Welcome to the 145th edition of Log Buffer, the weekly review of database blogs.

MySQL

Since MySQL was surely the belle of the bloggers’ ball this week—why, everyone was talking—let’s begin with it.

Baron Schwartz started something with his post examining why MySQL might not benefit from having a mother ship. Dean Ellis of niflheim responded, arguing that everyone needs the MySQL mothership. And that got Sheeri’s Cabral’s attention—she took the middle path in her …

This edition of Log Buffer is my first article on the Pythian Blog. It seems appropriate that, as I start a new chapter of my life in Canada and am looking to the future, a lot of the blogs this week are doing the same.

After the shock of the Oracle takeover the MySQL community is full of hope. Mark Callaghan has written about the new storage engines for MySQL and also suggestions for what the MySQL community could be doing while they wait to hear what Oracle has planned.

Kaj Arno has looked to the future and he thinks he has found some answers.

With the …

This is the 143rd edition of Log Buffer, the weekly review of database blogs.

So . . .  Anything happen while I was away?

Okay, so I heard the big news. And just in case you haven’t, here it is from Sheeri Cabral: Oracle Buys Sun. This is a sea-change in the hi-tech world, and the DB part of it will also get rocked, Sun being the home of MySQL. There’s lots of comment in Sheeri’s post, and indeed, all over the database blogging world. I will try here to cover the best of it.

Oracle + Sun + MySQL

Welcome to the 142nd edition of Log Buffer, the weekly review of database blogs.

The SQL Server ’sphere was a busy place this week. On In Recovery… Paul S. Randall posted his latest straw poll, this time looking into your practices around transaction log size management.

Linchi Shea observed, “In a multi-process/multi-thread system, locking is central to maintain data consistency and keep things in order.  . . . [We] need to begin with understanding the locking behavior of the basic building blocks offered by SQL Server . . .  [One] would think that the basic locking behavior …

Welcome to the 141st edition of Log Buffer, the weekly review of database blogs. The Oracle bloggers were especially chatty this week, so let’s start with them.

Rob van Wijk wrote a fine post about choosing between SQL and PL/SQL, defending his choice of straight-up SQL for logic. Naturally, this triggered a lot of discussion, as well as a few responses from other blogs. Chen Shapira framed her response in a question about code life-cycle: would you rather maintain SQL or PL/SQL?

I am passing this along — I am not sure if most folks reading this can make it, as it is last-minute and in the Boston area, but I figured I’d let people know that the New England Database Society exists. It’s free, sponsored by Sun (and has been for years, long before Sun bought MySQL), and is hosted by my college database professor, Mitch Cherniack. (To that end, I should probably make sure to promote the Boston User Group here more often! I keep forgetting…)

You can find information on how to be a part of the mailing list at http://www.cs.brown.edu/sites/neds/

The next New England Database Society will be held on Friday, March 27 and the speaker is Christian Jensen of Aalborg University.

This is the 140th edition of Log Buffer, the weekly review of database blogs. Welcome.

Let us begin with Oracle this week. Dan Norris illustrates how to start database services automatically after instance startup. He says, “Services are an essential component for managing workload in a RAC environment. If you’re not defining any non-default services in your RAC database, you’re making a mistake.”

Vivek Sharma published his tale of, Latch: Row Cache Objects causing huge performance issue. Clever detective …

In about 15 minutes, Giuseppe Maxia will begin a webinar in which the main focus is a presentation on “How to have a good presentation”. Talk about meta!

Giuseppe posted how to join the free webinar.

The Oracle gateway for ODBC provides an almost seamless data integration between Oracle and other RDBMS. I won’t argue about its performance, limits, or relevance. It serves a few purposes; set it up and you’ll be able, for example, to create database links between Oracle and MySQL. After all, wouldn’t it be nice if you could run some of the following SQL statements?

• select o.col1, m.col1 from oracle_tab
o, mysql_tab@mysql m where o.col1=m.col1;
• insert into oracle_tab (select * from mysql_tab@mysql);

This post is intended to share, the same way Karun did it for SQL Server …

Welcome to the 139th edition of Log Buffer, the weekly review of database blogs. Let us begin with a look at the best from the Oracle ’sphere.

Many of you might be considering some more training or certification. Coskan Gundogar has already been there, and has returned with the tale to tell, What I learned during Oracle SQL Expert Exam Study Part-1.
