(Doc ID 1289244.1)

Last updated on MARCH 08, 2017

Applies to:

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


JDBC thin and 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.
