The Data Mart was running faster than necessary and gobbling up too many resources. By slowing it down we were able to significantly improve the performance of the other workloads.Note that the red bars are exactly the same results as slide 18, except the vertical scale is different, due to the extreme performance of the Data Mart without resource management.
When the workloads are run in combination with all the Exadata features enabled we return to near baseline performance.

Approved via Bob Dunsby and Vocalink, per below.Martin is happy with the quote below however a couple of points1) Processing is in Krona which is 1Euro to 9 Krona, however whatever currency you measure this in its billions.2) I am unsure how many batches they run in a day but even at 1 we must be looking at some thing in the region of $500M per day. (Martin is going to comeback on that though)Many thanksBob.Our critical electronic payments service has been live on Exadata since early 2011 with 100% uptime. The service reliably processed the transfer of billions of Euros in the last year and achieved subsecond response times for online enquiresAnswers to questions. 1. Peak transaction volumesWe have processed a peak of 15 million items for Direct Debits and 1.5 million items for Credits. These are load processing see 6.2. Did transaction response time improve when you went to Exa, It was more that the Webservices online queries where not affected by the projected uplift of peak items to 20 million items3. SLA Yes 99.99 for the Availability – this does not include planned downtime.4. Versions188.8.131.52 BP17 and 184.108.40.206.55. Response time breakdown We haven’t actually broke in down as the measurement for response time is always measured at the outbound point.6. Max transaction rates The system has been tested to the theoretical 20 million items for a processing cycle – this has various SLA’s for the different phases but critically this has to be completed within 60 mins.7. Transaction Euro/$/Krona Not sure at the moment, i will try and get the details for you
Engineered Systems enforce standardization and built-in best practices. They support all workloads so you can address all needs with a small set of systems. Because all customers run the same configurations, you benefit from anything we discover anywhere.
This phase will leverage the database features that were deployed in the consolidation phase. What’s new will be management tools (e.g. for metering and chargeback) and the use of dynamic services (e.g. QoS on engineered systems). Agility = SLAs vs. “how much cpu do I have”
