Intro to Oracle’s Automatic Workload Repository (AWR) 

Paul Boutin’s recent article in Valley Wag discusses Robert Cringley’s declaration of the Death of the Database  that has everyone all excited.  At root is the idea of cloud computing, and the likes of the Google’s of the world storing all of our data, and managing all the dirty messy database storage seemlessly for us.

Yes, I’ll give you that for many applications, and small websites, this will certainly be the future.  Who wants to manage a database for every website.  But for the large clients of Oracle databases, the terrabyte datastores, datawarehouses, Oracle applications, and Financials, the backend datastore will remain a requirement.  This isn’t necessarily because a third party can’t do the job better, or that it wouldn’t make a business sleep better at night leaving the database management to the experts.   Nor is it that security couldn’t be implemented properly, to make the data available only to the business, and invisible to the prying eyes of the DBAs down the line.  No all of those problems are solvable.

The problem is one of handing over the keys to the kingdom.  Take the worldwide GPS system, for example.   Currently Europeans, Russians, and Chinese alike rely on a US built satellite system for GPS service.  Imagine military operations relying on US technology were the US to get into a scuffle with the Russians or the Chinese.  In the end business wants to see their data, if not physically, then confident of where those servers are, and who touches the data, the hardware, the backups etc.

I do agree with Cringley and Boutin that cloud computing will change things, and continue to put pressure on the big database vendors like Oracle, but I don’t think it’ll put them out of business anytime soon.

This month we discuss difficult, and intractible problems, and how sometimes if you can’t find a solution, you might consider changing the problem!

Open Insights 47 - Change the Problem

Intro to PHP + Oracle - Database Journal - Aug 14, 2008

Take a look at  DBA Insider - Useful PL/SQL Packages.

This month’s topic is fixed fee contracts.  We tell a story of a recent business experience, the trouble, the challenge, and the resolution.  Hopefully it’ll help folks out there who are also looking at fixed fee project-based billing, and how to manage scope, and client expectations.

Open Insights 45 - Contractualities

In this May article over at databasejournal.com, we give you an insiders introduction to the goodness that is Perl + Oracle:  Programming, Perl + Oracle.

This piece was published in April over at databasejournal.com.  In it we discuss some of the myriad different index types available to you in Oracle, and try to sift through to the most important ones.

In Oracle you have the option to use the GUI database creation assistant tool, or you can script the process.  We discuss how to do this manually, when you may want to, and hopefully learn a few new things along the way.

When an idea “gains legs”, it begins to have a life of it’s own.  We can see this a lot in the presidential election, but it also applies to consulting.

April’s newsletter was Open Insights 43 - On Prudence.  We talked about risk taking, both the kind we think we like, and the kind that one might call prudent.

Migrating From MySQL To Oracle - Part I

Migrating From MySQL To Oracle - Part II

With MySQL 6.0 out, increasingly we find the full compliment of sophisticated database features in MySQL.  But a lot of the devil is in the details.  Where Oracle has had problems with the sheer size of the codebase, and addressing security vulnerabilities, and other bugs in a timely manner, MySQL has the problem of a mature codebase.  Some of these features are newly available, and if my experiences with replication are any indication, often have hidden gotchas and “features” which are not emphasized in the literature.

The next question on my mind is, how does Oracle’s purchase and now ownership of Innobase impact the above purchase.  It means a direct competitor owns a core component which provides transactional support to your database.  A very good question.

Time will tell, so stay tuned.

The latest newsflash for those who have been sleeping at the wheel is that Oracle is offering support for RHEL called Unbreakable Linux Network.  ULN is basically an up2date or yum network service which will feed you the latest RPMs.  These RPMs have been rebranded for Oracle, but are not a fork or a new distribution.  What you’ll also find as a ULN subscriber is that a little rpm called oracle-validated-configuration is available.  This little package will include lots of Oracle specific tweaks to make installing on Linux that much easier!

For those who’d like to hear all of this from the horses mouth, please read Wim’s Post on Unbreakable Linux.

Oh, and don’t confuse the high-design below with train lines. You’ll use the L or A/C/E trains to get there!

This month’s topic is Reputation Management, or Search Engine Reputation Management.  Related closely to Search Engine Optimization, it is all about building your personal or business brand around your products, services, writings, and social networking memberships.

Archives of the newsletter are available here.  If you like the newsletter, go ahead and subscribe here.  It is published the first of every month.

Oracle’s decided to provide their own support for Linux.  Are they rolling their own distro?  Well actually, no.  They’re doing what CentOS and a few other folks out there are doing.  They’re rebuilding from RedHat’s distro, effectively repackaging their Enterprise Linux distro and in the process testing rigorously, and reporting bugs and issues back, or fixing those themselves.   What’s the deal?

Due to various license requirements with the GPL, RedHat’s distributing Linux must be done as source, so that means third parties can freely recompile that source, effectively using those same tweaks and packaging it up as their own.  Well gee, that’s not fair is it?

I have to admit I’m on the fence on this one.  Honestly folks, the open-source community, of which I consider myself a part of, has been championing Linux, and pitching it to Wall Street,  and big business for over a decade.  So in that vein, hey we’ve done it, and we’re continuing to do it.  That’s great.

It does seem a little odd though that CentOS and Oracle can redistribute RedHat’s sweat and tears.  Or does it?   The logic at CentOS goes if you want support, you can buy RedHat.  If you don’t, you’re free to go ahead and install CentOS as you like.  So despite CentOS being free, Oracle charging a license fee for the support they’re providing, that seems to make sense too.  The truth is that with open-source, we effectively throw IP (intellectual property) to the wind, and let it land wherever it likes.  So if Oracle wishes to capitalize on this, more power to them.

The truth is that the complaints from some camps miss a really important point.  Despite Oracle’s marketing message about making Linux Unbreakable, and Larry’s various trumpeting, Oracle actually does contribute a *LOT* to the Linux community.  Take for example this huge site of open-source projects all by or directly supported by Oracle.   Or another example, Oracle’s rolling Apache into it’s middle tier Fusion product.  Or take another, it’s building of a better driver for PHP.  All of these are very real, very measurable contributions back to the community.

Obviously it’s in Oracle’s interest for open-source technologies to work, as a lot of their customers want that interoperability.  So do I, frankly.  I’ve been working as an independent consultant for over twelve years providing professional services for Oracle and open-source technologies, and making a healthy income, thank you.

I’ll also admit that some of the folks in the Unbreakable Linux team I know personally, and very much respect professionally.  I’ve also met a few of the folks who head up the initiative at Oracle OpenWorld.  They’re all bright, approachable technologists who are as excited about open-source as they are about the Oracle core database product.

I know this may disappoint some of my open-source colleagues, but hey what’d you expect from Mr. “Oracle + Open Source”, hmm?

The article is really an overview of vulnerabilities in the core database product, and how to protect against them.  Part one covers SQL Injection, a way of putting malformed entries into a web page in order to trick the application to run your query.  This can be very dangerous, and is a lot more common than you might think.  Next we cover default passwords, those are obvious right?  Except you’d be surprised how many there are, and how much of a pest they turn out to be.  Next we talk about brute force methods to get into the database, and how affective they are.  And lastly we speak about sneaking information out of the database, and how it can be done.

In part two of the series we cover listener vulnerabilities, privilege escalation which allows some of those underprivileged and default passworded accounts like scott/tiger to become extremely useful.  Lastly we hit on operating system and filesystem vulnerabilities, and how to protect against them.

It’s a short week, so we’ll catch up with you all next week.  Happy Holidays!!

There is a *LOT* of new stuff going on in the Oracle space, what with various new acquisitions, and no one person probably understands it all.

I’ll also say that I ran into an incredible number of new terms which I like to think of as reframing, or looking at things in a new way.  You might also call them buzzwords, so take your pick.  Some you may have heard before, some appear in a new context, and some are old and familiar.  At any rate go ahead,  mull over them and digest:

• information fabric
• information as a service
• service oriented architecture
• what’s the cookbook for doing that?
• oracle by example
• business process management - from order to cash
• extreme transaction processing
• data virtualization
• coherence
• data masking
• it comes baked in or built in
• moving from reactive to proactive
• we can triage their problem
• the democratic, approachable, modern leader
• preintegrated
• comprehensive
• hot pluggable
• go around the corner to find the treasure of an idea
• drinking the open-source koolaid

So long Oracle OpenWorld, see you in 2008!!

OTN has also been podcasting for some time via the OTN Techcasts which I like. We even see some twittering, and meeting with bloggers.  I also see an Oracle user on twitter, and Justin Kestelyn.

Overall I think Oracle’s moves to promote social networking and transparency are good ones.  Perhaps it will be widgets and OpenSocial next, or maybe mashups!!
