I just arrived and right in time for the Oracle ACE Directors’ briefing that will run for the whole days of Friday. This is a super secret meeting where Oracle’s super secret plans are shared. The ACE Director’s briefing is where Oracle shares the roadmap of its products — some of it is long term strategy and some is about the upcoming releases.
I got an error message trying to login at oracle.com saying my account was locked. There was a simple solution for this, all you need to do is to use “Forgot password” functionality – this will reset your password and unblock the account.
I’ve just wrote few bits about learning a new technology and after skimming through my Google Reader, I noticed a great post by Gwen Shapira — Deliberate Practice. That’s reminded me about another aspect of learning that I didn’t mention — learning is a continuous process.
For one of our customers, I’ve recently reviewed the strategy of migration from single-byte encoding to variable length multi-byte UTF8 (AL32UTF8 encoding in Oracle naming standards). These type of projects are coming up again and again so I think it must be common for many of you. Thus, this bit might be useful. This is the PL/SQL block I came up with
was recently installing one APEX application and needed to upload a bunch of images. APEX was configured to use EGP (Embedded PL/SQL Gateway) so traditional options were to configure FTP or WebDAV but I’d rather not open these services on production environment. Our resident APEX expert pointed me to the installation process and suggested there is a simple way to do that using a single PL/SQL call. It turned out that it was more than a single PL/SQL call involved but nothing too difficult. What you need is to create the hierarchy of files and directories that you want to upload (images or not – doesn’t matter). Then you create an XML file imagelist.xml listing required directories and files to upload. Here is the example:
This is just a short blog post to spread the word about the upcoming webinar organized by Embarcadero with fellow member of OakTable Network — Jonathan Lewis and Kyle Hailey — Ultimate SQL Tune-off.
NoCOUG Spring Conference 2010 is in just 10 days, I’ll be doing my two hour long presentation — Demystifying Oracle RAC Workload Management. If it’s your local conference, I hope you can attend and say hello. You might also want to download the whitepaper that I put together few years ago for Hotsos Symposium — Oracle RAC Workload Management.
I want to post the slides of the two presentations I did. My first presentation was a double slot session about Oracle Clusterware internals. My second presentation was about how we designed and run 1TB MySQL database in high availability setup.
I’m in Denmark these days at the wonderful Oracle conference organized by Miracle A/S — Miracle OpenWorld 2010. Opening session was something special this year, the opening was rounded up with a new film production demo from We Do Not Use TV Studio. Time to grab a bite and get ready to my dual-slot presentation — Under the Hood of Oracle Clusterware which is the very first presentation of today. More to come — stay tuned.
I’m excited to announce that Gwen Shapira has started with Pythian this week. :) Chen is no stranger here and many of my colleagues already know her and were in touch — she just naturally fits in.
