關於TOAD/plsql使用instantclient的設置

到Oracle官網下載Oracle Instant Client，注意選擇x86平臺，Toad只認32位的Oracle Instant Client。至於版本號，沒有特別要求，版本向下兼容。

桌面上，右鍵點「個人電腦」，選擇「屬性」，選擇「高級」頁中的「環境變量」，在系統變量中，修改以下

變量名：ORACLE_HOME
變量值：D:\Program Files\instantclient_11_2
變量名：TNS_ADMIN
變量值：D:\Program Files\instantclient_11_2
變量名：NLS_LANG
變量值：SIMPLIFIED CHINESE_CHINA.ZHS16GBK
修改Path變量，在後面添加 D:\Program Files\instantclient_11_2

在D:\Program Files\instantclient_11_2新建一個文本文件，文件名爲tnsnames.ora和sqlnet.ora

#orcl能夠自定義替換
#HOST修改成Oracle Server地址
#SERVICE_NAME修改成Oracle實例名
orcl =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.30.85)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = orcl)
        )
      )

# This file is actually generated by netca. But if customers choose to

SQLNET.AUTHENTICATION_SERVICES = (all)
#NAMES.DIRECTORY_PATH= (EZCONNECT)
NAMES.DIRECTORY_PATH= (TNSNAMES)
