Integration testing of Java EE developments is an important topic both Markus Eisele and Antonio Goncalves have recently covered in respective blogs.
Both use GlassFish and Arquillian while Antonio shows different testing approaches and also throws Mockito into the mix.
[Read more...]Once upon a time, it would have been considered madness to even attempt to create 30,000 tables in InnoDB. That time is now a memory. We have customers with a lot more tables than a mere 30,000. There have historically been no tests for anything near this many tables in the MySQL test suite.
So, in fleshing out the test cases for this and innodb_dict_size_limit I was left with the not so awesome task of making the test case run in remotely reasonable time. The test case itself is pretty simple, a simple loop in the not at all exciting mysqltest language that will create 30,000 identical tables, insert a row into each of them and then drop them.
Establishing the ground rules: I do not care about durability. This is a test case, not

One of our colleagues, Dimitri, at the Paris Sun solution center has developed a real neat and useful tool called dim_STAT. To make it short it's a tool for both high-level and detailed, monitoring and performance analysis of Solaris and Linux systems.
Data is collected and saved in a MySQL database, and it provides a very functional web base user interface. It allows real time or off line monitoring, multi-host etc.
Actually what is really interesting with dim_STAT is that, when I'm benchmarking or tryinng to find a performance bottleneck, I can collect all the data I need and come back later for analysis.
Recently, Dimitri has added a new tool db_STRESS, that allows us to put load on a database system and gives a high level metric (TPS: Transactions per seconds) and therefor allows us to compare how different systems
