Java Production Support for Banking Systems

• An understanding of core Java programming concepts
• Experience working with Unix-based systems
• Familiarity with support workflows in enterprise applications

Audience

• Support Engineers
• Java Developers transitioning into support roles
• Production Support Analysts in banking environments

Java Production Support is the specialized domain of maintaining, troubleshooting, and ensuring the health of Java-based systems in live environments.

This instructor-led, live training (online or onsite) is aimed at intermediate-level support engineers and developers who wish to enhance their ability to maintain, troubleshoot, and optimize Java-based production systems in banking environments.

By the end of this training, participants will be able to:

• Resolve issues in Java, Unix, DB, and middleware environments.
• Use monitoring tools to identify and respond to production incidents.
• Follow proper escalation paths and document root causes effectively.
• Participate in release/rollback cycles and coordinate across teams.

Format of the Course

• Interactive lecture and discussion.
• Hands-on use of real-world support tools and systems.
• Live simulation of incidents and troubleshooting scenarios.
