Scripts to Download Oracle Database 12c Release 2 Documentation

In the past (here, here and here) I already shared with you the scripts I use to download the Oracle Database documentation. The aim of this short post is to reference the scripts I just wrote for the latest version: 12c Release 2.

Happy downloading as well as happy reading!

Oracle Documentation URLs : What I would like to see!

Broken-LinkAfter my recent rant about broken URLs, I thought it would be sensible to say something a little more constructive, so this is what I would do if I were asked to structure the documentation. Other opinions are valid. :)

Base URL: I’m assuming the base URL for the database documentation will never change again from it’s current value.

Guaranteed Method of Boosting your Oracle Skills

I can tell you how to be a better Oracle DBA, Developer, Designer, Architect – whatever your flavour of role or aspect of profession, if Oracle tech is part of your working world I can hand you the key to improvement. And it is easy.

I am totally assured(*) I can do this. It will work for every single one of you reading this post (except for you two, you know who you are). And you must send me $100 before I tell you how…

Hell, no you don’t! This is not some bull-droppings selling piece, it is just advice. And some advice aimed directly at myself too.

When did you last read the Oracle Server/Database Concepts manual? You know, that fairly short book (in fact, from 11G it is really short, with links through to other chapters in other books) that explains how Oracle TM (Copyright), actually does stuff? What it can do? It does not go into too many details but rather gives you a brief introduction of each concept and the fundamental “how it works” information.

An Oracle Instance is Like An Upmarket Restaurant

I recently did an Introduction to Oracle presentation, describing how the oracle instance worked – technically, but from a very high level. In it I used the analogy of a restaurant, which I was quite happy with. I am now looking at converting that talk into a set of short articles and it struck me that the restaurant analogy is rather good!

Here is a slide from the talk:

Scripts to Download Oracle Database 12c Release 1 Documentation

In the past (here and here) I already shared with you the scripts I used to download the documentation related to Oracle Database. The aim of this short post is to provide the scripts I just wrote for the latest version: 12c Release 1.

Happy download as well as happy reading!

PS: it is interesting to note that the number of manuals is more or less stable. Some were added (e.g. SQL Tuning Guide), some were removed (e.g. all related to OWB).

Friday Philosophy – The Tech to Do What You Need Probably Exists Already

How many of you have read the Oracle Concepts manual for the main version you are working on?

This is a question I ask quite often when I present and over the last 10 years the percentage number of hands raised has dropped. It was always less than 50%, it’s been dropping to more like 1 in 10 and Last year (at the UKOUG 2011 conference) was the nadir when not a single hand was raised. {Interestingly I asked this at the Slovenian User Group 3 months ago and something like 40% raised their hand – impressive!}.

Friday Philosophy – Whatever Happened to Run Books?

I realised recently that it is many years since I saw what used to be called a Run Book or System Log Book. This was a file – as in a plastic binder – with sheets of paper or printouts in it about a given system. Yes, this was a while back. It would often also have diagrams {occasionally drawn by hand on scraps of paper – so that would be the database ERD then}, hand-written notes and often the printed stuff would have scribbles against it.

{BTW I asked a colleague if he remembered these and when he said he did, what he used to call them – “err, documentation???”. Lol}

Oracle Documentation: The broken links fiasco continues…

So I was just patting myself on the back for finishing my website clean up, then I happened on a few pages with broken links to Oracle documentation. That annoyed me, but I figured I better do a quick scan to see how many broken external links I had. The first attempt was a complete fail because the tool I used clicked all my Google Adsense adverts, making me a DotCom millionaire in about 3 minutes. I wrote to Google and apologised profusely. In my defense, the tool I used was right at the top of the list in the Chrome Web App Store…

Once I got a link checker that didn’t put me at risk of a jail sentence, things got a little more depressing. A very large number of my articles contain broken links to Oracle documentation. As I started looking at links it became apparent that Oracle have used at least 3 main URLs for documentation over the years:

Oracle documentation on a Kindle

I recently bought myself a Kindle – the keyboard 3G version. Keyboard as I know I will want to add notes to things and the 3G version for no better reason than some vague idea of being able to download things when I am away from my WiFi.

So, how about getting Oracle documentation onto it? You can get the oracle manuals as PDF versions (as opposed to HTML) so I knew it was possible and that others have done so before. A quick web search will show a few people have done this already – one of the best posts is by Robin Moffat.

Anyway, this is my take on it.

Lack of Index and Constraint Comments

Something I’ve just reminded myself of is that under Oracle you cannot add a comment on an index or a constraint. You can only add comments on tables, views, materialized views, columns of those object types and a couple of esoteric things like Operators, Editions and Indextypes.

Here is an example of adding comments to tables and columns:
