Newbee: ORA-27101: shared memory realm does not exist

[Christian Ruediger]

Hello folks,

i am new to oracle so i'm sorry if my question is trivial.
I have Installen Oracle 8.1.7 successful on a SUN SOLARIS System.
Now i would like create a new database manually as describes in the
Administrators Manual. Thus i am trying to get connectet with sqlplus.
So here is my Problem:
Each time I'd like to connect in sqlplus I get the following
Error-Message:
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
SVR4 Error: 2: No such file or directory

I discovered that I get this Message independent of the username and
password i inserted before. So i assumed that my user password
combination is not known to oracle.
How do get get to know which users exist for oracle administration?
Or has anyone an Idea why i cant connect.

I've searched the net for answers but i havent found any matches yet.

This is what i did to connect:

bash-2.03$ ./sqlplus /nolog

SQL*Plus: Release 8.1.7.0.0 - Production on Tue Jan 20 16:18:28 2004

My Question is already answered.
I didnt start the instance.
The following lines fixed that:

sqlplus /nolog
connect / as sysdba
startup
exit
