Faster financial transactions with mainframe

Driving up to 25% faster transactions for Union Investment through mainframe modernization

Mainframe powers Union Investment’s future

T-Systems modernized Union Investment’s mission-critical mainframe, ensuring scalability, security, and resilience. The DASKA clearing system now handles vast transaction volumes seamlessly, supporting digital services and customer demands. This optimized architecture safeguards performance, reliability, and long-term stability in Union’s fast-evolving financial environment.

Customer pain points

  • Speed up financial transactions, especially for investors
  • Minimize latency
  • Satisfy compliance requirements (such as BaFin)
  • Enable smooth cooperation with partners (including Deutsche Börse, Atruvia, Ratiodata, and DZ Bank)

How T-Systems solved it

  • Modernized the mainframe system through a 1:1 migration of the DB2 database (from IBM z14 to IBM z16)
  • Conducted comprehensive test runs and relocated the mainframe platform from Munich to Frankfurt
  • Migrated 80 TB of data from Munich to Frankfurt smoothly
  • Utilized a new feature: geographically dispersed parallel sysplex
  • Ensured that during updates, a “shadow system” takes over operational tasks

The new mainframe architecture and the move to Frankfurt have given us, our customers, and our finance partners a clear boost in performance. Transaction speed has increased by up to 25 percent, while system-related downtimes have dropped significantly.
