Rails Note #12: Oracle on Intel Mac
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.
For Windows:
To install oracle_enhanced adapter
