: Beyond basic clusters, advanced management includes configuring dynamic clusters and session replication to handle failover seamlessly. It also involves setting up whole server migration or service-level migration to recover from hardware or software failures automatically.

WebLogic 12c introduced several features specifically aimed at modern, often cloud-based, enterprise infrastructures: Oracle WebLogic Server 12c Advanced Administrat...

Expert-level administration of WebLogic 12c involves several critical subsystems and techniques to maintain enterprise-grade "RASP" (Reliability, Availability, Scalability, and Performance). Key tasks include analyzing JVM garbage collection (GC)

: Advanced administrators leverage the WebLogic Scripting Tool (WLST) to automate repetitive tasks like domain creation, application deployment, and resource monitoring. This is often preferred over the graphical console for consistency across environments. : Beyond basic clusters

: Using the WebLogic Diagnostic Framework (WLDF) , administrators monitor server health and create diagnostic images. Key tasks include analyzing JVM garbage collection (GC) logs , heap dumps, and thread dumps to resolve performance bottlenecks like memory leaks or stuck threads. Advanced Features in WebLogic 12c

: Integrating Oracle Coherence allows for distributed data caching and managed session persistence across the environment.

: Advanced techniques include production redeployment (rolling out new versions without downtime) and the use of deployment plans to customize application configurations across different environments.
