Download link: http://download.csdn.net/detail/pioayang/7236231
Copy it to the plsql installation directory after downloading;
Note: I have not verified this link. If it is not available, try to download it from other websites. The downloaded file should be a folder after decompression, no installation is required, just copy the folder to the specified directory.
3. Open the plsql client and enter Tools-Preferences-Oracle-Connection in turn,
Fill in the oracle client directory in the text box under Oracle Home, such as: D:\Program Files (x86)\PLSQL Developer\instantclient_12_1
Fill in the OCI.dll path in the oracle client directory in the text box under OCI library, such as: D:\Program Files (x86)\PLSQL Developer\instantclient_12_1\oci.dll
Click Apply, click OK;
4. Restart the plsql client and check whether the path in the previous step is still there. If not, repeat step 3 until plsql can display the configured path;
5. Enter the correct user name, password, database information (ip/db name), click OK, and log in normally.
