First, download the Oracle client

: http://www.oracle.com/technetwork/topics/winsoft-085727.html

Current Latest Version

Version 12.1.0.2.0

Select the first instant Client for Microsoft Windows (32-bit) to download it,

Please do not download 64bit, I have tried, can not achieve the connection.

Unzip the downloaded Instantclient-basic-nt-12.1.0.2.0.zip compressed package and put it in the D:\instantclient_12_1 directory.

In the environment variables, in the system variables, add:

1. Oracle_home =d:\instantclient_12_1
2. Tns_admin = D:\instantclient_12_1
3. Nls_lang = Simplified Chinese_china. Zhs16gbk

Modify the path variable and add D:\instantclient_12_1 later

ii. installation of PL/SQL Developer

Install the previously downloaded PL/SQL Developer (not downloaded on-line), but you need to emphasize that there are no brackets in the installation path and do not install under the C:\Program Files (x86) directory .

Third, the configuration of PL/SQL Developer:after the installation is complete, run PL/SQL Developer, the login form that appears cannot log in, click the Calcel button, you will enter without login.

Configure the appropriate information to configure the previous decompression package information:

Oracle Home = D:\instantclient_12_1

OCI Library =D:\instantclient_12_1\oci.dll

The three-step configuration is complete.
