OSP #3a: Build a Standard Cluster Platform

This is the fifth article in a series called Operationally Scalable Practices. The first article gives an introduction and the second article contains a general overview. In short, this series suggests a comprehensive and cogent blueprint to best position organizations and DBAs for growth.

We’ve looked in some depth at the process of defining a standard platform with an eye toward Oracle database use cases. Before moving on, it would be worthwhile to briefly touch on clustering.

Indexing Foreign Key Constraints With Bitmap Indexes (Locked Out)

Franck Pachot made a very valid comment in my previous entry on Indexing Foreign Keys (FK) that the use of a Bitmap Index on the FK columns does not avoid the table locks associated with deleting rows from the parent table. Thought I might discuss why this is the case and why only a B-Tree index does […]

How important is a Disaster Recovery site for you?

I regularly read threads on the oracle-l mailing list, and occasionally feel very tempted to reply to one. Just recently I saw one that I liked a lot. It is specifically about using an Oracle Database Appliance (ODA) as a Disaster Recovery (DR) solution for an Exadata system. The Exadata configuration was not specified, I assume it was a smaller (eighth rack/quarter rack) configuration.

There were lots of arguments pro and against that Exadata->ODA architecture, and that leads to a broader question: how important is DR for your organisation? This blog post is about my personal experience, and probably strongly influenced by where I live in work (Europe), yours might be different.

Boston Oracle User Group Session: Oracle 12c Features You Should Know

Thank you for all those who attended the session, and braved it up to 10 PM. Much much appreciated.

Download the slides here, and scripts I used for the demos here.

As always, your feedback will be highly appreciated.

KeePass 2.26 Released

KeePass 2.26 has recently been released. I would suggest going with the portable version, which is an unzip and go application.

If you want to know how I use KeePass, check out my article called Adventures with Dropbox and KeePass.

Cheers

MobaXterm 7.1 Released

If you are using a Windows desktop, you need MobaXterm in your life! Version 7.1 has recently been released…

I know you think you can’t live without Putty, Cygwin and/or Xming, but you really can. Give MobaXterm a go and I would be extremely surprised if you ever go back to that rag-tag bunch of apps…

Cheers

PS. Includes “Updated OpenSSL library to 1.0.1g (for “Heartbleed Bug” correction)”

WordPress 3.9 Released

Hot on the heels of WordPress 3.8.3 comes WordPress 3.9! The downloads and changelog are in the usual places.

I’ve just manually initiated the auto-update on five blogs and all went through OK.

Cheers
