Unable to connect from a JDBC Thin Driven Application to 19c Database when Security Banner is set in the RDBMS home sqlnet.ora file (Doc ID 2814594.1)

Last updated on OCTOBER 15, 2021

Applies to:

Oracle Database - Enterprise Edition - Version and later
Information in this document applies to any platform.


You may find that you cannot connect to a 19c Database from a JDBC Thin driven application (even occurs with OEM) and either of the following sqlnet.ora file parameters are set:

sec_user_audit_action_banner= <txt file>
sec_user_unauthorized_access_banner=<txt file>

A common error on the JDBC side is:


The JDBC Thin Driver is 18c or lower.


This may have been an upgrade of the Database to 19c and addition of the Security Banners in the sqlnet.ora file.
