If you're ever in need of a solution to monitor and log the status of VPC tunnels back to another data center or office, my gist below will be right up your alley. It uses
Oracle ORION is a powerful tool for evaluating realistic OLTP and DSS/DW I/O performance. ORION should be a part of every Oracle professional's toolkit for build QA and performance tuning. I've previously used it on this blog to show the performance of Amazon's hi1.4lxarge SSD-backed instances and newer hs1.8xlarge instances with 117GB of RAM and 48TB of
Benchmarking I/O with Oracle ORION is an important part of planning, baselining, and performance-tuning Oracle environments. I've previously provided ORION results for the hi1.4xlarge SSD-backed instance class, and based on some recent work, I wanted to provide an update for the newer hs1.8xlarge instance class. Below you'll find hs1.8xlarge Oracle ORION benchmark results with the following
