IntroductionThe following instructions will lay out an installation of MySQL on Linux using the MySQL Optimal Configuration Architecture (MOCA) for someone with fundamental knowledge of MySQL and basic Linux administration skills. MOCA is a set of best practices I put together to lay out a set of guidelines for installing and configuring a MySQL database server. MOCA is designed for someone with
Believe it or not, I haven't put myself into this position
before. The day before yesterday I started a LOAD DATA INFILE for
760 million rows. Didn't really think too hard about it, figured
I'd let it run until it finished.
Unfortunately MySQL did that thing where the row insertion rate
slowed to molasses over time, and the box was hosed. I killed the
query. So it started rolling back the transaction. Which was 431
million rows in.
Using `SHOW ENGINE INNODB STATUS` you can look at the number of
undo entries a transaction has left to go:
---TRANSACTION 0 1161525892, ACTIVE 18598 sec, process no 20139, OS thread id 1131772224 ROLLING BACK , undo log entries 431301691
Something like that. I left it to rollback overnight. The next
day, it had only moved through a few million entries. It's going
to take a week or more! I could just drop the table but it's
locked from the transaction …

Dear Community,
As of today Release 9 of XtraDB storage engine is available.
The release includes following new features:
Fixed bugs:
Since Ubuntu 8.04 aka Hardy Heron, I've had issues
with every new release. As Ubuntu evolves into being a viable
desktop OS alternative, its complexity has been growing and with
the new and improved looks new challenges arise. This bug in
particular has been very difficult to diagnose and I can't
imagine anyone without enough Linux experience to overcome it on
their own, so I decided to summarize the steps I took to fix it
... and vent my frustration at the end.
The SymptomI came across the issue for the first time while
trying Ubuntu's Karmic Netbook remix. After overcoming the
typical Broadcom wifi driver, Network Manager would
connect, but Firefox would fail to load the web pages 90%
of the time. Using ping in the command line worked just
fine. Maybe I needed to update the software packages to get the
latest patches, surprise, apt-get was having similar
problems and timing out. So the problem …
I began porting the dba module to Drupal 7 as an opportunity to learn more about the new database abstraction layer. In this upcoming Drupal release, our database layer is now built upon the PHP Data Objects (PDO) data-access abstraction layer, introducing new syntax and symantecs into writing queries with Drupal. A powerful new query builder makes it possible to easily write queries that run on any database type supported by Drupal, currently including MySQL, PostgreSQL and SQLite.
The dba module was always intended to be a useful tool for any database administrator, and toward that end I have recently merged in mysqlreport functionality which utilizes MySQL's server statistics to offer an overview of server health and performance. As an …

Oracle, after dating HP, Dell, Netapp and EMC has found its mate
in Sun. Oracle is now becoming a systems company, and unceremoniously dumping
these former paramours. These leaves the spurned lovers to find
alternate accommodations, especially in the area of the
database.
As I have stated previously on this blog, the clear partner of
choice on the Windows front is Microsoft. This is demonstrated by
today’s partner announcement around MS SQL Server for
OLTP. But who is their partner in the Linux segment?
The following are contenders:
* Postgres (HP rolls their own)
* EnterpriseDB (pre-rolled Postgres)
* Ingres or Sybase—Oracle has felled them both in the past, …
It didn’t take long, but the advanced analytics reporting code has been added to the command line reporter version of Kontrollbase.
