Installing and configuring Oracle WebLogic Server on servers, setting up domain configurations, clusters, and managed servers based on application requirements.

Deploying applications (EAR, WAR, JAR files) to WebLogic Server instances, managing deployment descriptors, and configuring deployment settings such as target servers and deployment order.

Monitoring server health, performance metrics (CPU, memory, threads, JDBC connection pools), and tuning configurations (JVM settings, thread pools, connection pools) to optimize performance and resource utilization.

Configuring and managing security features such as SSL certificates, authentication providers, role mapping, and access policies to ensure secure communication and access control.

Configuring and managing WebLogic clusters, including setting up cluster communication, load balancing, and failover mechanisms (such as session replication and persistent stores) to ensure high availability.

 Implementing backup strategies for WebLogic Server configurations, application deployments, and data stores (like JDBC data sources and JMS stores) to recover from failures and ensure data integrity.

Applying patches, updates, and upgrades to WebLogic Server instances, JDK versions, and associated components to address security vulnerabilities, bugs, and compatibility issues.

Configuring log files (server logs, application logs) and monitoring tools (like WLDF – WebLogic Diagnostic Framework) to troubleshoot issues, track server activities, and analyze performance metrics.

Managing server resources such as connection pools, JMS servers, JDBC data sources, and thread pools to optimize resource usage and ensure scalability under varying workloads.

Configuring integration features like JMS (Java Message Service), JCA (Java Connector Architecture), and configuring middleware services (like Oracle Coherence for distributed caching) to support application requirements.

 Developing WLST (WebLogic Scripting Tool) scripts and automation scripts to perform routine administrative tasks, automate deployments, and streamline operational processes.

Maintaining documentation of configurations, deployments, and procedures related to WebLogic Server administration, and generating reports on server health, performance trends, and compliance.
