For some clients — banking and public sector — Oracle WebLogic is the only acceptable choice. The Oracle stack with full support and certification. After a year, we share our experience.
Why WebLogic¶
The client requires the Oracle stack. Certification for Fusion Middleware and SOA Suite. Enterprise features: Coherence cache, JMS clustering, WLST scripting. Oracle support.
WLST¶
A Jython-based scripting tool. All configuration can be scripted — datasources, deployments, security. Versioned in Git, executed from Jenkins. Reproducible deployment.
Clustering¶
Robust session replication, whole server migration, service migration. The Admin Server centrally manages the cluster. Node Manager automatically restarts crashed managed servers.
Oracle Stack Integration¶
Oracle JDBC with UCP — connection affinity for RAC, Fast Connection Failover. Coherence as a distributed cache.
Licensing¶
Per CPU. For clients with an Oracle EE license, WebLogic Suite is included. For others, it’s a significant investment. GlassFish or JBoss are free — consider whether you truly need the Oracle stack.
Conclusion¶
WebLogic is an enterprise beast — robust, feature-rich, expensive. A logical choice for the Oracle ecosystem. For everyone else: JBoss/WildFly offers 90% of the features at a fraction of the cost.
