1. Log in to PL/SQL Developer

This omits the installation steps for the Oracle database and PL/SQL Developer, and note that when you install the PL/SQL Developer software, do not install it under the program Files (x86) directory or you cannot start PL/SQL Developer.

Wonder why the database TNS is not chosen here? I installed the database first and then installed PL/SQL Developer. When the PL/SQL developer is installed, Oracle home and OCI Libaray have been identified. What about it? Log in to PL/SQL Developer with non-login first, set up Oracle home and OCI Libaray.

The Oracle home directory is not automatically recognized under Oracle home, and the Oracle home path is manually specified.

Click "OK" to exit PL/SQL Developer and log in again.

Or choose not to database TNS, try to log in without a database to see what errors are reported.

Finally found the key point of the problem, the installation of PL/SQL Deleloper can only recognize the 32 oci.dll. It seems to be a 64-bit PL/SQL Deleloper, so search the web for PL/SQL Deleloper 64-bit version. However the Discovery PL/SQL Deleloper does not differentiate between 64-bit and 32-bit. It seems that we can only start with Oci.dll. According to the above error message, it appears that just install a 32-bit version of Oracle Client.

2. 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)

3. Configuring the Oracle Home and OCI libaray for 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.

4. 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.
