Re: Oracle for Windows XP with INTEL inside

Graeme Farmer


Are you connecting to the host machine via RDP (MS Terminal Services
If so, you cannot connect via the method you described (unless you are on
MS Server 2003 and you specify connection to the CONSOLE when initiating
your RDP session).

Also, you cannot connect "system as sysdba" (unless you specifically grant
the SYSDBA privilege to SYSTEM which is not standard practice). You should
connect "SYS AS SYSDBA".

If you DO connect over RDP on <Win2003 then to connect as SYSDBA you will
need to start the listener, configure remote_login_passwordfile=exclusive
in the (s)pfile and connect "SYS@(protected)".

Good luck.

Oracle for Windows XP with INTEL inside

Hi guys,
Is that true that you cannot connect to Oracle 9.2.0 on Intel + XP machine

I got this from metalink


Problem: You could get an ORA-09352 on version 7.x of the database, an
ORA-12203 on version 8.0.x of the database, or an ORA-12560 on version
8.1.x of the database.

Solution: This is because the bequeath connection is not supported on NT
terminal server. Note 66397.1 (INTEL: Windows NT Terminal Server Support)
shows the certification.


Can you please tell me how to startup Oracle 9.2.0 wihtout using listener?
(on Win XP).

This is my attempt


run... cmd

C:\> set ORACLE_SID=mytest       (I also try set the variable on the
System Property, Advanced Tab, User variables)

C:\> sqlplus /nolog

SQL> connect system as sysdba
password:.... manager

ORA-12560: TNS: erro....


Thanks in advance
