Nov 2: 11.1.0.7 Fun

Well, I make that about 4 weeks since I installed 11.1.0.7 on my laptop on, yes, Vista but the weeks have flown by and I've only had a very quick play with it.

It was released along with another few ports that I was surprised to see appear so quickly, specifically AIX. As I'm working at an AIX site at the moment, I'm used to the long wait for 'Tier 2' ports to appear. It's usually about 6 months minimum. In a fit of wild speculation based on no solid information, I'd venture that the Linux port was ready long ago but was held back for Openworld as part of the Exadata announcement, which meant that the other porting teams caught up and were able to release soon after Openworld. As I said, wild speculation, but most of the Exadata blog posts I've seen in the past month seem to be similarly uninformed which is all the more surprising when there are plenty of white papers online. Frankly, you'd think if someone sets themself up as an industry analyst, they would take the time to read public information before they start spouting opinions. I suppose that's probably why I'll never make it as an industry analyst.

So what's in 11g that would have given some of the Exadata game away if it had been released before Openworld? Here are a few little fun details.

Because of the OEM performance presentations and the course, one of the first things I do is take a look at DB Control for any new update (and I need to remember to respond to Noon's post one day soon). At the bottom of the main Performance Page for the instance in the 11g screens is a tabbed section that includes an I/O tab which is one of the most noticeable improvements in 11g.



What may or may not be obvious from a small graphic is that the first of the I/O types listed in the key in the right hand side is 'Smart Scan', but I don't expect I'll be seeing that appearing in graphs on my laptop any time soon ;-)

While I was at it, I thought I'd see if there were any Exadata-related parameters or timed events.

SYS@TEST11> select name, value from v$parameter
  2  where name like '%cell%';

NAME
----------------------------------------
VALUE
--------------------------------------------------------------------------------
cell_partition_large_extents
DEFAULT
cell_offload_processing

cell_offload_parameters

cell_offload_compaction

cell_offload_plan_display
AUTO

SYS@TEST11> select name, wait_class from v$event_name where name like '%cell%';

NAME                                     WAIT_CLASS
---------------------------------------- --------------------
cell smart table scan                    User I/O
cell smart index scan                    User I/O

cell smart restore from backup           System I/O
cell single block physical read          User I/O
cell multiblock physical read            User I/O
Streams miscellaneous event              Other

Just a bit of fun, but nowhere near as much fun as Real Time SQL Monitoring. Now *that's* a feature worth upgrading for!

Oct 26: UKOUG 2008

Wow. Three weeks since I last posted. I'm not sure if it's been that long before. There are a couple of posts that I have in mind, including some initial fun impressions of 11.1.0.7, which I installed a couple of weeks ago but, for now. Here's my current best guess as to which presentations I'll be attending in the first week of December.

Oct 4: Belgium Seminar Cancelled

Unfortunately, the two day performance course I was due to be teaching in Belgium in a couple of weeks has been cancelled. It also means that I won't be getting to see the DUDE as soon as I thought :-(

Oct 4: C. J. Date in Edinburgh

With the help of Oracle as sponsors, Peter Robson has organised a new seminar with Chris Date in Edinburgh on 10-12th of November. The format of "A Relational Approach to SQL" will be two days of tutorial-like presentation from Date, followed by a Wednesday morning of discussion and debate. It sounds fascinating to me but unfortunately I can't make those dates. Oh, and the cost for this opportunity? Fifty quid, to cover refreshments! That sounds like an opportunity that's too good to pass up if you're interested in the subject so I suspect that places will disappear quickly.

More information here and here.

Oct 4: OOW 2008 Presentations Update

Well, I'm very pleased to see that non-attendees can access the presentations now, using this approach. I had confirmation from someone at Oracle that they wouldn't be accessible so either their information was wrong or there's been a change of heart.

For example, here is Juan Loaiza's Exadata presentation from Thursday.

Links in Comments

It's a minor source of frustration to me that you can't just paste a Hypertext link into the comments form here but, should you ever want to include a link, all you need to do is use the BBCode format, as mentioned below the comment form.

Here is a link to the relevant part of the document that explains how.
