Running the DBT2 test results in 0.00 NOTPM I'm trying to run the MySQL DBT2 Benchmark Tool, I have unzipped the archive and run the following commands:

./configure --with-mysql
make
make install
mkdir /tmp/dbt
datagen -w 3 -d /tmp/dbt --mysql
scripts/mysql/mysql_load_db.sh --path /tmp/dbt --mysql-path /usr/bin/mysql
scripts/run_mysql.sh --connections 20 --time 300 --warehouses 3


But got the following output:

During the execution, SHOW PROCESSLIST did show that 20 clients were connected, all sleeping.

Any idea why no transactions are executed?
I have done the following to reproduce the output you are seeing from dbt2.


Installed Centos6.4 
Installed MySQL 5.1.69 via YUM
Installed Innotop to view in real time all queries and open transactions


Ran the bench as you did:

[root@centos-cef dbt2-0.37.50.3]# scripts/run_mysql.sh --connections 20 --terminals 5 --time 300 --warehouses 3 --verbose


Innotop only showed 20 active clients but no open queries or transactions

DBT2 provides several logs. On the system I used for testing, there was a main directory /root/output and then a number for each execution.

/root/output/N where N is the execution number. 

In the file /root/output/3/client/error.log, I found the following information

I'm seeing ROLLBACK INITIATED throughout the log. I am also seeing that certain stored procedures are not installed such as dbt2.payment

So I looked a little further and there is another script that has to be run in order to create the stored procedures in the dbt2 database.

scripts/mysql/mysql_load_sp.sh --database dbt2 --client-path /usr/bin/


Which gives the following output:

Load SP: delivery
Load SP: new_order
Load SP: new_order_2
Load SP: order_status
Load SP: payment
Load SP: stock_level


Have you run 

scripts/mysql/mysql_load_sp.sh --database dbt2 --client-path /usr/bin 


on your server to load in the stored procedures?

After loading in DBT2's stored procedures, I ran DBT2 again and this time I did see transactions in Innotop's output

[RO] InnoDB Txns (? for help)                             localhost, 2h7m, InnoDB 1s :-), 765.68 QPS, 22/0/0 con/run/cac thds, 5.1.69

ID   User  Host       Txn Status  Time   Undo  Query Text
217  root  localhost  COMMITTED   00:00     0  COMMIT    


I noticed though as you did, that DBT2's output was still showing O's everywhere, so I increased the number of warehouses to 30. My thinking was that there wasn't enough transactions or activity to generate useful results

scripts/run_mysql.sh --connections 20 --time 300 --warehouses 30 --verbose

And as you can see, DBT2 sent back appropriate results this time.
