It's really difficult to read what you posted ...
Why, in the last line of "code" you have
a space embedded in the middle of your port number?
Why are you running a listener on a non-default port?
Are you trying to run multiple listeners on this database server? (From your problem description, it sounds so). If so, why?
EXACTLY what command did you issue that resulted in 'ORA-12541'
Whatever it is, I guarantee it will come back to something discussed here: Help! I can&#8217;t connect to my database &#8230; | Ed Stevens, DBA

waiting for you to post readable COPY & PASTE results showing what you do & how Oracle responds
How do I ask a question on the forums?
since you mentioned oradim, I will assume you are working on some sort of Windows OS.
before you can start any database on Windows, it requires two OS services (1 for the database & 1 for the listener) to be started & running at the OS level.
please show us that they now exist for your system.
Firstly I'm so sorry about my asking mistake.
I know i should have 2 services.
Any way the problem solved after restarting services and trying to connect again..
Many thanks for your help.
