Rocket Performance Essential

Reduce batch processing time for IBM Z mainframes

Mainframe batch windows are under pressure from growing data volume, while processing time is constrained by SLAs or by sub-capacity license agreements. Rocket® Performance Essential significantly improves batch processing performance with improved I/O efficiency. You can automatically reduce I/Os by up to 90% within hours of installing Performance Essential—no manual performance tuning required.

Rocket Mainframe Solutions
Improve IBM Z performance

Batch windows are in the critical path of business continuity, digital transformation, application modernization, and other strategic initiatives. With Rocket Performance Essential, batch processing times and resource consumption can be cut by 50-75% without manual performance tuning. Your mainframe environment operates more efficiently, with batch I/O that is optimized automatically. Performance Essential helps lower your mainframe system overhead without modifying applications and improve data center and end-user productivity, and frees your mainframe performance team to focus on other tasks and extend the life of critical applications.

Protect your sub-capacity license agreements

Sub-capacity license agreements often require batch jobs to be completed in four hours or less. As data volumes increase, it may be difficult for some jobs to complete within that window. If you go over, your agreement may revert to a full-capacity license, costing you millions in additional license fees.

By optimizing batch I/O automatically, Performance Essential can cut batch job resource consumption and shorten the time required for jobs to complete, without requiring manual intervention from your mainframe performance team. If you’re in danger of exceeding your sub-capacity license limits, the cost savings can be dramatic.

Optimize both VSAM and non-VSAM data sets

Performance Essential optimizes batch jobs for both VSAM and non-VSAM data sets, often resulting in significant resource and time savings. It optimizes buffer allocations automatically and dynamically, enabling you to reduce EXCP counts by up to 90% without the need to analyze data access definitions and application usage patterns manually. This helps reduce processing time by up to 75%, without putting additional burden on your mainframe performance team.

With Performance Essential, your IT staff and mainframe resources will be free to focus on growth-based initiatives.
