I have successfuly connected to a local mySql db and am now trying to connect to DB2 on MVS from an XP box (error message below). Do I need to explicitly install something or run some setup ... I didn''t need to for mysql. What files should be where? My database.yml: development: adapter: db2 database: <dbname> host: <hostname> userame: <username> password: <password> When I start the server I get: -----begin error c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.10.1/lib/active_record/ connection_adapters/abstract_adapter.rb:83:in `establish_connection'': database configuration specifies nonexistent db2 adapter (ActiveRecord::AdapterNotFound) from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.10.1/lib/active_record/ connection_adapters/abstract_adapter.rb:75:in `establish_connection'' from c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.10.1/lib/active_record/ connection_adapters/abstract_adapter.rb:70:in `establish_connection'' from ./script/../config/environment.rb:47 from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in `require__'' from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in `require'' from script/server:42 -----end error
