Parallel Sysplex

BCL designs, builds, and enables Parallel Sysplex environments on IBM Z. We define the architecture, verify prerequisites, and implement the components so you have a solid, production-ready base you can expand and exploit over time. We do this all with minimal disruption and clear documentation.

About Parallel Sysplex Systems

Parallel Sysplex brings data and resource sharing, balanced multi-workload processing, and continuous availability to your mainframe estate. The result is higher productivity, protection of existing investments, and the ability to scale services without sacrificing service levels or control.

Advantages of Parallel Sysplex

System z data and resource sharing

Balancing of multiple workloads
Increased productivity
Continuous system and application availability
Investment protection and reduced software cost

BCL’s Parallel Sysplex Systems

We provide a structured set of services and specific deliverables to accelerate production use:

A migration planning session
Choosing and modifying BCL’s existing detailed System Enablement implementation plans for your system
Verifying the hardware configuration
Verifying the correct level of z/OS system, or upgrading your z/OS software installation
OEM product compatibility research
Implementing the Parallel Sysplex
Exploiting the coupling facility for XCF, RACF, JES2 checkpoint or VTAM generic resources, as appropriate
Establishing a test CICSPlex including VSAM RLS setup, DB2 data

Throughout the engagement, BCL project management and technical specialists keep the work on schedule and provide skills transfer to your systems programmers, so your team can operate and extend the sysplex with confidence.

The System Enablement phase will be complete when:

The Parallel Sysplex is active and communicating in a test environment using a coupling facility for XCF services, JES2 checkpoint, and RACF profiles, as applicable
The test data-sharing environment is available for application testing
The Migration and System Enablement plans have been documented

Why Choose BCL?

We combine disciplined project management with deep IBM Z engineering. Our enablement method keeps changes controlled, timelines predictable, and documentation clear. This is all while building your team’s capability to run and evolve the sysplex after go-live.
