I’m writing this (unusual) post as I am a long time Gmail user and recently I’ve seen plenty of people & articles complain about the Gmail’s new compose window (the one that shows up as a small hovering window in the bottom right of your screen):
The top google hits so far only return tips to disable the new editor completely, but I want to use the new one, just in a bigger window! There is a very easy workaround for that – and there’s no need to switch back to the old compose mode at all!
If you are using your mouse, then just:
I have fixed most of the bugs that showed up during the Snapper launch party session and uploaded the new version (v4.02) of Snapper here:
I have also uploaded the launch party hacking session video to enkitec.tv:
I have not updated the snapper documentation yet, but here are the main improvements:
I am lazy, therefore if I can type less, I will type less.
Often people are surprised to see that Oracle supports the ANSI DATE and TIMESTAMP syntax in the SQL code, which allows me to shorten the lengthy TO_DATE( …. , ‘YYYY-MM-DD HH24:MI:SS’) syntax a bit. You can just type this if you want to compare some field to a date (day precision):
SQL> SELECT COUNT(*) FROM dba_objects WHERE created > DATE'2012-12-01'; COUNT(*) ---------- 0 SQL> SELECT COUNT(*) FROM dba_objects WHERE created > DATE'2012-01-01'; COUNT(*) ---------- 804
This way you can always use the standard date format regardless of any NLS settings that may say otherwise.
Ok, I’ve wanted to write this blog entry for a long time – and now it’s time!
Most of my blog readers (thank you!) are performance-minded computer enthusiasts, who care about efficiency and optimization. You’ve been tuning SQL execution plans, instance and OS configuration so that your sessions would achieve the same results with less work and also with less waiting!
You probably know to appreciate why asynchronous I/O must be enabled for busy modern databases, so that your database sessions can do I/O (talk to the storage) without actually having to wait for the I/O operations to complete! You can increase the processing throughput, by not submitting every single I/O separately and waiting for it to complete, before being able to process the results and submit the next one. Asynchronous I/O is a crucial thing for good performance.
First, a reminder – my Advanced Oracle Troubleshooting v2.0 online seminar starts next week already. Last chance to sign up, I can accept registrations until Sunday :-)
I won’t do another AOT seminar before Oct (or Nov) this year. More details and sign-up here:
I have rescheduled my Advanced SQL Tuning and Partitioning & Parallel Execution for Performance seminars too. I will do them in September/October. Unfortunately I’m too busy right now to do them before the summer.
And that’s all the travel I will do this year…
I’ll soon announce the 2nd EsSN virtual conference too ;-)
Free online stuff:
Perhaps in a month or so I will do another hacking session (I’ll plan 2 hours this time, 1 hour isn’t nearly enough for going deep). The topic will probably be about low-level details of SQL plan execution internals… stay tuned!
People talk about the Oracle SQL Developer 3 being out, which is cool, but I have something even cooler for you today ;-)
I finally figured out how to convert my screen-recordings to uploadable videos, so that the text wouldn’t get unreadable and blurry.
So, here’s the first video, about a tool called MOATS, which we have built together with fellow OakTable Network member and a PL/SQL wizard Adrian Billington (of oracle-developer.net).
Here’s the video, it’s under 3 minutes long. Play the video in full screen for best results (and if it’s too slow loading, change it to lower resolution from HD mode):
Check it out and if you like MOATS, you can download it from Adrian’s website site (current version 1.05) and make sure you read the README.txt file in the zip!
Also thanks to Randolf Geist for finding and fixing some bugs in our alpha code… Note that MOATS is still kind of beta right now…
P.S. I will post my ORA-4031 and shared pool hacking video real soon now, too! :-)
P.P.S. Have you already figured out how it works?! ;-)
Update: Now you can suggest new features and improvement requests here:
A lot of people have asked me whether there’s some sort of index or “table of contents” of my TPT scripts (there’s over 500 scripts in the tpt_public.zip file – http://tech.e2sn.com/oracle-scripts-and-tools )
I have planned to create such index for years, but never got to it. I probably never will :) So a good way to extract the descriptions of some scripts is this (run the command in the directory where you extracted my scripts to):
And this time we have audio !!! (Wow!)
Following the huge success of my last hacking session, planned while drinking beer at Graham Woods OOW pre-party and delivered from Miracle’s massive Oracle Closed World event in Thirsty Bear (between drinking beers), I’m announcing another hacking session:
What: Using Session Snapper for flexible Oracle Performance Troubleshooting
When: Wednesday 27th Oct 9:00-10:00 AM PDT (US West coast / California time). Check what’s this in your time zone here
Where: Internet! -> Sign up here: http://tech.e2sn.com/secret
You’ll need to register fast and be “there” on time as my current GotoWebinar account only allow 100 attendees to log on… last time over 100 people signed up, but “luckily” less actually showed up, so nobody got left outside!
BTW, I have figured out what went wrong with audio last time and caused my voice in the end of presentation disappear). A program, which I accidentally launched via a keyboard shortcut, grabbed my Mic input to itself, so gotowebinar’s app couldn’t access it anymore.
See you soon!
I’ve been tracking my business travel with Tripit.com‘s awesome service for about 2 years now.
After getting back from my Tallinn->Helsinki->New York->Detroit->New York->San Francisco->New York->Helsinki->Tallinn trip yesterday, Tripit reported that I have flown 1 007 509 km during my business trips (American readers, that’s about 42 miles ;)
Check yourself below :)
Tripit says I’ve visited 71 different cities in 27 countries within the last two years.
Here’s the map of places where I’ve visited my clients, done training or spoken at conferences:
Actually there’s probably couple of more cities where I’ve been in the last two years, for some reason Tripit doesn’t recognize my trip to Melbourne (but it does show the visit to Sydney which I did during the same trip).
Anyway, the conclusion here is that I think I’ve done enough flying for now. Now I plan to stay at home for a loooong time (I mean at least 3-4, maybe even 5 weeks in a row!!! ;)
But seriously, what I’ve decided is that:
Ok, enough of self-promotion and advertising, back to work ;-)
P.S. I will publish my online seminar schedule “very soon now”!!!
P.P.S. I’m not affiliated with Tripit.com by any means business-wise, but if you travel frequently, then I recommend you to check out their awesome service (and iPhone app). The basic version is free, but I just decided to upgrade to Pro after couple of years of using it!
