無法將我的Rails應用程序連接到Oracle

我有一臺運行Oracle的服務器，IP爲192.168.1.50。無法將我的Rails應用程序連接到Oracle

在我的Linux機器上，我需要連接到這個Oracle服務器。然後我安裝了Oracle即時客戶端，並相應地設置環境變量：

OCI_INCLUDE_DIR = /家庭/ LUC/instantclient_11_2/SDK /包括
LD_LIBRARY_PATH = /家庭/ LUC/instantclient_11_2
DYLD_LIBRARY_PATH = /家庭/ LUC/instantclient_11_2/
OCI_LIB_DIR = /家庭/ LUC/instantclient_11_2
ORACLE_HOME = /家庭/ LUC/instantclient_11_2

我也安裝了相應的寶石：

ruby-oci8 (2.1.0)

一旦我確定我的模型，跑耙分貝：遷移，我得到了以下錯誤消息：

rake aborted! 
ORA-12154: TNS:could not resolve the connect identifier specified 
oci8.c:360:in oci8lib_191.so 
/home/luc/.rvm/gems/ruby-1.9.3-p125/gems/ruby-oci8-2.1.0/lib/oci8/oci8.rb:123:in `initialize'

....

我的database.yml是：

development: 
    adapter: oracle_enhanced 
    host: 192.168.1.50:1521/orcl 
    username: USER 
    password: PASS

sqlplus的連接完美的作品，但：

sqlplus USER/[email protected]:1521/orcl 

SQL*Plus: Release 11.2.0.3.0 Production on Wed Mar 21 17:34:26 2012

Connected to: 
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

SQL>

在這個配置文件中是否缺少某些東西？

UPDATE

我已經從命令行測試，並在連接工作正常：

紅寶石-rubygems -e「需要 '的oci8'; OCI8.new（ '用戶'， 'PASS' ， '192.168.1.50/ORCL'）執行（「SELECT * FROM用戶）做的| r |提出r.join（ ''）;結束」

=> OK

同樣從IRB的事情：

ActiveRecord::Base.establish_connection(:adapter => "oracle_enhanced", :database => "//192.168.1.50/orcl",:username => "USER",:password => "PASS")

=>好吧

但仍然不能從我的rails應用程序工作。

使用數據庫，而不是主機固定的東西：

development: 
    adapter: oracle_enhanced 
    database: //192.168.1.50:1521/orcl 
    username: USER 
    password: PASS

我都定義;刪除主機解決了這個問題。 – tamersalama 2016-01-13 20:42:49

如果你想使用EZCONNECT語法來連接到Oracle，在database.yml文件host需要包括前導斜槓，即

host: //192.168.1.50:1521/orcl

有例子在此OTN文章Connecting to Oracle in Ruby on Rails中配置Rails訪問Oracle數據庫的其他方法。
