1. Upgrade & Migration (12c to 14c Focus) • End-to-End Upgrades: Lead the upgrade lifecycle of Oracle WebLogic Server, SOA Suite, and OSB from version 12c to 14c (e.g., 14.1.2.x).

• Architecture & Strategy: Design and execute side-by-side migration strategies as well as in-place upgrades. Build and configure new WebLogic 14c domains and clustered topologies.

• Schema Upgrades: Execute and troubleshoot pre-upgrade readiness checks, and use the Repository Creation Utility (RCU) and Upgrade Assistant (UA) to upgrade database schemas and migrate in-flight instance data .

• Domain Reconfiguration: Reconfigure existing 12c domains to point to new 14c Oracle Home directories, ensuring Java compatibility (JDK 11+) and resolving deprecated API/feature conflicts .

• Testing & Cutover: Support upgrade testing, cut-over planning, disaster recovery validations, and rollback strategies to ensure platform stability. 2. Middleware Engineering & Administration

• Configuration Management: Provision, configure, and administer WebLogic Managed Servers, Node Managers, clusters, JMS modules, JDBC data sources, and security realms .

• SOA & OSB Administration: Manage Oracle SOA Suite (BPEL, Human Task, Business Rules) and Oracle Service Bus (OSB) endpoints, routing rules, and transformations .

• Performance Tuning: Monitor system performance, optimize JVM heap sizes, garbage collection parameters, and WebLogic thread pools for highly concurrent SOA workloads.

• Security & Compliance: Ensure security configurations, LDAP/Active Directory integration (e.g., dedicated LDAP authenticators), SSL certificate updates, and compliance standards are rigorously met . 3. Operational Support & Automation

• Deployment & CI/CD: Partner with DevOps teams to automate the provisioning and deployment of BPEL/OSB composites using WLST, Jenkins, Git, and Shell/Python scripting

. • Incident Management: Troubleshoot and resolve complex deployment, runtime, network, and database connectivity issues affecting mission-critical integrations.

• Documentation: Create and maintain robust operational standards, configuration procedures, and runbooks detailing the 14c topology and troubleshooting guidelines

. Required Skills & Qualifications

• Experience: 7+ years of dedicated experience in Oracle WebLogic Server and Oracle SOA Suite administration.

• Upgrade Expertise: Proven, hands-on experience performing WebLogic and SOA domain migrations/upgrades (specifically 12c to 14c, or extensive 11g to 12c experience with 14c readiness) .

• Technical Stack:

• Deep knowledge of Oracle WebLogic Server (12c/14c), Oracle SOA Suite, and Oracle Service Bus (OSB)  .

• Proficiency in Java runtime version upgrades (transitioning to JDK 11+) and validating compatibility.

• Strong Linux/Unix administration skills, including Bash/Shell scripting and WLST (WebLogic Scripting Tool)  .

• Database Knowledge: Understanding of Oracle Database interactions with middleware, including RAC, Grid, RCU schema management, and connection pooling.

• Problem Solving: Excellent analytical skills to diagnose stuck threads, memory leaks, and SOA composite runtime faults. Preferred Qualifications (Nice to Have)

• Experience extending SOA domains with Oracle Enterprise Scheduler (ESS) or Business Activity Monitoring (BAM) .

• Familiarity with Cloud infrastructure (Oracle Cloud Infrastructure - OCI, or AWS).

• Experience with Infrastructure as Code (IaC) tools like Terraform or Ansible.

• Oracle WebLogic or SOA Administrator Certifications
