In all versions we updated Apache to 2.2.8, PHP4 to 4.4.8 and phpMyAdmin to 2.11.4. The Linux and Mac OS X versions contain also updated Perl (5.10.0) and MySQL (5.0.51a) releases.

We recently integrated MySQL 5.0.45 version with Open Solaris.
MySQL 5.0.45 is available in SXDE 01/08. Sun Studio was used to
compile MySQL on both Solaris SPARC and Solaris AMD64
platform.
This blog entry describes the changes that were made to improve
MySQL performance using Sun Studio:
MySQL 5.0.45 is integrated with Open Solaris build 79. It is
available in Solaris Express Developer Edition (SXDE) 01/08.
MySQL 5.0.45 is integrated with Solaris Service Management
Facility (SMF).
This blog entry describes the steps that were taken to integrate
MySQL with SMF.
First a quick recap of what is SMF:
SMF is the core component of the predictive self-healing
technology available in Solaris 10, which provides automatic
recovery from software and hardware failures as well as
adminstrative errors.
Some of the advantages of using SMF are as under:
Failed services are automatically restarted in dependency order, whether they failed as the result of administrator error, software bug, or were affected by an uncorrectable hardware error.

For the first couple of years after we created the opentaps Open Source
ERP + CRM, we thought about our community as many other open
source projects do. We defined our "community" as the sum of all
the users, developers, and contributors of opentaps, and we asked
ourselves questions like "What can we develop for our community?"
and "How do we increase the size of our community?"
Only much later did I realize that this is completely wrong. It
is wrong because an open source project is not an island, but
rather part of a greater open source community that really
comprises of all the open source projects out there. In that
sense, there is no such thing as "our" community or "your"
community. Instead we are all part of one open source community
that is linked together and ultimately succeeds or fails
together.
What has created this greater open source community is simply …
Thanks all for the help on getting my log_addpartition event
running, dynamic SQL was just the ticket.
I'm now focusing on writing the sister event:
'log_removepartition', which will find and purge partitions older
than some time interval. The information schema comes in quite
handy here, as I can query the PARTITIONS table to see all
partitions.
Last time, I introduced the notion of strict and lenient updates. Now it’s time to see what the performance characteristics are of each.
Just to rehash, we are focusing on the storage engine (a la MySQL) level, and we are looking at a database on a single disk—the one we are using for illustration is the 1TB Hitachi Deskstar 7K1000. It has a disk seek time 14ms and transfer rate of around 69MB/s [See tomshardware.com] We will insert and delete random pairs, each 8 bytes. So that’s 62.5 billion pairs to fill the disk.
Strict Updates
These are the easier update types to analyze. Please review the definition of strict updates from the last blog entry. Now notice that each insertion or deletion requires a point query. For example, during an insertion, in order to determine if there’s already a row with a particular key value in the database, one must look up that key. In order …

I’m following what ezComponents doing for sometime now.
Quite nice framework for whatever you need.
I gave a try to write a mysql schema sync.
Real easy to write. only 4-5 lines of code to sync schemas.
It would have been great if it was actually working. The outout
sql ddl is not runnable in some cases (syntax errors). Or the
order of the columns are different.
I’m sure they’ll fix it soon but this tells me they are not yet
ready for production quality.
See the code below, maybe I’m doing something wrong.
<?php
require_once "ezcomponents/Base/src/base.php";
function __autoload( $className ){
ezcBase::autoload( $className );
}
$sourcedb['host']= isset($_POST['sourcedb']['host'])?
$_POST['sourcedb']['host']:”;
$sourcedb['port']= …

There are currently three derivates of MySQL Cluster 5.1:
In this post I will explain what features exists where, what they
do and what they mean and how they can be used. Why 5.1
The way to read it is as follows: Whatever is included in MySQL
Cluster 5.1, is also in MC 6.2 and 6.3. Whatever is in 6.2 is
also in 6.3.
What version you should use depends on what features you need,
but MC6.2 is more mature than 6.3 at the point of writing and is
used in production in a number of places of some of the largest
telco's in the world. MC 6.3 is a version that many of our
customers are developing and testing on right now.
Moreover, the MC versions are currently only available in source
distributions. Next post I will explain how to build it on the
Linux platform.
