PLSQL Developer连接64位Oracle

首先介绍下环境

服务器上安装好64位Oracle 12c最新版本；

客户端安装64为Oracle Client 12c;(安装路径C:\app)

客户机下载解压Oracle intantclient_11_2(安装路径C:\app\aa\product\instantclient_11_2,这个随意)

客户机安装PL/SQL Developer 11

1.下载64位Oracle Client 12c安装。

2.下载Oracle instantclient_11_2安装,切记是11.2版本,本人之前在英文官网下的32位的12版,连接提示不是32位错误。

在\instantclient_11_2目录下，建两个文件夹\network\admin,建tnsnames.ora文件。

内容如:

<span style="font-size: 18px;">#TEST前面不能有空格，否则报错连不上。</span>

TEST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
TEST2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
TEST3 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.2)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)

3.下载PL/SQL Developer 11版安装http://files.allroundautomations.com/plsqldev1104.exe

4.在PL/SQL Developer选项中设置

Oracle Home=C:\app\aa\product\instantclient_11_2\

OCI library=C:\app\aa\product\instantclient_11_2\oci.dll

*5.环境变量path=C:\app\aa\product\12.1.0\client_1\BIN;保持默认不改。（搜出来一大堆要设环境变量，没用。）
