Connecting as sysdba returns ORA-01017: invalid username/password
842271Dec 3 2011 — edited Dec 5 2011SQL Developer on my Win7 x64 Enterprise machine with Oracle 11gR2 Express was working fine until I tried to install the ODAC connectors so I could use Oracle as a data source for C# and VB in Visual Studio 2010.
The connection properties are:
Connection name "/ as sysdba"
Role "default"
Connection Type "basic"
OS Authentication checked
Hostname "localhost"
Port 1521
SID "orcl"
These are the same as when SQL Developer was working.
If I try to log on to SQL*Plus at the user-name prompt with "/ as sysdba", I get "insufficient privileges".
Where and what do I check to fix this?
Thanks.
