ROWID equivalent in Microsoft SQL*Server

Thu, 2013-10-31 07:07
The last few months I've been having to work with Microsoft SQL*Server 2008 R2 for a project I'm on.  I'm not finding it fun for a variety of reasons, including that it doesn't seem as capable as I recall Oracle being and that the source data I'm having to work with is very, very dirty. One of the complicating factors is often there will be exactly, or almost exactly, duplicate rows when each Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0

Tablet PCs - Why so pricey?

Is touch screen really expensive to do or something. I've been tossing around the idea of getting a tablet PC to stick OneNote on to use for note taking, reading documents and some web surfing (including Gmail) via WiFi. I'm having to attend a lot of meetings/briefings where the ability to take notes and link them to documents and web pages would be incredibly useful.Looking around the web the Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0

Oracle aims to secure future of Sparc, Solaris and Sun hardware

Thu, 2010-02-04 11:09
Interesting article on ComputerWeekly.com about how Oracle are looking to secure the future of Sparc, Solaris and Sun Hardware. They don't mention it but I wouldn't be surprised if we see 'Database as an Appliance' coming soon with Oracle Database running on Sun Hardware with management taken out of the hands of the local DBA and automated or made accessible only to Oracle themselves.

Oracle to buy Sun

Mon, 2009-04-20 09:14
Oracle announced today that they will be buying Sun Microsystems. Their plan is to produce 'pre-integrated' systems where everything from the bare metal, silicon and spinning rust up to the application front end is from themselves. The idea is that customers will save money on systems integration costs but reliability will go up.Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com1

Ada Lovelace Day

Tue, 2009-03-24 07:23
Apparently today is Ada Lovelace Day. Ada Lovelace (aka Augusta Ada King, Countess of Lovelace) is widely recognised as the first computer programmer. The daughter of Lord Byron, she was encouraged away from her father's dissolute lifestyle by her mother, who encouraged her interest in mathematics. Ada excelled at mathematics and became a friend for Charles Babbage.When Babbage created his Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0

New Blog - Stephen's SAP Blog

Wed, 2009-03-04 07:21
As I'm now beginning to work on SAP I've started a blog about it, mostly just somewhere to make notes about interesting/useful things I come across. If it also helps anyone else then great but if it doesn't then no worries.One of the things I have noticed, comparing Oracle with SAP, is that whilst for Oracle you can find online free resources at pretty much any level (both official Oracle sites Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com1

Old tech you'd like to see updated and rereleased

Mon, 2008-12-01 02:33
Note an Oracle post, but I know a lot of DBAs and into tech as well.Yesterday I found my old Psion3 mx (which I used before having to switch to Palm handhelds due to work). I had a play and was reminded why I liked it so much. The key advantage it had, and still has over many more modern devices, is the size. It's small enough to fit in a suit jacket or coat pocket whilst being large enough toStephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0

Dataguard, documentation/scripts for non-DBAs during failover

Wed, 2007-05-23 06:37
We're looking at implementing Dataguard as part of an implementation of Documentum (a document management system from EMC) and I have been asked to look at producing documentation and scripts for non-DBA users to use during a failover. The actual failover of the database itself will be handled by our DBAs, this is for the sys admins, network admins, application admins &c who may need to do Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com1

Preventing record deletion

This entry is partly an aide memoire for me, partly to try to get something that has been keeping me awake for the past hour or so out of my brain so I can sleep and partly in the hope that someone can suggest a way forward.A quick bit of background.

Remote automated install of Oracle 10g client

We have a situation where we need to rationalise the range of installed Oracle clients (i.e. the bit that sits between the app and the network stack) we have installed. We currently have versions from 7.x through to 10.2 installed accross approximately 12,000 desktops (accross various locations in an area of around 26 square miles) running various apps on Windows versions from NT4 to XP (mostly Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com1

How people find this blog

Thu, 2006-11-23 02:38
I was just looking at my stat counter analysis for this blog, it's usually a good way to find out if anyone has linked to me. From the results it looks like the vast majority of people (around 97%) find this blog through a search engine, virtually all (over 99%) through Google. Most common search strings are or include "ORA-07445", "opmnctl failed to start process" and "ORA-01031".Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0

Never volunteer

Tue, 2006-11-21 03:29
During his presentation on "Inside RAC" Julian Dyke appeared to suffer laptop difficulties so asked for 4 volunteers to assist in a demonstration. Being the helpful soul (i.e. idiot) that I am, I volunteered. Mr Dyke did seem remarkably wellprepared in terms of props, almost as if he had been expecting his laptop to have problems :-)!Photographic evidence (courtesy of Connor McDonald) can be Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com1

Histogram problems

A question just appeared on the Oracle-L mailing list about whether there are any issues with using histograms. I've seen a number of presentations over the last couple of years that have warned about issues where you have histograms on highly skewed data and use bind variable (or have cursor_sharing=force, which synthesises bind variable from literals in queries), so I responded:On 19/11/06, A Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0

Today was the first day of the United Kingdom Oracle User Group 2006 conference. The day itself was pretty good, lots of good talks (more on that later), but I ran into a couple of issues in the evening.

Random training related thought

Mon, 2006-08-28 15:50
A thought just crossed my mind. I wonder if there is a market for short (one day) task oriented training for the sort of things that aren't normally covered in general courses.For example I'm aware that there are training courses that mention standby databases and certainly there are courses that cover RMAN, at least for basic backup and recovery. I'm not aware of any that actually take you Stephen Boothhttps://plus.google.com/107526053475064059763noreply@blogger.com0
