ActiveRecord::AdapterNotFound - oci8 problems

Rails
1

I have resolved all the problems with OCI8Errors (you should see
http://rubyforge.org/forum/forum.php?thread_id=47776&forum_id=1078 for
more information). Now there is connecting to my DBMS without
errors :)))

OS: Win_XP_home
DBMS: Oracle XE 10g

Well. When I connect to DBMS by command line, it’s ok. When I am
starting a webserver in rails application (in NetBeans), it isn’t ok.
I see an error:

I have googled this error and found 1 good solution:

In Ruby DBI: Database Access ,
“Round up the usual suspects”.
According to this advise, I have installed Ruby-DBI (oci8 installed
ages ago)
But the error above doesn’t disappear.

Do you know how to resolve this problem?

The solution is:

[QUOTE=“happs74”]I use rails & oracle on xp. To get it all working I
did

Gem install ruby-oci8
Gem install activerecord-oracle_enhanced-adapter
add config.gem “activerecord-oracle_enhanced-adapter”, :lib =>
“active_record/connection_adapters/oracle_enhanced_adapter” to
environment.rb
set your adapter in database.yml to be oracle_enhanced and see how you
get on.[/QUOTE]
I have installed ruby-oci8 и activerecord-oracle_enhanced-
adapter and reconfig database.yml.
