Challenge
A Fortune 500 investment bank and long-time client urgently needed to modernize their aging IT infrastructure.
Several applications were hard-coded into company systems, and the bank heavily relied on VSAM and internal tables. This created a precarious situation.
Additionally, the team lacked experience with CICSPlex, making it difficult to understand IBM's documentation and adding complexity.
CPT Global’s Actions
CPT moved critical applications from single CICS regions to a highly available, redundant, and efficient CICSPlex environment.
Our team leveraged workload sharing and balancing to best utilize system resources and maximize performance. CPT also designed a solution to move existing hard-coded tables to a coupling facility structure with minimal application changes.
We then enabled jobs to call a transaction in any available region using the CICS CPSM API and developed a strategy for moving VSAM data sets into RLS for greater flexibility and scalability.
Finally, CPT provided webinar-based training on all aspects of this technology to educate employees and ensure successful implementation.
Results
- 2x performance improvement via CICS/VSAM/Db2, enabling double workloads.
- 9 hours saved on a single job, boosting system efficiency.
- Trained employees on z/OS systems, CICS, and MQ groups to handle all aspects of daily operations.
By partnering with CPT Global, the bank effectively accelerated its modernization efforts, achieving enhanced performance and internal expertise.
