I/O benchmarking chat with Uday Vallamsetty from Delphix

Uday Vallamsetty from Delphix performance group just posted a great blog post on evaluating I/O performance in Amazon AWS with EBS.  I had a chance to talk with him a bit about I/O benchmarking and some of the surprises and challenges of I/O benchmarking as well as discuss the importance of producing a report card on any I/O subsystem one is using.

Interesting SLOB Use Cases – Part I. Studying ZFS Fragmentation. Introducing Bart Sjerps.

This is the first installment in a series of posts I’m launching to share interesting use cases for SLOB. I have several installments teed up but to put a spin on things I’m going to hit two birds with one stone in this installment. The first bird I’ll hit is to introduce a friend and colleague, Bart Sjerps, who I just added to my blogroll. The other bird in my cross-hairs is this interesting post Bart wrote some time back that covers a study of ZFS fragmentation using SLOB.

Delivering DBaaS using EM 12.1.0.4

One of the jobs I’m currently working on is writing a technical whitepaper on Delivering DBaaS using EM12c. I realized as I was starting it that a technical whitepaper really isn’t the place for a step-by-step how-to sort of description, so I thought I’d better blog about it instead. Actually, I’m going to write a whole series of blog posts since, much like the series of blogs Kellyn and I wrote on the EM 12.1.0.4 release, the area is so damn big it’s impossible to cover in a single blog post! So this post will be the introduction, and I will add links to the additional areas as they get covered. If you’re already following this blog, you’ll be informed of each one as it gets posted, so don’t forget to follow the blog to get the whole series!

DevOps & Delphix : Chef recipes

Delphix Engines expose all features via a stable WEB API built on top of HTTP and JSON.

Clients choose an HTTP client to interact with Delphix and integrate within their environment.

Delphix Engines are bundled with a command line interface which guides users for automation and integration with third party tools.

Enter these commands through the command line interface:

VirtualBox 4.3.14

Oracle have given birth to VirtualBox 4.3.14. Mother and baby are doing well, with the downloads and changelog in the usual places.

Happy upgrading…

PS. Looks like the baby might be still-born. Fails pretty badly on Windows 7 at the moment…

PPS. Seems to work fine on Mac and Linux (Fedora 20)…

Granting Access to BI Publisher in EM 12.1.0.4

In my Configuring Highly Available BI Publisher in EM 12.1.0.4 post, I covered how you configured BI Publisher in a highly available environment. When BI Publisher is configured, by default only the super-administrator accounts you have defined in your EM12c environment have access to the tool. That means that none of your normal administrator level accounts have access, so if you login as an administrator (rather than as a super-administrator), and try to access the BI Publisher reports, you will see a screen that includes this:
