I have tried switching the databases from right to left and the other way but still getting the same error. Is there a solution to this problem? Kindly help.

redmine.conf
RR::Initializer::run do |config|
  config.left = {
    :adapter  => 'mysql', # or 'mysql'
    :database => 'xxxxx',
    :username => 'xxxxx',
    :password => 'kenic1461',
    :host     => 'xx.xx.xx.2'
  }

  config.right = {
    :adapter  => 'mysql',
    :database => 'xxxxx',
    :username => 'xxxxxx',
    :password => 'xxxxx',
    :host     => 'xx.xx.xx.2'
  }

  #config.include_tables 'dept'
  #config.include_tables /^e/ # regexp matching all tables starting with e
   config.include_tables /./ # regexp matching all tables in the database
   config.options[:auto_key_limit] = 2
end
