I’m attempting to test my app on Rails 2.0 RC1. I used this command: rake rails:freeze:edge TAG=rel\_2-0-0\_RC1 My database adapter is OCI for Oracle 8i. However, when I try to start up mongrel in my dev environment, I get the following message: C:/rails/tms/vendor/rails/activerecord/lib/active\_record/ connection\_adapters/abstract/connection\_specification.rb:231:in `establish_connection': Please install the oci adapter: `gem install activerecord-oci-adapter`(no such file to load -- active_record/ connection_adapters/oci_adapter) (RuntimeError) from C:/rails/tms/vendor/rails/activerecord/lib/active_record/ connection_adapters/abstract/connection_specification.rb:215:in`establish\_connection’ from C:/rails/tms/vendor/rails/activerecord/lib/active\_record/ connection\_adapters/abstract/connection\_specification.rb:208:in `establish_connection' from C:/rails/tms/vendor/rails/railties/lib/initializer.rb: 234:in `initialize\_database’ from C:/rails/tms/vendor/rails/railties/lib/initializer.rb: 94:in `process' from C:/rails/tms/vendor/rails/railties/lib/initializer.rb: 49:in `send’ from C:/rails/tms/vendor/rails/railties/lib/initializer.rb: 49:in `run' from C:/rails/tms/config/environment.rb:13 from C:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 27:in `gem\_original\_require’ … 25 levels… from C:/rails/tms/vendor/rails/railties/lib/commands/server.rb: 39 from C:/ruby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb: 27:in `gem_original_require' from C:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 27:in `require’ from script/server:3 So, I tried to run the suggested command ‘gem install activerecord-oci- adapter’, but I get the following error: C:\rails\tms\>gem install activerecord-oci-adapter ERROR: While executing gem … (Gem::GemNotFoundException) Could not find activerecord-oci-adapter (\> 0) in any repository C:\rails\tms\>gem install activerecord-oci-adapter --source [http://gems.rubyonrails.org](http://gems.rubyonrails.org) ERROR: While executing gem … (Gem::GemNotFoundException) Could not find activerecord-oci-adapter (\> 0) in any repository When I look around, the string ‘activerecord-oci-adapter’ does not exist anywhere on google, Rails Trac, or google groups. Does this gem actually exist? What am I missing? Thanks, Ian. ---

Odd that Rails instructs the user to do something that is impossible, isn’t it? Hehe… maybe that’s why it’s a Release Candidate. Well, I had already installed the activerecord-oracle-adapter and I was still getting the error looking for activerecord-oci-adapter. So, I went into C:\ruby\lib\ruby\gems\1.8\gems\activerecord-oracle- adapter-1.0.0\lib\active\_record\connection\_adapters and renamed oracle\_adapter.rb to oci\_adapter.rb. This makes things start working. Looks like DHH renamed the adapter here: [http://dev.rubyonrails.org/changeset/3718](http://dev.rubyonrails.org/changeset/3718) but this is somehow not working 100% in the RC1. Not really sure where the problem lies. Thanks, Fred! Ian. On Nov 15, 1:14 pm, Frederick C. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Does this gem > actually exist? What am I missing? Nope, it doesn’t exist. activerecord-oracle-adapter does however 🙂 ( you still need to say --source [http://gems.rubyonrails.org](http://gems.rubyonrails.org)) Fred ---

Ian, I think you are just supposed to change your config/database.yml to look more like: * * * ## development: adapter: oracle host: localhost database: XE username: user password: pass ## Rather than, ## development: adapter: oci host: XE username: user password: pass The second snippet is what I had working for 1.2.5. ## Now I just have my Rails application bombing on a specific action: ## BlaModel Load (0.001817) select \* from (select raw\_sql\_.\*, rownum raw\_rnum\_ from (SELECT \* FROM bla\_models WHERE (bla\_models.name = ‘ACCT0502’) ) raw\_sql\_ where rownum \<= 1) where raw\_rnum\_ \> 0 /usr/lib/ruby/gems/1.8/gems/activerecord-oracle-adapter-1.0.0/lib/active\_record/connection\_adapters/oracle\_adapter.rb:571: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i386-linux] Any thoughts on this issue? I’m still investigating, but if I can’t figure it out in the 1 hour I will have to revert back to 1.2.5 for work sanity. SP ---

That did the trick. Thank you very much! However, I have no idea why you’re getting that segfault. ☹ I haven’t come across that yet. On Nov 24, 5:16 pm, “S. Potter” [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---
