How to connect PLSQL Developer to remote Oracle (non-installation client)

Remote connection to Oracle is troublesome. It usually takes the oracle client to be installed. You can use instantclient to easily connect to a remote Oracle database.

 

1. Create a Directory D: \ Oracle_Cleint to store related files. Create a Directory D: \ Oracle_Cleint \ NETWORK \ ADMIN to store tnsnames files.
2. Download the corresponding version and the system's instantclient compressed package, decompress the package to obtain the instantclient folder, and place the content in the folder under D: \ Oracle_Cleint.

Modify the preceding Oracle IP address.
5. Place the modified tnsnames. ora file in the D: \ Oracle_Cleint \ NETWORK \ ADMIN directory.
