Exploring Tools and Techniques of Mainframe Developer Course in Velachery

• COBOL Programming: COBOL remains a major language for developing applications that process large volumes of business transactions. Training introduces program structure, variables, conditions, loops, file handling, tables, and modular coding. Learners practice writing and executing programs while understanding how application logic is maintained. These exercises build a practical foundation for working with enterprise mainframe applications.
• JCL Scripting: JCL controls how programs and batch workloads are executed on mainframe systems. Learners work with job statements, execution steps, datasets, procedures, parameters, and output definitions. Practical exercises show how jobs are submitted, monitored, and corrected when failures occur. This knowledge helps developers manage application execution and understand dependencies within scheduled enterprise processing workflows.
• DB2 Database: DB2 provides relational database capabilities for many enterprise mainframe applications. Learners explore tables, keys, relationships, SQL statements, filtering, joins, and data updates while understanding how programs interact with stored information. Practical activities connect COBOL applications with DB2 databases, helping participants develop skills for retrieving, modifying, validating, and processing business data accurately.
• CICS Processing: CICS supports online transaction processing where applications must respond quickly to user requests. Training covers transaction concepts, program execution, screen interaction, and communication between CICS and COBOL programs. Learners compare online processing with batch execution and practice understanding transaction flows. This prepares them to develop, test, and troubleshoot applications that support real-time enterprise operations.
• VSAM Files: VSAM is widely used for organized record storage and retrieval within mainframe applications. Training introduces dataset types, record structures, keys, file operations, and application access methods. Learners practice reading, writing, updating, and locating records through practical examples. This experience helps developers understand how business applications handle structured files and maintain reliable data-processing workflows.
• TSO and ISPF: TSO and ISPF provide important interfaces for accessing mainframe systems and performing development tasks. Learners practice navigating panels, editing source members, working with datasets, submitting jobs, and reviewing results. Regular use of these interfaces improves confidence in daily development activities. Participants also learn how these environments support coding, testing, file handling, and application troubleshooting.
• JES Operations: JES manages the submission and processing of jobs within a mainframe environment. Developers need to understand job queues, execution status, spool information, output handling, and return codes. Training activities help learners follow jobs through different processing stages and identify common execution problems. This knowledge supports effective batch monitoring and quicker resolution of job-related application issues.
• SDSF Monitoring: SDSF helps developers and support teams inspect job activity, output, system information, and execution results. Learners practice locating submitted jobs, reviewing spool content, checking return codes, and identifying failed processing steps. These activities develop practical monitoring skills that are useful during application testing and production support, especially when investigating unexpected batch execution or output-related problems.
• SQL Queries: SQL is used to access and manipulate relational data stored in DB2 databases. Participants practice SELECT, INSERT, UPDATE, DELETE, joins, filtering, and conditional queries while learning how SQL interacts with COBOL programs. Hands-on database exercises strengthen their ability to work with application data. These skills are useful when developing, testing, maintaining, and troubleshooting database-driven mainframe applications.
• Debugging Methods: Debugging helps developers identify and correct problems before applications are released or updated. Learners examine program logic, job outputs, database responses, file processing, and execution errors to locate the source of issues. Practical troubleshooting activities encourage a structured approach to resolving defects. This improves confidence in maintaining application accuracy and restoring expected processing when errors occur.
