It was a real early start for this one, as I flew up from London on the day of the conference. I was a little bit nervous about being late as I was landing in Glasgow at 09:50 and my presentation was meant to start at 11:30. I’ve flown from T5 before, but I had not [...]

I’ve been meaning to write this one up for ages, and having just seen Dave Burnham’s interesting presentation on this, I’ve finally gotten round to it. I’ve upgraded a few RAC clusters to 10.2.0.4 now. These are clusters that have been running with high levels of stability for a couple of years at 10gR2. I had [...]

I got a question after my “What ASM Can Do For You” presentation yesterday regarding where I got the images that are in the presentation and why there was no attribution. An example below is one I have used in the past when talking about myths: The images I use are all micro stock photos. These [...]

Thankfully I had my excellent colleague, Arjan Van Der Meer, to drive me up to the heritage motor center on a bright sunny day. It was quite a poor turnout really, down to 43. Probably the lowest RAC & HA SIG turnout, and much less than the last time we were at this venue. I did not [...]

I thought I would have a posting to try and summarise my experiences at this years Oracle OpenWorld. First off I had a brilliant time, I think it was better than I was expecting by a long way. I really, really liked San Francisco. I don’t think I’m a great traveller but I thought the [...]

Automatic Storage Management - Frits Hoogland Fantastic crowd for 09:00am the day after the big party. The room is jammed packed. Frits comes across as a very confident speaker. This was one of the most technical in depth presentations I have seen the whole week at Openworld. It feels quite strange after all the generic overviews. not all [...]

A successful 11g installation - Plamen Zyumbyulev & Phil Newlan First part of the presentation is from Plamen trying to get to a dynamically configurable infrastracture moving to a service approach (oracle services) effective automatic workload management with NO single point of failure. need centralised monitoring and management. running linux x86-64 with blades, though he said privately that he [...]

Well I might as well give it a go live blogging the Larry Ellison Keynote. It’s being broadcast on the web, so I’m not sure how many will read it live, but what the hell. If nothing else it should lead to some humorous spelling mistakes. First off, I LOVE being a blogger. I skipped past [...]

Current Trends in Real World Database Performance - Andrew Holdsworth This was a run through of issues seen by Andrew’s group in the past year (10 months to be exact) Real World Performance Fundamentals Things are harder with increasing dataset sizes, and transaction rates. Increasingly rigorous targets. Ever increasing CPU power and lower memory costs. The bigger the database [...]

I seem to be spending a small fortune on taxi journeys. Twice now the taxi driver has actually asked me for directions to the destination, I could not believe one of the guys did not know where the Moscone Center was! I would not want to not know where I was going in SF. Active-Active Datacenters - [...]

6 Questions being answered from lots sent in via email top features of Oracle 11g performance secure files - similar performance graph to juan laioza compression demonstration on advanced compression table with 5.5M rows using 200,000 blocks. compared with a table using advanced compression is 55,000 blocks almost x4 less space also is showing graphical explain plan monitoring via grid [...]

Next Generation Performance & Scalability - Juan Loaiza This presentation was really a run through of 11g features. I was expecting a little bit more about what was coming rather than a review of current 11g features, this talk could have been delivered last year, I think or renamed “this generation” rather than next! Oracle are being [...]

I watched the Charles Phillips Keynote from the OTN lounge - you can take it from me that it ain’t as comfy as the “Club Oracle Gold Lounge”. Oracle now owns the full stack. Best of breed in all areas. Oracle Beehive - collaboration suite integrated, blogs, wiki, email, chat, callendars. oracle db backend also uses fusion [...]

I had a slow start Sunday. Had a little look around San Francisco first before going to register. The closer to the Moscone I got the more people with OpenWorld tags round their neck there was. The Apple store was crammed with delegates, made the mistake of looking at a 24″ iMac. Those screens look [...]

Well, It’s 02:26 in San Francisco, but try telling that to my body. I’ve had a couple hours sleep and now it thinks it’s morning. Gah. It’ll be an interesting day trying to keep awake if I can’t get any more sleep. I did not make it to register on the Saturday - too excited to [...]

Even the lamposts are in on the act: . The media has gone into full speculation overdrive, but I’m thinking the the register don’t have much to go on with this one, but clearly it is going to be an interesting week, and thankfully i’m on the right side of the pond. It is weird though seeing my [...]

Quite a poor turnout I thought, in a rainy grey Slough. Here are some quick contemporaneous notes I took during the day, a little bit on the short side I’m afraid! Auditing Recoverability - Tony Hasler Audit//health check your backups prohibit deletion of archived logs that have not been backed up multiple times. recovery options: drop & recreate tablespace flashback recovery from [...]

A short posting highlighting some UKOUG events coming up in the near future. First off, I’m speaking at the UNIX SIG on Thursday 11th in Slough. The agenda has been online for a while and I’m doing an hour long presentation on ASM. Next up for me will be another ASM presentation at the RAC & [...]

You all are probably aware that over the weekend of 23rd August, the Oracle Forums underwent an upgrade. I would not bother clicking on the link though, chances are you will end up seeing something like this: I would not say the upgrade has gone well. The above was taken on Wednesday at 09:30am BST, some [...]

I used to use mind maps while I was still at school in the early 90’s, yeah last century. I found them useful then, but I seem to have really fallen out of the habit of using them. I do think they can be useful in gaining an overall picture of a subject or topic. I [...]
