Oracle Database Express Edition (XE)

Okay,

I hate to be that newbie that post a message that has been posted oh so many times.

I am having similar problems as a lot of other people. This assumptions based on the number of entries with the same problem. I have gone through these entries with no success. I followed the instructions down to the last detail. I am running IE 7.0.5. That may be my problem.

I can start my database from my start menu. However I try to connect to the database and it says the following.

SQL> connect
Enter user-name: SYSTEM
Enter password:
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

I also tried SYSDBA & SYS. I got these user names from the setup. It said assign your SYSTEM & SYS passwords.

I have started all services that have anything to do with Oracle in my service list.

Restarted my machine.

I have noticed that a lot of people in response ask for the listener status. Here ya go.

LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC_FOR_XE)))

I am running Windows XP Service Pack 2.

Any help would be great. Thanks
