During my presentation at the TOUG meeting, I mentioned that when using 11g’s enhanced security settings or, at least, the audit setting, you risk the unlimited growth of the SYSTEM. Mohamed El-Shafie from Oracle quickly noticed that there is no auto-purge. I promised to have another look at the maintenance tasks in 11g to confirm that, and indeed, the audit trail is not purged automatically when auditing is enabled by default. Here is a quick remedy — scheduling an audit trail maintenance job.
This is what I found in the APEX documentation that comes with Oracle 11g, in the chapter describing building a very simple application…Making sure the database instance couldn’t potentially use an index in DEPARTMENT_ID column? Why on earth would you teach novice APEX developers such a horrible practice? To me, it’s one more confirmation that Oracle can do an excellent RDBMS, but when it comes to database applications development . . .
Small local user group meetings have their own beauty because of the special intimate atmosphere. We expected somewhat higher attendance but it seems that people were already in the holiday mode. The presentation itself went very well and I liked my pace since I didn’t have any time pressure. I’ve done this presentation before in 45 minutes and this time it took slightly more than an hour but I was able to spend additional time on few more complex topics and explain the underlying concepts making sure we all are on the same page. I also enjoyed the questions during the presentation — always a pleasure to know which parts are more interesting to the audience and questions is one of the best indicators. Another one is when people take notes. All in all — it was a very encouraging hour. Thanks to every one who attended!
Today I’m doing a presentation at the Toronto Oracle User Group meeting. It’ll be my first time there and I’m really looking forward to it. My session is called Oracle 11g New Features Out of the Box. It went pretty well at Collaborate 08 and I think it will be the right audience at the TOUG meeting.
In case you are attending Oracle Open World 2008, the biggest Oracle conference in the world, and interested in either (or both) MySQL or Oracle Enterprise Manager Extensibility — I posted a proposal for a new presentation: Extending Oracle Enterprise Manager by Example — Creating MySQL Management Plug-In
Back in April I was at COLLABORATE 08 and delivered a presentation on 11g — Oracle 11g New Features Out of the Box, including Oracle 11g ASM features. The first ASM slide was about diskgroup compatibility, and I have a bit more to share than I said back then.
It’s been a while since the MySQL Management Plug-in 0.42 was released. Since then, I quietly updated it to version 1.0. The changes were very few; the biggest news was that the plug-in was certified by Oracle and added to OTN Oracle 10g Grid Control Extensions Exchange. Version 1.1 turned out to be a major rewrite for the Perl collection scripts and the net result is that compatibility across platforms is greatly improved. I have successfully tested the new version on Linux and Windows Agent hosts. So what’s new in version 1.1 compared to 0.42? Find out here.
I just wanted to make a quick note that Oracle Mix organized an interesting hybrid between call for papers and abstract judging. Anyone registered at Oracle Mix can propose a session abstract to present themselves or as an idea for others. Everyone can give their votes to the proposed sessions. At the end of the voting deadline (25th of June) Oracle will select the top sessions to be included in the Oracle Open World schedule.
The latest news — there is a new web site — ashmasters.com. This is the place where you can leave your comments and questions about ASH and ASHMON. Wondering how you can query ASH data? There are some ready to use queries. Have a cool idea how to use ASH and query ASH data? Share it there and have it added to the ASH Masters queries toolkit.
Here is the question that was posted on OTN Forum Grid Control Extensibility. My first reaction was — how stupid one should be to post such absolutely irrelevant question in that forum? I was even more surprised that someone actually tried to provide a sensible response…
