Website health checks are a crucial service to an operations team. In addition to in-house monitoring and service state reporting it’s also important, even critical, to have an impartial third party to run checks to test your customer facing services. There are a lot of companies in this arean that would be glad to have [...]

The DDL code paths for Drizzle are increasingly different from MySQL. For example, the embedded_innodb StorageEngine CREATE TABLE code path is completely different than what it would have to be for MySQL. This is because of a number of reasons, the primary one being that Drizzle uses a protobuf message to describe the table format instead of several data structures and a FRM file.

We are pretty close to having the table protobuf message format being final (there’s a few bits left to clean up, but expect them done Real Soon Now (TM)). You can see the definition (which is pretty simple to follow) in drizzled/message/table.proto. Also check out my series of blog posts on the table message …

Taking TOTD #121 forward, this blog explains how to create a JPA Persistence Unit for a MySQL sample database and package it as a library. This JAR file can then be easily included in other web applications.

Lets get started!

1. Configure GlassFish for using the MySQL sample database (sakila) as described in TOTD #121.
2. Add the GlassFish instance in NetBeans IDE using "Services" panel.
3. Create JPA entities using NetBeans IDE.
   1. Create a Java class library:

This blog clearly explains how to configure the MySQL sample database (sakila) with GlassFish. Even though the instructions use a specific database but should work for other databases (such as Oracle, JavaDB, PostgreSQL, and others) as well. The second half of the blog provide specific syntax for the Oracle sample database.

1. Download sakila sample database and unzip the archive.
2. Install the database as described here - basically load and run "sakila-schema.sql" and "sakila-data.sql" extracted from the archive.
3. Create a new MySQL user account using MySQL CLI Admin and assign the privileges
   …

Bernhard blogged over at http://ocklin.blogspot.com/2010/02/mysql-cluster-711-is-there.html that MySQL Cluster 7.1.1 Beta has been released. The big feature (from my point of view) is the SQL interface on top of NDB$INFO. This means there is now full infrastructure from the NDB data nodes right out to SQL in the MySQL Server for adding monitoring to any bit of the internals of the data nodes.
