• Strong Knowledge of RAC, identifying performance issues, isolating issues, identify performance issue pattern, discussing with SME and get the server/application tuned for performance improvement.
• Have good understanding of Dynatrace for monitoring server recourses (CPU, Memory, Thread Pool and Connection Pool) tracking end to end transaction activity (right from the app server component like servlet/JSP, EJB connection to DB server response etc) and identifying performance bottleneck. Identified Memory usage/Memory leak issue, Connection pool and Load balancing issue.
• Have good understanding of Splunk for application performance monitoring.
• Involved in UNIX (Command to get server logs) and Windows (Perfmon) server monitoring.
• Contributed to standardizing best practices document.
• Responsible for End to End performance testing( writing the strategy, defining test scope, preparing test plan, designing test scenario, running the performance test, doing active monitoring and identifying root cause of performance issue, highlighting to respect team and getting fixd before going for next run. Preparing test completion report)
• Understanding business requirements and specifications, understand the application architecture.
• Collecting production and test environment details understand application usage model and define performance test objectives accordingly.
• Developing load test strategy (Baseline, Peak, Soak, Capacity assessment) and prepare the performance assessment plan.
• Creating the scripts using Virtual User Generator.
• Creating load test scenarios in performance center as per test objectives.
• Monitoring Websphere Application server component using Wily.
• Collecting and analyzing Client side matrics (response time, errors, application under load and other essential graphs) and Server side statistic (GC/ Heap dump)
• Identifying performance improvement areas.
• Logging and maintaining defect repository, and running effective triages for priority based defect resolution.
• Participating in proactive initiatives around improvement in performance of the overall application.
• Work closely with different functional groups to resolve issues, ensure thorough testing from a business perspective, release high quality products to production.
• Rerun the same scenario after implementing the suggestions to check the improvements in performance.
• Preparing performance test summary report and final test completion report.
• Identified the memory leak during soak assessment; memory utilization was increasing gradually with time in stable user load.
• Identified the load balancing issue.
• Identified the chunk of unnecessary data was submitted while saving client data.
• Identified the DB query issues with the help of Wily introscope.
• Identified increases in existing connection pool size since required connections were not available in pool and ‘ConnectionWaitTimeout’ exception is caught by the application.
• Developed Error Analysis Tool which is used to identify actual errors occurred in failed transactions during performance assessment which cannot done by HP Analysis tool.
• Developed Script verification Tool which helps to verify the Vugen scripts against scripting standard best practises.
