to Oracle enhanced adapter for ActiveRecord
Hello again,
a smaller issue when I set the activerecord-oracle_enhanced-adapter
gem dependency in my config/environment.rb:
no such file to load -- activerecord/oracle_enhanced/adapter
/opt/ruby-enterprise-1.8.6-20080810/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in `gem_original_require'
/opt/ruby-enterprise-1.8.6-20080810/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in `require'

148:in `require'
.../vendor/rails/activesupport/lib/active_support/dependencies.rb:
507:in `new_constants_in'

.../config/environment.rb:15
Now, what is really odd is that apache" + mod_rails are working fine,
with or without that config.gem. Speaking of oddities (which might be
unrelated):
$ ruby -r oci8 -e "OCI8.new('c', 'b','c').exec('select * from dual')
do |r| puts r.join(','); end"
ruby: no such file to load -- oci8 (LoadError)
$ irb
>> require 'oci8'
=> true
>> OCI8.new('c', 'b','c').exec('select * from dual') do |r| puts r.join(','); end
=> 1
The activerecord test works too and
$ ruby -r rubygems -e 'puts Gem.path'
/opt/ruby-enterprise-1.8.6-20080810/lib/ruby/gems/1.8
/var/lib/gems/1.8
which is expected and the obi8 lib is installed there
$ ls -d /opt/ruby-enterprise-1.8.6-20080810/lib/ruby/gems/1.8/gems/
ruby-oci8-1.0.3
/opt/ruby-enterprise-1.8.6-20080810/lib/ruby/gems/1.8/gems/ruby-

any clue?

1. Do you have just Ruby Enterprise Edition on this computer? No
original MRI? (Just wanted to be sure that there are no conflicts
between different Ruby installations)
2. It seems that there are some issues with oci8 installation if you
got "no such file to load" issue. Have you compiled and installed ruby-
oci8 library or have you installed it with "gem install ruby-oci8"?
If you have installed as gem then try
require ‘rubygems’
gem ‘ruby-oci8’
require 'oci8'
OCI8.new('user', 'password', 'database').exec('select * from dual') do

not really (as far as I understand), Rails was complaining about that.
To work it around I installed the gem in the Rails tree (using rails
2.2.0 and rake gems:install) and added the definition as outlined in
my previous post.

I thought this could be the problem. I had ruby-1.8 and ruby-1.9

OK, so it seems that all the components (ruby-oci8 and
oracle_enahnced) are working.
Then the question about your environment.rb. I use the following line
there:
config.gem "activerecord-oracle_enhanced-adapter", :lib =>
"active_record/connection_adapters/oracle_enhanced_adapter"
Do you use it in the same way?
In addition I am also using ruby-plsql gem and have the following line
in environment.rb:
config.gem "ruby-plsql", :lib => "ruby_plsql"
oracle_enhanced tries to require ruby-plsql library as well but if it
is missing then it should work also without it.
But maybe you can try to install ruby-plsql gem as well and include it
in your environment.rb file.

When using the oracle_enhanced adapter with REE, I've had to install
both the ruby-oci8 library and the gem to get it to work.
Also if you want to use it with passenger, then you'll need pass the
LD_LIBRARY_PATH to passenger, since it doesn't take it from the
environment, there's a lil' hack I've found somewhere, I just don't
have it right now. Let me know if you need it, so I search for it.

I also just found that the issue is that Passenger starts with very
few environment variables and actually ruby-oci8 library cannot be
load because of missing LD_LIBRARY_PATH environment variable.
Try to put in environment.rb
require "oci8"
before
config.gem "activerecord-oracle_enhanced-adapter", ...
to verify if you can load oci8 library.
One workaround for setting environment variables for Passenger I wrote
in my blog post
http://blog.rayapps.com/2008/05/21/using-mod_rails-with-rails-applications-on-oracle/
Recently I found that you can also use envvars file for setting Apache
environment variables but somehow it does not work anymore on my Mac
(the file is /usr/sbin/envvars and it is executed in apachectl
script). If anyone knows what could be the issue I would like to hear
it.
There is currently issue registered in Passenger issue register about
supporting SetEnv Apache configuration directive but currently it is
not yet implemented:

I found how to correctly add environment variables to Apache httpd
process in Mac OS X 10.5.
Edit /System/Library/LaunchDaemons/org.apache.httpd.plist
and add the following lines after <dict> line:
<key>EnvironmentVariables</key>
<dict>
<key>DYLD_LIBRARY_PATH</key>
<string>/usr/local/oracle/instantclient_10_2:/usr/lib</string>
<key>NLS_LANG</key>
<string>AMERICAN_AMERICA.UTF8</string>
<key>TNS_ADMIN</key>
<string>/usr/local/oracle/network/admin</string>
</dict>
Adjust environment variables according to your Oracle Instant Client
location.
On Linux it seems that you should use envvars file to set up Apache
environment variables. Look in your apachectl (or apache2ctl) script
where it is looking for envvars file.

I don't have ruby-plsql and as expected ruby-oci8 is doing just fine.

this did it! my bad for not looking more carefully at the :lib option.
