The VS2008 c/s application is generated by connecting the Oracle database with ADO.

Solution Summary:

Installing the Instantclient_11_2 file

Implementation steps:

1. Extract the instantclient_11_2 to the Oracle Client installation directory. Note that the directory to be placed is ... app\administrator\product\11.2.0 as shown:

2. Modify the component configuration

In the extracted folder Instantclient_11_2 root, create a new folder named Network, and then in the root directory of the network folder, create a new folder named Admin.

Copy all the files in the Oracle Client installation directory ... app\administrator\product\11.2.0\client_1\network\admin to the previously created Admin folder.

3. Modify the environment variable path

Edit the system variable path, place the ... \app\administrator\product\11.2.0\instantclient_11_2 directory at the front of the PATH variable,

Remember to copy the past and add a semicolon to differentiate it from the values of other path variables. The system can be restarted at the end.
