The weather is changing, clocks are being adjusted, and the changes at the technological front are as usual rapid, frequent, and over-whelming. Keeping up with such rapid-fire changes is a project in itself. In the database triangle of Oracle, SQL Server, and MySQL, patches, updates, features, tricks, and tips are booming, and so is this Log Buffer Edition.
Many readers of these BLOG posts are seasoned attendees/presenters at this IOUG/OAUG/Quest collaborative event held every spring. User group events are one of the best stomping ground for hungry IT specialists, thirsting for news on late-breaking solutions and more traditional technologies.
In my previous post, I described how to install Oracle VM and Oracle VM Manager on the same sandbox. However, to start playing with Oracle VM v3 you need to configure some storage to be used for new VM hosts. The problem is that Oracle states that you should allocate a full HDD for VM host storage. If you have just one HDD in your system, then you are in trouble since part of it is already occupied by the Dom0 host.
By now, I have a few Dist::Zilla plugins interacting with the distribution’s changelog. Each time I get the changelog, I parse it into a CPAN::Changes object, do something to it, and save it again. It’s actually not even as hard as it sounds. Have a look.
Just a quick heads up to the ODA customers — there is a critical patch 184.108.40.206.1 out that is applied on top of ODA patch bundle 220.127.116.11.0. This patch has an important fix for a bug causing ODA servers to shutdown in some situations when an ASM disk is lost.
The method of disabling triggers requires Oracle 18.104.22.168+ or 10.2.0.5+, plus execute permissions on sys.dbms_xstream_gg. Since it’s a call to an XStream package, it may also require a XStream license. So if I haven’t scared you away yet, here’s a quick testcase:
The biggest objection to Oracle Database Appliance (ODA) we hear from customers is about 4TB usable space limit (tripple mirrored 12TB of raw storage). I think most of the times this is more a perceived barrier rather than objective — more along the lines of being afraid to hit the limit if the system grows a lot. Nevertheless, Oracle has been always listening customers’ concerns when it comes to purchasing barriers. Of course, this time is no exception.
Stumbled upon this Dell’s article from 2001, So what do we see 10 years later? Singe device, no fuss, everything pre-configured, Oracle RAC, simplified operations — dream of 2001 finally coming true?
Today I got an email reminder that the Metacpan logos are all in and that the voting booths are open, and will be so until Friday the 30th of March 2012, 23:00:00 UTC.
There is so much to learn out there. So much to accomplish and so much to devour technically. It can be daunting and overwhelming to have so much in one’s plate, and that is why this Log Buffer Edition has culled some top notch blog posts for you in Log buffer #264.
