How to Limit the Connection Type for Database Connections from SQL Developer (Doc ID 2289074.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle SQL Developer - Version 4.0 and later
Information in this document applies to any platform.


A security requirement exists to restrict the type of connections made from SQL Developer to the database to 12c connections. The database server has the following configuration entries in the sqlnet.ora to ensure only 12c connections:

SQLNET.ALLOWED_LOGON_VERSION_SERVER (See Oracle Database Net Services Reference for information)
SQLNET.ALLOWED_LOGON_VERSION_CLIENT (See Oracle Database Net Services Reference for information)

However, this still allows SQLNet thin client connections from SQL Developer 17.2. Is it possible to restrict SQL Developer so that it allows only connections using the instant client or TNS connection type?
