This is not a new concept. The Extreme Programming (XP) agile methodology (1999) outlined the concept before the acronym became more widely accepted as “Another requirement is testability. https://ronaldbradford.com/blog/understanding-openstack-developer-dependencies-2015-05-27/ Wed, 27 May 2015 21:43:53 +0000 https://ronaldbradford.com/blog/understanding-openstack-developer-dependencies-2015-05-27/ While reviewing the OpenStack keystone codebase on an existing VM used with devstack I came across a dependency problem with Python pbr .

In absence of any MySQL monitoring for your site, I have found no solution that gets you operational as quickly and easily. MONyog can be deployed in 60 seconds, and configured in another 60 seconds. https://ronaldbradford.com/blog/mysql-permissions-restarting-mysql-2009-11-19/ Thu, 19 Nov 2009 18:10:34 +0000 https://ronaldbradford.com/blog/mysql-permissions-restarting-mysql-2009-11-19/ I am working with a client that is using managed hosting on dedicated servers. This has presented new challenges in obtaining the right permissions to undertake MySQL tasks but not have either ‘root’ or ‘mysql’ access and not have to involve a third party everytime. https://ronaldbradford.com/blog/monitoring-mysql-resource-limits-2009-10-27/ Wed, 28 Oct 2009 00:06:45 +0000 https://ronaldbradford.com/blog/monitoring-mysql-resource-limits-2009-10-27/ I have for the first time seen a client implement MySQL Resource Limits .

A: The bane of pain for MySQL DBA’s when there is no official MySQL instrumentation that is dynamic and fine grained sufficiently to solve this problem at the SQL interface. https://ronaldbradford.com/blog/simplicity-2009-10-07/ Wed, 07 Oct 2009 19:08:01 +0000 https://ronaldbradford.com/blog/simplicity-2009-10-07/ Simplicity – Always strive for a simpler solution. This is a principle I have held and have used for many years in my technology based profession. It’s very surprising that many organizations when addressing a problem forget to look at what is indeed right infront of them. https://ronaldbradford.com/blog/looking-just-at-the-data-2009-10-07/ Wed, 07 Oct 2009 18:35:38 +0000 https://ronaldbradford.com/blog/looking-just-at-the-data-2009-10-07/ There are many areas you need to review when addressing MySQL performance such as current database load, executed SQL statements, connections, configuration parameters, memory usage, disk to memory ratio, hardware performance & bottlenecks just to name a few. https://ronaldbradford.com/blog/what-alert-monitoring-do-you-use-2009-10-07/ Wed, 07 Oct 2009 17:14:05 +0000 https://ronaldbradford.com/blog/what-alert-monitoring-do-you-use-2009-10-07/ More importantly, how often to you confirm access to your server and database with that alert monitoring? With a client yesterday the primary database server while still usable and serving connections for a while, but was not accessible via SSH to investigate performance issues. https://ronaldbradford.com/blog/nosql-options-2009-10-06/ Tue, 06 Oct 2009 15:53:40 +0000 https://ronaldbradford.com/blog/nosql-options-2009-10-06/ The NoSQL event in New York had a number of presentations on non relational technologies including of Hadoop , MongoDB and CouchDB . Coming historically from a relational background of 20 years with Ingres , Oracle and MySQL I have been moving my focus towards non relational data store. https://ronaldbradford.com/blog/unexplained-function-output-2009-09-28/ Mon, 28 Sep 2009 22:39:49 +0000 https://ronaldbradford.com/blog/unexplained-function-output-2009-09-28/ I was asked today to confirm the operation of INET_ATON() and INET_NTOA() functions for converting IP4 strings to numeric representations. My tests on the machine I was just connected to at the very instant reported the following results. https://ronaldbradford.com/blog/mysql-query-cache-path-2009-09-28/ Mon, 28 Sep 2009 19:34:53 +0000 https://ronaldbradford.com/blog/mysql-query-cache-path-2009-09-28/ Just how effective is the Query Cache on performance? If you are not comfortable reading the MySQL code you can cheat very easily with the SHOW PROFILE command. This demonstration will show you at a high level the relative impact without and with the Query Cache. https://ronaldbradford.com/blog/using-the-mysql-query-cache-effectively-2009-09-28/ Mon, 28 Sep 2009 19:10:53 +0000 https://ronaldbradford.com/blog/using-the-mysql-query-cache-effectively-2009-09-28/ Maximize your strengths, minimize your weaknesses. You can apply this approach to many things in life, I apply it to describing and using MySQL the product, and it’s components. The Query Cache like many features in MySQL, and indeed features in many different RDBMS products (don’t get me started on Oracle *features*) have relative benefits. https://ronaldbradford.com/blog/explain-an-essential-tool-for-mysql-developers-2009-09-26/ Sat, 26 Sep 2009 15:46:45 +0000 https://ronaldbradford.com/blog/explain-an-essential-tool-for-mysql-developers-2009-09-26/ Just recently I came across the presentation “Bend SQL to your will with EXPLAIN” by Ligaya Turmelle via the Linked In – MySQL Speakers and Presenters group. Slides available at Slideshare . https://ronaldbradford.com/blog/calculating-your-database-size-2009-09-25/ Fri, 25 Sep 2009 05:06:15 +0000 https://ronaldbradford.com/blog/calculating-your-database-size-2009-09-25/ I generally use the following MySQL INFORMATION_SCHEMA (I_S) query to Calculate Your MySQL Database Size . This query and most others that access the MySQL INFORMATION_SCHEMA can be very slow to execute because they are not real tables and are not governed by physical data, memory buffers and indexes for example but rather internal MySQL data structures. https://ronaldbradford.com/blog/understanding-mysql-innodb-transaction-isolation-2009-09-24/ Thu, 24 Sep 2009 06:33:04 +0000 https://ronaldbradford.com/blog/understanding-mysql-innodb-transaction-isolation-2009-09-24/ The MySQL Innodb storage engine provides ACID compliance, the ‘I’ being isolation. There are four states defined in MySQL with the tx_isolation system variable, READ-UNCOMMITTED, READ-COMMITTED, REPEATABLE-READ and SERIALIZABLE. Generally MySQL installations do not modify the default value of tx_isolation = REPEATABLE-READ, however I have seen with a number of clients the default value has been changed to READ-COMMITTED. https://ronaldbradford.com/blog/identifying-resource-bottlenecks-disk-2009-09-18/ Fri, 18 Sep 2009 22:43:49 +0000 https://ronaldbradford.com/blog/identifying-resource-bottlenecks-disk-2009-09-18/ With a discussion on identifying CPU and Memory bottlenecks achieved, let us now look at how Disk can affect MySQL performance. One of the first steps when addressing a MySQL performance tuning problem is to perform a system audit of the physical hardware resources (CPU,Memory,Disk,Network), then identify any obvious bottlenecks in these resources. https://ronaldbradford.com/blog/mysql-show-privileges-2009-09-18/ Fri, 18 Sep 2009 21:39:16 +0000 https://ronaldbradford.com/blog/mysql-show-privileges-2009-09-18/ Some days you learn about MySQL commands even without knowing about them. Today I wanted to check the privileges a user had because they did not have permissions to drop a view. https://ronaldbradford.com/blog/more-woes-with-java-version-on-ubuntu-2009-09-18/ Fri, 18 Sep 2009 17:39:06 +0000 https://ronaldbradford.com/blog/more-woes-with-java-version-on-ubuntu-2009-09-18/ Armed with more information on Drizzle JDBC being a JDBC 4.0 implementation (helps to explain my issues in Getting started with Drizzle JDBC ) I took the time to read about some other new JDBC 4. https://ronaldbradford.com/blog/getting-started-with-drizzle-jdbc-2009-09-17/ Thu, 17 Sep 2009 23:19:35 +0000 https://ronaldbradford.com/blog/getting-started-with-drizzle-jdbc-2009-09-17/ In preparation for some Java work I wanted to configure and test the Drizzle JDBC Driver.
