BMC Subsystem Optimizer Reduces Mainframe Software License Costs

HOUSTON, Sept. 9, 2014 (GLOBE NEWSWIRE) -- BMC Software today announced a new software solution that reduces the need for multiple mainframe subsystems – lowering mainframe monthly license costs (MLC) by as much as 20 percent or more on typical configurations.

The new software – BMC Subsystem Optimizer for zEnterprise® – removes the traditional requirement that DB2®, IMS™ and CICS® subsystems must reside on the same logical partition (LPAR) to communicate and process workloads. Overcoming this requirement translates to significant MLC savings.

Many mainframe shops are charged for subsystems based on the usage of all subsystems and work located on a partition. Therefore, subsystems that process less work and do not significantly contribute to the monthly peak are charged at much higher rates than their actual usage. zEnterprise® system customers can now significantly reduce MLC charges by reconfiguring their subsystem placement across partitions, using the BMC Subsystem Optimizer software to re-direct work. The solution also provides new configuration options to better manage transaction processing requirements. Because many customers have multiple DB2, IMS or CICS subsystems – and the cost of subsystems increases 12-15 percent per release – the savings from subsystem optimization can add up quickly. This can translate to millions per year that can be used for IT transformation initiatives.

The BMC Subsystem Optimizer solution is transparent to databases and applications, requiring no changes to application code. By removing the subsystem location dependency, Subsystem Optimizer provides flexibility as well as enhanced recovery and workload-balancing options. Subsystem Optimizer also lowers business risk by enabling workloads to be re-directed upon a system failure.

Key Facts

  • Mainframe shops spend roughly 30 percent of their budget on mainframe software licensing costs, which are rising each year.
  • BMC Subsystem Optimizer for zEnterprise® overcomes high MLC charges by enabling customers to redirect work to DB2, IMS, and CICS subsystems on different LPARs and central processing complexes – helping to reduce overall service unit consumption and monthly license costs.
  • BMC Subsystem Optimizer enables data requests to be re-directed for more efficient processing, without the need to modify applications.
  • BMC Subsystem Optimizer reduces business risk by ensuring that calls to DB2 and IMS can always be delivered to a subsystem on other partitions.

Supporting Perspectives

Bill Miller, president, zSolutions and Select Technologies, BMC Software:

"This is tremendous innovation in the mainframe space that we believe will excite mainframe IT leaders, helping them to reduce monthly license costs and giving them an option that they didn't have before. Subsystem Optimizer, combined with the other new products we've introduced in the last year, offers customers a fast path to lowered mainframe costs, reduced risk and increased staff productivity."

Tim Grieser, program vice president, Enterprise System Management Software, IDC:

"Customers tell us that mainframe monthly license costs remain a key concern. By introducing Subzero to help manage subsystem configuration and optimization, BMC is giving mainframe IT another tool to help lower license costs and configure high-transaction environments."
