then SQL*Net and Listener is NOT required to connect to the database.
6) "ping axel-0560nntbn1"

4) ORA-12514 error: I doubleklick on the database icon of MYDB I just
added to the tree to open it! There is a pre-configured database
called "oracle" in the tree. When I click on this one it changes into
"oracle - Axel as sysdba" and opens.
5) I run Oracle 9i on my laptop, so I am logged onto the database
server system DIRECTLY. You say a Listener is NOT required to connect
to a database directly. But why do I get bothered by this ORA-12514
error ?
6) ping statistic for 172.0.0.1:
response from 172.0.0.1: Bytes = 32 time <1ms TTL 128
(4 times)
package: sent = 4 got = 4 lost = 0
7)lsnrctl status produces these Services:
-----------------------
Dienst "PLSExtProc" ...
Dienst "oracle.localhost" ...
Dienst "oracleXDB.localhost" ...
--------------------------
obviously there is no service running for MYDB !?
Thanks Axel
