One of the items on the to-do list for Dancer 2 is to verify that most of the plugins already written for Dancer 1 will still work for Dancer 2. Well, I thought, that’s just like doing smoke testing for a small subset of Perl modules. How hard can it be? Lets get cracking…
We came across a Couchbase bug during a rebalance while upgrading online to 1.8.1 from 1.8.0. Via the UI, we upgraded our first node, re-added it to the cluster, and then set the rebalance off. It was progressing fine, then stopped around 48% for all nodes. The tap and disk queues were quiet and there…
If you regularly manage enormous data sets, you’ve probably heard about Tumblr’s exciting new toolkit called Jetpants, which automates common processes for MySQL data management, most notably in the area of rebalancing shards for more efficient scaling. In evaluating and using Jetpants in various environments, we identified some interesting installation and usage gotchas, and we’ve…
Every time I have had the pleasure of attending Oracle Open World, I have discovered a plethora of technical heavy-weights from all over the world in attendance. I enjoy meeting and shmoozing with these people almost as much as absorbing the technical content of the show itself. Many of my Pythian colleagues are presenting at OOW12 and thereby making this fine company AND themselves more renowned in the Oracle tech arena:
There’s a known bug, 7306820 “ORA-7445 [krhahw] / ORA-27090 during file header read. Instances may crash, but this bug is fixed in 188.8.131.52, and this database is running 184.108.40.206. And on top of that, it’s an Exadata system, so I/O to storage servers goes over the InfiniBand network rather than using async I/O (AIO) calls.
I was thumbing through the photos in my iPhone from my Melbourne trip of August, where I went to present two sessions on Exadata in Insync12 from Pythian. I spent couple of hours on first and last day in sight-seeing or should I say my iPhone did the sight-seeing, and I nursed him. As I was going through the photos, I realized I was kind of watching those places first time. There were many things which were present in the photos, but I never saw them with my own eyes while walking or traveling in the trams or cabs.
Thank you to all who attended our Open House last night to help us celebrate Pythian’s 15th Anniversary. It was a great night! Thank you to all those who helped make it happen. Check out a few highlights from the evening.
With the summer approaching in Australia and Winter making inroads in Canada, the contrasts are also vivid in the blog posts of Oracle, SQL Server and MySQL. Relishing this distinguished medley, Log Buffer Edition is blossoming with new blog posts in Log Buffer #286.
Today, I had some bit of fun and created a micro-web service as a one-liner. But then I thought that using almost 70 characters for a web service was awfully long-winded. Surely there was a way to make our Dancer more efficient. But how? How about… by getting a MC involved?
If you remember, I posted some tips about troubleshooting Link Server issue for Oracle earlier. Today I will be posting one more tip to the list aka extending Troubleshooting Oracle Link Server.
