ORA-03114: not connected to ORACLE When connecting from 12c Linux client
I am having an issue connecting from a 12c(12.1 or 12.2) Linux client to our 12.1.0.2 Linux database.
I can connect successfully but when I run any command I get ORA-03114:
[xyz@logging ~]$ sqlplus xyz/xyz@ouxyz3

The error occurs on all of our Linux 12c clients when using SQLPLUS. Works fine from 11.2 Linux client, 12c clients on windows and SQLDeveloper.
