ORA-28547 Error Using ODBC Application or Net Manager (Doc ID 1080521.1)

Last updated on FEBRUARY 27, 2019

Applies to:

Net Manager - NetMgr - Version to [Release 10.2]
Oracle ODBC Driver - Version to
Microsoft Windows x64 (64-bit)
Microsoft Windows (32-bit)
This problem is limited to a client / server installation running on a Windows platform.


An application using the ODBC driver fails to connect.  The error returned to the screen is: 

ORA-28547: connection to server failed, probable Oracle Net admin error.

The ODBC DSN test button yields the same error. 

The same error may be reproduced using the Net Manager tool to create and test a service.  If Net Manager is running in the same home as the ODBC client.

This problem will not likely reproduce using SQL*Plus from the same ORACLE_HOME.


A recent upgrade to 10g may have taken place or this is a new installation.
