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:
- Oracle_home =d:\instantclient_12_1
- Tns_admin = D:\instantclient_12_1
- 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.
