-3.2), (3) migrate JNDI bindings, JDBC, JMS resources, (4) regression tests + performance comparison Classic vs Liberty. Typically 2–4 weeks for a standard JEE application. Benefit: 50–70% less RAM, ~5x faster startup, easier K8s deployment.-Xms/-Xmx, GC algorithm (gencon for most, balanced for large heap, metronome for low-latency), Verbose GC analysis. (2) WAS — thread pools (Web Container, ORB, Default), JDBC connection pools (initial/max/test on reserve), EJB pool sizes, session timeout, plugin-cfg.xml retry/maxConnections. (3) Application — query optimisation, prepared statement cache, lazy loading EJB. (4) OS/net — AIX vmo/no/ioo, Linux sysctl, NFS sync. Every change measured before/after (PMI + thread dumps + heap dumps with IBM HeapAnalyzer).Five commands, five minutes.
