I have a recipe that downloads a compiled version of the ruby-oci8 gem and
installs it. Then I use a custom LWRP to access the database and populate a
schema e.g.:
recipe/default.rb
oci8 = remote_file node[‘oracle’][‘gems’][‘oci8’][‘archive’] do
source node[‘oracle’][‘gems’][‘oci8’][‘url’]
checksum node[‘oracle’][‘gems’][‘oci8’][‘checksum’]
mode "0644"
action :nothing
end
oci8.run_action(:create)
chef_gem “ruby-oci8” do
action :install
source node[‘oracle’][‘gems’][‘oci8’][‘archive’]
end
providers/schema_oracle.rb
private
def database_connection
@db ||= begin
require 'oci8’
connection = OCI8.new("#{node[“database”][“username”]}",
"#{node[“database”][“password”]}",
"#{node[‘oracle’][‘db’][‘service_name’]}")
Chef::Log.debug(“Created connection to #{connection.username}”)
connection
end
end
But, during the first run of chef-solo when I try to require 'oci8' in my
provider I get an Argument error (shown below). Running chef-solo a second time
does not produce this error and the cookbook completes as expected.

ArgumentError
wrong number of arguments (2 for 0…1)

From the stacktrace above
/opt/chef/embedded/lib/ruby/gems/1.9.1/gems/ruby-oci8-2.1.5-x86_64-linux/lib/oci8.rb:81
is trying to require
/opt/chef/embedded/lib/ruby/gems/1.9.1/gems/ruby-oci8-2.1.5-x86_64-linux/lib/oci8lib_191.so
which seems to be the root cause of the problem, but I don’t know enough about
Chef to debug this any further than that. This is my first attempt at a Chef
cookbook so I may be overlooking something obvious but I would really
appreciate any pointers.
Thanks,
Peter
