MAINFRAME WORKLOAD OPTIMISATION
Trapped Between Two Undesirable Choices
Buy More Mainframe Capacity
Add hardware or pay overage fees to keep pace with growing COBOL workloads, driving up MIPS and MSU-based software costs.
Rewrite or Replace COBOL
Undertake a risky, multi-year rewrite or migration of proven business logic just to free up processing capacity.
Neither addresses the real constraint: general processor capacity consumed by COBOL batch.
Modern organisations need a way to free that capacity without new hardware spend or code risk.
Capacity Upgrades Are Costly. Rewrites Are Risky.
Additional Hardware & MIPS Capacity
- Drives up software licensing costs tied to MIPS and MSU consumption
- Capital expense with long procurement and approval cycles
- Doesn’t reduce the underlying workload, just delays the ceiling
- Cost keeps compounding as batch volumes keep growing
Rewriting or Replacing COBOL
- Millions of lines of proven business logic must be re-validated
- High risk of introducing defects into mission-critical batch jobs
- Multi-year investment before any capacity is actually freed
- Specialist COBOL skills are increasingly scarce to support a rewrite
A Workload Redistribution Strategy
JOPAZ compiles COBOL workloads into zIIP-eligible Java bytecode — shifting high-utilisation batch processing off the general processor without changing a line of code.
Keep Your COBOL, Change Where It Runs
COBOL source code stays exactly as it is, maintained with the same familiar development tools your team already uses.
JOPAZ redistributes processor-intensive batch jobs to the IBM zIIP specialty engine, freeing general processor capacity instantly.
Significantly Reduces Cost and Risk
- Realises up to 80% CPU savings on batch COBOL workloads at execution
- Avoids costly hardware upgrades and MIPS/MSU licensing overages
- No code changes, data migration, or downtime required
- Transition workload at your own pace, application by application
Capacity Redistribution, End to End
COBOL batch workloads compiled and redistributed to free general processor capacity.
