I installed Oracle 11G on my Windows 2008 R2 Server. I also installed Oracle Client Libraries using separate installation media. After the client installation, when I try to log into the database using:
C:\>sqlplus / as sysdba
I get a following error:
ORA-01031: insufficient privileges
This worked before the client installation. My account is on the
ORA_DBA group. My account is also in the Administrator group. I don't have
ORACLE_SID set in my environment variables list. Does it have to be? This worked before the client installation, and I did not have that variable at that time either.
UAC is on at the lowest level, and I always run
cmd as admin.
I have an
sqlnet.ora file like this in the folder:
# sqlnet.ora Network Configuration File: C:\app\myaccount\product\11.2.0\dbhome_1\network\admin\sqlnet.ora # Generated by Oracle configuration tools. # This file is actually generated by netca. But if customers choose to # install "Software Only", this file wont exist and without the native # authentication, they will not be able to connect to the database on NT.

From the windows registry (using regedit), from the path
Computer > HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > ORACLE I can find two keys:
And under those keys I can find
ORACLE_HOME variables. So it seem that the client installation generated also
ORACLE_HOME so that I have now two
ORACLE_HOMEs. I don't know if this has something to do with this problem?
How to resolve this error on my Windows machine?
