Hello all,

I am running Oracle 9.2 on Windows XP Professional, I usually start the listener and database using the Services dialog box in Control Panel, but today decided to use the command prompt - I know what a krazy kid eh?

I started the listener using:
lnsrctl start
command and then attempt to log on to the database using sqlplus as the sys user with sysdba priviliges, however I get the following error message:

ORA-12500: TNS:listener failed to start a dedicated server process

Why can I not just execute:
sqlplus /nolog
conn sys@DEV01 AS sysdba
and then issue a startup command? Why do I have to execute: 
net start OracleServiceDEV01


Many Thanks

Andy

Memory? Limits?

Post your configuration ( amount of memory, size of SGA, etc...) and metrics. This will help in analyzing your problem.
