PL/SQL Developer 11 64bit 安装和配置

安装后,
1. 解压 instant client 到plsql developer 的安装目录
    注意, 此版本只支持 instantclient_11_x, 不支持 instantclient_12_x, 如果使用12_x的会报dll错误
2. 在 instant client 目录下创建 network/admin 目录
3. 创建 tnsnames.ora 文件, 写入内容格式如下

# Generated by Oracle configuration tools.

DB_DEV =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 33.5.126.211)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = ORC)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

4. 设置桌面快捷方式的属性, 加入如下参数, 就可以不需要再设置环境变量

"C:\Program Files\PLSQL Developer\plsqldev.exe" instantclient="C:\Program Files\PLSQL Developer\instantclient_11_2" nls_lang=AMERICAN_AMERICA.AL32UTF8

5. 其中的nls_lang 参数, 可以通过查询数据库得到, sql为

select userenv('language') nls_lang from dual;
