Using PBXT 0.9.5

Paul has released Version 0.95 of his PBXT MySQL Transactional Storage Engine.

Here is what I did to get it operational under CentOS 4.3.

su -
useradd pbxt
su - pbxt
wget http://www.primebase.com/xt/download/mysql-4.1.16-pbxt-0.9.5.tar.gz
tar xvfz mysql-4.1.16-pbxt-0.9.5.tar.gz
cd mysql-4.1.16-pbxt-0.9.5
./configure --with-debug=full --with-pbxt-storage-engine --without-query-cache --with-mysqld-user=pbxt  --prefix=/home/pbxt/mysql
make
make install
scripts/mysql_install_db
cd /home/pbxt/mysql
./bin/mysqld_safe --user=pbxt --basedir=/home/pbxt/mysql &

Now, lets test and confirm PBXT is operational.

bin/mysql -uroot mysql

Now to take if for a spin with the MySQL Sakila Sample Database. At this time I need a modified version of the schema, as the sample database is designed for Version 5.

Download sakila.mysql4 script .
Download sakila.pbxt.sql script .

bin/mysql -uroot mysql
mysql>  source sakila.mysql4
mysql> source  sakila.pbxt.sql
# NOTE: Alter table of film_text fails as expected due to FULLTEXT index
mysql> show create table actor;
mysql> exit;

A few warnings in my sakila.mysql4 script I’ll need to review, but it looks ok from an installation step. Now back to my tests that I’m writing to use the Sakila Sample Database which I was working on, so I can really test the ACID state and performance of PBXT.
