CHU de Bordeaux: Oracle Migration to New Infrastructure

Bordeaux University Hospital: Oracle migration to new infrastructure

To guarantee 24/7 availability of patient records, Bordeaux University Hospital commissioned DEEP to modernize the infrastructure and migrate 19 TB of Oracle databases from AIX to Oracle Linux RAC, securing vital data for 9,000 users, without any major disruption.

Context and challenges

With more than 3,000 beds, 100,000 annual emergency room visits and 540,000 consultations, the University Hospital needed to modernize its IS from an active/passive AIX cluster to an active/active Oracle Linux architecture, while limiting downtime.

Customer's activity:

Bordeaux University Hospital is a leading teaching hospital in the South-West of France. On a daily basis, it processes a critical volume of medical data concerning thousands of patients.

Method of support :

DEEP acted as a consulting partner: audit, infrastructure design, migration plan and 24/7 support. Teams were also trained to increase their skills and ensure post-project autonomy.

Feedback from Bordeaux University Hospital

Mission objectives

Minimize service interruptions: aim for an outage of less than 7 hours for the final switchover.
Restore access to applications for 9,000 users at the end of the migration.
Switch to an active/active Oracle Linux cluster to improve resilience and performance.
Transfer skills to in-house DBAs to ensure autonomous operation of the new platform.

Support process

Analysis of AIX workloads, definition of Intel/Linux servers, choice of Oracle RAC and high-availability ASM storage.

Installation of a test cluster, blank migrations, validation with supervision tools and coaching of CHU DBAs.

Incremental backups, cross-platform RMAN conversion, nightly switchover: reduced unavailability at 6 a.m., then full opening at 6.15 a.m.

Customer benefits

Increased 24/7 availability - meticulous preparation minimized final downtime to 6 hours.
Optimized application performance - improved response times on the new Oracle 19c/Linux stack.
Scalable & robust platform - scalable Linux/Intel architecture, ready for future version upgrades.
Cost control - rationalize licenses and maintenance by switching to standard hardware and Oracle RAC.
