Architectural and Performance Considerations for Java Applications on z/OS

Abstract Java applications executed on IBM z/OS platforms benefit from the mainframe infrastructure's reliability, scalability, and security. However, attaining optimal performance requires more than conventional tuning techniques. [1][6]
This paper presents a research-oriented examination of optimization strategies and architectural trade-offs relevant to Java workloads on z/OS. Rather than prescribing specific configurations, a spectrum of performance approaches is surveyed—these range from low-level JVM parameter adjustments to high-level architectural and subsystem integration strategies.
This paper evaluates the execution contexts of both CICS-integrated and standalone Java applications, examining the roles of z Integrated Information Processors (zIIPs), garbage collection behaviors, thread models, file input/output practices, and DB2 connectivity models. Attention is also given to the interplay between resource efficiency and development agility, positioning performance choices as critical architectural decisions.
This paper aims to provide a structured discourse on Java performance strategies within the z/OS ecosystem through case studies, tool assessments, and conceptual models.
