Oracle Engineering Systems (Community) Day

On a full room in the centre of Zurich, Switzerland, two great events dedicated to ODA, Exadata, ExaCC, Exadata at OCI or Azure, PCA and other derivatives took place on March 20th 2024. In the morning organized and sponsored by Tradeware AG was the 21st Oracle Engineering Systems Community meeting, followed by 11th Swiss Oracle Engineering Systems day, organized by Oracle.

Manfred Drodz from Peakmarks showed the results of his performance benchmarks with the new Exadata X10M and how it improves up to 35% compared with X7. Peakmarks is specialized on benchmarking Oracle workloads, helping to choose the right number of CPUs needed when migrating to a new platform.

In Switzerland, Twint is a relatively new payment platform, meanwhile used by more than 50% from the population at least once a month! Erich Steiger showed us how on Exadata performance dilutes application problems, making them quite difficult to spot. But, after convincing the developers to avoid doing unnecessary queries, finally two application bugs could be found, making the existing Exadata resistant for some more years. Currently Twint is looking for the ExaCC solution and its dynamic scaling to absorb the midday peaks.

Mike Dietrich from Oracle presented the new M5 cross-platform migration script and how it was used for migrating a 200TB database from Solaris Supercluster to Exadata. More information on Mike’s website.

After lunch, Ashish Ray presented the Oracle strategy in terms of Exadata, ExaCC and AI. It presented how Oracle look forward with future ExaScale architecture which might remove the limited amount of VMs in a Exadata with its elastic infrastructure.

Swisscom – a major Swiss infrastructure provider – had Roger Fehr and Roger Staubli presenting their ExaCC strategy and how they are together with two core banking solutions (Avaloq and Finova) doing its certification against the Cloud@Customer solution.

Later in the day Marcus Praetzas from Deutsche Bank showed the converged strategy they follow and how ExaCC and Autonomous DB on Exadata allows them to have Oracle as a main database for almost all types of usage.

As a Recap of this intensive day, it was clear that many Swiss and German customers are happy with the Oracle’s Exadata Cloud@Customer solution and pretend to continue using it in their strategy.


Install Oracle Linux 9 and Oracle Database 19c on Windows WSL 1

Since a few days I’ve a Oracle Database 19c running on my laptop (4 year old i5 processor with 16GB memory) under the Windows Subsystem for Linux with the latest Oracle Linux 9.3. It is working great for testing functionalities. It survives without problem sleep and restart without first shutting down correctly the database.

While there are no snapshot possibility like with Virtualbox, it is possible to export the running image and re-import later.

Below I describe the main steps to quickly install the system.
