I’ve been looking over the documentation lately and trying to find ways to improve the installation experience for new users. That said, I’ve written a short but useful description of the easiest way to install all of the Perl and PHP requirements for Kontrollbase. You can find it here: http://kontrollsoft.com/kontrollbase/userguide/installation-install_overview.php#simple – or in the Installation [...]

A new version of Kontrollbase – the enterprise monitoring, analytics, reporting, and historical analysis webapp for MySQL database administrators and advanced users of MySQL databases – is available for download. See the downloads page or run “svn update” to get your new version today. http://kontrollsoft.com/software-downloads

I've just publicly released another Postgres-related script, this one called "boxinfo". Basically, it gathers information about a box (server), hence the catchy and original name. It outputs the information it finds into an HTML page, or into a MediaWiki formatted page.

The goal of boxinfo is to have a simple, single script that quickly gathers important information about a server into a web page, so that you can get a quick overview of what is installed on the server and how things are configured. It's also useful as a reference page when you are trying to remember which server was it that had Bucardo version 4.5.0 installed and was running pgbouncer.

As we use MediaWiki internally here at End Point (running with a Postgres backend, naturally), the original (and default) format is HTML with some MediaWiki specific items inside of it.

Because it is meant to run on a wide a range of boxes as possible, it's written in Perl. …

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. Click here to see an example of the tuning and analytics report output (html format). Now you have all of the reporting features (minus the growth over time) features that are offered in the [...]

I've been pretty quiet lately, because I'm in a transitional period. After 10 years on documentation for Oracle Database and other enterprise server products, I'm switching to the InnoDB group that already works with MySQL. New development environments, new customers, it's an exciting time!A decade seems to be the right timeframe for me. It was 10 years at IBM before that. Check back in 2019, I'm

If you have recently downloaded or checked out a new version of Kontrollbase and find that you need to upgrade the schema from a previous version then you will probably find this post useful. If you don’t know if you need to upgrade then you probably do, so read along for a bit just to [...]

When we wanted to quickly process intermediate data by using temporary or heap tables; then its normal tendency to create a table like its source table; so people will simply opt for CREATE TEMPORARY TABLE temp_table LIKE source_table.

This is an easy and convenient way. But the problem is if you have a simple stored procedure or code module that gets executed frequently, then you might indirectly experience a slow-down in the performance if your source_table is large enough and highly contended. Things will be really worst if concurrent threads starts using the source_table or in combination of source_table and CREATE LIKE.. statements and can lead to disaster scalability issues. The main reason for the post is; I noticed from SHOW PROCESSLIST from random servers where X threads getting into WAITING for TABLE lock state for simple …

This tweet from former MySQL AB CEO Mårten Mickos caught my eye. It shows a trend of increased demand for MySQL and PostgresSQL expertise while job postings on job websites for  those with Oracle and Ingres expertise declined.

I was a little shocked by the graph until you realize it’s just a trend. I then looked at the absolute number of jobs requesting database expertise and the story quickly becomes clear….
