JDBC TCPS Connections Do Not Failover For SCAN Listeners (Doc ID 1289244.1)

Last updated on MARCH 08, 2017

Applies to:

JDBC - Version 11.2.0.1.0 to 11.2.0.2.0 [Release 11.2]
Information in this document applies to any platform.

Symptoms


JDBC thin 11.2.0.1 and 11.2.0.2 connections over TCPS fail with the following error when one of the SCAN
listeners and associated VIP are disabled/stopped and do not fail over to the
other available SCAN listeners.

IO Error: The Network Adapter could not establish the connection
ORA-12541: TNS No Listener

JDBC TCP connections and sqlplus/OCI connections work as expected and failover correctly.
