A Question from OTN Forum

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…

Alex Gorbachev at COLLABORATE 08

I guess I have only one and a half posts about COLLABORATE 08 this year. It’s a bit unfortunate that I couldn’t make the whole conference, but only last day-and-a-half. In addition, I’ve been speaking at the two lasts slots of the conference so it’s been quite busy for me. I hope this one long blog post will be accepted in place of several smaller ones.

Arrived at COLLABORATE 08

I’m at Collaborate 08 in Denver right now.My presentation, Oracle 11g New Features Out of the Box, was originally scheduled on Thursday at 9:45 AM but due to participation in the speaker panel ,”To RAC or Not To RAC: What’s Best for HA?”, it was rescheduled to today, Wednesday, at 4:30 PM. I’m off to the Carol Dacko’s presentation about DBMS_XPLAN now and looking forward to show up at the RAC SIG Birds of a Feather later today. Stay tuned – more to come…

MySQL Plug-in 0.42 for Oracle Grid Control: First Beta Released

has finally happened! The first public release of the MySQL plug-in for Oracle Enterprise Manager 10g Grid Control is out. In the last few months, more and more people showed interest in the potential plug-in, and even few guys from Oracle contacted me independently of each other with their own reasons to have a MySQL plug-in available. This interest accelerated the fermentation of thoughts in my brain, and I got down to work. Pythian generously sponsored my development time. Here are the details. The first release version is 0.42 because that’s obviously the perfect number to start something good.

Oracle ASM 11g: Does the ASMCMD cp Command Really Work?

Since the introduction of ASM in Oracle 10g Release 1, every ASM administrator has been dreaming of a simple command line tool to copy files between ASM diskgroups and other filesystems. Oracle ASM 10g Release 2 added the handy asmcmd utility, but even though everyone expected a copy command there, it had not been implemented. While working on a Collaborate 08 presentation on Oracle 11g new features out-of-the-box, I was verifying new commands in Oracle ASM 11g’s asmcmd utility. It turned our that copying files from or to ASM is still a problem.

How To Identify the Database Links of a Failed Refresh Job

I have a client with refreshes scheduled using MV refresh groups, and it took me a while to recall the view name, asking around and RTFM’ing. Since this situation comes up regularly, I wrapped up a quick script that parses job content, takes in account MV refresh groups, and outputs the database link(s) involved. I think it could be useful to few others so here it goes.

Is Summer Canceled in Ottawa This Year?

If you are a regular reader of this blog, you know that I was at the Hotsos Symposium 2008 this year. You might not know that I also had a chance to take few days off and spend 1+ week vacation in Texas after the symposium — enjoyed the sun and warm weather. My family liked that even more than I did. Unfortunately, when I was back home last weekend, I discovered pretty unpleasant view from my windows…

Hotsos Symposium 2008 — Still On

The symposia is still ongoing and my head is slowly filling up — relieved from my presentation, finally, I’m able to focus on others’ sessions. I attended Wolfgang Breitling’s presentation on “Active Statistics”. He provided a lot of insights into statistics gathering options and emphasized lots of new features in 11g. Have a look at my post to read about some of the other great presentations I attended.
