1. Install Oracle Clinet
First download an Oracle 11g Client to the Oracle website, but you will need to apply for an Oracle account before you can download it.
Current: http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
This is a green version of Oracle Client, so as long as it needs to be decompressed, it can be. Unzip the downloaded Oracle client file Instantclient-basic-win32-11.2.0.1.0.zip to the C drive (note!). Cannot be under 64-bit). Then create a new network\admin directory under the extracted C:\instantclient_11_2 directory, create a new Tnsnames.ora file in the Admin directory, and add the database TNS.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = chiclewu-pc) (PORT = 1521))
(Connect_data =
(SERVER = dedicated)
(service_name = ORCL)
)
)
(Note: The Tnsnames.ora file can also be copied from the Network\admin directory of the Oracle database home directory, as well as the Sqlnet.ora.) Then determine whether the host configuration is correct, if host is the hostname, you need to remove the domain name after the hostname)
2. Oracle Home and OCI libaray configured with PL/SQL developer
Enter the PL/SQL Developer in non-logon mode, designate the Oracle home path as the Oracle Client directory (C:\instantclient_11_2), and the OCI Libaray path to Oracle The Oci.dll (C:\instantclient_11_2\oci.dll) of the client directory.
Click "OK" and now the configuration is complete, here is the time to wait for a miracle. Exit PL/SQL Developer.
3. Verifying Oracle Client
Open a new PL/SQL Developer, enter the user name and password, under the database option, you can see the TNS that has just been configured.
Waiting for the miracle moment ....
After a few seconds of waiting, the miracle time has finally arrived, you can login, you can login ...
Check to see if the data can be queried.
Query data no problem, finally finished.
