Performance Tuning Service for IBM Mainframe
Isn't "Cost Containment" at the top of the agenda for every CIO these days?
BUSINESS CHALLENGE
• Despiste all the recent technological advances, much of the critical work for the business is still processed in the Mainframe World.
• MIPS growth is a good indicator of actual growth because users pay for systems based on MIPS capacity and the MIPS growth is based on incremental MIPS added.
• Considering the high cost per MIPS, and the workloads on Mainframe growing 20-30% every year, MIPS reduction becomes a viable strategy to reduce the costs.
• Many procedures (COBOL/SQL/JCL), althought operating correctly, have been in service for many years and have not benefited from advanced best coding practices or processing methods.
• Performance "ignorance" reduces application availability, causes an escalation in costs due to extraneous processing, surges in batch processing with excessive CPU utilization and unnecessary job wait time.
• Thus performance tuning assumes a new significance not only due to tight economic conditions, but also due to proliferation of batch jobs, multiple test environments, sub-systems/shared resources.
How can CIOs contain costs through performance tuning?
RECOMMENDING A STRATEGY
• Reduce your CPU-time, ELAPSED-time, I/O and DASD consumption.
• Increase performance that results in MIPS reduction.
• Save money by extending the life of current hardware investments.
• More workload to be processed without adding additional resources.
• Reduce operating costs.
• Allow for growth.
