* Make the project drawer appear on the left or right.
From the menubar select View, then Hide Project Drawer.
Move your TextMate editor window over to the left side of the screen so the project gutter won’t have enough room to open up on that side. (You can move the window all the way to the left if you want, but you don’t need to go that far.)
Select View, then Show Project Drawer, and the drawer will now open on the right side of your TextMate editor.

In summary, install Oracle Instant Client and try to run sqlplus. If sqlplus connects to the oracle sid then go ahead and install the rails adapters for oracle. What is important to note here, is to install the oracle-instantclient for the architecture of your machine.. I have tested this on Debian Lenny (i386) and CentOS5 (x64)
1. Download from http://www.oracle.com/technology/software/tech/oci/instantclient/
a. oracle-instantclient-basic-10.2.0.4-1.i386
b. oracle-instantclient-devel-10.2.0.4-1.i386
c. oracle-instantclient-sqlplus-10.2.0.4-1.i386
2. Unzip everything to /opt/oracle/instantclient . You should have something like the ff:
[root@csapp1 instantclient]# ls -la
total 102704
drwxr-xr-x 3 root root 4096 Dec 10 21:54 .
drwxr-xr-x 3 root root 4096 Dec 10 22:03 ..

[root@csapp1 instantclient]#
3. Make a symbolic link for libclntsh.so.10.1 as shown above.
4. Create the Oracle Environment variables
export ORACLE_HOME=/opt/oracle/instantclient
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME:$LD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME
5. At this point, you should have oracle-instantclient properly installed. You can test by running sqlplus.
[root@csapp1 instantclient]# sqlplus
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 11 11:47:40 2008
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
NOTE: Sometimes you will get a SEGMENTATION FAULT. If so, try to open a new shell with the environment variables loaded and do an sqlplus in a directory which is not /opt/oracle/instantclient.
6. Install the oracle adapter for rails
7. gem install ruby-oci8
8. gem install oracle_enhanced-adapter –source=”http://gems.rubyonrails.org/”
activerecord-oracle-adapter (1.0.0.9250)
activerecord-oracle_enhanced-adapter (1.1.8)
NOTE: Try to look for the latest gems, the source above is at the time of this writing so it might change.
9. Test using irb
[root@csapp1 instantclient]# irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'oci8'
=> true
irb(main):003:0>
1. Read http://www.foliosus.com/2008/05/05/connecting-ruby-on-rails-to-oracle-on-an-intel-mac-in-leopard-take-2/
2. Install Oracle Instant Client on Mac.
a. Instant Client Package – Basic: All files required to run OCI, OCCI, and JDBC-OCI applications
- instantclient-basic-macosx-10.2.0.4.0.zip (34,020,719 bytes)
b. *Instant Client Package – SDK: Additional header files and an example makefile for developing Oracle applications with Instant Client
instantclient-sdk-macosx-10.2.0.4.0.zip (603,493 bytes)
OR download the whole bundle (10.2.0.4.zip) with sqlplus installed from my installers.
3. Put this on your sudo vim ~/.bash_profile.
export ORACLE_HOME=/Library/Oracle/instantclient/10.2.0.4
export TNS_ADMIN=$ORACLE_HOME
export LD_LIBRARY_PATH=$ORACLE_HOME
export DYLD_LIBRARY_PATH=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME
4. Make a symbolic link
cd /Library/Oracle/instantclient/10.2.0.4
ln -s libclntsh.dylib.10.1 libclntsh.dylib
5. Go to /Library/Oracle/instantclient/10.2.0.4 and edit tnsnames.ora. Point the Oracle SID to the IP where you installed Oracle.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.155)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
ORCL_2_11 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.11)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)6. Install the oracle-adapter for rails
sudo gem install activerecord-oracle-adapter --source http://gems.rubyonrails.org
7. In your database.yml file
development:
adapter: oracle
database: orcl
username: youzhu_mobile_dev
password: your_password
or browse the contents of a sample rails project youzhumobile.tar.gz
8. If you ever encounter an encoding problem, then we need to set the NLS_LANG environment variable before running script/server.
# export NLS_LANG=American_America.UTF8
# script/server
or I prefer setting it in the environment.rb
Rails::Initializer.run do |config|
ENV['NLS_LANG']='American_America.UTF8'
# Settings in config/environments/* take precedence over those specified here.
Note: If you don’t know your database encoding, then read this post.
1. I was trying to get the http headers dump from a mobile phone. So I quickly dump it in a log file to see its contents..
headers['Content-Type'] = 'text/xml; charset=utf-8'
for header in request.env.select {|k,v| k.match("^HTTP.*")}
logger.info(header[0].split('_',2)[1] + ":" + header[1])
endReference:
http://tonycode.com/wiki/index.php?title=Dumping_HTTP_Headers
2. However, please note that you can actually see everything from the request as parameters.
Parameters: {“MSAG-ADDRESS-PREFIX”=>”aSTARTa”, “format”=>”xml”, “protocol”=>”ussd”, “user-agent”=>”Jakarta Commons-HttpClient/3.0.1″, “WHOISD-ABONENT”=>”8613520747210″, “action”=>”menu”, “controller”=>”ussd”, “subscriberID”=>”8613520747210″, “WHOISD-USR”=>”-1″, “host”=>”wap.watago.mobi”, “WHOISD-USSD-MESSAGE”=>”", “content-length”=>”0″}
This means we can easily do..
@whoisd_abonent = params['WHOISD-ABONENT'] || nil

The get method kicks off the web request and populates the results into the response. It accepts 4 arguments:
*The action of the controller you are requesting. This can be in the form of a string or a symbol.
*An optional hash of request parameters to pass into the action (eg. query string parameters or post variables).
*An optional hash of session variables to pass along with the request.
*An optional hash of flash values.
Example: Calling the :show action, passing an id of 12 as the params and setting a user_id of 5 in the session:
get(:show, {'id' => "12"}, {'user_id' => 5})
