TNS-01189: The Listener could not authenticate the user - host name: localhost
Anyone had this tns error before?
I am getting it on all four databases for one linux box, it either occurs for all databases in that box or no databases at all per box therefore it seems to be RHEL related I believe
Also only occurs when HOST=localhost
does not occur when HOST= IPAddress or name
11.2.0.4 single instance database
RHEL 6.7
Listener LOG for one DB
