SCALING ORACLE DATABASE
EXECUTIVE SUMMARY ORACLE DATABASE AT UP TO 93% OF BARE METAL

The goal
The performance of Oracle database workloads was

Why should I care?
Scale-up of a single VM with 2, 4, 6, or 8 vCPUs yields good
OLTP is mon database implementation exercising scaling. As vCPUs are added, throughput per vCPU
