If you cf ssh into your running app, and take a look at the config/database.yml file, has it been rewritten or does it match the config/database.yml contents on your local machine?

Hi Rochester,

It matches the config/database.yml on my local machine.

Daivd-Office-Mac:pong_matcher_rails-master ubuntu$ cf ssh railspong
vcap@qtnnq0qgbuu:~$ cd app
vcap@qtnnq0qgbuu:~/app$ more config/database.yml
default: &default
adapter: mysql2
encoding: utf8
pool: 15
username: root

port: 3306

Hi @David-Pivotal, we tried this out with a rails 4 fixture app that uses mysql2 and a connection pool of 15. We were unable to reproduce your issue's behavior.

Our steps:
In local environment:

git clone [email protected]:cloudfoundry/ruby-buildpack.git
git checkout pool-connection-15
cd cf_spec/fixtures/rails4_web_app
cf push rails4

Inside SSH session:

cf ssh rails4
cd app
export HOME=$(pwd)
source .profile.d/ruby.sh
rails c

In the rails console while inside the ssh session:

Loading production environment (Rails 4.1.8)
irb(main):001:0> ActiveRecord::Base.connection_pool.instance_eval { @size }
=> 15

Hi Rochester,

Thanks for your help. It is really helpful. I will check and get back to you soon.

Hi Rochester,

I am able to set connection pool size to 15. Please feel free to close this issue.
Thank you for your help!
