Faster, hairy yak, shave, SHAVE!

As previously reported, last week-end’s activities could be summarized as me going to town on a yak herd with a lawnmower. And although the rest of Saturday and this morning haven’t been as fast and furious as Saturday morning, there’s a few more things to report:

HP Cloud starts to Rain!

So HP Cloud is finally yielding for some beta rain since their announcement late Sep.

It started late September when I signed up for private beta testing. They sent me this when I signed up

Thanks for your interest in HP Cloud Services. We will be sure to follow up with you when access becomes available. Since we’re only accepting a limited number of customers for our private beta based on customer profiles, we cannot guarantee that every request will be accepted.

However, we will review your submission and follow-up with you directly.

Two weeks ago, I got invited to join the beta and start testing the platform. Read the rest of this entry . . .

Introducing Dist::Zilla::Plugin::CoalescePod

Yup. Plucking the alpaca’s eyebrows again, I’m afraid…

You see, because of merciless peer pressure, I’ve revived Perl::Achievements. I thought that would keep the wolves at bay, but noooo… Not a hour after the announcement was sent, I got a new feature request. I really should not but… okay, I wanted to do it anyway and if somebody is actually asking for it, why the heck not? Plus, it’ll give me the opportunity to see if my Template::Caribou is up to snuff.

A few hours later, I have a bug report for MooseX::App::Cmd and (after some touch-ups) released the first version of Template::Caribou on CPAN.

And that’s roughly where things get silly…

RIP Flash-based My Oracle Support

The end is nigh for Adobe Flash at My Oracle Support. The first step will happen during this weekend’s planned maintenance of My Oracle support, when all of MOS will be down for 5 hours starting at midnight eastern, Saturday January 28. Once it comes back up, the unadvertised non-Flash supporthtml.oracle.com will come up as a quasi-user acceptance test of the new application, while the flash-based support.oracle.com stays as-is. And once the bugs get worked out (“in the coming months”), the flash-based support.oracle.com will cease to exist and point to the new HTML-based site.

Gearing up for RMOUG Training Days 2012

The 2012 edition of RMOUG Training Days in Denver less than a month away, running February 15 and 16 at the Colorado Convention Center in Denver. Although it’s only two days, there’s a lot of technical content there, and a refreshing reduction in marketing-oriented presentations from “product managers”. It’s not too late to register, and it’s a pretty nice excuse to get to the Rockies in ski season. I’ll be doing two presentations, and am polishing up whitepapers and presentations for the submission deadline tomorrow:

They’re right after each other in the grid, but I do get a short break for the dedicated exhibit hall time and paid vendor presentations (yes there are still a few; they have to pay the bills somehow).

Replication stopped with duplicate entry upon starting up of MySQL from cold backup

A few days ago, we faced a Duplicate entry problem in the mysqld server on one of our customer’s slave after cold backup. We do regular data sync checks for all of our customer’s as daily reports and check for data discrepancies between master and slave server’s, if any got picked up by our checks to investigate, and there was no issues for the particular server and with the report. When checked the entry details, there is a row with the same data in the table that was mentioned by Slave status Last_error entity.

Quick check on the error log showed that the slave was started after cold back’s and immediately stopped with a duplicate entry error and the mysqld server version is 5.0.77-log Source distribution. From the analysis of the below statements, we found that the slave SQL thread was stopped with the error at a position backwards than the SQL thread initialized after cold backup’s.

R12.2 online patching – What are the hidden costs?

One of the hot topics at the UKOUG 2011 Technology and E-Business Suite Conference last December was the upcoming release of Oracle e-Business Suite R12.2. The new release will bring us lots of new features, usability improvements and new versions of technology stack components (Oracle Database 11g R2 and Oracle Fusion Middleware 11g R1 as the application server), but the most important and impressive new feature of course will be online patching. Online patching is supposed to change the game completely. All owners of E-Business Suite environments know that patching requires downtime. Although it can be reduced with various techniques (e.g. staged APPL_TOP), some downtime is still required to apply a number of changes. Online patching will not eliminate downtime completely, but will reduce it significantly by using  “Edition Based Redefinition” (EBR) at the database level and using a secondary applications file system for online patching. In fact, all patching activity will be an online operation; downtime will be required only to switch from one version to another. Read the rest of this entry . . .
