๐น Key Features:
Monitors job logs in SDSF
Parses logs to detect abends (S0C7, S222, S322, etc.)
Sends automatic alerts to support teams
Reduces downtime and manual monitoring efforts
๐น Impact: Reduced batch processing failures by 30%, improving system uptime.
2. Policy Renewal Automation for Insurance Systems
๐ Tech Stack: COBOL, JCL, DB2, CICS, VSAM
๐น Overview: Automate policy renewal and premium calculation for an insurance client.
๐น Key Features:
Fetch policy details from DB2 tables
Check eligibility and apply premium rate adjustments
Generate renewal notices and update the VSAM file
Process bulk renewals via a scheduled batch job
๐น Impact: Improved efficiency of policy renewals by 40%, reducing manual intervention.
3. Mainframe to Cloud Data Migration
๐ Tech Stack: COBOL, JCL, DB2, AWS S3, Python (for data validation)
๐น Overview: Migrate data from mainframe DB2 tables to AWS S3, enabling a hybrid cloud approach.
๐น Key Features:
Extract DB2 tables using COBOL/JCL
Convert data format (EBCDIC to ASCII)
Validate data using Python scripts
Upload to AWS S3 via FTP
๐น Impact: Reduced mainframe storage costs and enabled real-time data access in the cloud.
4. Fraud Detection System for Banking Transactions
๐ Tech Stack: COBOL, CICS, DB2, REXX, MQ Series
๐น Overview: Develop a fraud detection module to identify suspicious banking transactions in real-time.
๐น Key Features:
Implement fraud detection rules (high-value transactions, unusual locations, etc.)
Use CICS screens to flag high-risk transactions
Generate real-time alerts via MQ messaging
๐น Impact: Reduced fraudulent transactions by 25%, improving security and compliance.
5. End-to-End Claims Processing System for Insurance
๐ Tech Stack: COBOL, JCL, DB2, CICS, IMS DB
๐น Overview: Automate the claims processing lifecycle, from submission to settlement.
๐น Key Features:
CICS screen for claims entry
Auto-verification of customer policy details
DB2 backend for claims storage
Batch job to generate claim settlement reports
๐น Impact: Reduced claims processing time by 50%, enhancing customer satisfaction.
6. Customer 360ยฐ View Dashboard (CICS Application)
๐ Tech Stack: COBOL, CICS, DB2, Web Services
๐น Overview: Develop a CICS-based dashboard that provides a 360-degree view of a customerโs profile, transactions, and history.
๐น Key Features:
Fetch customer details in real-time from DB2
Display last 10 transactions on a CICS screen
Allow authorized users to update customer details
๐น Impact: Improved customer service response time by 35%.
7. Mainframe Performance Optimization & Tuning
๐ Tech Stack: COBOL, JCL, DB2, SMF Reports, REXX
๐น Overview: Optimize long-running batch jobs and high CPU-consuming CICS transactions.
๐น Key Features:
Analyze SMF records for CPU & I/O performance
Optimize inefficient SQL queries in DB2
Implement buffering and indexing for DB2 performance
๐น Impact: Reduced CPU utilization by 20%, saving infrastructure costs.
