Is there a way through which I see which mysql queries are fired from ActiveRecord in rails console?

http://stackoverflow.com/questions/4667316/how-to-see-mysql-queries-in-rails-console

Yes, this can be achieved through redirecting rails log to standard output.

Write these at your console prompt:

ActiveRecord::Base.logger = Logger.new(STDOUT)
ActiveRecord::Base.connection_pool.clear_reloadable_connections!
Furthermore, you can put these lines in ~/.irbrc file, so that each time you don't need to manually write these 2 lines:

require 'rubygems'

if ENV.include?('RAILS_ENV') && ENV["RAILS_ENV"] == 'development'
    ActiveRecord::Base.logger = Logger.new(STDOUT)
    ActiveRecord::Base.connection_pool.clear_reloadable_connections!
end

If you're crashing on the splash screen right after it the RMI initialization message try passing the -noRmi flag to mimo.exe. In the start menu right click on Mimo, select properties, and add the flag to the target. Mine looks like this:

"C:\Program Files (x86)\Mimo\Mimo.exe" -noRmi

You should see an "RMI Disabled" message on the splash screen.

Oracle, Ruby, RVM, and OSX Lion

As of this writing the x64 version of the Oracle Instant Client do NOT work with OSX Lion. I got everything working like so:

Install Oracle Instant Client

Install the 32 bit version of the Oracle Instant Client. Download and install the following packages to /usr/local/oracle/instantclient_10_2

1. instantclient-basic-10.2.0.4.0-macosx-x86.zip
2. instantclient-sqlplus-10.2.0.4.0-macosx-x86.zip
3. instantclient-sdk-10.2.0.4.0-macosx-x86.zip

Install the 32-bit version of Ruby

brew install libyaml

rvm install 1.9.3 -n i386 --with-arch=i386

rvm use ruby-1.9.3-p194-i386

Bash

Add the following to your .bash_profile

export DYLD_LIBRARY_PATH="/usr/local/oracle/instantclient_10_2"
export TNS_ADMIN="/usr/local/oracle/network/admin/"
export SQLPATH="/usr/local/oracle/instantclient_10_2"
export ORACLE_HOME="/usr/local/oracle/instantclient_10_2"
export NLS_LANG="AMERICAN_AMERICA.UTF8"
export PATH="$PATH:/usr/local/bin/"
export PATH="$PATH:/usr/local/oracle/instantclient_10_2"

Open and use a new terminal going forward.

tnsnames.ora

Create a tnsnames.ora file here:

/usr/local/oracle/network/admin/tnsnames.ora

Mine looks like this:

staging_db =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 123.456.789.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = FOO)
    )
  )

Try it

ruby -rubygems -e "require 'oci8'; OCI8.new('username','password','staging_db').exec('select * from users where rownum < 2') do |c| puts c.join(','); end;"
