linux下通過Instant Client訪問oracle輸出中文亂碼的解決辦法

1，設置NLS_LANG
export NLS_LANG=american_america.AL32UTF8

2，在rails中database.yml的設置
development:
adapter: oracle
database: XXX.XXX.XXX.XXX/service_name
username: your_name
password: your_password


3，測試oracle是否連通：
ruby -r oci8 -e "OCI8.new( 'your_name', 'your_password', 'XXX.XXX.XXX.XXX/service_name').exec( 'select * from your_table') do |r| puts r.join(' | '); end"
