Praveena M

• Monitored, scheduled, and restarted Pre-Prod and Test batch processing jobs using TSO/ISPF and Control-M, and executed ADHOC jobs for clients through Control-M as required.
• Collaborated with clients to schedule special and critical batch jobs, as well as ADHOC jobs, using Control-M. Conducted weekly and monthly refresh activities, along with system migrations and upgrades from production to pre-production environments, resulting in enhanced performance and reduced downtime.
• Worked extensively with DB2 and VSAM for database management, ensuring high data integrity and availability. Performed batch job debugging and testing using tools such as IBM Debugger to facilitate smooth production deployments.
• Developed and maintained COBOL programs for business-critical applications on IBM mainframes.
• Managed and optimized JCL scripts, improving batch job execution and system performance.

Technical Skills:

• Programming Languages: COBOL
• Database Systems: DB2, IMS, VSAM, SQL
• Operating Systems: z/OS, OS/390, MVS
• Tools: JCL, TSO/ISPF, CICS, SDSF, SAR, IDCAMS, SORT Version Control: Endevour
• Job Scheduling: Control-M

• Environment Management support (EMS) provides L1/L2 support for test environments which are cloned from Production environment. Cloned test environments are used by Development teams to perform unit testing end to end prior to code deployment into production environment.
• Pre-Prod Environment support: used for Client volume testing by multiple projects before approving data load into Production environment.
• Clone Production environment to Lower Dev regions by developing Jobs, PROC and Control cards.
• DB health check to ensure environment is active.
• Adhoc data refreshes on weekly/Bi-weekly basis.
• Monthly release activities: Involves Code, data refresh from Production environment to lower environments to test ongoing project changes.
• Adhoc Scheduling changes - Control-M tool.
• Adhoc application jobs execution based on business user requirement to perform volume testing
