ORA-12514 When Attempting to Connect As Sysdba (Doc ID 340092.1)

Last updated on JANUARY 21, 2015

Applies to:

Oracle Net Services - Version 8.1.7.4 to 12.1.0.2 [Release 8.1.7 to 12.1]
Information in this document applies to any platform.
This problem can occur on any platform.
All sysdba connections which omit the Net service names.

Symptoms

Attempting to connect locally or via bequeath using the following:

sqlplus "/ as sysdba"

This yields an error:

ORA-12514:TNS:listener does not currently know of service requested in connect descriptor

The database is running.  This is a local or bequeath connection so we do not expect the listener is
handling this connection and yet it's throwing a listener error.
