Capgemini Under The Guidance of Navin Kumar (Senior Consultant) Capgemini India, Pune 3. Mainframe The Mighty Beast 1 Super Computer 2 Mainframe 3 Mini Computer 4 Micro Computer 4. Stable Backward Compatible ReliableSince 1960s Secure Never Hacked Mainframe Some Facts. 70% of entire data of the planet is stored on Mainframe. Can Support more than 25000 users simultaneously It takes 3 Days to Boot-up Takes a month to install and customize a basic OS. Can process 450 millions of transaction per day No virus ever attacked on Mainframe. 5. Technologies Used Operating System z/OS Programming Language Cobol Database DB2 Transaction Server CICS Program Controller JCL 6.
